xon - start an X program on a remote machine
xon remote-host [-access] [-debug] [-name window-name] [-nols] [-screen screen-no] [-user
user-name] [command ...]
Xon runs the specified command (default xterm -ls) on the remote machine using rsh, remsh,
or rcmd. Xon passes the DISPLAY, XAUTHORITY and XUSERFILESEARCHPATH environment variables
to the remote command.
When no command is specified, xon runs 'xterm -ls'. It additionally specifies the appli-
cation name to be 'xterm-remote-host' and the window title to be '-fIremote-host'.
Xon can only work when the remote host will allow you to log in without a password, by
having an entry in the .rhosts file permitting access.
Note that the options follow the remote host name (as they do with rlogin).
Runs xhost locally to add the remote host to the host access list in the X server.
This won't work unless xhost is given permission to modify the access list.
-debug Normally, xon disconnects the remote process from stdin, stdout and stderr to elim-
inate the daemon processes which usually connect them across the network. Specify-
ing the -debug option leaves them connected so that error messages from the remote
execution are sent back to the originating host.
This specifies a different application name and window title for the default com-
-nols Normally xon passes the -ls option to the remote xterm; this option suspends that
This changes the screen number of the DISPLAY variable passed to the remote com-
By default, xon simply uses rsh/remsh/rcmd to connect to the remote machine using
the same user name as on the local machine. This option cause xon to specify an
alternative user name. This will not work unless you have authorization to access
the remote account, by placing an appropriate entry in the remote users .rhosts
Xon can get easily confused when the remote-host, user-name or various environment vari-
able values contain white space.
Xon has no way to send the appropriate X authorization information to the remote host.
