-===== 2020-10-17: Maintenance Window for the Network Infrastructure of the Serverrooms of C.S. Dept and B-IT =====+===== 2023-12-12/13: TVS maintenance window =====
  
-At Saturday, the 17th of October 2020, beginning at 10:00 and lasting up to 17:00, the complete network infrastructure of the serverrooms of both the c.s. dept and the B-IT will be down for software upgrades. This will affect the whole IT-infrastructure of both institutes.+<html><div class="tpl_update">The tutorial assignment system is operational again.</div> 
 +</html>
  
----- +This semester's data will be available until end of semester.
-===== 2020-09-28: The Aftermath of a Power Outage =====+
  
-Due to a power outage in the early morning, there were massive connectivity problems throughout the university networks.  +<del>TVS will not be available on 12th and possibly 13rd of December //from 10am to 12pm,// while doing a software update. 
- +If you still need your data, please read them out before. This will also be possible afterwards, of course, </del>\\ 
-In the computer science dept., all systems without direct UPS-support were affected, but these problems should all be fixed by now. +\\
- +
----- +
-===== 2020-09-22: Changes for wireless networks CP1GUEST and EDUROAM-CS ===== +
-Due to routing changes of the abovementioned networks, we anticipate a few discontinuities for them. If you have a CS/B-IT account, we remind you that you should better use [[en:wifistd|our internal network ''802.1X'']] (which most likely won't be affected this time). +
-//Update:// The activities have been terminated for the time being. +
----- +
-===== 2020-09-17: Maintainance of Internet Connection: finished  ===== +
-Due to maintainance of the Internet connection, individual services might be disconnected for a short time today. Normally, you can reconnect right away.+
 ---- ----
-===== 2020-09-01: New Service: Matrix IM  ===== +===== 2023-08-07: Change  of WiFi Certificate of C.S.dept. and B-IT =====
-We just finished the deployment of a node of the matrix.org instant communication network. More info can be found [[en:xmpp|here]].+
  
----- +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).
-===== 2020-08-17: Maintainance of Account server  ===== +
-The maintainance of the account creation and renewal website, startup, is finished. +
----- +
-===== 2020-08-10: DNS Resolving last Weekend  =====+
  
-From sunday, ~13:00 up to today, ~9:30, we experienced minor problems throughout the entire network of the c.s. dept and the B-IT due to a failing primary nameserver. The problem was corrected by now.+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 
 +802.1X) have to be reconfigured to check for the new certificate/and 
 +or CA.
  
----- +You will find the current [[en:wifistd|fingerprints and certificate downloads]] at the usual place.
-===== 2020-05-03: Mailservice temporarily down ===== +
- +
-Due to failed network equipment in the HRZ the mail server is offline at the moment. Please be patient while the problem is solved. +
- +
-UPDATE: the problem has been solved, the mail service is available again.+
  
 +The VPN service is *not* affected by these changes.\\

-===== 2020-04-24: Discontinuation of OSP Videostreaming =====+=====2023-07-14: Configuration change also for "eduroam-cs"=====
  
-Due to massive problems with the software Backend, we had to shut down our streaming services on the OSP server permantly.+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]].
  
 +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.]]\\

-===== 2020-03-18: Reduction in attendance times due to COVID-19 =====+===== 2023-07-10: Student printer (feder) malfunctioning =====
  
-Due to the special situation we find ourselves in these days, we decided to reduce our attendance service to the absolute minimum possible for the foreseeable time. Further information is available [[en:covid-19|here]].+**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.\\

-===== 2020-03-05: Availability of the Computer Pool Rooms U1.012, U1.041, U1.042 =====+===== 2023-02-02: Wifi services unavailable =====
  
-After the end of the [[https://www.informatik.uni-bonn.de/de/Pressemitteilungen/schueler-krypto-botschaften-verschluesseln-im-auftrag-ihrer-majestaet?set_language=en|Schüler-Krypto 2020]], the above mentioned pool rooms and the computers in there have been returned to their regular use.+**UPDATE (09:40h) : all wifi services are fully restored by now.**
  
----- +We are currently experiencing a total loss of WiFi authentication 
-===== 2019-06-25: Update Status Imagine Premium/Microsoft Azure Dev Tools =====+inside the whole building of the Computer Science Dept. and the B-IT due 
 +to a failure of a central component. 
  
