Sun changed the semantics of the gethostbyaddr() resolver function and changed several programs, including rlogin, to depend on the changed semantics for security. The change has gethostbyaddr() checking its result with a call to gethostbyname(), i.e. checking that the DNS has both a PTR record and a matching A record for that IP address and associated host name. The intent is to prevent spoofing. IMHO, this ought to be done either in the application program or in a separate library call. Regards, Chuck
