XDMCP

Hi all

I've got 3 Unix workstations (running hpux 10.20) which I need to access via X-Windows (Reflection X V.11). 2 of them are running fine. One makes a lo of trouble. When I try to connect I get a XDMCP timeoout. Is there any possibility to troubleshoot this connection?

There may be multiple causes :
. Is network connnection good enough to that server ?
. Is port 6000 allowed between this server and your PC ? (FW ?)
. Is your reflection X configured to accept connections from this host ?

I would have like to know wether you use an XDMCP connection to host, or do you only launch reflexion X and export DISPLAY on your telnet connection to this host ?

Regards,

Fred

- We use VUE as graphical output

- The connection is setup as XDMCP direct connection to the servers

Hi

Play with these resource values in /usr/vue/config/Xconfig:

Vuelogin*openTimeout: #Default 30 seconds
Vuelogin*grabTimeout: #Default 3 seconds

Try

Vuelogin*openTimeout: 40
Vuelogin*grabTimeout: 4

Restart vue

Then try again

Also

run dr_vue
look in /var/vue/Xerrors

Telnet to a WORKSTATION and do

who -R

check name resolving by nslookup of pc ON WORKSTATION AND WORKSTATION ON PC
