fsockopen to own server

Hello. I'm having a problem with fsockopen and was wondering has anyone ever noticed a case where it will work from machine1 (dev machine) to machine2. But when the was placed onto machine2 it wouldn't work connecting to it's own ip address; when connecting via telnet it returns: Escape character is '^]'. * OK [CAPABILITY IMAP4REV1 LOGIN-REFERRALS AUTH=LOGIN] serverip IMAP4rev1 2003.339-cpanel at Wed, 15 Dec 2004 19:33:27 +0000 (GMT) so I don't think it's the firewall. the error it returns is "No such file or directory". So it seems that when it connects (which it does without failing), the file seems to be deleted, as the file the variable refers to doesn't exist on the fs either. if(($s = fsockopen($id["sockname"], 0, $errno, $errstr)) === FALSE) $id["sockname"] is in the format /tmp/filename with the filename changing based on a random value and there are no files with that format in /tmp it always returns false for some reason on this server. Thanks in advance for your help. Dave
