Not able to connect to Unix server through GUI

[Eric Jacklin]

Hi

I am using Reflaction X/Xmanager to connect my Unix box but i am not able to connect through GUI session.

Any help ?

The error message is "connection timed out".
In other words, ReflectionX is sending packets to the Unix box but is getting nothing at all back - not even a "connection refused" message.

Most likely this means there's a firewall between your Windows workstation and the Unix box. Or it might be an IPFilter software package on the Unix box, or some "personal firewall" software on the Windows workstation. Whatever it is, it's dropping the packets associated with your connection.

Find the firewall and configure/have it configured to allow your connection.

If there is no firewall, this might be caused by some fairly serious configuration problems in your network, or perhaps failing network hardware.

Remember that an X GUI connection using XDMCP actually uses multiple network-level connections. See the diagram on this page:
http://en.wikipedia.org/wiki/Xdmcp

The XDMCP protocol is used for session setup only: the XDMCP connection is formed from your Windows box to the UDP port 177 of your Unix box. When the session starts up, each individual X GUI program will connect from the Unix box to TCP port (6000 + your display number, usually 0) of your Windows box.

Hi

additionally you can check out the followings

1. enable CDE
/usr/dt/bin/dtconfig -e

Ensure the initdefault level in /etc/inittab is 3

2. start CDE

/sbin/init.d/dtlogin.rc start

then try to login

Hi Jit's

What version of HP-UX are you using? I had the same problem on HP-UX 11i v3. Turned out that CDE is optional in this version. I just installed the CDE package, start it then everything is fine.

(What a user name!)

I think the solution is just above your post - check if CDE is installed.
If it isn't, install it.

You have basically the same answer in your own thread:
