* Introduction

#+BEGIN_VERSE
/If you look at it from an engineering perspective, an iterative perspective, it’s clear that you have to try something rather than do nothing./

-- Edward J. Snowden
#+END_VERSE

** What is FreedomBone?
Today many of us rely upon "free" services in the cloud, such as Gmail, Facebook, Google+ and so on.  It might appear that these services are indispensible infrastructure of the modern internet, but actually they're not strictly needed and the amount of value which they deliver to the average internet user is very marginal.  It is possible to be a citizen of the internet and yet not use those things - to disintermediate the most well known companies and cut out their prurient or merely cringeworthy business models.

FreedomBone is a personal home communications server based upon the BeagleBone Black hardware.  It's small and cheap and will allow you to use email, have your own web site and do social networking in a federated way without needing to rely upon any intermediary companies other than your ISP.
** Do I need any prior knowledge?
In these instructions only a minimal level of familiarity with Linux is assumed.  It's assumed that you know the basics of the /nano/ and /emacs/ editors, but it would be simple to also use other editors if you prefer.
** Why should I do this?
You should consider doing this if you are a freedom-oriented sort of person and you want to maintain sovereignty over your information.  Laws in many places in the world consider you to have relinquished any property rights over data which you put onto a server not owned by youself (i.e. owned by a third party, such as Google or Facebook).

If you don't like the idea of having all your communications intercepted and investigated by the Surveillance State then you should consider running a FreedomBone.  If your profession involves maintaining confidentiality as an essential feature, such as legal or medical services, counselling, teaching or any sort of activism then you should consider running a FreedomBone.

As Eben Moglen noted in his now famous [[https://www.youtube.com/watch?v=QOEMv0S8AcA]["Freedom in The Cloud"]] talk the simple fact of you keeping your own internet logs (found in the /var/log directory) puts a certain amount of power in your hands and takes it away from parties who would otherwise sell that information without your knowledge or permission to advertisers or other shady outfits who may not have your best interests at heart.
** After it's installed will it need a lot of maintenance?
So long as the hardware is ok the amount of maintenance needed should be very small.  Unlike on Windows based systems you don't need to defragment drives or mess about with anti-virus programs.  I ran a similar Sheevaplug system between 2010 and 2013 with only occasional software updates or reboots, and uptime was probably 99% or better.
** Is it secure?
Nothing is totally secure or infallible.  You could have the most secure technology and yet still use easy to guess passwords.  This system will not defend you from an attacker who is actively trying to block or corrupt your communications, but I assume that doesn't apply in the majority of cases.  Another thing to be aware of is that running a FreedomBone could make you more vulnerable to traffic analysis, since the server is associated with your home address and isn't a giant aggregation of users somewhere in the cloud.  You need to weigh this alongside the additional legal protection which owning the server and having it in your own home gives you.

FreedomBone should be far more secure than using popular cloud-based services which have spying built into them as a core feature (although not one which is typically advertised), but it is not necessarily an impenetrable information fortress.  This project is at least as much about achieving communications independence as it is about being able to do that securely.
** Will running a server all the time affect my electricity bill?
Hardly at all.  The BeagleBone Black consumes very little power - less than 5W.  It would even be potentially possible to run it from a solar panel.

/You can’t help someone just by making a wish to do so, you have to take action./

-- Dalai Lama
#+END_VERSE

These instructions assume that you have the following ingredients.

** A BeagleBone Black (BBB)

It should come with a suitable USB cable for the initial setup.  To make things look nicer you may also want to get a case for it.

** An internet connection

It is assumed that the most common situation is via a router installed at home. The router should have ethernet sockets on it and a web interface which allows you to forward ports (sometimes under the "firewall" settings), so that you can forward ssh and web traffic to the BBB.

** microSD card

To use as the main storage for the BBB.  16 or 32GB is fine, and can be obtained quite cheaply.  Try to use Sandisk (class 10 or better) where possible and avoid cheaper cards which often have poor performance.

You may also need an SD card adaptor or USB card reader in order to flash the operating image to the microSD card.  For instance, many laptops have an SD card slot but not a microSD slot.

** 5V/1A power supply

With a plug suitable for powering the BBB.  If you have some device with a USB socket nearby you may also be able to just use that for electrical power.  However, powering from the USB cable alone might result in crashes when the system is under load, depending upon how many milliamps can be supplied by the USB hub/socket.  If the system crashes due to running out of power then you will see that the LEDs on the BBB are continuously on, rather than flashing.

** An ethernet patch cable

Just an ordinary cat5 or cat6 cable that you can get from most electrical/computer stores.

* Installing Debian onto the microSD card

The Debian Linux OS will be installed onto a small flash drive.  It's a good idea to do this rather than using the internal flash, because it will allow you to easily create backups of the entire system if necessary using the dd command.

Download the image.

#+BEGIN_SRC: bash
cd ~/
wget http://freedombone.uk.to/debian-7.2-console-armhf-2013-11-15.tar.xz
#+END_SRC

Verify it.

#+BEGIN_SRC: bash
md5sum debian-7.2-console-armhf-2013-11-15.tar.xz
0a448f55d14f64c5a7eb3d7cb2c54185  debian-7.2-console-armhf-2013-11-15.tar.xz
#+END_SRC

Uncompress it.

#+BEGIN_SRC: bash
tar xJf debian-7.2-console-armhf-2013-11-15.tar.xz
cd debian-7.2-console-armhf-2013-11-15
#+END_SRC

Create the disk image, where sdX is the name of the flash drive (probably it will be sdb or sdc).

#+BEGIN_SRC: bash
sudo apt-get install u-boot-tools
sudo ./setup_sdcard.sh --mmc /dev/sdX --uboot bone --swap-file 1024
#+END_SRC

Once completed then safely remove the microSD card via your file manager (usually right click and "safely remove" or "eject").

* Setup

#+END_VERSE

** Things to be aware of
*** A note on ssh
When using ssh to log into the BBB if you get warnings of the type "/the ECDSA host key for domain differs from the key for the IP address/" then run the command:

#+BEGIN_SRC: bash
ssh-keygen -R <IP address>
#+END_SRC
*** Passwords
It's highly recommended that you use a password manager, such as KeepassX, and make all your passwords long random strings.  It's also a good idea to use different passwords for different pieces of software, instead of one or two passwords for the whole system.  That compartmentalises the security such that even if an attacker gains access to one system they can't necessarily get access to others.
*** HTTPS
Throughout these instructions self signed SSL certificates are used to implement access to web pages via HTTPS.  The whole HTTPS security model upon which much of the internet currently rests seems broken in that it usually depends upon "trusted certificate authorities" who are not really trusted, except perhaps by the maintainers of certain web browser software.  So all that HTTPS really guarantees is that you have an encrypted connection, but an encrypted connection /to who/ can be subject to doubt.  As was seen in 2013 with the [[https://www.schneier.com/essay-455.html][information coming from Edward Snowden]], and also the [[http://en.wikipedia.org/wiki/Lavabit][Lavabit email service]], it's possible for companies/organisations to be compromised or bribed and SSL private keys for all users can be demanded using gagging orders or secret laws without any individual user ever being able to know that their communications is no longer secure..

Not knowing who you're really connecting to is especially true for self-signed certificates, so it is in principle possible that when logging into a site with a username and password a system such as [[http://arstechnica.com/tech-policy/2013/11/uk-spies-continue-quantum-insert-attack-via-linkedin-slashdot-pages/][Quantum Insert]], or a compromised [[http://en.wikipedia.org/wiki/Domain_Name_System][DNS service]], could be used to direct the user to a fake copy of the login screen for the purposes of obtaining their login details.  While this doesn't seem to be a major problem at the time of writing it's something to keep in mind.  So if you can't log in or if you log in and what you see doesn't look like your site then it's possible that such a compromise could have taken place.  Using a password manager with different login details for each site is one way to ensure that if one system is compromised then the attacker can't necessarily get access to all your other stuff.
** Initial

Plug the microSD card into the BBB and Connect the USB cable to your laptop/desktop, then login via ssh.

#+BEGIN_SRC: bash
ssh debian@192.168.7.2
#+END_SRC

The default password is /temppwd/

Then log in as root:

#+BEGIN_SRC: bash
su
#+END_SRC

The default password is /root/

The first thing to do is to change the passwords from their defaults.

#+BEGIN_SRC: bash
passwd
#+END_SRC

Then you will need to change the network interfaces.  The main task here is to comment out the stuff related to usb0.  That will enable you to plug the BBB into the back of a router and for it to be detectable on the network.

#+BEGIN_SRC: bash
nano /etc/network/interfaces
#+END_SRC

The resulting interfaces file should look like this:

#+BEGIN_SRC: bash
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug eth0
iface eth0 inet static
    address 192.168.1.60
    netmask 255.255.255.0
    gateway 192.168.1.254
    dns-nameservers 213.73.91.35 85.214.20.141
# Example to keep MAC address between reboots
#hwaddress ether DA:AD:CE:EF:CA:FE

# WiFi Example
#auto wlan0
#iface wlan0 inet dhcp
#    wpa-ssid "essid"
#    wpa-psk  "password"

# Ethernet/RNDIS gadget (g_ether)
# ... or on host side, usbnet and random hwaddr
# Note on some boards, usb0 is automaticly setup with an init script
# in that case, to completely disable remove file [run_boot-scripts] from the boot partition
#iface usb0 inet static
#    address 192.168.7.2
#    netmask 255.255.255.0
#    network 192.168.7.0
#    gateway 192.168.7.1
#+END_SRC

CTRL-O followed by ENTER to save, then CTRL-X to exit.

In the above example "address 192.168.1.60" is a static IP address for the BBB, which will allow incoming network traffic to be directed from the router in a reliable manner.  It should be outside of the DHCP range set up on the router.

"gateway 192.168.1.254" should be the IP address of the router.

Note that setting the DNS servers with dns-nameservers is important because some home routers do not allow you to change the DNS settings.

Edit resolv.conf.

#+BEGIN_SRC: bash
nano /etc/resolv.conf
#+END_SRC

It should look something like the following:

#+BEGIN_SRC: bash
domain localdomain
search localdomain
nameserver 213.73.91.35
nameserver 85.214.20.141
#+END_SRC

CTRL-O followed by ENTER to save, then CTRL-X to exit.

