Unfortunately ut_host is way too small for even quite short FQDNs. 
rlogind seems to do a check to see if the remote machine is in the same
domain, and if so it only uses the host part of the name.  I think this
would be good check to add first, before checking to see if the name is
too long and resorting to an IP address.  Personally I'd rather see
same-domain remote logins noted from "foo" rather than "foo.do.main",
even if foo.do.main is short enough to fit without truncation. 
Would this be a reasonable compromise?
