Remote access
There are several ways to connect to the department's computers, all of which require you to have a working account (see Account) .
SSH with Unix
If you are using a Unix computer and have a shell available, use one of the following commands to log into one of our two ssh servers:
ssh username@ssh.math.uni-bielefeld.de
ssh username@ssh2.math.uni-bielefeld.de
(and confirm any security question with "yes"). From ssh or ssh2 you can then access the computer you wish with ssh again.
Blocked after using a wrong password
After having used three times a wrong password, access to the server concerned will be blocked from your IP address. As a workaround, you can still switch to the other server. To unblock the IP address, write to root, telling us which IP address you have been using, or exactly at what time the blocking occurred.
SSH with Windows
For Windows there is an easy to installing program called PuTTY. To download it, click on one of the following links:
Further documentation to PuTTY can be found on the PuTTY Homepage.
Using SSH without password
When logging in with the internal password, you are granted a Kerberos ticket, with the help of which you can connect to any other computer of the faculty without having to enter a password again. However, if you log into the remote servers with ssh keys (without entering a password), or with the external password, no Kerberos ticket will be granted. In this case, you may request a Kerberos ticket with the command kinit, which asks for your internal password. A ticket created in this way is valid at most until the next reboot of the server.
