It seems to be it would be most valuable, especially as more and I had a spare hour this afternoon, and I just got it working again on an SMP PIII running a -stable that's only a few weeks old. I think it was failing due to changes in the ip_fw_chk_ptr() interface. Sorry I didn't have time to debug it when you tried it earlier. I've left a tarball at: http://people.freebsd.org/~gallatin/netdump.tgz Its still something of a hack -- you must be running an fxp or a de interface for it to work. You also need to have ipfw compiled into the kernel... I'm using: options IPFIREWALL #firewall options IPFIREWALL_FORWARD #enable transparent proxy support options IPFIREWALL_DEFAULT_TO_ACCEPT #allow everything by default For some reason, automatic sysctl installation no longer works, so if you want to disable partial dumps, you'll need to manually do it at compile time (or via ddb or gdb).
