Hel with X11 and remote display...

[Pete French]

I asked this on the 'net and got zero replies for some reason. I am
tryingm to do something very simple - remote display an app. For
example 'xterm -display dogbert:0.0'

I do 'xhost +' on the X server. but it still cant connect.
Interestingly I also observer that 'xterm -display localhost:0.0'
doesnt even work!

err, help! have they done something odd to X since the last time I
tried this (a number of years ago - I normally use ssh tunneling
these days).

-bat.
