Remember that not all IP adrresses will resolve to a hostname. That said, there may be a flaw in your logic in the code snippet above :-) What you are saying is: gethostname for IPADDR; if HOSTNAME = IPADDR print HOSTNAME which will only work if the resolved hostname is the same as the IP address; I suspect that is not what you want? -- David Robley Techno-JoaT, Web Maintainer, Mail List Admin, etc CENTRE FOR INJURY STUDIES Flinders University, SOUTH AUSTRALIA Bald: follicularly challenged. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
