Is your office and server on different LANS? Do you have a firewall in between?

we have this problem also but we use reflection, sometimes I use broadcast and it works and sometimes it doesn't.

There's no corporate or desktop firewall between our offices and where the servers are located.

First of, check the daemon if its running if not start it
ps -ef |grep dtlogin
/etc/rc2.d/S99dtlogin start # start it if no dtlogin process if running

You might try to use the direct method instead of the broadcast one as sometimes it works sometimes not like sparcguy said Smilie

check whether gdm is running or not ,if not start it using
gdm commad default has xdcmp set so it can solve ur problem

gdm I think is only for solaris 10? solaris 8 no such command.

I checked ard, it seems you need to open tcp ports 6000-6010 bidirectional and udp port 177 birectional also.

if you have a desktop PC antivirus with builtin firewall software like trendmicro, or norton or windows XP firewall or both and a corporate firewall between your office and your datacenter where your boxes are located you need to open all these ports on all the firewalls.

alas I'm still not able to get my reflection X to connect to any servers whether using direct/indirect/broadcast, somehow it's not coming. I'm thinking could be server side, still investigating. Smilie

for solaris 10 and below, there is a file /usr/dt/config/Xconfig

inside this file are configuration entries look for something which says.

# To disable listening for XDMCP requests from X-terminals.
Dtlogin.requestPort: 0

'#' it out and restart machine,

Solaris 10's.

1. Log in as root

2. Open a terminal

3. type gdmsetup (a dialog box will appear)

4 Click on the XDMCP tab

5. Check the Enable XDMCP box

6. Press Close

unfortunately for my case, my solaris8 box is already '#' out for the entry and it's still not coming Smilie Smilie ... investigating again.

omc 12130 11963 0 17:14:17 pts/2 0:00 grep dtlogin

I can not find the process.
any advice?
