In November 2014 the remaining end user vestiges of the legacy school database service originating in 1996 were migrated into Theon. The areas and workflows that were transitioned at this time were: Staff Records Visitor Records Post Application Visit Day handling for UG students Taught PG student admissions handling The School InfHR team were moved across […]
In order to maintain the integrity of our systems we need to reboot all DICE desktops over the next few days. We understand that reboots can be very inconvenient so you can be assured that we will only ever schedule reboots which we consider to be essential. A delayed reboot has been scheduled for all […]
As described in my November posting, we’re making some changes to our OpenVPN configuration, partly to support new devices, partly to add capacity, and partly because one of the features we currently use is being phased out. The server-end changes are now all in place, as are the new configuration files needed on the client […]
When the Forum meeting rooms were set up, we configured the wired network in them to use the “office self-managed DHCP” subnet. This seemed appropriate at the time, as most users were expected to be Forum occupants. The ground-floor meeting areas, in contrast, were set up to use a separate “conferences” subnet, outside the Informatics […]

We have now resolved the hardware problems with the new hardware for the staff NX server so we can reschedule the planned upgrade. On Tuesday 6th January we plan to replace the staff NX server named central which hosts staff.nx.inf.ed.ac.uk with a machine named northern. All that will happen is that at about 09:00 on […]
We have recently discovered a problem with the cron daemon (cronie) which is supplied with SL6 and SL7 which means that users with home directories stored in AFS have been prevented from using the service on DICE machines. We have now patched the code and are satisfied that normal service has now been resumed. This […]
Earlier this year we conducted a survey of VM/cloud usage. The project has now concluded and a formal report on the project can be found on the Rat Unit wiki This includes a link to the survey report itself. Copies of all the documentation relating to the project can be found in afs in the […]
It’s now over ten years since we first set up our OpenVPN service, and things have moved on quite a bit since then. So far we have managed to maintain compatibility for existing users of the service, but we would now like to make a couple of enhancements which unfortunately do require incompatible changes: We […]
