+===== 2023-08-07: Change  of WiFi Certificate of C.S.dept. and B-IT =====
-  *  BigBlueButton Load Balancer (bbb.informatik.uni-bonn.de)
+Today we did renew the certificate for our wifi infrastructure. At the same time we switched over to the new certification authority hosted by the DFN (GEANT, just like the HRZ did some days before, you may remember the mail about eduroam).
-  *  a central file server of the B-IT
-as well as the machines
+This means that all wifi configurations of your devices that are used to
+connect to the computer science dept. or the b-it (eduroam-cs and
+.1X) have to be reconfigured to check for the new certificate/and
+or CA.
-  * vm-wuebbel-01
+You will find the current [[en:wifistd|fingerprints and certificate downloads]] at the usual place.
-  * sentry
-  * mail-info4
-  * bbb4mm
-  * leonov
-  * inf1-srv-01
-  * login.bit.uni-bonn.de
-The affected systems are immediately shut down completely in order to accelerate the repair of the affected storage backend. After repairs have been completed, the systems will be moved to a newer cluster in the short to medium term.
+The VPN service is *not* affected by these changes.\\
+\\
+----
+=====2023-07-14: Configuration change also for "eduroam-cs"=====
-The central BigBlueButton IT service is also affected, the individual BBB servers are available (ongoing conferences are not affected), but new rooms cannot be opened or existing ones can be entered. I hope to be able to use the load balancer again tomorrow at the latest.
+The [[https://www.hrz.uni-bonn.de/en/news/reinstall-eduroam-on-all-end-devices-by-15-july-2023|configuration change/re-installation of Eduroam for members of Bonn University]] is also necessary for the Eduroam branch in our building (eduroam-cs). The updated configuration parameters are [[en:eduroam|available on our Web page]].
-I apologize for the inconvenience, we are working on eliminating the problem.
+According to HRZ, a connection with the old parameters **won't be possible after July 15th, 2023**.
+If you have an Informatics/B-IT account issued by us, you can (and should preferably) use the network _802.1X_ in our building. [[en:wifistd|Here are the usage instructions.]]\\

-More Informations about this [[en:overleaf|can be found here]]...
+As the current certificate used for our wifi authentication services is about to
+expire, we will be updating to a new certificate soon. Your operating system could
+be set up to notify you about this for security reasons. If this happens, you can
+safely accept the new certificate and make sure it is the right one by comparing
+the certificate fingerprints to the ones issued on our [[en:wifistd|wifi documentation]] page.

+===== 2022-03-03: new Chat-Function on GSG-Supportpages =====
+As we are trying to further accomodate incoming support requests especially from students, we added a new chat function to this page to give you an opportunity to request aid directly from us without the need for a physical helpdesk. If this service is maintainable, we will try to implement it into other central services (like i.e. WUMI).
+If you want to use the chat, just click on the blue bar on the bottom right part of the page footer.\\
