If you have entries in your /etc/hosts.allow or /etc/hosts.deny that explicitly specify hosts, or an entry turning on PARANOID when you telnet into the box it does a reverse (then forward if PARANOID) DNS lookup to make sure you're allowed to have access.. Also, login does a reverse lookup to put a hostname in /var/log/utmp. Check your /etc/resolve.conf. Or it could be identd, but I've never had a problem with that before. ------_=_NextPart_001_01C05A30.BC22751E Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2//EN">RE: Quick question >
