Frequently Asked Questions: Other Services

How do I get a Mailman mailing list set up?

We need people to look after mailing lists, so they should be of the form listowner-listname@srcf.net, where listowner is either a username (like spqr2) or a society name.

Signing up for a society account solely for the purpose of running a mailing list is absolutely fine—go fill in the society application form, which lets you request mailing lists with your new account. If you want a mailing list for yourself (spqr2-listname) or an existing society, just e-mail the sysadmins.

Once the mailing list has been created, it can be managed through a web interface. Members can also configure their subscription automatically by sending appropriate emails.

How do I find documentation?

The program 'man' (short for manual) is your friend here. For example, 'man emacs' will tell you about the emacs text editor. You may also find the `info' command to be useful here—many programs with man pages also have info entries. The info system is navigated by pressing return when the cursor is over an active region and using `u' and `d' to move up and down through the hierarchy. `q' is used to quit in both programs.

Another good source of documentation, often more detailed and/or user friendly than the man page is /usr/doc/[package_name]/. The files tend to be in a variety of formats and/or compressed, so the command see is your friend here as it will (most of the time!) automatically choose the correct program to display the document.

Can you host the mail exchange or name server for my domain?

Unfortunately we are prevented from doing this by the University Computing Service.

This means that you must not point MX DNS records at the SRCF machine. If you do this then mail will be blocked as it enters the CUDN, and therefore will not reach you.

Can you install the piece of software “foo”?

Maybe - we normally only install software which is available from the latest stable release of Ubuntu GNU/Linux and which won't place excessive load on our machine. If there is something you would like to use then email sysadmins@srcf.net and we'll consider it. Details of Ubuntu packages can be found here.

Of course, if it is possible you are welcome to install things locally in your home directory. Please don't run anything which will kill the machine though, otherwise we'll come after you with sticks.

Can you upgrade “piece of software foo” to version 2046?

Unfortunately this isn't possible. We use the Ubuntu distribution of GNU/Linux and installing non-Ubuntu packages is a considerable administrative burden. When the next version of Ubuntu appears we'll be able to upgrade.

Do you run Firefox/Konqueror/Midori?

Yes, use our Desktop service for this, it currently has Firefox, Konqueror and Midori installed. On our shell server we have lynx, links and w3m (all of which are text-only browsers).
We can also install any other browser available in the Ubuntu repositories.

Can I run a server for my favourite online game?

Yes, use our game server at userservers.srcf.net. Please limit your server to 1GB of memory and set it to nice level 19 to avoid creating problems for other users. If your server is run with Java, this can be accomplished by running (for example) nice -n 19 java -Xms1024m -Xmx1024m -jar minecraft_server.jar.
