There is a UNIX primer available in GSI's RZ/Benutzerberatung. You can login to a UNIX system via telnet from any workstation or X-terminal. However, since the keyboard layout and keycode interpretation is different for AIX and ULTRIX it is best to login on an ULTRIX machine using a VT-keyboard and on an AIX-machine using a HFT or MF2-keyboard. Special FOPI commands telvt and telaix are provided for crosswise login.
