Research Administration Tasks

Adding users

• • As root on yamato, run
    /usr/local/sbin/diradm.superadduser '$username' '$email' '$Fullname'
  • Note that a file named '$username' is created in your current directory with the template filled out for mailing (the same file is displayed onscreen).
  • For now, we must:

export DEBUG=1
DEBUG=1 /usr/local/sbin/diradm.superadduser ...

• • The password you are prompted for at the end is for hood
  • Add the newly-created user to our Research Mailing List

Adding groups

• • As root on hood, diradm groupadd
  • same syntax as groupadd(8).
• Adding or removing users from a group
  • same syntax as gpasswd(8)
  • As root on hood, diradm gpasswd (-a|-d) USERNAME GROUP

Adding projects

• • As root on hood:
    diradm amadd -O $mapbase $key $src
  • '-O' means the default mount options for automount.
  • As root on yamato: create the $src directory now, and give it the approriate permissions. chgrp -R it, and chmod 2771 it.
  • Make the directory. mkdir -p $src
  • Set ownership. chgrp -R $group $src
  • Set permissions. chmod 2771 $src
  • If web content is being served: mkdir -p $src/htdocs ; chmod 2775 $src/htdocs

Adding CVS repositories

• On hood, run diradm amadd -O auto.cvs ${foobar} 209.87.56.240:/export/cvs/${foobar}
  • Replace ${foobar} with the name of the repository
• On yamato, run (assuming there's a previously created group called ${foobar}:
  • cvs -d /export/cvs/${foobar} init
  • chmod -R 2770 /export/cvs/${foobar}
  • chgrp foobar /export/cvs/${foobar}
  • The chgrp command can instead be a chown command for a single user repository; group name and cvs repository name don't have to match, either.
• To access CVS repo, use CVS_RSH="ssh" with URL being :ext:${user}@cvs.iat.sfu.ca:/var/cvsroot/${foobar}
• Users must be in group cvs in addition to ${foobar} to access the repository!

Adding SVN repositories

• On hood, run diradm amadd -O auto.svn ${foobar} 209.87.56.240:/export/svn/${foobar}
  • Replace ${foobar} with the name of the repository
• On yamato, run (assuming there's a previously created group called ${foobar}:
  • chmod -R 2770 /export/cvs/${foobar}
  • chgrp foobar /export/cvs/${foobar}
• On nelson, run svnadmin create /var/svnroot/${foobar} --fs-type fsfs
• Repo URL is svn+ssh://${user}@cvs.iat.sfu.ca/var/svnroot/${foobar}
• Users must be in group cvs in addition to ${foobar} to access the repository!

General user management

• • diradm offers almost all regular POSIX commands, sometimes with a few extra frills. The only commands NOT completely implemented are gpasswd and passwd.
• Gentoo update procedures (eg, how to update without ever messing up a machine).
  • TODO
• Welcoming new users; email template or typical wording you've used
  • This is in the diradm.superadduser script, as it fills out the template.

Customizing Logwatch

There are two basic customizations which we often perform:

1. increase the header-information with machine-specific info (hardware, admininstrator(s), usage, etc)
2. adjust the order of the information - we care very much about disk-usage, and prefer it first

• use this template, to create /etc/log.d/custom_header

• modify logwatch.pl to add the bold / red line:
  • on a RedHat 9 machine, this file is /etc/log.d/scripts/logwatch.pl
  • on a Gentoo machine, this file is /usr/sbin/logwatch.pl