Now disconnect the BBB from your computer and plug it into the router.  You'll need an ethernet patch cable and you may also need a 5V/1A power supply for the BBB.

If you go to the web administration screen for your internet router (often it's on 192.168.2.1 or 192.168.1.254) then after a few minutes you should see the BBB appear on the network.  It's name will be "arm".

** Add a user

Ssh back in to the BBB and login as root.  In this example the BBB's IP address is 192.168.1.60.

#+BEGIN_SRC: bash
ssh-keygen -f "/home/myusername/.ssh/known_hosts" -R 192.168.1.60
ssh debian@192.168.1.60
su
#+END_SRC

Then make a new user.  It's a bad idea to add users to the sudo group, because that then means that an attacker potentially only needs to know one password in order to get administrator access to the system.  With no sudoers an attacker needs to know, or be able to obtain, two separate passwords to be able to really compromise the system.

#+BEGIN_SRC: bash
adduser myusername
#+END_SRC

Exit from the ssh login by typing "exit" a couple of times, then ssh back in as the new user.  Make sure you use a difficult to guess password/phrase, or ideally a randomly generated password used together with a password manager such as KeepassX.

Remove the default debian user.

#+BEGIN_SRC: bash
userdel -r debian
#+END_SRC

** Text editor

For an editor which is less erratic than vi when used within a remote console such as Terminator.

#+BEGIN_SRC: bash
apt-get update
apt-get install emacs
#+END_SRC

Some basic Emacs keys which will be useful to new users are:

| Load a file | CTRL-x CTRL-f |
| Save        | CTRL-x CTRL-s |
| Exit        | CTRL-x CTRL-c |

** Create a swap file

Without a swap file the system may occasionally run out of memory and crash, since the Beaglebone only has 512MB of RAM.  The following commands will create a 1GB swap file:

#+BEGIN_SRC: bash
mkdir -p /var/cache/swap/
dd if=/dev/zero of=/var/cache/swap/swapfile bs=1M count=1024
chmod 600 /var/cache/swap/swapfile
mkswap /var/cache/swap/swapfile
swapon /var/cache/swap/swapfile
#+END_SRC

To tell the OS to load this swapfile on each start up.

#+BEGIN_SRC: bash
emacs /etc/fstab
#+END_SRC

Append the following line:

#+BEGIN_SRC: bash
/var/cache/swap/swapfile    none    swap    sw    0   0
#+END_SRC

Then save and exit.

To verify that the swapfile is accessilble type /top/ and look for the line which begins with "KiB Swap".  Probably there will be zero bytes used, but this might be non-zero when the system is under some load (for example getting a lot of web views or being crawled by a search engine).  CTRL-C exits from the /top/ command.

** Enable backports

To enable some newer packages add backports to the repositories.

#+BEGIN_SRC
echo "deb http://ftp.us.debian.org/debian wheezy-backports main" >> /etc/apt/sources.list
apt-get update
apt-get dist-upgrade
#+END_SRC

** Random number generation

#+BEGIN_VERSE
/Near as I can tell, the answer on what has been requested is everything: deliberate weakenings of encryption algorithms, deliberate weakenings of random number generations, copies of master keys, encryption of the session key with an NSA-specific key … everything./

-- Bruce Schneier, on the 2013 leaked NSA documents
#+END_VERSE

The security of encryption depends upon how random the pseudo-random number generation on your system is.  If it isn't very random then it may be far more vulnerable to cryptanalysis, and it's known that in the past some dubious agencies have encouraged the use of flawed random number generators to assist with their prurient activities.  Randomness - typically referred to as /entropy/ - is often gathered from factors such as the timing of key presses or mouse movements, but since the BBB won't have such devices plugged into it this reduces the amount of entropy available.

To improve entropy generation there are two options.  One is to install a kernel module which enables the hardware crypto available on the BBB, but that's a bit complicated and might have some stability implications.  The other option is to install [[http://www.issihosts.com/haveged/][havegd]].  While not as good as a true hardware random number generator, havegd is better than the default pseudo-random number generation within the Linux kernel.  To install it:

#+BEGIN_SRC: bash
apt-get install haveged
#+END_SRC

At the time of writing there is also some hardware called [[http://beagleboard.org/project/CryptoCape/][cryptocape]] being developed, with the intention of adding extra random number generation capabilities to the BBB.

** Alter ssh configuration

Altering the ssh configuration will make it a little more secure than the standard Debian settings.

#+BEGIN_SRC: bash
emacs /etc/ssh/sshd_config
#+END_SRC

Check the following values:

#+BEGIN_SRC: bash
PermitRootLogin no
X11Forwarding no
ServerKeyBits 4096
Protocol 2
PermitEmptyPasswords no
StrictModes yes
#+END_SRC

Append the following:

#+BEGIN_SRC: bash
Ciphers aes256-ctr,aes192-ctr,aes128-ctr
MACs hmac-sha2-512,hmac-sha2-256,hmac-ripemd160
KexAlgorithms diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha1,diffie-hellman-group-exchange-sha1
#+END_SRC

CTRL-X CTRL-S to save, then CTRL-X CTRL-C to exit.

#+BEGIN_SRC: bash
service ssh restart
#+END_SRC

To test the new settings log out by typing "exit" a couple of times, then log back in again with:

#+BEGIN_SRC: bash
ssh -vvv myusername@192.168.1.60
#+END_SRC

and check that some number of bits are set within a 4096 bit sized key:

#+BEGIN_SRC: bash
debug2: bits set: */4096
#+END_SRC

** Set the host name

#+BEGIN_SRC: bash
emacs /etc/hostname
#+END_SRC

CTRL-X CTRL-S to save, then CTRL-X CTRL-C to exit.

also issue the command

#+BEGIN_SRC: bash
hostname /myhostname/
#+END_SRC

You may also need to assign the same hostname separately via your router's web interface.

** Install NTP

To synchronise time.

#+BEGIN_SRC: bash
apt-get install ntp
#+END_SRC

** Install fail2ban

#+BEGIN_SRC: bash
apt-get install fail2ban
#+END_SRC

** Set up a firewall

#+BEGIN_VERSE
/The documents, from a PowerPoint presentation prepared for a 2012 NSA conference called SIGDEV, show that the unit known as the Joint Threat Research Intelligence Group, or JTRIG, boasted of using the DDOS attack – which it dubbed Rolling Thunder/

-- NBC News article: /War on Anonymous: British Spies Attacked Hackers, Snowden Docs Show/
#+END_VERSE

A basic firewall limits the maximum rate at which connections can be made, and this helps to defend against various kinds of DDOS attack.

#+BEGIN_SRC: bash
emacs /tmp/firewall.sh
#+END_SRC

Enter the following:

#+BEGIN_SRC: bash
#!/bin/bash
# Limit the number of incoming tcp connections
# Interface 0 incoming syn-flood protection
iptables -N syn_flood
iptables -A INPUT -p tcp --syn -j syn_flood
iptables -A syn_flood -m limit --limit 1/s --limit-burst 3 -j RETURN
iptables -A syn_flood -j DROP
#Limiting the incoming icmp ping request:
iptables -A INPUT -p icmp -m limit --limit  1/s --limit-burst 1 -j ACCEPT
iptables -A INPUT -p icmp -m limit --limit 1/s --limit-burst 1 -j LOG --log-prefix PING-DROP:
iptables -A INPUT -p icmp -j DROP
iptables -A OUTPUT -p icmp -j ACCEPT
#+END_SRC

Save and exit

#+BEGIN_SRC: bash
chmod +x /tmp/firewall.sh
. /tmp/firewall.sh
iptables-save > /etc/firewall.conf
echo "#!/bin/sh" > /etc/network/if-up.d/iptables
echo "iptables-restore < /etc/firewall.conf" >> /etc/network/if-up.d/iptables
chmod +x /etc/network/if-up.d/iptables
rm /tmp/firewall.sh
#+END_SRC

** Getting onto the web
Create a subdomain on [[http://freedns.afraid.org][freeDNS]].  You may need to click on "/subdomains/" a couple of times.  FreeDNS is preferred because it is one of the few domain name providers which supports genuinely free (as in beer) accounts.  So if your budget is tiny or non-existent you can still participate as a first class citizen of the internet.  If you do have money to spend there is also a premium option.

Select "/dynamic DNS/" then click "/quick cron example/"

An example would look like:

#+BEGIN_SRC: bash
4,9,14,19,24,29,34,39,44,49,54,59 * * * * root sleep 29 ; wget -O - http://free\ dns.afraid.org/dynamic/update.php?ABCKDNRCLFHENSLKNFEGSBFLFF== >> /\ tmp/freedns_mysubdomain_us_to.log 2>&1 &
#+END_SRC

Edit /etc/crontab and append that to the end of the file.

Via your router's firewall settings you should now open port 22 (secure shell).  This will allow you to ssh into your BBB from any location - not just your own local network.

** Install Email

#+BEGIN_VERSE
/If you knew what I know about email, you might not use it/

-- Ladar Levison
#+END_VERSE

Email is not very secure, but its usefulness and ubiquity mean that it's likely to continue as a primary communications method for many years to come.  You can encrypt the contents of email using PGP/GPG, but very few people do that and even for those that do the metadata (the From/To/CC/BCC) is always transmitted in the clear as a fundamental aspect of the protocol, allowing an attacker to easily construct detailed models of people's social network and life patterns even without knowing the content.

Exim4 seems much easier to install and configure than Postfix.

#+BEGIN_SRC: bash
aptitude install exim4 sasl2-bin swaks libnet-ssleay-perl
#+END_SRC

You will be prompted to remove postfix.  Say yes and yes again.

