Christopher:
Looking at the GDM code, it only prints out the "XDMCP: Sending
UNWILLING to %s" message if the function gdm_xdmcp_host_allow()
function in daemon/gdm-xdmcp-manager.c returns FALSE.
This only happens if the following call returns FALSE:
ret = hosts_ctl("gdm", client, host, "");
In this case client would be "192.168.0.105" and host is a
value returned from the gdm_address_get_info () call, which
would be the "host" value returned from a call to getnameinfo().
Since hosts_ctl is a a libwrap() function (see "man libwrap"),
I think that the problem is likely with either your tcp wrappers
configuration, or perhaps a problem with your system configuration
not returning a good "host" value when getnameinfo() is called?
You say you see the same error regardless of how tcp wrappers is
configured, which seems odd. I'd think that you should be
able to configure tcp wrappers to always make hosts_ctl return
TRUE. If so, I'd think you'ld see a different error message
in this case. As I say above the "Sending UNWILLING" message
should not appear if hosts_ctl returns TRUE, and you should
see some other error message if it is still failing.
Just speculating, but from looking at the code, this hopefully
narrows down what you should be looking at.

Hello Brian, thanks for replying.
options/tcp_listen is set to true. That is what I meant by enabled
tcp-listen for x11. After changing that particular setting, port
6000 opened, but the connection would still breakdown with "Manager
unwilling, Host unwilling" error.
You could try setting Enable=true in the [debug] section of the
GDM configuration file (/usr/share/gdm/defaults.conf), and restart
GDM. Then try to connect and check your syslog (/var/adm/messages)
and see if there is any useful information about what might be
happening.
I did that and with tcpwrappers off, the five log messages were
esssentially the same, see below.
supernova is the machine name of the opensolaris box.
192.168.0.105 is the IP address of the computer attempting to make the
connection.
