These sites are hosted, managed and supported by C&CZ. All content management tasks are performed by the respective web site owners: institutes and scientific departments, student organisations, service departments, etc. Please contact C&CZ for more information about WWW_Services....

As a test of the new version of Ubuntu, 22.04 LTS, we have installed a new login server lilo8.science.ru.nl. In a few months it will replace the four year old login server lilo6. The name lilo, that always points to the newest/fastest login server, will then be moved from the two year old lilo7 to the new lilo8. The new lilo8 is a Dell PowerEdge R6515 with 1 AMD 7502P 2....

FNWI asks lecturers and students to fill in a survey about the computer labs. The reason is that the Faculty of Science plans to remodel its teaching rooms in a multifunctional way, with computer labs that use ‘Bring Your Own Device’ (BYOD). This means that the existing computer labs (terminal rooms, TK’s) in the Huygens building will be phased out in the coming years. In order to plan the further implementation, we would like to request your input on the current use of the computer labs by means of a survey in order to determine the pace and which alternatives may be needed to replace the various current uses of the current computer labs....

February 14, ILS switched off antique versions of TLS (1.0 and 1.1) for the Eduroam authentication on ILS LDAP servers. From then on, SUSE Linux 15.3 clients can’t authenticate with U- or s-number. They only have TLS1.2 and the ILS servers offer TLS1.3 first, after that an error occurs. By using the Science-account to authenticate, these users succeed in connecting to Eduroam.
