This page is intended for [[ECE2524]] students and others new to the concept of console-based IRC clients.
== CVL SSH accounts ==The [[gp:Bradley Department of Electrical and Computer Engineering|ECE]] department offers shell ccounts on the [[gp:CAD and Visualization Laboratory|CVL]] for Virginia Tech affiliates. Accounts can be created at [http://computing.ece.vt.edu/accounts/ this page].
The ECE2524 VM (128.173.88.125) can be accessed via SSH for CVL users, and has tmux, mosh, and weechat installed. Acidburn (acidburn.vtluug.org), the VTLUUG shell server, has a few more IRC clients installed, as well as other software <s>and full IPv6 support</s>. The [[gp:CAD and Visualization Laboratory|CVL]] does ''not'' have any IRC clients installed, but is useful for general computing (e.g. [[MATLAB]]).
One advantage of a shell account is that it allows one to leave an IRC client constantly connected, eliminate join/quit spam, and log missed messages to check later. In order to accomplish this, the IRC client must be run inside either [[tmux ]] or [[screen ]] so that it will not be killed when you disconnect from SSH.
Here's the procedure for using either the ECE2524 server or acidburn for IRC:
#* <code>^b-d</code> (that is, press Control-b, then d)
#* ''Use this whenever you are inside a tmux window and wish to return to a shell''
# To, reattach to the first tmux seesion, just use <code>tmux aattach</code>
#* <code>user@ece2524:~$ tmux attach</code>.
#* ''On subsequent logins, this should be the only command you need to execute to return to IRC''
Check out the [http://www.dayid.org/os/notes/tm.html tmux and screen cheat sheet] for a quick reference of some of the other tmux commands. An additional command that might be useful is <code>tmux list-sessions</code>.
[http://mosh.mit.edu Mosh] is another helpful tool you may want to use for high-latency or mobile (e.g. wifi) connections. You also may want to look into zsh, an alternative to bash with more features.
You also may want to setup an [http://nerderati.com/2011/03/simplify-your-life-with-an-ssh-config-file/ SSH config file] for host aliases and Kerberos authentication.
'''If you have been given a temporary password please reset it by running<code>user@acidburn:~$ passwd</code>''' ==Other SSH suggestions==* Use SSH Keys* Write up your own [[tmux|tmux.conf]]* Use X-forwarding on servers that support it: <code> ssh -X user@client.server.tld </code>
