problem while connecting [1]

Hello everybody,
I have a problem while connecting to the server.
I have this message:


Remote command has been requested.
/usr/bin/X11/xterm: Command not found.

It is the command written in the help pages.
I dont know what I should write in the command space.

Could you help me please.

Thanks in advance

The command depends on the vendor and version of your Unix machine.

Try clicking the arrow button on the end of the command box to select an appropriate command.

If it doesn't work, let me know the version of your Unix box.
