Vortis runs the primary shell login service for Tardis, externally accessible via
ssh.tardis.ed.ac.uk. In order to log in to the Tardis systems you will need to obtain an SSH client. For those with Linux/Unix systems, you should be able to run
from a command shell. For those in Windows, you are advised to have a look at PuTTY. Use this to connect to ssh.tardis.ed.ac.uk, giving the supplied username and password.
You can change the password on your new account using
passwd from the command line, and you are advised to do so on your first log in. You can read your mail off the system using pine, or whatever your preferred mail client is.

Screened Irssi Timeouts
For some time we had a problem with IRC sessions running between screen(ed) irssi(s) on gallifrey and the IRC Service timing out. This was not down to a networking problem, but to a feature of screen, where it "waits until the display restarts to accept the output". This was happening when ssh timeouts occurred or when a user pressed ctrl+s and was rather annoying for other IRC users.
The solution, suggested by Patrick (not bung), was to add 'defnonblock on' to /etc/screenrc so that screen's default behaviour was to use an internal 1s timeout on the "display" (ssh in this case). Once this timeout is reached, screen will restart accepting output from its children and buffer it as it would if the screen were detached.