#+BEGIN_SRC: bash
dpkg-reconfigure exim4-config
#+END_SRC

Settings as follows:

#+BEGIN_SRC: bash
internet site

System mail name: mydomainname.com

IP addresses to listen on: blank

Destinations: mydomainname.com

Domains to relay mail: blank

Smarthost Relay: 192.168.1.0/60 (the range of addresses on your LAN)

	#   SSL Engine Options:
	#   Set various options for the SSL engine.
	#   o FakeBasicAuth:
	#     Translate the client X.509 into a Basic Authorisation.  This means that
	#     the standard Auth/DBMAuth methods can be used for access control.  The
	#     user name is the `one line' version of the client's X.509 certificate.
	#     Note that no password is obtained from the user. Every entry in the user
	#     file needs this password: `xxj31ZMTZzkVA'.
	#   o ExportCertData:
	#     This exports two additional environment variables: SSL_CLIENT_CERT and
	#     SSL_SERVER_CERT. These contain the PEM-encoded certificates of the
	#     server (always existing) and the client (only existing when client
	#     authentication is used). This can be used to import the certificates
	#     into CGI scripts.
	#   o StdEnvVars:
	#     This exports the standard SSL/TLS related `SSL_*' environment variables.
	#     Per default this exportation is switched off for performance reasons,
	#     because the extraction step is an expensive operation and is usually
	#     useless for serving static content. So one usually enables the
	#     exportation for CGI and SSI requests only.
	#   o StrictRequire:
	#     This denies access when "SSLRequireSSL" or "SSLRequire" applied even
	#     under a "Satisfy any" situation, i.e. when it applies access is denied
	#     and no other module can change it.
	#   o OptRenegotiate:
	#     This enables optimized SSL connection renegotiation handling when SSL
	#     directives are used in per-directory context.

	#   SSL Protocol Adjustments:
	#   The safe and default but still SSL/TLS standard compliant shutdown
	#   approach is that mod_ssl sends the close notify alert but doesn't wait for
	#   the close notify alert from client. When you need a different shutdown
	#   approach you can use one of the following variables:
	#   o ssl-unclean-shutdown:
	#     This forces an unclean shutdown when the connection is closed, i.e. no
	#     SSL close notify alert is send or allowed to received.  This violates
	#     the SSL/TLS standard but is needed for some brain-dead browsers. Use
	#     this when you receive I/O errors because of the standard approach where
	#     mod_ssl sends the close notify alert.
	#   o ssl-accurate-shutdown:
	#     This forces an accurate shutdown when the connection is closed, i.e. a
	#     SSL close notify alert is send and mod_ssl waits for the close notify
	#     alert of the client. This is 100% SSL/TLS standard compliant, but in
	#     practice often causes hanging connections with brain-dead browsers. Use
	#     this only for browsers where you know that their SSL implementation
	#     works correctly.
	#   Notice: Most problems of broken clients are also related to the HTTP
	#   keep-alive facility, so you usually additionally want to disable
	#   keep-alive for those clients, too. Use variable "nokeepalive" for this.
	#   Similarly, one has to force some clients to use HTTP/1.0 to workaround
	#   their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and
	#   "force-response-1.0" for this.
	BrowserMatch "MSIE [2-6]" \
		nokeepalive ssl-unclean-shutdown \
		downgrade-1.0 force-response-1.0
	# MSIE 7 and newer should be able to use keepalive
	BrowserMatch "MSIE [17-9]" ssl-unclean-shutdown

a2enmod ssl
service apache2 restart
#+END_SRC

Save and exit.

#+BEGIN_SRC: bash
chmod +x makecert
./makecert mydomainname.com
#+END_SRC

Enter some trivial password for the key file.  The password will be removed as part of the makecert script.  Note that leaving a password on the key file would mean that after a power cycle the apache server will not be able to boot properly (it would wait indefinitely for a password to be manually entered) and would look as if it had crashed.

If all has gone well then there should be no warnings or errors after you run the service restart command.  After that you should enable ports 80 (HTTP) and 443 (HTTPS) on your internet router/firewall, such that they are redirected to the BBB.

#+BEGIN_SRC: bash

Finally you can then type *mutt* to get access to your email.  Hence as a fallback, or if you prefer as the primary way of accessing email, you can ssh into the BBB and use the mutt command line email client.  Ssh clients are available for all operating systems, and also you should be reasonably protected from passive surveillance between wherever you are and the BBB (although not between the BBB and the wider internet), which can be useful if you are for example using an Android tablet from a cafe or railway station.

To use the address book system open an email and then to add the sender to the address list press the A key.  It will ask you for an alias which may be used the next time you want to send a mail.  Alternatively you may just edit the *~/.mutt-alias* file directly to add email addresses.

Some useful keys to know are:

| ESC / | Search for text within message contents                 |
| "/"   | Search for text within headers                          |
| *     | Move to the last message                                |
| TAB   | Move to the next unread message                         |

For maximum speed and efficiency the recommended email client is Mutt, accessed via ssh, but non-technical people who aren't using an Android app are unlikely to want to use email in that manner.  So it's a good idea to also have a webmail system installed, both for accessibility and as a fallback should ssh not be available due to port blocking.

Install dependencies.

Now with a browser visit https://mydomainname.com/mail/installer.  Scroll down and click "next".  Give your webmail site a product name.

The *spellcheck_engine* option being limited to Google is slightly concerning in terms of privacy and security, but seems not to be implemented.

Change the *database password* to the password you gave when creating the MySql database above.

Set *smtp_port* to 465.

Click *create config*

Click download to download the file.

In a terminal on your local machine (not logged into the BBB):

#+BEGIN_SRC: bash
cd ~/Downloads
scp config.inc.php myusername@mydomainname.com:/home/myusername
#+END_SRC

Then in a terminal ssh'd into the BBB:

#+BEGIN_SRC: bash

chmod 755 /var/www/$HOSTNAME/htdocs/mail/config/config.inc.php
#+END_SRC

Click *continue*.

Click *initialize database*.

Under *Test SMTP config* you can use a [[mailinator.com]] address to check that mail can be sent.

Now we can delete the installer.

#+BEGIN_SRC: bash

#+END_VERSE

Another common way in which you may want to access email is via Thunderbird.  This may be especially useful if you're trying to convert former Windows users who may previously have been using some version of Outlook.

The following instructions should be carried out on the client machines (laptop, etc), not on the BBB itself.

**** Initial setup

Install *Thunderbird* and *Enigmail*.  How you do this just depends upon your distro and software manager or "app store".

Open Thinderbird

Select "*Skip this and use existing email*"

Enter your name, email address (myusername@mydomainname.com) and the password for your user (the one from [[Add a user]]).

You'll get a message saying "/Thunderbird failed to find the settings/"

The settings should be as follows, substituting /mydomainname.com/ for your domain name and /myusername/ for the username given previously in [[Add a user]].

  * Incoming: IMAP, mydomainname.com, 993, SSL/TLS, Normal Password
  * Outgoing: SMTP, mydomainname.com, 465, SSL/TLS, Normal Password
  * Username: myusername

Click *Done*.

Click *Get Certificate* and make sure "*permanently store this exception*" is selected", then click *Store Security Exception*.

From OpenPGP setup select "*Yes, I would like the wizard to get me started*"

Select "*Yes, I want to sign all of my email*"

Select "*No, I will create per-recipient rules*"

Select "*yes*" to change default settings.

**** If you have existing GPG key

Select "I have existing public and private keys"

Select your public and private GPG exported key files

Select the account which you want to use and click *Next*, *Next* and *Finish*.

**** If you don't have any existing GPG or PGP key
TODO
**** Using for the first time

Click on the Thunderbird menu, which looks like three horizontal bars on the right hand side.

Hover over *preferences* and then *Account settings*.

Select *Synchronization & Storage*.

Make sure that *Keep messages for this account on this computer* is unticked, then click *Ok*.

Click on *Inbox*.  Depending upon how much email you have it may take a while to import the subject lines.

** Install a Blog

Wordpress is the most popular blogging platform, but in practice I found it to be high maintenance with frequent security updates and breakages.  More practical for a home server is Flatpress.  Flatpress doesn't use a MySql database, just text files, and so is easy to relocate or reinstall.

See the [[Setting up a web site]] section of this document for details of how to configure the web server for your blog's domain.

Download flatpress.

#+BEGIN_SRC: bash
cd /tmp
wget http://freedombone.uk.to/flatpress.tar.gz
#+END_SRC

Verify the download:

#+BEGIN_SRC: bash
md5sum flatpress.tar.gz
6ad5c230a5cb1ac096ff657f1b138cc7  flatpress.tar.gz
#+END_SRC

Extract and install it.

#+BEGIN_SRC: bash
tar -xzvf flatpress.tar.gz
cd flatpress-*
cp -r * /var/www/$HOSTNAME/htdocs
rm -rf flatpress-*
rm -f flatpress.tar.gz
#+END_SRC

Now visit your blog and follow the setup instructions, which are quite minimal.  Various themes and addons are available from the Flatpress web site, http://www.flatpress.org

** Install an IRC server

#+BEGIN_VERSE
/Give me the liberty to know, to utter, and to argue freely according to conscience, above all liberties./

-- John Milton
#+END_VERSE

*** Base install

IRC is not an especially secure system.  For instance, even with the best encryption it's easily possible to imagine IRC-specific cribs which could be used by cryptanalytic systems.  However, we'll try to implement it in a manner which will at least give the surveillance aparatus something to ponder over.

First install some dependencies.

#+BEGIN_SRC: bash
apt-get update
apt-get install build-essential openssl libssl-dev
#+END_SRC

Then get the source code for ircd-hybrid.

#+BEGIN_SRC: bash
cd /tmp
mkdir hybrid
cd hybrid
apt-get source ircd-hybrid
#+END_SRC

Modify the source code to include SSL security.

#+BEGIN_SRC: bash
emacs ircd-hybrid-*/debian/rules
#+END_SRC

Beneath MAXCLIENTS add the line:

#+BEGIN_SRC: bash
USE_OPENSSL = 1
#+END_SRC

Then save and exit.  Now we can build the debian package for ircd-hybrid and install it.

#+BEGIN_SRC: bash
cd ircd-hybrid-*
dpkg-buildpackage -rfakeroot -uc -b
cd ..
dpkg -i ircd-hybrid_*.deb
#+END_SRC

Customise the configuration to your system, giving it a name and description.  In this example 192.168.1.60 is the static IP address on the BBB on the local network, so change that if necessary.

