Wie schon im letzten Monat berichten wir euch auch in diesem wieder von einigen interessanten Dingen, die bei uns passiert sind. Solltet ihr den letzten Beitrag verpasst haben, könnt ihr hier nachlesen: https://agdsn.de/sipa/news/2024-05-01-april-at-agdsn

Am 07. Mai wurde, nach einer Sitzung des Team Network, die Aktualisierung der Software unseres alten Core-Routers angegangen. Wie ihr hoffentlich nicht gemerkt habt, lief das ohne Probleme. Dies ist nicht zuletzt auch der Migration unseres Uplink auf die neuen Core-Router zu verdanken, die bereits am 16. März diesen Jahres stattfand.

Bei dem alten Core-Router handelt es sich um drei physische Geräte, die zu einem logischen zusammengefasst sind. Passend dazu sein Name: „Ianus“. Bei den Geräten handelt es sich jeweils um FlexFabric 5900 von HPE.

Auch die neuen Core-Router sind zu dritt, verbleiben allerdings logisch getrennt. Gerätetyp sind hier drei Omniswitch 6900-V72 von Alcatel-Lucent Enterprise.

Neben den technischen galt es auch die sozialen Verbindungen zu pflegen. Zu diesem Zweck fand am 29. Mai unser Jahresessen statt. Wie auch die vergangenen Jahre wurde sich dort munter ausgetauscht, mit Lehrenden und Forschenden der TU Dresden, dem Studentenwerk, dem Zentrum für Informations­dienste und Hochleis­tungsrechnen der TU Dresden (ZIH) oder Unternehmen mit denen wir beispielsweise zur Beschaffung von Netzwerktechnik zusammenarbeiten.

Zuletzt noch ein Nachtrag aus dem April: wir versorgen alle Bewohner:innen des Internationalen Gästehauses (IGH) mit WLAN, wobei in mehreren Zimmern zuletzt Empfangsprobleme festgestellt wurden. Zur Verbesserung der Abdeckung wurden am 24. April in fünf Etagen jeweils ein weiterer Aruba Access Point installiert.

Damit sind wir auch schon wieder am Ende vom Mai angekommen. Falls ihr jetzt Lust darauf habt unser nächstes Jahresessen oder andere Veranstaltungen zu organisieren, schaut doch mal bei unserem Team Festivities vorbei! Alle Sitzungstermine findet ihr hier: https://agdsn.de/sipa/meetingcal . Bei Fragen wendet euch gerne an du-bist-gefragt@agdsn.de .

Outage Borsbergstraße 34, Neuberinstraße 15

On 2024-06-03 13:14:57 road work caused damage to the fibre optic cable to Borsbergstraße 34. Therefore, network access failed for Borsbergstraße 34 as well as Neuberinstraße 15. The latter is affected due to Borsbergstraße 34 being the sole provider for it's network.

In order to restore network access, a radio link between Wundtstraße 3 and Borsbergstraße 34 has been installed on Monday evening until the early hours of Tuesday. Due to a configuration mistake, access couldn't be recovered until late Tuesday evening.

Unfortunately, there is huge decrease in bandwidth paired with a strong increase in latency. We as well as the Studentenwerk are working intensively to reach an improvement of the situation.

The office hours on May 9th, 2024 will be canceled due to the public holiday. There will also be no telephone support during this time.

If you have any problems, you can of course still use our contact form.

As we currently do not have enough volunteers, there are only limited office hours.
Do you want to change that? Then come along to a team meeting of the Office and Support Team (BuS) - or to one of the future office hours. (You don’t need a technical background to help other members…)

April at AG DSN

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.

Want to contribute to the student network yourself? Visit us at one of our team meetings! In case you have questions, reach out to us via email to du-bist-gefragt@agdsn.de.

Change of our wifi access data

WiFi Internationales Gästehaus
Written by Markus Ziehe, 2023-09-16. Permalink 

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.
