Hi there, I did "read" the script - which has a lot of "comments" -
which are actually the source for the man page - but I missed those
comments that could have led me to the section where anonymous processes
are killed. :/ Any perl wizzard following? Have a look at the tarball at
http://ftp.skolelinux.no/debian/pool/main/k/killer/ - please! [1]

Yes, this script is there; also nightkill.sh which could be an
alternative to killer. Anyway debian-edu-config seems to be the right
package to place such maintainance scripts.

Please follow recent IRC log on #debian-edu to find some alternative
approaches on clearing left-behind processes deliberately (rather than
killing arbitrary unidentified processes).

P.S.: I dare place a copy of the "killer" perl script to Debian pastebin
- so you perl wizzards can find a way to regard user IDs of logged in
users (-> last; who). It's on:
