I said that? I guess I might have...
The actual tip is:
OpenSSH will not forward X connections if the local DISPLAY variable
is not set. I.e.
export DISPLAY= ; ssh -X server ; netscape <-- "Cannot open display"
export DISPLAY=:0.0 ; ssh -X server ; netscape <-- works
No idea if it's true of other SSHs.
The hostname part in DISPLAY is not needed. In fact, on my box (snapper;
woody, OpenSSH 2.9.9p2),
export DISPLAY=snapper:0.0 ; ssh -X server ; nedit
connect snapper port 6000: Connection refused
so it's actually *wrong*. IIRC it worked on some old version of OpenSSH
(or maybe it was just a brane fart), but it certainly doesn't work now.