#+BEGIN_SRC: bash
emacs /etc/ircd-hybrid/ircd.conf
#+END_SRC

Set *name* to the name of your server, and set a description.

Set a *network_name* and *network_desc*.  The network name should not contain any spaces.

Set max_clients to 20, or however many you expect that you'll typically need.

Within the admin section set your *name* and *email*.

Within the *listen* section set host to your fixed IP address (in the earlier
sections it was 192.168.1.60).

Within the *auth* section set user = "*@192.168.1.60" - or whatever the fixed IP address of the BBB is on your network.

Uncomment the first *connect* section and set the *name* to your domain name, the *host* to 192.168.1.60 and the send/accept passwords to a password which you use to log into the IRC server.  Also set the *port* to 6670.

Save and exit, then restart the IRC server.  Open port 6670 on your internet router and forward it to the BBB.

Ensure that the configuration is only readable by the root user.

#+BEGIN_SRC: bash
chmod 600 /etc/ircd-hybrid/ircd.conf
#+END_SRC

*** Channel management

To to install channel management tools.

#+BEGIN_SRC: bash
cd /tmp
wget http://freedombone.uk.to/hybserv_1.9.4-1_armhf.deb
#+END_SRC

Verify it.

#+BEGIN_SRC: bash
md5sum hybserv_1.9.4-1_armhf.deb
5b66551ceabb679bdeda1859d23ca6ac  hybserv_1.9.4-1_armhf.deb
#+END_SRC

Install it.

#+BEGIN_SRC: bash
dpkg -i hybserv_1.9.4-1_armhf.deb
#+END_SRC

Make a md5 version of the password for the IRC server operator.

#+BEGIN_SRC: bash
/usr/bin/mkpasswd <myoperatorpassword>
#+END_SRC

Edit the ircd-hybrid configuration.

#+BEGIN_SRC: bash
emacs /etc/ircd-hybrid/ircd.conf
#+END_SRC

Enter the md5 password which you previously created within the /operator/ section.  Also change /user/ to:

#+BEGIN_SRC: bash
	user = "*@*";
#+END_SRC

Then save and exit.

#+BEGIN_SRC: bash
emacs /etc/hybserv/hybserv.conf
#+END_SRC

Change #MD5 PASSWORD HERE# to the md5 operator password created earlier, mydomainname.com to your domain name and mysendacceptpassword to the send/accept password specified within /ircd.conf/.

#+BEGIN_SRC: bash
A:mynickname <myemailaddress>
N:irc.mydomainname.com:Hybrid services
O:*@*:#MD5 PASSWORD HERE#:root:segj (comment out other Q: lines)
S:mysendacceptpassword:192.168.1.60:6670 (remove the other two services)
#+END_SRC

Also remove the line *#NOT-EDITED#*, then save and exit.

Now we need to restart the ircd and hybrid server to make things work:

#+BEGIN_SRC: bash
service ircd-hybrid restart
service hybserv start
#+END_SRC

*** Usage

On another computer (not the BBB).

#+BEGIN_SRC: bash
sudo apt-get install irssi
irssi
#+END_SRC

Connect to the IRC and identify yourself as an operator.  Here /mynetwork/ should be the same as *network_name* specified earlier within /ircd.conf/.

#+BEGIN_SRC: bash
/server add -auto -network mynetwork -ssl mydonainname.com 6670 mysendacceptpassword

/connect mydomainname.com

/channel add -auto #mychannel mynetwork channelpassword

/network add -nick mynick mychannel

/join #mychannel

/msg -servername chanserv REGISTER #mychannel channelpassword

/msg -servername chanserv set #mychannel mlock +k channelpassword
#+END_SRC

If you edit the irssi config file:

#+BEGIN_SRC: bash
emacs ~/.irssi/config
#+END_SRC

It should look something like this:

#+BEGIN_SRC: bash
  {
    address = "mydomainname.com";
    chatnet = "mynetwork";
    port = "6670";
    password = "mysendacceptpassword";
    use_ssl = "yes";
    ssl_verify = "no";
    autoconnect = "yes";
  },
#+END_SRC

If you're not using a self-signed certificate (self-signed is the default) then you can set *ssl_verify* to "yes".

** Install a Jabber/XMPP server

#+BEGIN_VERSE
/Well heck, it isn’t that hard to write an instant messaging system./

--Jeremie Miller
#+END_VERSE

*** The Server

Generate a SSL certificate.

#+BEGIN_SRC: bash
openssl ecparam -out /etc/ssl/private/xmpp.pem -name prime256v1
openssl genpkey -paramfile /etc/ssl/private/xmpp.pem -out /etc/ssl/private/xmpp.key
openssl req -new -x509 -key /etc/ssl/private/xmpp.key -out /etc/ssl/certs/xmpp.crt -days 3650
#+END_SRC

The above uses a Diffie-Hellman elliptic curve (ECDH P-256) algorithm.  It is apparent that amongst crypographers there are differences of opinion about the security of elliptic curves, so if you prefer there is also a more traditional RSA way to generate an SSL certificate:

#+BEGIN_SRC: bash
openssl genrsa -out /etc/ssl/private/xmpp.key 4096
openssl req -new -x509 -key /etc/ssl/private/xmpp.key -out /etc/ssl/certs/xmpp.crt -days 3650
#+END_SRC

Change permissions.

#+BEGIN_SRC: bash
chmod 600 /etc/ssl/private/xmpp.key
chmod 600 /etc/ssl/certs/xmpp.crt
chown prosody:prosody /etc/ssl/private/xmpp.key
chown prosody:prosody /etc/ssl/certs/xmpp.crt
#+END_SRC

Install Prosody.

#+BEGIN_SRC: bash
apt-get install prosody
cp -a /etc/prosody/conf.avail/example.com.cfg.lua /etc/prosody/conf.avail/xmpp.cfg.lua
emacs /etc/prosody/conf.avail/xmpp.cfg.lua
#+END_SRC

Change the *VirtualHost* name to your domain name and remove the line below it.

Set the ssl section to:

#+BEGIN_SRC: bash
	ssl = {
		key = "/etc/ssl/private/xmpp.key";
		certificate = "/etc/ssl/certs/xmpp.crt";
		}
#+END_SRC

And also append the following:

#+BEGIN_SRC: bash
modules_enabled = {
  "bosh"; -- Enable mod_bosh
}
#+END_SRC

Save and exit.  Create a symbolic link.

#+BEGIN_SRC: bash
ln -sf /etc/prosody/conf.avail/xmpp.cfg.lua /etc/prosody/conf.d/xmpp.cfg.lua
#+END_SRC

Add a user.  You will be prompted to specify a password.  You can repeat the process for as many users as needed.  This will also be your Jabber ID (JID).

#+BEGIN_SRC: bash
prosodyctl adduser myusername@mydomainname.com
#+END_SRC

Restart the server

#+BEGIN_SRC: bash
service prosody restart
#+END_SRC

On your internet router/firewall open ports 5222, 5223, 5269, 5280 and 5281 and forward them to the BBB.

It's possible to test that your XMPP server is working at https://xmpp.net.  It may take several minutes and you'll get a low score because of the self-signed certificate, but it will at least verify that your server is capable of communicating.

*** Managing users

To add a user:

#+BEGIN_SRC: bash
prosodyctl adduser myusername@mydomainname.com
#+END_SRC

To change a user password:

#+BEGIN_SRC: bash
prosodyctl passwd myusername@mydomainname.com
#+END_SRC

To remove a user:

#+BEGIN_SRC: bash
prosodyctl deluser myusername@mydomainname.com
#+END_SRC

Report the status of the XMPP server:

#+BEGIN_SRC: bash
prosodyctl status
#+END_SRC

*** Using with Jitsi
Jitsi is the recommended communications client for desktop or laptop systems, since it includes the /off the record/ (OTR) feature which provides some additional security beyond the usual SSL certificates.

Jitsi can be downloaded from https://jitsi.org/

On your desktop/laptop open Jitsi and select *Options* from the *Tools* menu.

Click *Add* to add a new user, then enter the Jabber ID which you previously specified with /prosodyctl/ when setting up the XMPP server.  Close and then you should notice that your status is "Online" (or if not then you should be able to set it to online).

From the *File* menu you can add contacts, then select the chat icon to begin a chat.  Click on the lock icon on the right hand side and this will initiate an authentication procedure in which you can specify a question and answer to verify the identity of the person you're communicating with.  Once authentication is complete then you'll be chating using OTR, which provides an additional layer of security.

When opening Jitsi initially you will get a certificate warning for your domain name (assuming that you're using a self-signed certificate). If this happens then select *View Certificate* and enable the checkbox to trust the certificate, then select *Continue Anyway*.  Once you've done this then the certificate warning will not appear again unless you reinstall Jitsi or use a different computer.

You can also [[https://www.youtube.com/watch?v=vgx7VSrDGjk][see this video]] as an example of using OTR.
*** Using with Ubuntu
The default XMPP client in Ubuntu is Empathy.  Using Empathy isn't as secure as using Jitsi, since it doesn't include the /off the record/ feature, but since it's the default it's what many users will have easy access to.

Open *System Settings* and select *Online Accounts*, *Add account*  and then *Jabber*.

Enter your username (myusername@mydomainname.com) and password.

Click on *Advanced* and make sure that *Encryption required* and *Ignore SSL certificate errors* are checked.  Ignoring the certificate errors will allow you to use the self-signed certificate created earlier.  Then click *Done* and set your Jabber account and Empathy to *On*.
*** Using with Android

There are a few XMPP clients available on Android.  Ideally choose ones which support off-the-record messaging.  Here are some examples.

**** Xabber
Install [[https://f-droid.org/][F-Droid]]

Search for and install Xabber.

Add an account and enter your Jabber/XMPP ID and password.

From the menu select *Settings* then *Security* then *OTR mode*.  Set the mode to *Required*.

Make sure that *Check server certificate* is not checked.

Go back to the initial screen and then using the menu you can add contacts and begin chatting.  Both parties will need to go through the off-the-record question and answer verification before the chat can begin, but that only needs to be done once for each person you're chatting with.

