So I *think* that means you ran xhost on your local machine, which is
correct. Also check any firewalling, it isn't unusual to block X11
ports. What you can also do as a test is to see if something is
listening that you can get to:
telnet to remote;
from there, telnet to your local machine on the X11 port 6000:
telnet <wherever> 6000

Have a second telnet open on the remote, and just kill the telnet pid if
it allows a connect. If it says "connection refused", it means it is
either firewalled or nothing is listening. Try it from localhost just to
see what it does when a listening server is telnet'd to.
