Network maintenance in the autumn break

Friday 14 October 2011, 13:14

During the Autumn break you will experience downtime due to maintenance on our network infrastructure located here at the dormitory and at K-Net as well. We are upgrading our network equipment so that the K-net Utilliy will become obsolete.

Specifically Monday 17th from 12 noon to 5 PM K-Net has announced that they will be changing core equipment and the internet connection will be unavailable. During the next days until Thursday K-Nets website might be unavailable in periods, and mails sent to @nybro.dk and @k-net.dk addresses might be delayed in periods.

This upgrade will also affect the Wireless Network.

We will do our best to keep you updated on www.nybro.dk/for-beboere/nyheder

For the technically interested, the work during this upgrade is the following:

We will reconfigure our network switches so that each room plug on the wired network has its own VLAN. This will enable K-Net to do the traffic counting and by law required traffic logging without the K-Net Utility. We will be changing the main switch to support this.

K-Net will set up a new firewall which will take over from FW2 with settings for the new VLAN setup. K-Net will setup new switches and two new servers (DNS, mail, management, etc.) to work together with the new firewall. They will also be changing rack closets.

The wireless network and kitchen computers will remain with the old system with the K-Net Utility and FW2 a little longer, but will also eventually be free from the K-Net Utility. We will be changing at least one switch in each block to support this, but we do not expect that the new switches can be delivered in the autumn holidays.

While not being 100% certain yet, as it has not yet been approved by the board of K-Net, the idea is that the traffic limit will be much higher than now, and will be more “soft”. If you exceed the traffic limit you will have limited internet speed instead of being blocked completely. It is also planned that it should be possible to choose to have your incoming ports open.

Because the wireless network and the kitchen computers will be running on the old system for at while longer, the old traffic limit will still be in place there.

Sincerely,

The network group at Nybrogård Kollegiet.
