Information / Documentation Sources

This TWiki Web (the IT Web) accessable at covers PPE specific IT issues. Please take the time to look at the TWiki for IT information. If the layout of the TWiki is confusing then please use the TWiki search function. The search link is to the upper part of the left hand sidebar of TWiki pages. The TWiki has several other Webs (ATLAS, DetDev, ScotGrid) and well as the TWiki Web which contains documentation on using the TWiki.

For departmental matters there is the IT Matters web site, which amongst other things has the list of wireless access codes.

The group has a small printer room (484) which contains colour and black and white printers. These are available from linux, windows and osx. The GroupPrinting page and subpages detail how to use and install these printers.


The PPE file servers store peoples home directories (/home/xxx) and data directories (/data/xxx) for the different experiments. These are available (automatically) via nfs on the linux desktops and via samba in the windows desktops. See FileStorage.

Files in users home directories are backed up overnight and keep for upto six months. See Backups. The /data areas are not backed up, with the exception of /data/ppemgr01 and /data/www01 which are backed up.


PPE linux passwords can be changed on any PPE linux desktop with the passwd command.

System Manager

PPE IT is managed by the ScotGrid team in room 427. E-mail should be sent to See SystemAdministrators.
