It looks like its happening as the ethernet connection comes up. What happens if you ifdown eth0 and then ifup eth0 ? Check in /etc/network/if-up.c and /etc/network/if-pre-up.d for anything that may try to run. On my system, shorewall starts immediatly after networking in /etc/rcS.d. I don't know why you appear to be getting errors from a firewall unless your firewall script runs before networking comes up. Since this is all happening in /etc/rcS.d, I'd suggest booting with init=/bin/sh and running the /etc/rcS.d scripts manually one at a time to try to track it down. If you can get a shell while these errors are happening, perhaps you can see what processes are running. Doug. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
