 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".
 
 
 Then save and exit.

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.

-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.

 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.
 
 
 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]].

 An alternative is to use a decentralised mailing list, implemented using Bitmessage.  On your local machine (not the BBB) you can make a private mailing list which is difficult to censor and where there is no single point of failure.  This type of mailing list is known as a "/chan/".
 
-With Bitmessage if any one computer goes offline then the conversation can still keep going since there is no central mailing list server.  Bitmessages are also encrypted with public/private key pairs and the manner in which the system operates makes it very difficult for the surveillance apparatus to exfiltrate the social graph of list users.
