I have the entry

*                                       #any host can get a login window

In both the local machine, and the corresponding file on the remote
machine (/usr/X11R6/lib/X11/xdm/Xaccess).

Yet I get the response,

Fatal server error:
XDMCP fatal error: Session failed Session 444176001 failed for display hawkins.cba.uni.edu:1: Cannot open display

xdm is running on both machines.

I use ssh to get to the remote machine, set the display variable to the 
local machine, cut and paste my xauth code, and get

nsSocketINETConnect: Can't connect: errno = 61
_X11TransSocketINETConnect: Can't connect: errno = 61
_X11TransSocketINETConnect: Can't connect: errno = 61
_X11TransSocketINETConnect: Can't connect: errno = 61
_X11TransSocketINETConnect: Can't connect: errno = 61
_X11TransSocketINETConnect: Can't connect: errno = 61
xterm Xt error: Can't open display: hawkins.cba.uni.edu:0.0

Then, going for broke, I try using xhost from the local machine
to enable the remote display:

hawkinsttyp8:hawk>xhost + dhcp252-100.vlc2-100e92.cfu.net
dhcp252-100.vlc2-100e92.cfu.net being added to access control list

and in the window to the other machine, and get the same result.

As I understand these files, the * in Xaccess in the *remote* machine
should be enough to get a login screen on console vt8, and *either*
the xuath codes or the xhost+ should give me the remote screen the
ability to use the local server (and should not be affected by any
xdm settings).
