Hi all, I got a strange problem with my FreeBSD 2.2.5 machine, which is used as mail/pop3, ftp and httpd servers. Two network interface cards are installed on it, one is used to connect Internet, another is to connect an internal network. All machines (PC and MACs) internal network use NATD to do external access. This morning, we found at first that a pop3 client took more than 5 minutes to download emails from this pop3 server (sometimes failed), and later found that ftp and httpd services did too. It was very quick last Thursday, this machine was not turned down during the following holidays. But it looks no slow to access those servers from external Internet or access Internet from internal machines. So, what is the problem? I checked all the logs outputed from system processes, only one message repeated several times in /var/log/message may be useful. <First appeared> Apr 2 11:08:19 wizeup natd: failed to write packet back (Permission denied) Apr 2 11:08:49 wizeup natd: failed to write packet back (Permission denied) Apr 2 11:10:54 wizeup last message repeated 4 times Apr 2 11:13:10 wizeup last message repeated 4 times Apr 2 11:13:21 wizeup popper[11123]: (v2.4b2) Unable to get canonical name of c lient, err = 0 ... <last appeared> Apr 2 12:04:14 wizeup natd: failed to write packet back (Permission denied) Apr 2 12:05:01 wizeup last message repeated 2 times Apr 2 12:06:26 wizeup last message repeated 3 times Apr 2 12:10:52 wizeup last message repeated 9 times Apr 2 12:13:44 wizeup popper[12629]: (v2.4b2) Unable to get canonical name of c lient, err = 0 Does any body help it?
