xon - start an X program on a remote machine
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
When no command is specified, xon runs 'xterm -ls'. It additionally
specifies the application 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
Note that the options follow the remote host name (as they
do with rlogin).
Xon can get easily confused when the remote-host, user-name or various
environment variable values contain white space.
- 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.
- Normally, xon disconnects the
remote process from stdin, stdout and stderr to eliminate the daemon processes
which usually connect them across the network. Specifying the -debug option
leaves them connected so that error messages from the remote execution
are sent back to the originating host.
- -name window-name
- This specifies a different
application name and window title for the default command (xterm).
xon passes the -ls option to the remote xterm; this option suspends that
- -screen screen-no
- This changes the screen number of the DISPLAY
variable passed to the remote command.
- -user user-name
- 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 has no way to send
the appropriate X authorization information to the remote host.