**** Gibberbot
Install [[https://f-droid.org/][F-Droid]]

Search for and install Gibberbot, otherwise known as ChatSecure.

From the menu open *Accounts*

Select *Add account*

Change the server port from 0 to 5222

Done

Accept unknown certificate? Select *Always*

Go back to the initial screen and then using the menu you can add contacts and begin chatting.

** Social Networking

*** Friendica
**** Installation

See [[Setting up a web site]] for details of how to update the Apache configuration for your Friendica site.  You should have a separate domain name specifically to run Friendica on.  It can't be installed in a subdirectory on a domain used for something else.

Edit your Apache configuration and disable the port 80 (HTTP) version of the site.  We only want to log into Friendica via HTTPS, so to prevent anyone from accidentally logging in insecurely:

#+BEGIN_SRC: bash
emacs /etc/apache2/sites-available/mydomainname.com
#+END_SRC

Within the section which begins with *<VirtualHost *:80>* change the following:

#+BEGIN_SRC: bash
  <Directory /var/www/mydomainname.com/htdocs/>
    deny from all
  </Directory>
#+END_SRC

Save and exit, then restart the apache server.

#+BEGIN_SRC: bash
service apache2 restart
#+END_SRC

Now install some dependencies.

#+BEGIN_SRC: bash
apt-get install mysql-server php5-common php5-cli php5-curl php5-gd php5-mysql php5-mcrypt
#+END_SRC

Enter an admin password for MySQL.

Create a mysql database.

#+BEGIN_SRC: bash
mysql -u root -p
create database friendica;
CREATE USER 'friendicaadmin'@'localhost' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON friendica.* TO 'friendicaadmin'@'localhost';
quit
#+END_SRC

You may need to fix Git SSL problems.

#+BEGIN_SRC: bash
git config --global http.sslVerify true
apt-get install ca-certificates
cd ~/
emacs .gitconfig
#+END_SRC

The .gitconfig file should look something like this:

#+BEGIN_SRC: bash
[http]
        sslVerify = true
        sslCAinfo = /etc/ssl/certs/ca-certificates.crt
[user]
        email = myusername@mydomainname.com
        name = yourname
#+END_SRC

Get the source code.

#+BEGIN_SRC: bash
export HOSTNAME=mydomainname.com
cd /var/www/$HOSTNAME
mv htdocs htdocs_old
git clone https://github.com/friendica/friendica.git htdocs
chmod -R 755 htdocs
chown -R www-data:www-data htdocs
chown -R www-data:www-data htdocs/view/smarty3
git clone https://github.com/friendica/friendica-addons.git htdocs/addon
#+END_SRC

Now visit the URL of your site and you should be taken through the rest of the installation procedure.  If you have trouble with "allow override" ensure that "AllowOverride" is set to "all" in your Apache settings for the site (within /etc/apache2/sites-available) and then restart the apache2 service.

Install the poller.

#+BEGIN_SRC: bash
emacs /etc/crontab
#+END_SRC

and append the following, changing mydomainname.com to whatever your domain is.

#+BEGIN_SRC: bash
*/10 *  * * *	root	cd /var/www/mydomainname.com/htdocs; /usr/bin/php include/poller.php
#+END_SRC

Save and exit, then restart cron.

#+BEGIN_SRC: bash
service cron restart
#+END_SRC

You can improve the speed of Friendica database searches by adding the following indexes:

#+BEGIN_SRC: bash
mysql -u root -p
use friendica;
CREATE INDEX `uri_received` ON item(`uri`, `received`);
CREATE INDEX `received_uri` ON item(`received`, `uri`);
CREATE INDEX `contact-id_created` ON item(`contact-id`, created);
CREATE INDEX `uid_network_received` ON item(`uid`, `network`, `received`);
CREATE INDEX `uid_parent` ON item(`uid`, `parent`);
CREATE INDEX `uid_received` ON item(`uid`, `received`);
CREATE INDEX `uid_network_commented` ON item(`uid`, `network`, `commented`);
CREATE INDEX `uid_title` ON item(uid, `title`);
CREATE INDEX `created_contact-id` ON item(`created`, `contact-id`);
quit
#+END_SRC

Make sure that Friendica doesn't use too much memory.

#+BEGIN_SRC: bash
emacs /var/www/$HOSTNAME/htdocs/.htaccess
#+END_SRC

Append the following:

#+BEGIN_SRC: bash
php_value memory_limit 32M
#+END_SRC

The save ane exit.

**** Backups

Make sure that the database gets backed up.  By using cron if anything goes wrong then you should be able to recover the database either from the previous day or the previous week.

#+BEGIN_SRC: bash
emacs /etc/cron.daily/friendicabackup
#+END_SRC

Enter the following

#+BEGIN_SRC: bash
#!/bin/sh

MYSQL_PASSWORD=<mysql root password>

umask 0077

# Backup the database
mysqldump --password=$MYSQL_PASSWORD friendica > /var/backups/friendica_daily.sql

# Make the backup readable only by root
chmod 600 /var/backups/friendica_daily.sql
#+END_SRC

Save and exit.

#+BEGIN_SRC: bash
chmod 600 /etc/cron.daily/friendicabackup
chmod +x /etc/cron.daily/friendicabackup
emacs /etc/cron.weekly/friendicabackup
#+END_SRC

Enter the following

#+BEGIN_SRC: bash
#!/bin/sh

MYSQL_PASSWORD=<mysql root password>

umask 0077

# Backup the database
mysqldump --password=$MYSQL_PASSWORD friendica > /var/backups/friendica_weekly.sql

# Make the backup readable only by root
chmod 600 /var/backups/friendica_weekly.sql
#+END_SRC

Save and exit.

#+BEGIN_SRC: bash
chmod 600 /etc/cron.weekly/friendicabackup
chmod +x /etc/cron.weekly/friendicabackup
#+END_SRC

**** Recommended configuration
***** Admin
To get to the admin settings you will need to be logged in with the admin email address which you specified at the beginning of the installation procedure.  Depending upon the theme which you're using "/admin/" will be available either as an icon or on a drop down menu.

Under the *plugins* section the main one which you may wish to enable is the NSFW plugin.  With that enabled if a post contans the #NSFW tag then it will appear minimised by default and you will need to click a button to open it.

Under the *themes* section select a few themes, including mobile themes which are suitable for phones or tablets.

Under the *site* section give your Friendica node a name other than "/my friend network/", you can change the icon and banner text and set the default mobile theme typically to /frost-mobile/.  If you don't want your node to host a lot of accounts for people you don't know then you may want to set the register policy to "/requires approval/".  For security it's probably a good idea only to host accounts for people who you actually know, rather than random strangers.  Also be aware that the Beaglebone does not have a great deal of computational power or bandwidth and will not function well if there are hundreds of users using your node.  If you're not federating with Diaspora or other sites then you may wish to select "/only allow Friendica contacts/".  That improves the security of the system, since communication between Friendica nodes is always encrypted separately and in addition to the usual SSL encryption layer - which makes life interesting for the Surveillance State and at least keeps those cryptanalysts employed.

It's probably a good idea to enable "/private posts by default for new users/" and also "/don't include post content in email notifications/".  Since traditional email isn't a secure system and is easily vulnerable to attack by systems such as [[https://en.wikipedia.org/wiki/XKeyscore][Xkeyscore]].

***** Settings
Each user has their own customisable settings, typically available either via an icon or by an entry on a drop down menu.

Under *additional features* enable "/richtext editor/", "/post preview/", "/group filter/", "/network filter/", "/edit sent posts/" and "/dislike posts/".

Under *display settings* select your desktop and mobile themes.

Once you have connected to enough friends it's also a good idea to use the "/export personal data/" option from here.  This will save a file to your local system, which you can import into another friendica node if necessary.
**** To access from an Android device
***** App
Open a browser on your device and go to https://f-droid.org/ then download and install the F-Droid apk.  If you then open F-Droid you can search for and install the Friendica app.

If you are using a self-signed certificate then at the login screen scroll down to the bottom, select the SSL settings then scroll down and disable SSL certificate checks.  You will then be able to log in using https, which at least gives you some protection via the encryption.

More information about the Friendica app can be found on http://friendica-for-android.wiki-lab.net/
***** Mobile Theme
Another way to access Friendica from a mobile device is to just use the web browser.  If you have selected a mobile theme within your settings then when viewing from an Android system the mobile theme will be displayed.

#+END_VERSE

Movim is another social networking system based around the XMPP protocol.

You will need to have previously [[Install a Jabber/XMPP server][installed the Jabber/XMPP server]].

Edit your Apache configuration and disable the port 80 (HTTP) version of the site.  We only want to log into Movim via HTTPS, so to prevent anyone from accidentally logging in insecurely:

#+BEGIN_SRC: bash
emacs /etc/apache2/sites-available/mydomainname.com

Within the section which begins with *<VirtualHost *:80>* add the following:

#+BEGIN_SRC: bash
  <Directory /var/www/mydomainname.com/htdocs/movim>
    deny from all
  </Directory>
#+END_SRC

Within the section which begins with *<VirtualHost *:443>* add the following:

#+BEGIN_SRC: bash
  <Directory /var/www/mydomainname.com/htdocs/movim>
    Options Indexes FollowSymLinks MultiViews
    AllowOverride All
    Order allow,deny
    allow from all

#+END_SRC

Save and exit, then restart the apache server.

#+BEGIN_SRC: bash
service apache2 restart
#+END_SRC

Download the source.

#+BEGIN_SRC: bash
cd /tmp

export HOSTNAME=mydomainname.com
cp -r movim-* /var/www/$HOSTNAME/htdocs/movim
chmod 755 /var/www/$HOSTNAME/htdocs/movim
chown -R www-data:www-data /var/www/$HOSTNAME/htdocs/movim
#+END_SRC

Install some MySql prerequisites.

#+BEGIN_SRC: bash
apt-get install mysql-server php5-common php5-cli php5-curl php5-gd php5-mysql php5-mcrypt
#+END_SRC

If necessary, enter an admin password for MySQL.

Create a mysql database.

