Using XDMCP on Solarix express 9/06?

[Andrew McLaren]

Hi all,

I installed Solaris 10 6/06 x86 on one PC. From an ajacent Windows PC on
the same subnet, I ran Starnet X-Win32 8.0 to get an XDMCP login session to
the Solaris box. Everything worked okay, and life was good.

Then I installed Solaris Express 9/06 onto the Solaris box (wiped the old
6/06 installation, and started afresh). Now when I try to get an XDMCP
login, there is no response from the Solaris box.

When I start the session from XWin, I can see an XDMCP Query packet leave
the Windows box; but no XDMCP response ever comes back from the Solaris
box.

IPFilter is runing on the Solaris box, but no restricions are configured in
ipf.conf. So I don't think it's a firewall problem. It seems like nothing
is listening or responding to XDMCP queries, on the Solaris side.

I am using Xorg and the plain, default Gnome display manager.

What should I start looking at, to diagnose the problem further?

Many thanks for any suggestions,
Andrew McLaren

(BTW I recently started using Solaris again after a ~13 year break, so
please excuse any truly bozo newbie statements :-)

Might be a consequence of the new secure by default policy.

I suppose you already checked, but since you don't mention it: what does
your gdm.conf say about xdmcp?

See http://blogs.sun.com/gbrunett/entry/solaris_secure_by_default_part
and http://blogs.sun.com/gbrunett/entry/solaris_secure_by_default_part2

You can either reset the system back to the "old" behavior (for all
services) with 'netservices' or you can switch individual services to
allow use (in your case, I think you want the cde-login service)

I don't know that I exactly understand what value you want to set it to,
though. Perhaps -udpPort 1? Or maybe the bold is wrong on the table
and it's null by default and you just need to set it to -udpPort 0.

You need to remove the -udpPort flag or set it to -udpPort 177.
(The default XDMCP port is 177 - setting it to 0 disables listening on
any UDP port.)
