Usage Guide

Torchwood 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 ssh username@ssh.tardis.ed.ac.uk 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.

The old SSH server Vortis is still accessible, at ssh user@vortis.xen.tardis.ed.ac.uk but will be taken down in the next couple of months.

Shell Server

We run OpenSSH latest authenticated against LDAP. The primary shell login host is Vortis which runs Linux. The SSH server will be switched over to Torchwood soon. To log in ssh user@ssh.tardis.ed.ac.uk. Please be aware that the new SSH server Torchwood is running a temporary ban service to mitigate brute force attacks; Bans will expire after around 20 minutes of inactivity.

Dumping Screen Sessions, Weechat, Irssi, etc.

We have a new login server, fez which will be up and running at the same time as we switch over to Torchwood for SSH. Please dump your screen sessions and stuff you want to persist there, as it's a beefy VM that'll get imaged between shutdowns. Torchwood will also be nerfed to dissuade people dumping stuff on it.
