We have updated the authentication process for login server lilo7 (lilo7.science.ru.nl) as part of a test. As of now, your ~/.ssh/authorized_keys file on lilo7 is ignored. This change is designed to prevent bad actors from easily gaining persistent access. The good news is that we can now grant access to lilo7 from outside the previously very restricted IP ranges. To gain access from a new IP range, you will need to provide us with your public SSH key and the IP range you will be connecting from....
Since midnight there is a problem using Adobe Acrobat Pro DC, you are asked to activate the license. ILS is working on a solution. You can open PDFs using Adobe Reader or some other PDF reader. See: https://meldingen.ru.nl/detail.php?id=1333&lang=en&tg=0&f=0&ii for the original notice.
Just before 23:09 quite a lot of ceph storage nodes became unreachable. This seems to be due to one of the redundant links between two datacenter locations failing for about 4 seconds. This triggered a whole slew of ceph osd processes being killed off and not starting again. A generic configuration change made for all our servers generated an extra interface, which confused some of the osd processes (depending on interface ordering) when starting up....
ILS wifi management notified us that they will upgrade the software of wireless access points, because security flaws have been addressed in the latest release. The maintenance ends on 2022-10-21 01:30. Source: meldingen.ru.nl
Some time ago, some Science users fell for a phishing mail, therefore their account could be misused by spammers to send mail through our mailservers. Therefore our mailservers ended up in blacklists yesterday evening. Some mails could therefore not be delivered to other servers, that mail was returned to the sender. This morning we removed the IP addresses of our servers from several blacklists, we think that the problems are resolved now....
ILS network management announced: Tuesday September 27 23:30 maintenance is carried out on the Eduroam wireless network in FNWI buildings a.o. In most cases connectivity will be interrupted for at least 30 and at most 60 minutes.
ILS network management announced: Friday September 23 18.30 – 22.30 network maintenance is carried out on the DMZ and SRV firewalls. Connectivity interruptions of 20 to 40 seconds are expected. In case of problems, interruptions of 5 to 10 minutes might occur.
A few campus-wide dips in the power supply made network and telephony unusable for about 15 minutes, except in server rooms where UPSs guarantee the power supply. Because 7 modules of desktop switches in Huygens/HFML/Felix had become defective, several hundred network outlets will only have worked again after the relevant switch module had been replaced.
Still unclear what the cause is, several links are strongly degraded. Update: A defective switch has been replaced.
RU/ILS network management will switch to new hardware. This will lead to a network interruption of at most 5 minutes.
This afternoon three coma nodes lost their network because of an incorrect network configuration. They must have shown intermittent network problems earlier. It took us some time to find out what caused this network problem, but when found, it was easy to fix.
