-===== 2019-01-29: Scanning from the multifunction device "feder" in the BYOD room (U1.040) =====
+===== 2023-08-07: Change  of WiFi Certificate of C.S.dept. and B-IT =====
-It is now possible to scan from "feder" not only onto a USB storage device, but also into an E-mail. You have to
+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).
-login first, using the display of "feder" ("Alternate Login").
-Please don't forget to log out afterwards.
-----
+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.
-===== 2018-10-04: Change Account Registration and Extension =====
+You will find the current [[en:wifistd|fingerprints and certificate downloads]] at the usual place.
-The creation and extension of accounts became 02.10.2018. converted to a new graphical system. It is used as an alternative to the well-known text terminal.
+The VPN service is *not* affected by these changes.\\
-Accounts and extensions in the main subject require a valid s6xxxxxx@uni-bonn.de mail address (or s5 .., s4 .., ...). Please take care to avoid umlauts (ä, ö, ü, ß) when renewing or renewing the application. The password must consist of the following components:
+\\
-   - At least one capital letter (A, B, C, ...)
+----
-   - At least one lowercase letter (a, b, c, ...)
+=====2023-07-14: Configuration change also for "eduroam-cs"=====
-   - At least one number (0, 1, 2, ...)
-   - At least one special character (except '*')
-   - At least 10 characters long
-Account extensions are usually in the period 01.11.-30.11. possible. Please note the warning via e-mail.
+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]].
-For questions, problems or errors please contact the GSG (room 0.014 / 0.009).
+According to HRZ, a connection with the old parameters **won't be possible after July 15th, 2023**.

-===== 2018-09-14: Maintenance WiFi Networks =====
+===== 2023-07-10: Student printer (feder) malfunctioning =====
-Due to the continued problems with our core router, we are trying to take some load away from it by changing the routing configuration of our WiFi Networks to other components. Because of that you can expect some outages of the wifi throughout the day.
+**Update:** The parts have been changed.
+The student printer in U1.040 (feder) is malfunctioning. We already identified the problem and replacement parts have been ordered. They shall arrive by 12th July 2023. Until then we ask for your patience.\\

-===== 2018-09-05: Status of the core network routing problem =====
+===== 2023-02-02: Wifi services unavailable =====
-We just experienced another network outage, which was intended this time to collect data for the problem analysis of the hardware vendor. We continue to work on a solution, utilizing our support contractor and the hardware vendor.
+**UPDATE (09:40h) : all wifi services are fully restored by now.**
-By now we punched down the possible suspects to the IPv6 core of the router, which now remains disabled to ensure a stable IPv4 operation.
+We are currently experiencing a total loss of WiFi authentication
+inside the whole building of the Computer Science Dept. and the B-IT due
+to a failure of a central component.
-We thank you all four your continuous patience and support.
+We are already working on a solution to the problem. Unfortunately we
+cannot predict how long these repairs will take. Due to the nature of
+the problem, it could be a longer process.
+Other services are not affected by the disruption.\\
+\\
 ----
+===== 2023-01-30: New transponder forms =====
-===== 2018-09-03: Further problems with our central network routing components =====
+There are new versions (V9) of all transponder forms available (German only). If you have saved the forms locally, please replace them with the current versions. You can find those as usual on our homepage:  [[ de:transponder | Transponder ]]\\
+\\
-As the recent proceedings in patching up our central routers were not successful, we are continuing to experience massive problems with our core network, resulting in massive performance issues and complete blackouts of network connectivity. This problem is of a non-trivial nature, we are continuing to investigate the issue, utilizing our support partners and the hardware vendor itself.
-At the moment we seem to have pinned down the problem to the IPv6 core of the router. To stabilize the situation as good as possible, we have disabled IPv6 routing for the time being, hoping to reactivate it after resolving the problem.
-Please continue to be patient and remember that the whole setup in this building is completely new, some problems simply were to be expected.

+===== 2022-09-19: Poster printouts unavailable at the moment =====
-===== 2018-08-31: Maintenance window of central network routing components =====
+We are unable to print your posters at the moment due to defective hardware in our poster plotter. Please utilize the similar service from the  [[https://www.hrz.uni-bonn.de/en/all-services/print-scan/poster-printing?set_language=en|University IT and Data Center]].\\
+\\
-In the time between 7:30 a.m. and 9:00 a.m. we will update the central routing components. As a direct result there will be total network service outages during this period in the whole c.s. dept. and the b-it. We apologize for the inconvenience.
+**Update (2022-10-05):** the plotter has been repaired, we resumed to provide our plotting services.\\
+\\

-===== 2018-08-28: Outage of network connectivity =====
+===== 2022-09-15: Availability of Pool PCs during nighttime =====
-We just experienced a breakdown of the central routing components of the c.s. dept and b-it. the problem was corrected and we are investigating the cause.
-Thank you for your patience.
+In order to reduce power consumption, the publicly accessible Pool PCs are automatically shut down over night, from 8 p.m. CEST to 8 a.m. CEST.\\
+More information can be found on the [[https://gsg.cs.uni-bonn.de/doku.php?id=en:pool:remoteaccess#availability_at_night|Pool remote access page]].

+===== 2022-07-19: WiFi Certificate about to expire, replacement imminent =====
-===== Commissioning the new print account =====
+**UPDATE 2022-07-25:** the certificate was successfully replaced.
-The printing system known from the Römerstraße is online in a revised version since Monday, 06.08.2018. Further information can be found in the tab "[[en:print | Print Services]]".
+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.
+\\

+===== 2022-07-15: E-Mail service computer science & b-it unavailable =====
-===== Guest WiFi available for Workshops and conferences etc. =====
+**Update: The e-mail-service is restored.**\\
+The email addresses @informatik, @cs and @bit are affected. The problem is being worked on.
-For any sort of special event or just for short-time guests we are now offering temporary access to our WiFi infrastructure through a sponsored [[en:guestaccounts|guest portal system]]. If you are hosting an such event or awaiting guests, please [[mailto:gsg@informatik.uni-bonn.de|contact us]] for further information.

+===== 2022-03-03: new Chat-Function on GSG-Supportpages =====
-Please be patient, we will announce the end of the works here.
+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).
