Look in the tail of /var/log/messages on the Linux machine for messages
from [xkg]dm.  XDMCP is very sensitive to DNS, so make sure the reverse
DNS lookup from Linux for the IP address of machine #2 returns the correct
FQDN for machine #2.  If you don't have access to the DNS configuration,
simply add machine #2 to the /etc/hosts file on the Linux machine.
