abbot.galois.com is the current physical machine that hosts several widely used Haskell virtual hosts:
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 DL12 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.
Questions or requests for help can be addressed to email@example.com.
2 Account Creation
Once someone has been approved for an account, the new user should submit three items:
- a preferred username
- a valid public SSH key: password logins are discouraged and may be disallowed in the future
- 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:
- adduser --disabled-password --gecos "Full Name" newuser
- chmod -R go-rwx /home/newuser
- Add new user to any necessary supplementary groups: cvs, haskell, hackage, ...
- install public SSH key as /home/newuser/.ssh/authorized_keys
- 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.
