Overview
Most machines are running Ubuntu 6.06 (long term support). I hope
to upgrade them all soon, to 8.04 LTS.
Facts about the Linux environment
- the Linux distributions used are Ubuntu LTS 6.06.1 and 8.04 LTS
- up to
date operating system, libraries, software, user interface
- actively maintained and updated
- every computer has a name such as name.ais.sandbox, denoting that
it lives inside a local subnet, not seen from outside (the internet
at large)
- more secure
- to connect to it from outside campus, an ssh connection must be
made first to a CSLab time share server such as
apps0.cs.toronto.edu
apps1.cs.toronto.edu
apps2.cs.toronto.edu
apps3.cs.toronto.edu
and then another ssh connection to name.ais.sandbox
- the home directory is mounted (for those who gave permision to the
POC) but personal website space must be mounted individually
by every user via Samba (more details in the
FAQ
); these directories
are backed up by Core
- work directories (e.g. /w/199) of each group are mounted if
permission was give to the POC; these directories are not
backed up
- special purpose directories such as /cs/lists or /var/mail
are not mounted on machines running the new operating system. There
are various ways to read email outlined in the
FAQ,
the simplest being
with an IMAP capable client, such as Thunderbird, installed by default.
