Connecting to Other X Window Systems
You can connect from Mac OS X to other X window systems using ssh with X11 forwarding. If you use OpenSSH (which is included with Mac OS X; see Section 7.5), you must use the -X option to request X11 forwarding (the -2 option specifies the ssh Version 2 protocol, as opposed to the older Version 1 protocol). For example:
ssh -2 -X remotemachine -l username
As long as XDarwin is running, this can be entered in either an
xterm window or in the Mac OS X Terminal. To
have the X11 forwarding enabled in Terminal, you must have the
DISPLAY
variable set as noted earlier prior to
making the connection. (This is always the case if the
DISPLAY
variable is set in your
.tcshrc script.) It is also possible to make a
double-clickable application that connects to a remote machine via
ssh2 with X11 forwarding enabled. For example,
the following script can be used for this purpose:
#!/bin/sh ssh -2 -X remotemachine -l username
If you’ve installed the commercial version of ssh from http://www.ssh.com, the equivalent of the preceding script is given with the following:
#!/bin/sh ssh2 remotemachine -l username
Using OroborOSX, you can add a Launch menu item to accomplish the
same task. To do this, start by copying the template file found in
the directory ~/Library/Preferences/OroborOSX/Launch Menu
Items
to whatever you’d like to call this
application. For this example, suppose you want to connect to a
remote machine named chops with a username of
sam. Name the application ...
