[NTLUG:Discuss] xhost question

[Fred James]

I think the simplest way to state this is as follows (where A is Linux, 
and B is IRIX):
Starting on A
(1) xhost +B
(2) telnet B
(3) setenv DISPLAY A:0
(4) xclock -title `hostname` &
(5) The error message is that the display cannot be opened.
This sequence would work if both A and B were IRIX - has been tested.
