(all in English)As many has noticed it can be a hard time to log on to K-nets firewall (fw2) doing the time interval from 16-23, especially Saturdays and Sundays.

The problem is not at Nybrogård dormitory but at the firewall server at DTU.
The server cannot handle the pressure of the many user logins on doing this time period, due to lack of memory.

Personnel at K-net are aware of the problem and didn’t want to disturb the examperiod. Also they are voluntary and don’t get paid for their work, therefore they have not had the time to get the work to be done.

Within the next period of time K-net will work on a new system or an upgrade of the exiting system. Until then you have to be patient.

The more technical term for the lack of memory in the server: Every time a user logs on, a small amount of memory are reserved for that user and when the server reach about 1500 simultaneous users it runs out of memory and all CPU power are used for interrupts and errorhandling therefore the users able to login will notice it takes some time, others see a connection timed out for both servers.

I hope this will clean things a bit.

If you need to address the anything about the problem you should go the the K-net forum (http://www.k-net.dk/tiki-forums.php)
