[rescue] SunOS 4.1.3 X-Windows client to modern Linux System, How?

[Dave McGuire]

  X11 ssh forwarding does work, but it's not fast on old iron.  Not fast
at all.  Honestly, it's best to go through the machinations to have the
modern machine accept connections on port 6000 (+screen), as God (and
Jim Gettys et al) intended.

  Another trick is to use socat:

socat tcp-l:6000,fork,reuseaddr unix-connect:/tmp/.X11-unix/X0

  This will cause the machine on which it's executed to accept external
TCP connections on port 6000 and forward them to the specified UNIX socket.

  I use that trick as a stopgap when I'm working on a machine that would
be painful to log out of to restart the X server. (hundreds of windows
open and lots of context that I don't want to lose)
