There are several ways to connect to the department's computers, all of which require you to have a working account (see Account) .
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 (and confirm any security question with "yes"). From ssh or ssh2 you can then access the computer you wish with ssh again. This can be done also in a single step (on one line):
ssh username@ssh2.math.uni-bielefeld.dessh username@ssh.math.uni-bielefeld.de -t ssh favorite-computer
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.
With the Public-Key-Method, an RSA-authentification, SSH offers a way of accessing a computer without having to enter a password. For more information, see the man page: man ssh
A key is generated using the following command: ssh-keygen -t rsa Now you can enter an arbitrary password, or just hit Enter. In the latter case you won't be asked to enter a password. Then change directory by typing: cd ~/.ssh Now you can add your new key to the "authorized keys": cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys For remote access you have to insert the locally generated public key into the file $HOME/.ssh/authorized_keys of the remote computer you wish to access. This can be done via: ssh-copy-id -i ~/.ssh/id_rsa.pub username@remote-host Make sure nobody gets access to your private key (id_rsa).
