Connection Setup

  • As host name or IP address (possibly also referred to as »Rechnername« or »Server«), enter e.g. gonzo.uni-weimar.de (or another server on which you have a log-in).
    • Enter your login name as the user name (or »Benutzername«).
      (usually the user name of your university account)
      • As Password (or »Passwort« / »Kennwort«) you enter your password
        (usually the password of your university account)

Notice about possible connection problems

If you cannot establish a connection, it may be because you have saved an outdated, invalid host key. Look for this key in the Settings/Preferences area in the program you are using and delete it.
When you reconnect, the key is created again and you can log in and establish an encrypted connection.
