When you connect with telnet, for example, telnetd does a reverse lookup for the name from the IP address - so it doesn't matter what you specify on the client machine, the DNS problem is on the server; it's having trouble either getting to the nameserver, or the nameserver is having trouble getting to the authority for your in-addr.arpa zone. -DG David Greenman Core-team/Principal Architect, The FreeBSD Project To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
