Xnest is meant for running multiple X sessions in the same server. If you want to access a remote machine's gdm, then you don't need Xnest for that. You can test for UDP port 177 along with the TCP ports 6000 and above with the nmap command. # nmap -sT -p 6000-6005 bsd.example.org # For X # nmap -sU -p 177 bsd.example.org # For XDMCP Most likely you have to enable TCP listening in gdm.conf. Just uncomment the relevant line and you should be all set. Best of luck! -Girish P.S. /* off-topic I'm new to the *BSD world and it's my first message to this list.

I am confused why you need Xnest.
If you want the XDMCP of the remote host there are other means. Xnest
is meant for running multiple X sessions in the same server.
If you want to access a remote machine's gdm, then you don't need
Xnest for that.
Indeed. It is not my intention to use XDMCP like that (although it has
some advantages in some cases), but since the remote host wasn't on the
local XDMCP list I tried a more direct approach.
You can test for UDP port 177 along with the TCP ports 6000 and above
with the nmap command.
# nmap -sT -p 6000-6005 bsd.example.org # For X
# nmap -sU -p 177 bsd.example.org # For XDMCP
Sorry, I forgot to mention that. nmap gives:
PORTSTATE SERVICE
177/udp closed xdmcp
6000/tcp open X11
Actually I think the latter is not required, but I'll let everything be
open and allowing until I get it working, then I'll disable the
unnecessary options afterwards.
Most likely you have to enable TCP listening in gdm.conf. Just
uncomment the relevant line and you should be all set.
Now, this is where I get confused. In the gdm(1) man page it is stated
the configuration file should be gdm.conf. Well, the man page is from
2003 and pkg_info -L doesn't show such a file. Instead there is
custom.conf{,.default} and gdmsetup seems to be writing to this one.
Its content seems OK (meaning policy=allow all) to me:
sed -e '/^$/d;/#/d' /usr/local/etc/gdm/custom.conf
[daemon]
[security]
AllowRemoteRoot=true
DisallowTCP=false
[xdmcp]
Enable=true
[gui]
[greeter]
Use24Clock=yes
[chooser]
[debug]
[servers]
So, I believe there's something about gdm that I'm still missing or
it's just not working on FreeBSD. (bug?)
Best of luck!
-Girish
Thanks and the same to you!
(Although I'd appreciate more help than luck in this case.)

Then your problem is right here.
The XDMCP port is closed.

Don't think so.

Open the XDMCP port and you are done.
