After the server reboot on Monday morning, the changes to the home directories of the last two weeks had disappeared. It is still not clear how this could have happened. The backups of Saturday June 13 22:55 have been restored.
Starting a month ago, mail programs could get an update due to the vulnerability for a LogJam attack. After this update these programs refused connections with a server with a too short key. The old C&CZ authenticated SMTP server had such a short key. Users who reported this problem (with the latest versions of Pine, Thunderbird and recently also Apple Mail), were advised to temporarily use an alternative server. As of today using this alternative server is no longer necessary, because the server smtp.science.ru.nl has been replaced by a new server. ...
A short power dip interrupted desktop computers and some network switches without UPS backup power on the RU campus. It took approx. 20 minutes before the affected switches became fully operational again. A network switch at the Transitorium reported a failed module until it was reset around 8:30 am on Friday morning. For ca. 46 outlets/users the network didn’t function until 8:40. The UVB reported as cause a cable cut at the Kapittelweg. Liander reports a power disturbance an hour later at that location. ...
Resolved by a server reboot.
The server (cn99) which serviced SUN Grid Engine on Ubuntu 10.04 is no more. It could not find its disks while booting. This will not be solved because the machine is already more than five years old. Clusternodes cn67, cn74, cn75 and cn81 are influenced. They can still be used by logging into them directly.
A configuration error caused the automatic installation of an older version of GitLab (7.7.1) over the the most recent version (7.11.4). Because the GitLab version did not correspond to the state of the underlying database, what caused multiple problems. Among which the gitlab shell for ssh access and inaccessibility of some parts of the web interface. The problems were solved after upgrading to version 7.11.4.
Today the license server booted without configuring the network. The cause of the problem was an error in a configuration file. This has been corrected.
