Hi People, I how you can help me out with this issue.. Im not sure if it is a raptor problem or if the problem is located somewhere else, but im gonna start here.
Im trying to make Reflection X work on my workstation at work.. We have a
semi-advanced setup,
which can result in serval errors but I think i've configured most things
good enough..
A little description about our setup..
Im connecting from my workstation ((my workstation)) to the Linux Box in a
DMZ zone ((linux box) - public IP)
through a firewall (a Raptor Firewall) with ip xxx.xxx.xxx.xx ..
So all connections comming from my workstation are patted by the Raptor
Firewall.
When im connecting to the Linux machine im connecting through a Raptor
Firewall.. (
We've added a Reverse zone, so the linux is reversing perfectly to my
workstation)..
We've opend for the following ports in the firewall, which allow us to
connect to the linux server on the DMZ:
xdmcp 177/tcp X Display Manager Control Protocol
xdmcp 177/udp X Display Manager Control Protocol
x11 6000-6063/tcp X Window System
x11 6000-6063/udp X Window System
font-service 7100/tcp X Font Service
font-service 7100/udp X Font Service
As you can figure out I am connecting with XDMCP .. It is working if I am
connecting via OpenSSH and then manually
starts X and KDE.
About the log on the Linux machine I get the following errors, when I try
to connect via XDMCP:
in var/log/messages:
Nov 1 12:34:15 hymer su(pam_unix)[1987]: session opened for user nobody
by (uid=0)
Nov 1 12:34:15 hymer su(pam_unix)[1987]: session closed for user nobody
in var/log/xdm-errors

xdm error (pid 789): Display (my workstation):0 cannot be opened
xdm error (pid 789): Display (my workstation):0 is being disabled
if I do a tcpdump on the linux machine i get the following:

I've reach the point where im looking at this blindly.. I can't come up
with any possible solutions, so thats why
