xpra should handle different ssh ports

[GoogleCodeExporter]

It is currently not possible to specify an alternate ssh port when using 
xpra. The following is a diff of the latest Ubuntu version to add this 
functionality, so an ssh port can be specified like this: xpra attach 
ssh:hostname:ssh_port:x_port

Thanks for the patch!

The development version supports this already in a different way -- use 'xpra 
attach --ssh="ssh -p 2222" ssh:my.host'. (The advantage of this method is that 
it allows you to modify arbitrary ssh options, not just the port.)

• Changed state: Fixed

I know this post is old, but I am trying the latest in the repo, and I get the 
error "xpra: error: no such option: --ssh". Is there a new method to do this, 
don't see it in the man page.

--ssh argument doesn't work for changing port. The port number gets overridden by following arguments.
