LTSP server maintenance (plimpy)
http://nic.phys.ethz.ch/news/1211953704
On Wednesday May 28 our LTSP server plimpy will be offline for some
minutes around 7:30 a.m. We will upgrade RAM to 8 GB and install a new
PSU. If you're using one of our alix thin clients, please make sure to
have all your work saved.
Update 07:45: plimpy has 8G now. Use it wisely.

Weak SSH and SSL keys
http://nic.phys.ethz.ch/news/1210776776
It [1]has been discovered that the random number generator (RNG) of
Debian's OpenSSL package in their current stable release "4.0 Etch"
and later (and those OpenSSL packages based on it as those from e.g.
Ubuntu) generated predictable randomness which means that all keys
generated with OpenSSL (e.g. SSH keys, website certificates, etc.) on
our managed Linux workstations and other Etch machines are guessable
with less effort than assumed. These keys need to be regenerated.
This means that if you connect to some of our Linux workstations SSH
or Putty will argue about a changed host key.
This also means that if your personal SSH key has been generated on a
Debian (or Ubuntu) with the broken OpenSSL RNG your key will no more
from our workstations (or any other uptodate Debian system) and you
will be prompted for your D-PHYS password instead.
Read on to find out if your keys are weak, what other services and
keys may be affected and how you can generate new keys if necessary.
We will add more information to this article as it becomes available.

E17 Window Manager
http://nic.phys.ethz.ch/news/1209726487
If you are like me and feel that FVWM does not meet your expectations
of a modern window manager, but at the same time don't like the bloat
of KDE or Gnome, you might want to give [1]Enlightenment a try. It is
extremely fast, sports many amazing-looking themes, and has been my WM
of choice for many years now.
Read on to learn how to use E17 on our managed Linux workstations
(including thin clients)
