Here are some important recent changes CSG have made to our services:
- We have upgraded the Departmental gitlab server (gitlab.doc.ic.ac.uk) from version 8.11.11 to version 9.5.5, nearly the latest version.
- We have refreshed timetable.doc.ic.ac.uk with updated 2017-1018 data for the start of term, and we have worked with the Dept Timetabling Officer (Damian Cerase) on improving the quality of the timetable data.
- The "student database server" db.doc.ic.ac.uk has been upgraded from PostgreSQL version 9.2 to 9.6.
- The lab layout has been revised with approximately 80 computers in Huxley 206 and 219 replaced. Room 210's primary purpose has changed, after extensive discussions, the Teaching Operations Committee decided that Huxley 210 is now the QUIET LAB and contains 41 general-purpose computers, and can now be occasionally booked for lab sessions. The Graphics workstations that used to be in 210 have been split: graphics 1 to 12 are now back in 219 in the central ring, the remaining 18 machines will be racked up in our machine room shortly and accessible only via ssh. We'll announce this later.
- We have released termly Ubuntu Linux package updates to CSG-supported Ubuntu 16.04 and 14.04. If your machine is not running Ubuntu 16.04, and you'd like it upgraded (or replaced), please let us know - email email@example.com telling us the name of the machine, where it is, which OS it's running at present, and whether or not there's any important non-backed up data on the local hard disk, and we'll arrange Linux upgrades or machine replacements.
- Continuing our active desktop PC retirement policy for PCs older than 4 years old, we have decided to start retiring HP Elite 8300 PCs (and anything earlier, naturally, eg Dell Optiplexes, HP 8200, 8100, 8000, 7900 etc). Please let us know if you think your desktop PC should be replaced, and we will discuss it with you and make suitable arrangements. As ever, please email firstname.lastname@example.org with the details.
- We have added a new "Activities" section to the CSG website, showing entertaining InfoGraphics views of CSG regular activities through the year. Hopefully this will show you some of what goes on behind the scenes in CSG.
- We have started working through remaining Ubuntu 12.04 computers in the Dept, as Ubuntu 12.04 is soon to go out on maintenance, offering to retire or replace or upgrade old machines. We've retired all such desktop PCs, but various servers remain.
- We have also started to actively retire desktop PCs over 4 years old, especially HP Elite 8200 desktop PCs (and anything older). If you think you have a machine older than 4 years old, please email us on email@example.com giving us some useful details, and we'll see whether it could be replaced or retired.
- We have upgraded the Departmental gitlab server (gitlab.doc.ic.ac.uk) from version 8.10.0rc4 to 8.11.11 (we had intended to upgrade it considerably further, but experienced some unexpected difficulties).
- We have refreshed timetable.doc.ic.ac.uk with updated Spring Term data for the start of term.
- We have released termly Ubuntu Linux package updates to CSG-supported Ubuntu 16.04, 14.04 and 12.04. If your machine is not running Ubuntu 16.04, and you'd like it upgraded (or replaced), please let us know - email firstname.lastname@example.org telling us the name of the machine, where it is, which OS it's running at present, and whether or not there's any important non-backed up data on the local hard disk, and we'll arrange Linux upgrades or machine replacements.
- Ubuntu v16.04 , Non-CSG maintained Cloud VM templates have been made available.
- These new templates no longer require a reboot for intialisation.
- Any additional storage added during VM deployment would be automatically mounted as /data.
- /boot is no longer a separate partition.
- The departmental Linux home directory servers have been updated from Ubuntu 12.04 to Ubuntu 16.04.
- The hardware and operating systems underlying key departmental Linux servers has been updated. This should lead to faster, more reliable services for our end-users and increased expansion options.
- The teaching labs - Huxley 202, 206, 210 and 219 - have been overhauled for the new academic year.
- We have upgraded our main web servers www.doc.ic.ac.uk and wwwhomes.doc.ic.ac.uk to new Ubuntu 14.04 machines runnig Apache2 2.4.7 with our local suexec changes.
- These new servers achieve SSL Labs coveted A+ SSL security rating.
- If you find that any of your CGI scripts no longer work, please ask us to check via emailing email@example.com.
- The old Ubuntu 12.04 based webservers are still around as www-old.doc.ic.ac.uk and wwwhomes-old.doc.ic.ac.uk, for the rest of the Summer term. After that, they will be decommissioned.
- We have released packages to fix an important Gnu C Library (CERT CVE-2015-7547) to all supported Ubuntu 12.04 and 14.04 hosts.
- We have retired/reinstalled all older vulnerable Ubuntu desktops that we know of (eg those running Ubuntu 11.04 or 13.04). If you think your Linux desktop/laptop may be vulnerable, ask us to check via emailing firstname.lastname@example.org.
- The DoC GitLab service has been upgraded from version 7.14 to 8.3.4. The new 8.x version includes the GitLab Continuous Integration functionality. CSG is working on developing a vm template to use as a test runner with DoC GitLab CI. We will inform you as we make progress.
- The DoC Ubuntu versions 12.04 and 14.04 have been updated.
- Following requests in our recent user survey for more quota, we decided to double all new users' DoC home directory quota from 4GB to 8GB.
- Of course, we also raised the home directory quota of all existing users with less than 8GB to 8GB.
- The GanttProject software package has been set to deploy on all DoC Ubuntu 14.04 desktop computers.
- Minor version upgrade of the DoC Private IaaS CloudStack management Interface from 4.5.1 to 4.5.2
- A new document has been provided for deploying a VM
- Mailing group for DoC Cloud users has been setup: email@example.com
- Major version upgrade of the DoC Private IaaS CloudStack management Interface from 220.127.116.11->4.4.1->4.4.2->4.5.1.
- Updated the VM image templates to include fail2ban and sshguard along with the latest kernel updates. Users deploying 'Non CSG' maintained templates now have access to their ICT home directories which are 8Gb and are backed up.
- 90% of the VMs have been updated to the latest kernel and rebooted to reflect it.
- The old batch server Tui, alias batch1, has been retired. batch1 is now an alias for Potoo01 and batch2 is now an alias for Potoo02.
