A twiki for the group has been setup at:

https://ppes8.physics.gla.ac.uk/twiki

It's world readable but in order to edit pages you have to register and then send a request to ppesysman@physics.gla.ac.uk to put you on the allowed editors list.

The twiki is divided into several sections - webs in twiki parlance. At the moment there are ATLAS and DetDev webs as well as the usual twiki Main, TWiki and Sandbox webs and the ppeit wiki will be moving over to the twiki at some point. Just let me know what other webs are needed.

Once the twiki is working smoothly the url will change so it is accessible via a ppewww.physics.gla.ac.uk address but that will not be for a few weeks.

Local copies of the twiki documentation including the getting started tutorial can be found on the twiki in the TWiki web.

The machine serving the home areas (ppes1) suffered a kernel oops again is this afternoon and rebooted. It's now back up and running.

Apologies for this I had thought the problem had been understood and worked around a month ago when the machine last had a kernel oops.

In order to try and fix this problem fully the plan is to change the motherboard on the machine for one identical to the motherboard in the second disc server. This will need half a days down time (during a weekday) to do and will require first backing up all the data on ppes1, which will take a few days to a week to do.

The linux desktops will be updated from scientific linux 4.4 to scientific linux 4.6 over a next two weeks. This is an update between minor release versions and only needs the installed packages updated and then the machine to be rebooted. This can all be done remotely and only takes a few minutes. So as and when no one is logged onto a specific machine it will be updated and rebooted.

This should not affect any code as minor release versions are binary compatible but if the update does cause problems please let me know. The version of scientific linux runing on a particular machine can be checked by looking at the file /etc/redhat-release for an sl4.6 machine it contains:

Scientific Linux SL release 4.6 (Beryllium)
