IRC

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.

Irssi

The easiest way to use irssi is to connect to your system, like this:

ssh myusername@mydomain -p 2222

Then select IRC from the menu. However, other than via this method using ssh, irssi isn't a very good IRC client because it doesn't have the capability to onion route messages, and therefore leaks metadata. For the best security when using your IRC server, use HexChat, Emacs ERC or another client which supports socks5 proxying.

HexChat

HexChat (formerly XChat) is compatible with proxying via Tor and so provides the best security when connecting to your IRC server. It will allow you to connect to your IRC server's onion address.

First install HexChat and set up its configuration file. This can be done on your local machine with:

freedombone-client --setup hexchat

Now look up the onion address for your IRC server

ssh username@mydomainname -p 2222

Select Administrator options, then About this system and make a note of the onion address for IRC. Also select the IRC Menu and take a note of the login password.

Run HexChat.

Within the network list click, Add and enter your domain name then click Edit.

Select the entry within the servers box, then enter ircaddress.onion/6697 or mydomainname/6697 and press Enter.

Uncheck use global user information.

Enter first and second nicknames and check connect to this network on startup.

If you are using the ordinary domain name (clearnet/ICANN) then make sure that Use SSL is checked.

If you are using the onion address then use SSL should be unchecked and the transport encryption will be handled via the onion address itself.

Within the Password field enter the password which can be found from the IRC menu of the control panel.

Select the Autojoin channels tab, click Add and enter #freedombone as the channel name.

Click close and then connect.

Emacs

If you are an Emacs user then you can also connect to your IRC server via Emacs.

Ensure that tor is installed onto your local system:

sudo apt-get install tor

Add the following to your Emacs configuration file:

(setq socks-noproxy '("localhost"))
(require 'socks)
(require 'tls)
(setq socks-server (list "Tor socks" "localhost" 9050 5))
(setq erc-server-connect-function 'socks-open-network-stream)
(setq erc-autojoin-channels-alist
    '(("myircaddress.onion" "#freedombone")))
(erc :server "myircaddress.onion" :port 6697 :nick "yourusername" :password "your IRC password")

Changing or removing the IRC password

By default the IRC server is set up to require a password for users to log in. The password is the same for all users. If you want to change or remove the password:

ssh myusername@mydomain -p 2222

Select Administrator controls then IRC Menu and then change the password. An empty password will allow anyone to log in, so you can have a globally accessible IRC system if you wish, although you might want to carefully consider whether that's wise.
