XON(1) MachTen Programmer’s Manual XON(1)

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
variables to the remote command.

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 access.

Xon will attempt to open a secure shell connection to the
remote host when the SECURESHELL environment variable is
set to the secure shell path, usually ’/usr/bin/ssh’.

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 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).

-nols Normally xon passes the -ls option to the remote
xterm; this option suspends that behaviour.

-screen screen-no
This changes the screen number of the DISPLAY vari-
able passed to the remote command.

-user user-name
By default, xon simply uses rsh/remsh/rcmd to con-
nect 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 file.

Xon can get easily confused when the remote-host, user-
name or various environment variable values contain white

Xon has no way to send the appropriate X authorization
information to the remote host.
