[ale] X + SSH question

[John C]

thanks....   Never though it was that simple.  Works great.

I've been going around the world to do the same thing.

Augh!  Crucioal typo in my instructions.  The -x flag should be -X.

I've corrected it below.

You are in luck.  SSH does this for you automatically.  If you turn on
X forwarding, either in your config file or with -X.  At each stage it
will tunnel X through SSH to the previous DISPLAY.  I think you can do
arbitrarily long chains of SSH logins like this.

Just "ssh -X intermediatehost" then "ssh -X remotehost"
