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.

Sorry, I forgot to mention that. nmap gives:
PORT STATE 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.

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?)

Thanks and the same to you!
(Although I'd appreciate more help than luck in this case.)
