ejabberd back up
After some technical difficulties it was unearthed that porting a Mnesia database (such as that used by erlang) from one machine to another is insanely difficult. I eventually gave up and as a result everybody has to re-register their accounts. Please do so under @tlug.org.za as I also took the opportunity to change the authoritative domain name for ejabberd.
The one big downside of all of this is that all rosters was lost. I can partially recover rosters on demand, so please do contact me via jabber (jkroon@tlug.org.za) and I’ll happily supply you with what I can dig out. Appologies for the inconvenience.
Server pics: old and new
TLUG Servers: Old on the left, New on the right
This is cluon, the TLUG server. The old one was a AMD Duron 900Mhz with 512MB RAM and first 60, then 20GB of disk space. It was donated by Prof Barnard (then with Electronic Engineering) and it served us well for many years before it developed old-age instability.
The new server is a nice rack-mounted Intel Core 2 Duo E7300 2.66GHz with 1GB RAM and 250GB disk space. It was donated by Jaco Kroon from Ultimate Linux Solutions.
Cluon is hosted by the friendly folks at UP Bioinformatics in their server room.

Server Switch
As some comments on the “sample” post indicated a number of people noted that the server is no longer the server.
We’ve swapped out the server for a (hopefully) more reliable machine, with some extra RAM and HDD space. What happened to the forums was an unfortunate accident, the wiki is still available under /wiki but we want to see if wordpress doesn’t work better for us. It gives us a more hierarchical structure, allows us to function by adding “posts” or “pages”. If this doesn’t work out too well, we’ll probably have to roll back.
Simeon did all of the work in terms of installing and getting the hardware swapped around, so a great deal of thanks goes out to him. He put a very significant amount of effort into this change-over, including setting up Wordpress for us, moving over all the old data from the old server (which is now resting in peace).
I think jabber is the only service that has not yet been completely migrated and I’ll work on that over the weekend, also figuring out a bit more about the WordPress permissions etc.