#+BEGIN_SRC: bash
mysql -u root -p
create database movim;
CREATE USER 'movimadmin'@'localhost' IDENTIFIED BY 'movimadminpassword';
GRANT ALL PRIVILEGES ON movim.* TO 'movimadmin'@'localhost';
quit
#+END_SRC

With a web browser navigate to:

https://mydomainname.com/movim/admin

Enter /admin/ as the username and /password/ as the password.

Click on /General Settings/ and alter the administrator username to /movimadmin/ and password to some long random string (using a password manager such as KeepassX).

Change the /Environment/ from /Development/ to /Production/.

The /BOSH URL/ should be http://localhost:5280/http-bind (TODO: should this be https://localhost:5281/http-bind and if so do certificate warnings need to be disabled?)

Click /Submit/ followed by /Resend/.

Click on /Database Settings/ and alter the MySql movim database username to /movimadmin/ and password to the password you specified in the previous step.

Click /Submit/ followed by /Resend/.  If you get a lot of orange warnings about database fields being created then hit /Submit/ again until you see "Movim database is up to date".

If everything on all three tabs looks green then you are ready to go.  Click on the Movim logo at the top left and then log in with your Jabber ID (JID).

Red Matrix is the current version of the Friendica social networking system.  It's more general than Friendica in that it's designed as a generic communication system based around a protocol called "zot".  At the time of writing in early 2014 Red Matrix remains at an alpha stage of development and so it's not advised that you install it unless you're willing to put up with bugs and frustrations.  In the large majority of cases it's better to stick with Friendica for now.

**** Prerequisites
The main problem with Red Matrix is that in order to install it you will need to have purchased a domain name (i.e. not a FreeDNS subdomain) and a SSL certificate for it.

You could join some other Red Matrix server, but this suffers from "/The Levison Problem/" in which some goons show up with a gagging order demanding coppies of the SSL private key.  In that scenario unless the owner of the server is exceptionally brave users may never be informed that the site has been compromised or that there is interception hardware attached to the server.  Joining another server defeats the object of being digitally self-sufficient and raises legal question marks about the ownership of data which you might upload to a server which doesn't belong to you.

**** Installation

See [[Setting up a web site]] for details of how to update the Apache configuration for your Red Matrix site.  You should have a separate domain name specifically to run Red Matrix on.  It can't be installed in a subdirectory on a domain used for something else.

Edit your Apache configuration and disable the port 80 (HTTP) version of the site.  We only want to log into Red Matrix via HTTPS, so to prevent anyone from accidentally logging in insecurely:

#+BEGIN_SRC: bash
emacs /etc/apache2/sites-available/mydomainname.com
#+END_SRC

Within the section which begins with *<VirtualHost *:80>* change the following:

#+BEGIN_SRC: bash
  <Directory /var/www/mydomainname.com/htdocs/>
    deny from all
  </Directory>
#+END_SRC

Save and exit, then restart the apache server.

#+BEGIN_SRC: bash
service apache2 restart
#+END_SRC

Now install some dependencies.

#+BEGIN_SRC: bash
apt-get install mysql-server php5-common php5-cli php5-curl php5-gd php5-mysql php5-mcrypt
#+END_SRC

Enter an admin password for MySQL.

Create a mysql database.

#+BEGIN_SRC: bash
mysql -u root -p
create database redmatrix;
CREATE USER 'redmatrixadmin'@'localhost' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON redmatrix.* TO 'redmatrixadmin'@'localhost';
quit
#+END_SRC

You may need to fix Git SSL problems.

#+BEGIN_SRC: bash
git config --global http.sslVerify true
apt-get install ca-certificates
cd ~/
emacs .gitconfig
#+END_SRC

The .gitconfig file should look something like this:

#+BEGIN_SRC: bash
[http]
        sslVerify = true
        sslCAinfo = /etc/ssl/certs/ca-certificates.crt
[user]
        email = myusername@mydomainname.com
        name = yourname
#+END_SRC

Get the source code.

#+BEGIN_SRC: bash
export HOSTNAME=mydomainname.com
cd /var/www/$HOSTNAME
mv htdocs htdocs_old
git clone https://github.com/friendica/red.git htdocs
chmod -R 755 htdocs
chown -R www-data:www-data htdocs
mkdir htdocs/view/tpl/smarty3
chmod 777 htdocs/view/tpl
chmod 777 htdocs/view/tpl/smarty3
git clone https://github.com/friendica/red-addons.git htdocs/addon
#+END_SRC

Now visit the URL of your site and you should be taken through the rest of the installation procedure.  Note that this may take a few minutes so don't be concerned if it looks as if it has crashed - just leave it running.  If you have trouble with "allow override" ensure that "AllowOverride" is set to "all" in your Apache settings for the site (within /etc/apache2/sites-available) and then restart the apache2 service.

Install the poller.

#+BEGIN_SRC
emacs /etc/crontab
#+END_SRC

and append the following, changing mydomainname.com to whatever your domain is.

#+BEGIN_SRC
*/10 *  * * *	root	cd /var/www/mydomainname.com/htdocs; /usr/bin/php include/poller.php
#+END_SRC

Save and exit, then restart cron.

#+BEGIN_SRC: bash
service cron restart
#+END_SRC

**** Backups

Make sure that the database gets backed up.  By using cron if anything goes wrong then you should be able to recover the database either from the previous day or the previous week.

#+BEGIN_SRC: bash
emacs /etc/cron.daily/redmatrixbackup
#+END_SRC

Enter the following

#+BEGIN_SRC: bash
#!/bin/sh

MYSQL_PASSWORD=<mysql root password>

umask 0077

# Backup the database
mysqldump --password=$MYSQL_PASSWORD redmatrix > /var/backups/redmatrix_daily.sql

# Make the backup readable only by root
chmod 600 /var/backups/redmatrix_daily.sql
#+END_SRC

Save and exit.

#+BEGIN_SRC: bash
chmod 600 /etc/cron.daily/redmatrixbackup
chmod +x /etc/cron.daily/redmatrixbackup
emacs /etc/cron.weekly/redmatrixbackup
#+END_SRC

Enter the following

#+BEGIN_SRC: bash
#!/bin/sh

MYSQL_PASSWORD=<mysql root password>

umask 0077

# Backup the database
mysqldump --password=$MYSQL_PASSWORD redmatrix > /var/backups/redmatrix_weekly.sql

# Make the backup readable only by root
chmod 600 /var/backups/redmatrix_weekly.sql
#+END_SRC

Save and exit.

#+BEGIN_SRC: bash
chmod 600 /etc/cron.weekly/redmatrixbackup
chmod +x /etc/cron.weekly/redmatrixbackup
#+END_SRC
**** To access from an Android device
***** App
Open a browser on your device and go to https://f-droid.org/ then download and install the F-Droid apk.  If you then open F-Droid you can search for and install the Friendica app.

If you are using a self-signed certificate then at the login screen scroll down to the bottom, select the SSL settings then scroll down and disable SSL certificate checks.  You will then be able to log in using https, which at least gives you some protection via the encryption.

More information about the Friendica app can be found on http://friendica-for-android.wiki-lab.net/

** Install Gopher
Gopher is an old internet protocol which originated a few years before the web and is purely text based.  It can be quite fun to build a gopher site and browse the gopherverse.  One thing to keep in mind is that there is no security with gopher, so any text transmitted is trivially interceptable by systems such as [[https://en.wikipedia.org/wiki/XKeyscore][Xkeyscore]] or deep packet inspection.

To set up a gopher server:

#+BEGIN_SRC: bash
apt-get install build-essential
cd /tmp
wget http://freedombone.uk.to/geomyidae-current.tgz
#+END_SRC

Verify the download:

#+BEGIN_SRC: bash
md5sum geomyidae-current.tgz
3d8bb8601f37ca953b00fc2445ab5abe  geomyidae-current.tgz
#+END_SRC

Then extract and install it.

#+BEGIN_SRC: bash
tar -xzvf geomyidae-current.tgz
cd geomyidae-*
make
make install
mkdir -p /var/gopher
#+END_SRC

Your content should be placed within /var/gopher with the index page being named index.gph.  The Gopher format is very simple - simpler than HTML - so creating pages is not much more difficult than editing a text file.

#+BEGIN_SRC: bash
emacs /etc/init.d/gopher
#+END_SRC

Enter the following:

#+BEGIN_SRC: bash
#! /bin/sh

#+END_SRC

Save and exit.  Then start the gopher service.

#+BEGIN_SRC: bash
chmod +x /etc/init.d/gopher
update-rc.d gopher defaults
service gopher start
#+END_SRC

On your internet router change the firewall settings to route port 70 to the BBB, then provided that you have a gopher plugin installed within your browser then you should be able to navigate to your gopher site with:

#+BEGIN_SRC: bash
gopher://mydomainname.com
#+END_SRC

There is a browser addon for Gopher called "overbite".  Installing that should enable you to view your site.

** Install Owncloud

#+BEGIN_VERSE
/It's not water vapour/

-- Larry Ellison
#+END_VERSE

Owncloud will allow you to upload and download files, share photos, collaboratively edit documents, have a calendar and more.  You should be warned that Owncloud runs quite slowly via an ordinary web browser, but it can be a convenient way to access and share your data from any location in a reasonably secure manner.

*** Server Installation

Install some dependencies:

#+BEGIN_SRC: bash
apt-get install apache2 php5 php5-gd php-xml-parser php5-intl
apt-get install php5-sqlite php5-mysql smbclient curl libcurl3 php5-curl
#+END_SRC

It's very important that /mod_php5/ and not /mod_php5filter/ be installed.  If you have /mod_php5filter/ installed then Owncloud will always fail to install.

#+BEGIN_SRC: bash
a2dismod php5filter
apt-get install libapache2-mod-php5
#+END_SRC

Ensure that the size of files which may be uploaded or downloaded is large enough.

#+BEGIN_SRC: bash
emacs /etc/php5/apache2/php.ini
#+END_SRC

Set the following:

#+BEGIN_SRC: bash
upload_max_filesize = 512M
post_max_size = 512M
#+END_SRC

Save and exit, then edit your Apache configuration.

