[BLUG] X connection between Solaris and Linux

[Jeff Welty]

OK, I opened the X11 port (6000) on the Deb side - still no joy. I
figured it was an xauth problem, but I couldn't even find anything
resembling xauth on the server side to try to merge the authorization
record from the Deb side into an .Xauthority file on the server.
I will start trying the ssh tunneling strategy, even though the
documentation for installing the Cisco transport manager (which requires
Oracle) has nothing about it... Boooo obfuscated Cisco documentation!
Man, working with Solaris is about as fun as playing with a rusty bear trap.
