== Before beginning to migrate members ==

 * Megacz
    * Make /afs/hcoop.net/common/etc/scripts/apache-sync-logs work
 * mwolson
    * Upgrade deleuze to debian etch
    * Install denyhosts on both deleuze and mire, needs debian etch
    * Switch ssh on deleuze to listen to port 22, needs denyhosts
    * Perform testing on procmail and exim filter on deleuze.
    * Migrate site-specific (read: non-AFS) changes to apache 1.X on mire (read: check to see if this has already been done).

== During migration == Links to detailed policies, procedures and information specific to HCoop. The resources here should allow HCoop admin team members to share information about every part of the complete system, and to allow easier training of future team members.

 * Unclaimed
   * Watchdog process to kill resource hogs
   * Make ca@hcoop.net e-mail address working. It's the address that will be used in the certificate files.
   * Make sure somebody is reading mail sent to abuse@hcoop.net so we don't wind up on lame DNSBLs
   * Fix resolv.conf on both servers to have multiple good DNS servers for now, set it to use localhost once BIND is running and configured.
   * Figure out how to use Dell OMSA or other tools to monitor RAID and other hardware.
   * Migrate ejabberd mnesia db just before the dns switchover.
   * Set up back-up regime, possibly using [http://rsync.net/ rsync.net].
   * Get miscellaneous web stuff ported, like membership application, vmail password change, publicly-viewable statistics on membership, bandwidth usage stats, ....
   * Do performance testing on the new configuration, by having admins or other users monitor performance on mire (using vmstat, top, mytop, etc) and having one or more (perhaps multi-threaded) scripts requesting web pages from somewhere off of the Peer 1 network.
 * mwolson
    * Run simple tests on cron to see if it works.
    * Mailman
      * The exim side of things has been mostly set up.
      * I think I migrated the non-exim stuff as well, but will need to double-check.
      * Need to think of a way to test this, perhaps with help from a migrated user.
Admins: it is recommended that you create a wiki account and subscribe to the page regex `.*` (all pages) to keep informed of what everyone is up to. Then, please document all of your work on here somewhere - that way we will not only have a record, but get emailed when it is done.

will let you know all the relevant subpages. From my experience, I would recommend longer pages, instead of dividing a topic into lots of subpages. When there are too many subpages, I've found that some will be updated, and some will fall out of date. (Of course, use your judgment here.)

 * To edit LDAP database from a GUI tool, use ''gq'' program
 * To connect to hcoop's ldap server using ''gq'', create a SSH tunnel: ''' ssh -p 2222 -f -N -L 389:localhost:389 USERNAME@69.90.123.67''', and then connect to ''localhost:389'' in ''gq''.

This machine donated by Justin Leitgeb seems real nice. Buffered disk throughput is about 1.5 GB/s. Raw disk reads are 60 MB/s for the two 36 GB disks and 120 MB/s for the 4-disk array. Not bad at all. === Introductory material ===
Line 70: Line 29:
 * Removed excessive packages, cleaned up the system
 * Installed ''changetrack'' to monitor all config file changes. The program uses ''rcs'' and automatically keeps previous revisions. It is ran from ''cron'' on a daily basis.
 * Installed ''debsums'' to monitor file md5sums
 * Installed Courier IMAP and IMAP-SSL
 * Installed LDAP for user authentication. The system is currently configured to use LDAP and fallback to the usual ''/etc/'' files. Admin users will be added locally on all machines and will be able to log in even when LDAP is not operational.
 * Installed MIT Kerberos 5
 * Fixed date/time on the system. Installed ''ntpd''
 * Installed TLS support for LDAP. Certificate file is ''/etc/ldap/server.pem'', and ldap/ldaps ports are 389/636.
 * Installed Linux 2.6.18.3-grsec with 2.6.18-mm3 patches (2) for megaraid.
  * The patches and source tree installed, along with the .deb generated, is under /usr/src/ntk2. I set up sockets groups as on fyodor (7070-7072). SMP, with hyperthreading enhancements, is enabled. I also installed a bunch of packages that someone were uninstalled while I was gone (e.g., gcc). I also fixed the sudoers, wheel group, and admin home directories. --NathanKennedy
 * Kerberos + LDAP works.
 * Compiled requisite kernel modules, compiled and installed new OpenIPMI package, and installed dellomsa. Dell OMSA is now working. --NathanKennedy
 * Install SSH.
 * Permit new admins to log in by copying their SSH keys to their newly-created (empty) home directories.
 * Install AFS (need to repeat the reading on AFS and how it really works. Also it will influence the decision how to format ''/dev/sdb'' in the system) -- DavorOcelic
 * Install MySQL and PostgreSQL (input from AFS step and admin discussion needed to see how to exactly configure this).
 * Install BIND.
 * Install and configure Apache, to serve static web content only. --MichaelOlson
 * Review kernel configuration and install testnet. -- DavorOcelic
 * Configure exim4. --MichaelOlson
 * Configure Courier IMAP daemons, reviewing fyodor's config. --MichaelOlson
 * Migrate squirrelmail configuration settings from fyodor.
 * Configure Squirrel``Mail to use imapproxyd, which should give speed improvements once we migrate to deleuze. --MichaelOlson
 * Exim filters
    * (a method has been set up by MichaelOlson, but it needs testing).
 * DNS server
    * Works on deleuze, although I will test once more domains have been migrated for reasonable domain defaults --JustinLeitgeb
 * nscd process for name caching
    * Currently this processes is set to do hostname caching on deleuze, so bind will not be set up as a caching name server --JustinLeitgeb
 * Get exim working on mire --MichaelOlson
Refer to documentation of each of the listed components. The information in our Wiki pages covers only the most basic principles, and quickly focuses on HCoop-specific setup, assuming skillset with the technology.
