[reposted under __corrected__ subject line] My linux box was set up for ipmasq with: ======= modprobe iptable_nat iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE echo 1 > /proc/sys/net/ipv4/ip_forward ======= a windows box had been browsing the net through the linux box several hours earlier (about 4 hours), and then left alone. when i went back to the windows box and tried to browse again from the same IExplorer window, _SNAP_ and the linux machine just plain up and rebooted instantly.... i am __guessing__ the problem had something to do with using an old IExplorer session so long after it had last been used??? something about NAT timeouts or something??? but a hard reboot??? apart from this crash, ipmasq had been working fine (just never tested with that kind of delay time). les schaffer other tidbits: -------------- a few hours prior to crash, i got these from net browsing on a connected windows box: Sep 24 22:14:34 localhost kernel: NAT: 0 dropping untracked packet c1afb180 1 207.88.240.105 -> 24.191.22.34 [snip] Sep 25 00:03:12 localhost kernel: NAT: 0 dropping untracked packet c33da540 1 63.211.32.65 -> 24.191.22. auth.log marks the last moment of conciousnes: Sep 25 01:37:01 localhost PAM_unix[19174]: (cron) session closed for user root no other significants things written to log. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
