open Xwin Server on windows XP machine
open putty session and set Enable X11 forwarding
using putty open connection to Solaris 10 db server logged in as "oracleuser"
BASH_VERSINFO=(="3" ="00" ="16" ="1" ="release" ="sparc-sun-solaris2.10")
DISPLAY is NOT set
Error: Can't open display: localhost:10.0
/usr/openwin/bin/xhost: unable to open display "localhost:10.0"
any and all attempts to run anything X11 related end up with the same message
1. can you check if your Windows XServer display can be reached from Solaris10 machine directly (without ssh/X11 forwarding), like
Solaris$ xterm -display a.b.c.d:0 &
where a.b.c.d is the IP address of the Windows machine where XServer runs?
2. Can you try some other XServer on Winwows PC, like Cygwin/X?
Also, once Cygwin ssh/X forwarding proves to work, you can start your original XServer, but use Cygwin ssh to further trouble-shoot X forwarding. Basically, having two different X11 servers and two different ssh clients should give you some more trouble-shooting options.
On the good box I used
/usr/openwin/bin/xterm -display localhost:10
Success Xterminal popped up on Windows machine
from problem box I got
/xterm Xt error: Can't open display: localhost:10
But! I noticed something this time.
so I shutdown all putty sessions
deleted my saved entry for the Problem Solaris box
And low and behold - Success
The entry in putty must have been corrupt. When I was connecting to the Solaris box the connection was failing to register in .Xauthority (this is what i noticed!) so, i guess, the key in there was out of date and so... issues.
Thanks for the advice. It opened up a new avenue of investigation which is what I needed.