-By now a registration using the university email address is possible. More information available on [[en:microsoftimagine|this page]].+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.\\
 +\\
 ---- ----
-===== 2019-06-25: Status Imagine Premium/Microsoft Azure Dev Tools ===== +===== 2023-01-30: New transponder forms =====
- +
-Since Microsoft changed the name of the program from "Imagine Premium" to "Azure Dev Tools for Teaching", they changed the requirements for registration to the program portal, too. As for now, an institute email address is required for registration. As newer students are not longer provided with one of these, only older students with an old address are able to register. Microsoft is working on a solution to this problem, but as for now, there is no workaround. So we cannot provide you with access to the program at the time-being.+
  
 +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 ]]\\

-====== 2019-06-24: Loss of central Storage at B-IT ======+===== 2022-09-19: Poster printouts unavailable at the moment =====
  
-Last Friday around noon we experienced a total loss of several central components of our userstorage for UNIX (NFS) and Windows (SMB). Sadly we had to realize that we lost a rather important large storage component completely, so we had to recover the affected storage areas from our backup to alternative server systems. Because of that, a certain loss of data in the confines of the regular backup schedule (usually daily in the night) has to be expected. +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]].\\
- +
-The data rescue operation is completed by now, all services were restored again. +
- +
----- +
-===== 2019-05-29: New Host Keys login.bit ===== +
- +
-The SSH Login Server of the b-it was reinstalled and received new host keys. If you want to verify, please refer to the following fingerprints: +

-===== 2019-05-20: eduroam, eduroam-cs and the new certificate ===== +===== 2022-09-15: Availability of Pool PCs during nighttime =====
-Until the replacement of the eduroam-cs certificate within IT, the certificate specified [[en:eduroam|here]] must still be used when connecting to eduroam-cs! We will have completed the conversion to the new CA within the next few days, so you can also use the new certificate within eduroam-cs, as stated in the HRZ newsletter. We will announce this accordingly here.+
  
 +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]].

-===== 2019-04-29: No Audio available in Room 0.107 =====+===== 2022-07-19: WiFi Certificate about to expire, replacement imminent =====  
  
-Because of a device defect, there is currently no audio available in room 0.107. Please bring your own speakers or contact GSG for alternatives. We hope that the replacement amplifier will be installed during week 19.+**UPDATE 2022-07-25:** the certificate was successfully replaced. 
 + 
 +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.

-===== 2019-04-12 10:00: DNS resolver 131.220.51.34 has been switched off ===== +===== 2022-04-05: Authentication Problems with Matrix Service =====  
- +
-The DNS resolver 131.220.51.34 had been replaced by +
- +
-131.220.4.11 +
-131.220.4.17 +
-2a00:5ba0:10:330::b +
-2a00:5ba0:10:330::11 +
- +
-a few weeks ago and has been turned off on Friday, April 12th, 2019, 10:00 local time. +
- +
-(We will return our temporary network 131.220.50.0/23 to the University +
-Computing Center shortly.) +
-  +
-Most machines (computers, printers, scanners, etc.) are configured by DHCP +
-automatically and have switched already, We have told about others, that we +
-had detected, to the colleagues in the work groups that manage them. +
- +
-Should there still be machines that are manually configured to use +
-131.220.51.34 by the users themselves: you have to change the DNS resolver +
-setting to the values shown above. However, as far as we can see, +
-there are only a few left, that are already known to their +
-administration. So the only problematic machines are such that were +
-switched off for the last few days.+
  
 +After the last Update of the matrix Service, some users may have experienced problems logging into out matrix service. This problem is now fixed. Existing sessions were not affected by this problem.\\

- +===== 2022-03-03: new Chat-Function on GSG-Supportpages =====   
-===== 2019-01-29: Scanning from the multifunction device "feder" in the BYOD room (U1.040) ===== +   
- +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).   
-It is now possible to scan from "feder" not only onto a USB storage device, but also into an E-mail. You have to  +   
-login first, using the display of "feder" ("Alternate Login").  +If you want to use the chat, just click on the blue bar on the bottom right part of the page footer.\\
-Please don't forget to log out afterwards. +
