How can I connect to the SfS server from my home computer?

You can connect to the SfS server ( not only via the computers at the SfS, but also remotely over the Internet. This is a prerequisite for accessing your SfS e-mail account, your home folder, certain applications and resources provided by lecturers.

In order to connect to Urobe, you need to be within the university network. This is automatically the case if you

  • are working on any computer of the university
  • are using the Internet connection of a dormitory which uses the university network.

Otherwise, you need to connect to the university network using a VPN connection. Setting this up is a bit complex, so there is a page of its own for it: VPN.

Urobe, Penthesilea? Who are they, what do they do?

Back in its old days, the SfS was using computing technology by Sun Microsystems. This technology was running Solaris as Operation System on special hardware. Hence, the server was also running this system and they decided to call it Penthesilea. It did a lot of jobs, including being the e-mail server and the server for people to login from outside the SfS network and thus also the machine on which one could run programs remotely from home.

Penthesilea grew a beard and the beard became gray, so it was obvious that it needed a successor. This successor now is Urobe and it runs Linux. It is hosting the (new) mailboxes and it is there for you to login from the outside. On Urobe, you should have everything you have on the pool machine – excluding screen and keyboard.

At the time of writing (2008-11-18), there are quite some mailboxes still living on Penthesilea. Both machines can be accessed from the University Network only (use VPN from home!).

How can I connect to the wireless Internet inside the University with my own Notebook?

Please read the howto on using VPN.

Why can't I send e-mail from within the university network?

By default, e-mail clients send mail to port 25 of an SMTP server - such as if you're using WEB.DE with an e-mail client (as opposed to using the Web interface). This port is blocked by the university network in order to make it harder to send spam. Two solutions exist:

  1. Tell your e-mail client to always use for sending e-mail. There is no problem in principle with using an SMTP server that doesn't "match" your sender address. However, for certain domains, certain spam filters may not like this. (In particular if the domain of your sender address is administered by someone who thinks SPF is a good idea.) Thus, this solution slightly increases your risk to end up in your recipient's spam folder.
  2. Many SMTP servers allow using port 587 instead of 25, and port 587 is not blocked by the university. Some e-mail clients, such as Thunderbird, have a separate option to specify the port. Others, like Evolution, accept appending a colon and the port number to the name of the SMTP server - like this:

I don't find my question answered here. What do I do now?

You can ask students of Allgemeine Sprachwissenschaft (general linguistics) and ISCL in the Fachschaft Forum. ISCL students are kindly asked to join the students mailing list and post their questions there. For the innocent: Wikipedia epxlains how mailing lists work.
