My mail server (4.2-STABLE) was hacked with the telnetd bug--I had forgotten it was still on, and thought everything was being done with SSH. Bad me. Anyway, it was a convienent excuse to upgrade to a newer version of FreeBSD (and Sendmail, too boot). Everything's up and running smoothly, except... Certain hosts are timing out SMTP connections. Mail gets sent via Sendmail, gets deferred, and deleted from the queue eventually. If I telnet to port 25 on those hosts, it will connect eventually (on the order of several minutes later). If I try the same telnet on the other hosts in my subnet (Tru64 and Linux), the connection is almost instaneous. This seems to indicate it's a FreeBSD issue, not necessarily a sendmail one. Any thoughts on why my new FreeBSD box is being so slow for SMTP traffic? -- Dan Bongert dbongert@ssc.wisc.edu SSCC Unix System Administrator To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
