As the likes of homepages.inf.ed.ac.uk and groups.inf.ed.ac.uk are shared user services, anyone using some sort of authentication/authorisation to restrict access, has to trust the other users of those web services. A lot of the web’s security model relies on the “same origin policy”. * https://en.wikipedia.org/wiki/Same-origin_policy which limits the access scripts have to data (particularly authentication […]
We’re changing the *.remote.inf.ed.ac.uk Remote Desktop service to remove some of the machines. However, everybody will still be able to use the service as before. Back in the spring, we made ten machines available for remote desktop sessions under the name UUN.remote.inf.ed.ac.uk where UUN is your University username. (For instance, my username is cc so […]
Users of AFS on MacOS may be mildly perturbed to find out that the MacOS AFS client has until recently contained a couple of critical bugs which could result in permanent loss of data if triggered. For this reason, we are advising all MacOS AFS users to update to the latest version of the AFS […]
Prior to lockdown we only had a single “staff” server and a single “student” server but with the need to provide adequate facilities to allow working from home, we had to expand our provision. Based on the work of FreeRDP and rdesktop, xrdp uses the remote desktop protocol to present a GUI to the user. […]
Just before the shutdown we replaced some lab machines with desktops with lower spec GPUs These are elitedesk 800 g4s with gtx 1060 cards which can be used for development work and for short or small scale processing. Please do not run long jobs on them or your jobs will be killed. Physically the machines […]
If you don’t use any servers in either of the Forum self-managed server rooms, then please ignore this blog post – and have a nice day! However, if you do use any such machines, then it is important that you read the following, and fully understand the situation concerning power to those machines. We are […]
As we prepare to enable IPv6 on the “static self-managed” wires, there are a few aspects to IPv6 addressing which you need to know. The most obvious difference between IPv4 and IPv6 addresses is that the latter are 128 bits log. They’re conventionally divided up into eight 16-bit chunks, written in hex and separated by […]
Following the introduction of IPv6 for the Forum self-managed dynamic-address subnet (and the ironing out of a couple of teething problems), we would now like to roll IPv6 out to the two “static-self-managed” subnets (“SM164” and “SM197”). We propose enabling this on Monday 10th February, at lunch-time. To do this we will set up the […]
It’s now more than three years since we implemented IPv6 for the School’s managed Linux (DICE) desktops and servers, and in that time we have seen very few issues which were specifically related to IPv6. We were not, unfortunately, able to roll it out to the “self-managed” subnets at that time, for a few reasons, […]
In order to minimise the risk to computing facilities during the strike action there will be a ‘change freeze’ for those computing systems managed by the School’s computing staff: the University’s Information Services are implementing a similar ‘change freeze’. This ‘change freeze’ is being extended to cover the online class exams on Thursday 5th, Friday […]