#+BEGIN_SRC: bash
export HOSTNAME=mydomainname.com
emacs /etc/apache2/sites-available/$HOSTNAME
#+END_SRC

And add the following, to the 443 VirtualHost section.  Really we only will want to be using Owncloud with HTTPS to ensure some level of security and avoidance of dragnet surveillance.

#+BEGIN_SRC: bash
  <Directory /var/www/mydomainname.com/htdocs/owncloud>
    Options Indexes FollowSymLinks MultiViews
    AllowOverride All
    Order allow,deny
    allow from all
  </Directory>
#+END_SRC

To ensure that nobody logs in insecurely add the following to the 80 VirtualHost section.

#+BEGIN_SRC: bash
  <Directory /var/www/mydomainname.com/htdocs/owncloud>
    deny from all
  </Directory>
#+END_SRC

Save and exit, then restart apache.

#+BEGIN_SRC: bash
service apache2 restart
#+END_SRC

Download owncloud.

#+BEGIN_SRC: bash
cd /tmp
wget http://freedombone.uk.to/owncloud.tar.bz2
#+END_SRC

Verify the download:

#+BEGIN_SRC: bash
md5sum owncloud.tar.bz2
f43eabb746b5e339ee70d0a6aaf4a49c
#+END_SRC

Extract the archive.  This may take a couple of minutes, so don't be alarmed that the system has crashed.

#+BEGIN_SRC: bash
export HOSTNAME=mydomainname.com
tar -xjf owncloud.tar.bz2
#+END_SRC

Move the extracted files to your site and set file permissions.

#+BEGIN_SRC: bash
cp -r owncloud /var/www/$HOSTNAME/htdocs
chown -R www-data:www-data /var/www/$HOSTNAME/htdocs/owncloud/apps
chown -R www-data:www-data /var/www/$HOSTNAME/htdocs/owncloud/config
chown www-data:www-data /var/www/$HOSTNAME/htdocs/owncloud
#+END_SRC

Edit the htaccess file for Owncloud.

#+BEGIN_SRC: bash
emacs /var/www/$HOSTNAME/htdocs/owncloud/.htaccess
#+END_SRC

Set the following.

#+BEGIN_SRC: bash
php_value upload_max_filesize 512M
php_value post_max_size 512M
php_value memory_limit 32M
#+END_SRC

Save and exit.

With a web browser visit your domain (mydomainname.com/owncloud) and enter an administrator username and password.

*** Owncloud on Android

First install [[https://f-droid.org/][F-Droid]] and then search for the current Owncloud app.  Once it's installed you'll then be able to log into the BBB with the URL https://mydomainname.com/opencloud, supplying your username and password.

** Install a Wiki

#+BEGIN_VERSE
/I believe that technology can liberate, but you need to be a master rather than a user. You need to pull technology apart and master it rather than letting it control you./

-- Tom Barbalet
#+END_VERSE

Dokuwiki is based upon flat files, and so is easy to move from one server to another without a lot of database complications.

Download the wiki.

#+BEGIN_SRC: bash
cd /tmp
wget http://freedombone.uk.to/dokuwiki.tgz
#+END_SRC

Verify it.

#+BEGIN_SRC: bash
md5sum dokuwiki.tgz
9f35055848429659fd63cda1cfea5a48  dokuwiki.tgz
#+END_SRC

Then extract and install it.

#+BEGIN_SRC: bash
export HOSTNAME=mywikidomainname.com
tar -xzvf dokuwiki.tgz
mv /var/www/$HOSTNAME/htdocs /var/www/$HOSTNAME/htdocs_old
mv dokuwiki /var/www/$HOSTNAME/htdocs
#+END_SRC

Edit the Apache configuration for your wiki site.

#+BEGIN_SRC: bash
emacs /etc/apache2/sites-available/$HOSTNAME
#+END_SRC

The settings should look something like the following.  Replace /mywikidomainname.com/ with your wiki domain name.

#+BEGIN_SRC: bash

	#   SSL Engine Options:
	#   Set various options for the SSL engine.
	#   o FakeBasicAuth:
	#     Translate the client X.509 into a Basic Authorisation.  This means that
	#     the standard Auth/DBMAuth methods can be used for access control.  The
	#     user name is the `one line' version of the client's X.509 certificate.
	#     Note that no password is obtained from the user. Every entry in the user
	#     file needs this password: `xxj31ZMTZzkVA'.
	#   o ExportCertData:
	#     This exports two additional environment variables: SSL_CLIENT_CERT and
	#     SSL_SERVER_CERT. These contain the PEM-encoded certificates of the
	#     server (always existing) and the client (only existing when client
	#     authentication is used). This can be used to import the certificates
	#     into CGI scripts.
	#   o StdEnvVars:
	#     This exports the standard SSL/TLS related `SSL_*' environment variables.
	#     Per default this exportation is switched off for performance reasons,
	#     because the extraction step is an expensive operation and is usually
	#     useless for serving static content. So one usually enables the
	#     exportation for CGI and SSI requests only.
	#   o StrictRequire:
	#     This denies access when "SSLRequireSSL" or "SSLRequire" applied even
	#     under a "Satisfy any" situation, i.e. when it applies access is denied
	#     and no other module can change it.
	#   o OptRenegotiate:
	#     This enables optimized SSL connection renegotiation handling when SSL
	#     directives are used in per-directory context.
	#SSLOptions +FakeBasicAuth +ExportCertData +StrictRequire
	<FilesMatch "\.(cgi|shtml|phtml|php)$">

	</Directory>

	#   SSL Protocol Adjustments:
	#   The safe and default but still SSL/TLS standard compliant shutdown
	#   approach is that mod_ssl sends the close notify alert but doesn't wait for
	#   the close notify alert from client. When you need a different shutdown
	#   approach you can use one of the following variables:
	#   o ssl-unclean-shutdown:
	#     This forces an unclean shutdown when the connection is closed, i.e. no
	#     SSL close notify alert is send or allowed to received.  This violates
	#     the SSL/TLS standard but is needed for some brain-dead browsers. Use
	#     this when you receive I/O errors because of the standard approach where
	#     mod_ssl sends the close notify alert.
	#   o ssl-accurate-shutdown:
	#     This forces an accurate shutdown when the connection is closed, i.e. a
	#     SSL close notify alert is send and mod_ssl waits for the close notify
	#     alert of the client. This is 100% SSL/TLS standard compliant, but in
	#     practice often causes hanging connections with brain-dead browsers. Use
	#     this only for browsers where you know that their SSL implementation
	#     works correctly.
	#   Notice: Most problems of broken clients are also related to the HTTP
	#   keep-alive facility, so you usually additionally want to disable
	#   keep-alive for those clients, too. Use variable "nokeepalive" for this.
	#   Similarly, one has to force some clients to use HTTP/1.0 to workaround
	#   their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and
	#   "force-response-1.0" for this.
	BrowserMatch "MSIE [2-6]" \
		nokeepalive ssl-unclean-shutdown \
		downgrade-1.0 force-response-1.0
	# MSIE 7 and newer should be able to use keepalive
	BrowserMatch "MSIE [17-9]" ssl-unclean-shutdown

Open a browser and visit http://$HOSTNAME/install.php, then fill out the details.  Once everything has been accepted without errors:

#+BEGIN_SRC: bash
rm /var/www/$HOSTNAME/htdocs/install.php
#+END_SRC

Add a few extra mime types:

#+BEGIN_SRC: bash
emacs /var/www/$HOSTNAME/htdocs/conf/mime.conf
#+END_SRC

Append the following:

#+BEGIN_SRC: bash
ogv     video/ogg

** Install Bitmessage

#+BEGIN_VERSE
/Love your neighbour. Fight the future. If you are reading this you ARE the resistance./

-- BitChirp
#+END_VERSE

*** A new kind of Email
[[https://bitmessage.org][Bitmessage]] is a new type of messaging system intended to fulfill the same role as email, but without the security problems.  In particular, Bitmessage attempts to not just encrypt the content but also the metadata.  It's message broadcasting system makes it exceedingly difficult for an attacker to know which computer a message is destined for.  The only way you know whether a message has been sent to you is whether you are able to decrypt it from the passing stream of messages.

Although similar to Bitcoin in some regards, such as "/proof of work/", Bitmessage has no block chain and messages are only buffered for approximately three days after which they are deleted from any given node.

Installing Bitmessage as a daemon will increase the size of the network, and therefore the level of security for all users.

*** The Daemon

Install from the current source code.

#+BEGIN_SRC: bash
apt-get install python screen
cd /tmp
git clone https://github.com/Bitmessage/PyBitmessage.git
cd PyBitmessage
make install
#+END_SRC

Now create the daemon.

#+BEGIN_SRC: bash
emacs /etc/init.d/pybitmessage
#+END_SRC

Add the following text:

#+BEGIN_SRC: bash
#!/bin/bash
# /etc/init.d/bitmessage

### BEGIN INIT INFO

    bm_stop
    ;;

    bm_stop
    sleep 60s
    bm_start
    ;;
    *)
  echo "Usage: $0 {start|stop|restart}"
  exit 1
  ;;
esac

exit 0
#+END_SRC

Save and exit.

Add a user which will be specifically for Bitmessage.  Since bitmessage is still a relatively young and experimental project, this adds further compartmentalisation such that if there are any bugs within PyBitmessage then an attacker can't neccessarily gain control of root or any other user account.  Here we create a user called /bitmsg/ and give it a long random password.

#+BEGIN_SRC: bash
adduser bitmsg
#+END_SRC

Create a /keys.dat/ file which is used to configure Bitmessage.

#+BEGIN_SRC: bash
mkdir /home/bitmsg/.config
mkdir /home/bitmsg/.config/PyBitmessage
emacs /home/bitmsg/.config/PyBitmessage/keys.dat
#+END_SRC

Add the following:

#+BEGIN_SRC: bash
[bitmessagesettings]
settingsversion = 7
port = 8444
timeformat = %%a, %%d %%b %%Y  %%I:%%M %%p
blackwhitelist = black
startonlogon = false
minimizetotray = false
showtraynotifications = false
startintray = false
socksproxytype = none
sockshostname = localhost
socksport = 9050
socksauthentication = false
sockslisten = false
socksusername =
sockspassword =
keysencrypted = false
messagesencrypted = false
defaultnoncetrialsperbyte = 640
defaultpayloadlengthextrabytes = 14000
minimizeonclose = false
maxacceptablenoncetrialsperbyte = 0
maxacceptablepayloadlengthextrabytes = 0
userlocale = system
namecoinrpctype = namecoind
namecoinrpchost = localhost
namecoinrpcuser =
namecoinrpcpassword =
namecoinrpcport = 8336
sendoutgoingconnections = True
daemon = true
#+END_SRC

Save and exit. Then enable the daemon and run it.

