This is how to log out of DICE if you are using the MATE desktop environment. (If you have not chosen a different window manager then your window manager will be MATE.)
First, click the "cog wheel" logo at the top-right of the screen. A menu will appear:
Select the Log Out.. item. A new window will now appear in the centre of the screen which will ask you to confirm that you wish to logout:
This page describes how the systems at the various Informatics sites will react to power outages.
This page summarises the network connectivity used between Informatics sites, to the rest of the University, and to the rest of the Internet.
Informatics operates a unified network across four sites: the Forum, Bayes Building, Appleton Tower and JCMB.
All University-owned desktops and laptops - including self-managed - should be encrypted.
The disks on University-managed Windows and Macs are encrypted.
For DICE desktops see Encrypting Groups of Files on DICE. Some DICE disk partitions are encrypted, and the computing staff are working on encryption solutions for the others.
If you don't know which VPN to use, then use the University VPN.
evince is the default PDF viewer on DICE.
Annotation works on Ubuntu but is not supported on SL7.
For full guidance on how to use evince, see:
google-chrome displays PDF well.
A window manager controls the placement and appearance of windows on your screen.
When using the ⇒ DICE remote desktop you use a window manager called MATE. This can't be changed. But when you use a DICE computer directly - actually sitting in front of one - you have a choice of window managers.
How to try another window manager once
You may get this error from the ssh command:
kex_exchange_identification: read: Connection reset by peer
Or it might look like this:
ssh_exchange_identification: read: Connection reset by peer
These are the most likely reasons for the error:
The Google Play Store for Android devices (largely tablets and phones) offers a massive choice of SSH apps which provide an SSH client and terminal emulator combined, allowing your device to login to Informatics machines. Popular ones include JuiceSSH, Termius and ConnectBot but there are dozens available, many for free.
If you work from home, you might find that your ssh sessions to the Informatics ssh servers unexpectedly time out. If so, the problem is almost certainly being caused by your home NAT router timing out what it considers to be an 'inactive' session.
The solution is to use 'ssh keepalives' - to configure your ssh client to automatically send some 'no-op' protocol codes to the server every now and again, in order that the NAT router considers the session to be active.
How to configure this will vary from OS to OS.
