Project @ iMath

During the day we encountered different problems with the two new thinlinc servers tl15 and tl16.
The main problem was 'no access from outside of the institute' - multiple firewall and ssh configurations issues caused this.
We apologize for the trouble.

A technician removed accidently a power cable from a main network switch in our server room - the institute has been 8 minute offline: no web, mail, thinlinc.
Now, everything should be normal again.

The work in the server room is related to 'VoIP preparation' on 21.10.15.

Sorry for the trouble.

In order to improve the performance of the ThinLinc System, we added two additional ThinLinc Servers.

If you feel your session being slow, please log off of your current ThinLinc session and do a fresh login.

Sage has been updated to version 6.8, which is now the default.

All Thinlinc sessions now start a small applet in the upper right corner to display the latest I-MATH IT News.

The IT group uses this channel to inform thinlinc users about the latest updates, warning and reminders.
The icon starts blinking as soon as a new message arrives.

We updated all of our wikis from the 'moin moin' standard design to a more UZH CD friendly look.

To make it more clear that the wikis are hosted inside the institute, we incorporated a more UZH CD friendly design for all of our internal and public wikis.

We also changed the message 'you do not have permission to view this site' to be more clear that you should login to the wiki first. The standard message was confusing and didn't point you to where you could login.

It seems that the new filesystem share have been offline for awhile.
The problem has been fixed and the files will be monitored in the future.

The SSH server has been crashed.

The Institutes SSH server has been down 17.9.15 22:00 - 18.9.15 07:30. It seems that the OS had some memory problems. After a reboot the problems has been disappeared.

A new method to offer file downloads via homepage to the students

In the past, all lecture files (exercises, scripts, solutions, notes, ...) had to be uploaded via a webinterface in LI.
From now on, there is a second possibility: copy the files to `/scratch/share/vorlesungen/<module>/<semester>/web` and they will be displayed.
