 There is a library function gethostbyaddr(3).  Its function is to convert an
numeric internet address to a domain name.

 When you 'rlogin', this function is called to find your domain name, and check
against the domain names listed in /etc/hosts.equiv and in .rhosts.

 You must make sure that the entry in .rhosts is exactly what gethostbyaddr()
will return.  Depending on the version, gethostbyaddr() may get its information
from /etc/hosts, or from the DNS database.  It may or may not be case
independent in its comparison (better assume not).  There may be multiple
versions of gethostbyaddr() on your system, installed in different libraries.

 Good luck.