#+BEGIN_SRC: bash
rm -f /tmp/-usr-local-share-pybitmessage-*.lock
chown -R bitmsg:bitmsg /home/bitmsg
chmod +x /etc/init.d/pybitmessage
update-rc.d pybitmessage defaults
service pybitmessage start
#+END_SRC

Now open port 8444 on your internet router or firewall and direct it to the BBB.

*** Using Bitmessage
Although in principle it would be possible to send Bitmessages directly from the BBB, in practice the /proof of work/ requirement would mean that it would take an infeasibly long time to send messages, and the computational workload would likely greatly impair the performance of other services also running on the system.  So to send and receive Bitmessages it's better to just install the client on a laptop or desktop machine.

The easiest way to install the client is either to download it from [[https://bitmessage.org][bitmessage.org]] or to get the latest build from Github as follows:

#+BEGIN_SRC: bash
cd /tmp
git clone https://github.com/Bitmessage/PyBitmessage.git
cd PyBitmessage
make install
pybitmessage
#+END_SRC

** Install Tripwire

#+BEGIN_VERSE
/...by the time you get done with all of that, we have a freedom box/

-- Eben Moglen
#+END_VERSE

Tripwire will try to detect any intrusions into your system. It's a good idea to install it after you have installed all of the other programs which you intend to use.

#+BEGIN_SRC: bash
apt-get install tripwire
export HOSTNAME=mydomainname.com
cd /etc/tripwire
cp arm-local.key $HOSTNAME-local.key
cp site.key $HOSTNAME-site.key
tripwire --init
tripwire --update-policy --secure-mode low /etc/tripwire/twpol.txt
tripwire --check --interactive
#+END_SRC

you will be asked for two passphrases ("site" and "local").  Make a note of these.

Turn off reporting of changes to system logs.

#+BEGIN_SRC: bash
emacs /etc/tripwire/twcfg.txt
#+END_SRC

Set *SYSLOGREPORTING* to false, then save and exit.

If you subsequently install any more packages or make configuration changes then update the policy again with:

#+BEGIN_SRC: bash
tripwire --update-policy --secure-mode low /etc/tripwire/twpol.txt
#+END_SRC

Also, to look for any rootkits.

#+BEGIN_SRC: bash
apt-get install rkhunter
#+END_SRC

* Router/Firewall ports
The following ports on your internet router/firewall should be forwarded to the BBB.

| Protocol      |     Port/s |
|---------------+------------|
| Gopher        |         70 |
| HTTP          |         80 |
| HTTPS         |        443 |
| IMAP          |        143 |
| IRC SSL       |       6670 |
| SIP           | 5060..5061 |
| SMTP          |         25 |
| SMTPS         |        465 |
| SSH           |         22 |
| XMPP          | 5222..5223 |
| XMPP (server) |       5269 |
| XMPP (BOSH)   | 5280..5281 |
| Bitmessage    |       8444 |

* Hints and Tips
** Messaging security
If you're connected to other friends via Friendica then the preferred way to send private messages is via Friendica's built-in messaging system.  This is a lot more convenient than using GPG with ordinary email and yet still provides a similar level of protection from unwarranted interception.
** Restrictive/hostile user environments
If you are typically operating within a restrictive of hostile environment where using ssh is not an option because everything other than web ports are blocked then you may wish to try installing oterm:

http://www.coralbits.com/oterm/

https://github.com/davidmoreno/onion
** Moving Domains
If you're moving servers and using a different domain name or path then you can search and replace URLs within files in the following way:

#+BEGIN_SRC: bash
find /var/www/mynewdomain/htdocs -type f -exec sed -i 's@myolddomain@mynewdomain@g' {} \;
#+END_SRC

** MySql foo
*** Backup all databases
To back up all mysql databases:

#+BEGIN_SRC: bash
mysqldump -u root -p --all-databases --events > /var/backups/databasebackup.sql
#+END_SRC
*** Restoring a particular mysql database
To restore yesterday's friendica backup:

#+BEGIN_SRC: bash
mysql -D friendica -o < /var/backups/friendica_daily.sql
#+END_SRC

To restore yesterday's mediawiki backup:

#+BEGIN_SRC: bash
mysql -D wikidb -o < /var/backups/wikidb_daily.sql
#+END_SRC
*** Removing mysql server

If you manage to screw up sql server completely then it can be fully deleted with:

#+BEGIN_SRC: bash
ps aux | grep mysql
#+END_SRC

and use /kill -9 <pid>/ to kill all mysql processes.

#+BEGIN_SRC: bash
apt-get remove --purge mysql\*
apt-get clean
updatedb
#+END_SRC
* Deprecated

The following items have been deprecated until such time as a successful installation is achieved.

** Install a VoIP server

#+BEGIN_VERSE
/Our core principles, whether in software or sovereignty, have always been about freedom and dignity, for all people, on an equal basis/

-- David Sugar, GNU Telephony
#+END_VERSE

*** The server
Sipwitch is like an introduction service or phone book for SIP VoIP clients.  Once introduced the clients can then talk directly, and this means that sipwitch is very lightweight and can run on low power systems such as the BBB.

Edit your package sources:

#+BEGIN_SRC: bash
emacs /etc/apt/sources.list
#+END_SRC

Append the following line:

#+BEGIN_SRC: bash
deb http://dev.gnutelephony.org/archive/ wheezy/
#+END_SRC

Save and exit.

To load the repository the first time after adding it to the sources.list, since you do not have the verification keys already installed yet. Then do

#+BEGIN_SRC: bash
apt-get install gnutelephony-keyring
#+END_SRC

After that it will be happy to accept it as a signed repository. The verification keys can also be directly fetched with

#+BEGIN_SRC: bash
cd /tmp
wget http://dev.gnutelephony.org/archive/wheezy/public.key
#+END_SRC

and manually added instead with

#+BEGIN_SRC: bash
apt-key add public.key
#+END_SRC

To make sure you have all dependencies, do

#+BEGIN_SRC: bash
apt-get update;apt-get dist-upgrade
#+END_SRC

Before we install anything, let's inspect what is available to us by using

#+BEGIN_SRC: bash
dpkg -l sipwitch
#+END_SRC

To see the main application. The columns will indicate if the package is installed, which version and a description of the package. Then do

#+BEGIN_SRC: bash
dpkg -l sipwitch-*
#+END_SRC

to see available supporting applications and plugins. Again, the columns will indicate if the package is installed, which version and a description of each of these.

To install only the main application, do

#+BEGIN_SRC: bash
apt-get install sipwitch
#+END_SRC

and to install all supporting plugins:

#+BEGIN_SRC: bash
apt-get install sipwitch-plugin-scripting sipwitch-plugin-subscriber sipwitch-plugin-forward sipwitch-plugin-zeroconf
#+END_SRC

Add your user into the sipwitch group

#+BEGIN_SRC: bash
groupadd sipwitch
groupadd sipusers
usermod -aG sipwitch myusername
usermod -aG sipusers myusername
#+END_SRC

Then edit the configuration

#+BEGIN_SRC: bash
emacs /etc/sipwitch.conf
#+END_SRC

Change the *mapped* value from 200 to 20, since we don't want to be serving huge numbers of calls.

Alter the *range* value to 10, since we don't need a large number of extensions.  This will mean that exension numbers 200 to 209 are available.

Do not set the *realm* value, as doing so seems to prevent the server from working.

Save and exit.

Create a digest string for your username:

#+BEGIN_SRC: bash
sipwitch digest myusername
#+END_SRC

Make a note of the resulting string because you're going to use it in the users file you'll now create.

#+BEGIN_SRC: bash
export HOSTNAME=mydomainname.com
touch /etc/sipwitch.d/$HOSTNAME.xml
chmod 600 /etc/sipwitch.d/$HOSTNAME.xml
emacs /etc/sipwitch.d/$HOSTNAME.xml
#+END_SRC

It should look something like the following:

#+BEGIN_SRC: bash
<provision>
    <user id="myusername">
        <digest>yourdigeststring</digest>
		<extension>201</extension>
		<display>Your full name</display>
    </user>
</provision>
#+END_SRC

Save and exit.  Now edit the configuration.

#+BEGIN_SRC: bash
emacs /etc/default/sipwitch
#+END_SRC

Change "desktop" to "server", then save and exit.

Update the IP settings:

#+BEGIN_SRC: bash
iptables -A INPUT -p tcp --dport 5060 -j ACCEPT
iptables -A INPUT -p udp --dport 5060 -j ACCEPT
iptables -A INPUT -p tcp --dport 5061 -j ACCEPT
iptables -A INPUT -p udp --dport 5061 -j ACCEPT
iptables-save
#+END_SRC

Test that it's working:

#+BEGIN_SRC: bash
pkill -9 sipw
sipw -x9 -f
#+END_SRC

Then try to register with the server using a SIP client (such as Jitsi). If everything worked then use CTRL-C to exit.  Then start the service.

#+BEGIN_SRC: bash
service sipwitch start
#+END_SRC

*** Clients
**** Jitsi
Download the latst version from https://jitsi.org/index.php/Main/Download

TODO
**** Twinkle client

The client should have a user profile as following:

The "user name" is the xxx id used in the <user id="xxx"> entry of /etc/sipwitch.conf

The "domain" is the yyy domain in the main config <stack><domain>yyy entry of /etc/sipwitch.conf

The SIP Authentication should have:

realm = realm as set in <registry><realm> of /etc/sipwitch.conf

authentication name = <user id="xx"> entry, same as "User Name" field.

password = value of <secret>zzz in <user> entry of /etc/sipwitch.conf

Under security tab, set "Enable ZRTP/SRTP encryption"
