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.

*** Red Matrix
|
||||
**** Introduction
|
||||
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.

#+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.

|
||||
|
||||
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]].

|
||||
|
||||

** 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.
