Displaying remote X clients using XFree86

[Hero_Shema]

I really can't figure this one out folks: I'm trying to connect to a Unix Solaris machine to use a software called Opnet (GUI application). I've done it from a linux machine on hte same domain as the Solaris machine and it worked fine [opened a telnet window from my linux to the Solaris machine, logged in, typed "xhost +" on the local linux terminal to allow other machines (the Solaris machine) to take over the screen, then typed, setenv DISPLAY xxx.xxx.xxx.xxx:0.0 where xxx.xxx.xxx is the IP address of my linux machine to tell the Solaris machine to display every thing on my linux machine's screen, then tried to run the program "Opnet"]. I get the following error message:

<<< Program Abort >>>

Time: current time
product: modeler
.
.
Error: Unable to initialize windowing system:
unable to open X display

apparently, I have an xhost problem. The error says that opnet
can't open the X display (on my linux machine.)

What could be the reason for that?

to bwkaz:

Yes I'm behind a firewall and a router. However, I've disabled the firewall in linux. As for the firewall that is built into the router, I don't think I need to have any specific ports open, do I? Just in case I had the telnet port open, but that didn't matter still. How would the topology or IP address of my computer help or make any difference?


to hlrguy:

how do I spawn the xterm? I know someone who displayed the remote x server application from another linux machine (running linux 7.0) without having to do anything!!! Any way, thanks in advance.
