To improve the resilience of the services hosted in the JCMB server room, a new Uninterruptible Power Supply (UPS) is being installed to cover the whole room. Unfortunately this work needs the power to be switched off for a period of time. That will mean shutting down servers and services. The thing that will affect […]
For many years we have used the OSPF routing protocol to exchange IPv4 and IPv6 routes with the rest of EdLAN as well as internally within Informatics. As a result of the University’s network replacement project, however, that’s going to have to change as EdLAN adopts a more layered structure. We’ll continue to use OSPF […]
For a few years now, modern browsers like Chrome, Firefox and Edge have been warning as “insecure”, web sites that are served as plain text over HTTP (port 80). Google blog article – https://blog.google/products/chrome/milestone-chrome-security-marking-http-not-secure/ Informatics are working through making all our managed websites available over encrypted HTTPS (port 443). If you run your own website […]
To use our remote desktop service, or any RDP connection to a computer at Edinburgh University, you must now (edit: from 07:00 on Wednesday 28 April) use a University VPN. If you don’t, you won’t get a connection. If you already use the University VPN or the Informatics OpenVPN, carry on – RDP should work […]
On Monday 1st March we will replace the SSH server named “bruegel” which hosts ssh.inf.ed.ac.uk and student.ssh.inf.ed.ac.uk with a new machine named “auriga“. All that will happen is that at about 09:00 on Monday we will change the DNS alias to point to the new machine. This change can take some time to propagate so […]
The BBC news website tells us (https://www.bbc.co.uk/news/uk-scotland-edinburgh-east-fife-55979665) that: “A large swathe of Edinburgh and the Scottish Borders was plunged into darkness following a power outage on Sunday night. “SP Energy Networks said about 88,000 homes experienced the power cut just after 21:00. “Households in the capital were affected, as well as properties as far south […]
We are currently experiencing significant issues with the School’s OpenAFS file system. This contains our user’s DICE home directories along with the majority of the School’s group and research data. The majority of our administrative data is now held on the University’s DataStore service and so is unaffected. This issue is not restricted to Informatics […]
[Revised & updated, Tuesday 19th January 2021] The information in this blog post is relevant to anybody who manages or uses a self-managed server located in the Informatics Forum self-managed server room IF-B.Z14. It does not relate to equipment located in the smaller Forum self-managed server room IF-B.01 – so anybody who manages or uses […]
EdLAN is increasingly embracing site-local (“RFC1918“) addresses, and as a consequence we are beginning to see services being given such addresses. (A good argument could be made that the use of such addresses implies that they should never be accessible from elsewhere, but for at least some of these services it’s not obvious that that […]
Over the next few months all those with an existing SL7 DICE desktop will be contacted by the Computing Support Team to arrange for it to be upgraded to Ubuntu 20.04 (focal fossa) . We are aiming to upgrade all staff/PhD desktops by Easter 2021, but if you would like your machine upgraded sooner you […]
