-An Xwindow terminal server containing a SSH tunneling modul (like "​StarNetSSH"​ of XWin32 or "​ConnectivitySSH"​ of Exceed) starts during SSH login process a program to create a primary Xwindow. This programm called "​xterm"​ must be found in the search path during login process. ​Unfortunately xterm is located at different places within the filesystem of the remote host and search path is often uncomplete during login process. Furthermore not all UNIX or Linux systems uses exactly the same font set. Thus GWDG creates a script usable at all login servers to call "​xterm"​ with some standard options to create a usable window (concerning font, color, size etc.).
