(v1.45 Beta/6) Personal Organization: BUZ Internet Services X-Priority: 3 (Normal) Message-ID: <143468894.20000807224921@buz.ch> To: stable@freebsd.org Subject: Killed natd -> system crash Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-stable@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Hello, I killed natd on one of my boxes and it ended up with a system which didn't respond to any IP connection attempts I did. Neither sshd nor any other daemon was responding, same goes for ICMP connection attempts. System Configuration ipfw was configured using the open profile and natd itself was running with the following options (started from rc.conf) natd -redirect_address 10.2.2.3 10.2.2.3 -i rl0 the box (running 4.1 Stable as of Friday, IIRC) has got three three IPs: 10.2.2.3 255.255.255.248 (rl0_alias1) 10.2.5.6 255.255.255.128 (rl0) 10.2.5.7 255.255.255.128 (rl0_alias0) At that time, the following daemons where running: - Apache 1.3.12 ModSSL 2.6.5 with approx 200 virtual host (I was doing some testing) - ProFTPd 1.2pre10 - named - qmail incl. popserver under the newest ported tcpserver supervised by the daemontools - sshd (I had two ssh connections to the box, none of them was of any use after the kill) The machine happily compiles world three or four times looped so it's surely not a hardware problem. At the moment of the crash it was approx 3,5 hours up (had rebooted it before to test if my rc.conf changes for natd would work). Prior to the 'crash', natd was working like a charm. I tend to believe that the 'crash' is related to the -redirect_address option as my normal gateway has never cared for a killed natd. Sure it stopped acting as gateway but his was the only thing. No crashes no other troubles, if I restarted natd on it, it did it's service as it should.
