 If you wish to only use ssh keys then log in to the Freedombone, become the root user and open the control panel with the 'control' command. Select /Security Settings/ then keep hitting enter until you reach the question about allowing password logins. Select "no" for that, then apply the settings. Any subsequent attempts to log in via a password will then be denied.

+* Administrating the system via an onion address (Tor)
71
+You can also access your system via the Tor system using an onion address. To find out what the onion address for ssh access is you can do the following:
72
+
73
+#+BEGIN_SRC bash
74
+ssh username@freedombone.local -p 2222
75
+sudo control
76
+#+END_SRC
77
+
78
+Then select "About this system" and look for the onion address for ssh. You can then close the terminal and open another, then do the following:
79
+
80
+#+BEGIN_SRC bash
81
+sudo apt-get install tor connect-proxy
82
+echo 'Host *.onion' >> ~/.ssh/config
83
+echo 'ProxyCommand connect -R remote -5 -S 127.0.0.1:9050 %h %p' >> ~/.ssh/config
84
+ssh username@address.onion -p 2222
85
+#+END_SRC
86
+
87
+Subsequently even if dynamic DNS isn't working you may still be able to administer your system. Using the onion address also gives you some degree of protection against corporate or government metadata analysis, since it becomes more difficult to passively detect which systems are communicating.

 Both Hubzilla and GNU Social try to obtain certificates automatically at the time of installation via Let's Encrypt. This will likely mean that in order for this to work you'll need to have obtained at least one "official" domain via a domain selling service, since Let's Encrypt mostly doesn't seem to work with free subdomains from sites such as freeDNS.

 IRC is useful for multi-user chat. The classic use case is for software development where many engineers might need to coordinate their activities, but it's also useful for meetings, parties and general socialising.

 The default XMPP client in Ubuntu is Empathy.  Using Empathy isn't as secure as using Jitsi, since it doesn't include the <i>off the record</i> feature, but since it's the default it's what many users will have easy access to.

 Tor Messenger is a messaging client which supports XMPP, and its onion routing enables you to protect the metadata of chat interactions to some extent by making it difficult for an adversary to know which server is talking to which. You can download Tor Messenger from <a href="https://torproject.org/">torproject.org</a> and the setup is pretty simple.

 Tox is an encrypted peer-to-peer messaging system and so should work without Freedombone. It uses a system of nodes which act as a sort of directory service allowing users to find and connect to each other. The Tox node ID on the Freedombone can be found within the README within your home directory. If you have other users connect to your node then you will be able to continue chatting even when no other nodes are available.

 Freedombone also supports SIP phones The username and domain is the same as for your email address, and the SIP password and extension number will appear within the README file in your home directory. Various SIP client options are available, such as CSipSimple on Android and Jitsi on desktop or laptop machines. Ideally use clients which support ZRTP, which will provide the best level of security.
