OpenVPN DNS alternatives

The "Informatics-InfNets-Forum" and "Informatics-EdLAN-Forum" configuration files and the corresponding -AT versions tunnel only Informatics traffic and EdLAN traffic respectively, leaving all your other traffic to go out through your ISP's default route.

We normally recommend those, as they're generally more efficient and robust, but they do have the potential issue that traffic to other sites will have your ISP-provided address, and so anyone basing authorization decisions on that address won't see you as being a University person. "Informatics-AllNets-Forum" (and ...-AT) is provided as a workaround for that situation. It tunnels all traffic over the OpenVPN tunnel, and so to the outside it appears that you have an EdLAN address. Unfortunately that does have some side-effects.

Virtual DICE support

Limited support

We can only really provide support for the most recent version of Virtual DICE. When a new version comes out, users of Virtual DICE should switch to it - being careful to rescue any files from their old VM before deleting it.

Remember that Virtual DICE is intended for fairly simple tasks. If you find yourself needing to make complex changes to it in order to support your work, please focus on DICE rather than Virtual DICE, and please ask ⇒ Computing Support for help.

How to turn off Mac "Internet Sharing"

Macs have a feature called "Internet Sharing" which lets a computer share its network connection with other devices nearby. This can be useful in the home but it causes havoc on the Informatics network, so has to be disabled.

How to disable Internet Sharing on a Mac

This should work for all recent versions of macOS, although the System Preferences window may look slightly different to the one shown here.
