This page is intended to be the document that outlines the practices and procedures used to maintain abbot. Additionally, it may contain information about downtimes and upgrades.

1 Platform Notes

abbot is an HP ProLiant DL120 G6 equipped with

  • quad-core 2.40GHz Xeon X3430 processor
  • 8 GB RAM
  • 680GB RAID-1 filesystem
  • Debian lenny amd64

Most user-maintained directory trees are backed up nightly: /etc, /home, /opt, /srv, /usr/local, and /var.

2 Account Creation

Once someone has been approved for an account, the new user should submit three items:

  1. a preferred username
  2. a valid public SSH key: password logins are discouraged and may be disallowed in the future
  3. an e-mail address: abbot does not spool mail; outbound mail needs to be rewritten with a valid off-site address

When those are received, the account can be created:

  1. adduser --disabled-password --gecos "Full Name" newuser
  2. chmod -R go-rwx /home/newuser
  3. Add new user to any necessary supplementary groups: cvs, haskell, hackage, ...
  4. install public SSH key as /home/newuser/.ssh/authorized_keys
  5. add off-site e-mail address to /etc/aliases and /etc/email-addresses

A user password should only be created when that person needs sudo privileges.
