You are having problems to contact the X server, and the reasons can various.

What UNIX are you using?

You may need to enable remote connections (XDMCP).

More info is needed.

Example, if you are working on a Linux system and connecting to HPUX, you would not see a login window. If the HPUX isa running X then you will login to a dtterm/xterm window.

If you are using an emulator, such as Exceed or Reflections, then you can see a login screen. But this depends on how you are configured in that emulator.

It sounds like a network issue.Pls try to use "direct connect" option.Could you provide more Xmanger config?

a) Can able to reach to remote machine with
ping / telnet?

If so,

Start XManger in a passive mode. Telnet to that machine and check run level as,

# who -r

Is it 5.

From which platform you are doing remote login? Is it windows / linux?

hth.

By default, firewalls block port 7000 which is used to handle font services.

DISPLAY variable needs to be set correctly:

example: export DISPLAY=192.168.0.10:0.0

Network configuration and vlan can cause problems here.

tail -f /var/log/messages

On the target machine, try a connect. If you see nothing, its probably networking. If you see errors, share with us.
