AG DSN

Just like last month, we'll report a few interesting events that happened to us. In case you missed the last post, you can read it here: https://agdsn.de/sipa/news/2024-05-01-april-at-agdsn

On 7th of May, after a meeting of our "Team Network", people sat down to update the software of our old core router. As you hopefully haven't noticed, no problems occured. Thanks to the fact we've migrated our uplink to the new core routers on March 16th, this've been much more relaxed than it would have before.

Some technical details: the old core router consists of three physical devices, united to to a single logical one. Therefore it's name, "Ianus". Each of the three devices is a FlexFabric 5900 from HPE.

The new routers are a group of three Omniswitch 6900-V72 from Alcatel-Lucent Enterprise, they remain seperated logically though.

We didn't only maintain our technical connections but also our social ones. For that purpose we held our "Jahresessen" (annual dinner) on 29th of May. Just like in past years, we've had vivid discussions with people doing research and teaching at TU Dresden, the Studentenwerk, the "Zentrum für Informationsdienste und Hochleistungsrechnen der TU Dresden (ZIH)" as well as with companies we are in contact with, e.g. for procurement of network hardware.

Last but not least, an addendum to last months post: as we received reports about issues with the WLAN coverage, we've installed one more wireless access point manufactured by Aruba in five levels of the International Guest House on the 24th of April.

And that's the end of this months post! You're in the mood organising our next Jahresessen or other events? Join our Team Festivities! Take a look at https://agdsn.de/sipa/meetingcal for the next meetings. Any questions left? Write an email to du-bist-gefragt@agdsn.de.

What does the AG DSN actually do? Below a few highlights from the past month April.

On April 7th, a few active members met at the NOC, our large office, for Tux sewing. Fabrics were bought the day before. The goal was to manufacture two penguins, a blue and a orange one.

Orange, that's the color of the student network „Selfnet“. On April 13th, it celebrated it's 25th anniversary, five active members of the AG DSN took part. During the event, the orange Tux found a new home.

Last but not least, a bit more technical topic: for internal communication, the AG DSN runs a Mattermost as well as a XMPP server, Prosŏdy. Starting from April 16th, a Coturn joined the Prosŏdy to provide STUN as well as TURN functionality. With these services in place, active members can now initiate audio and video calls via XMPP.

Not mentioned in this post are the numerous unspectecular tasks, being accomplished everyday: answering email tickets, providing support in person, bank imports and many more.

The required configuration for our WiFi's "agdsn" as well as "IGH" must be adjusted until November 13, 2023.

Important: This does not affect the WiFi that your router emits! It only affects "agdsn" and "IGH".

In order to use our WiFi without interruption, you should take action now by changing the following entries in your WiFi configuration:

• The Anonymous identity is now "wifi@agdsn.de". Other entries are not permitted and will not work.
• If CA certificate has been set, it must either be configured to use the system certificates (depending on the operating system, this option may be called "Use system certificates") or a new certificate must be downloaded and selected.

Starting from November 13, 2023, other configurations will no longer work and will result in the WiFi being no longer usable until the configuration has been adjusted.

You can find more information about the setup of our WiFi including an installation wizard on the corresponding information page.
