I am staying at family for the holiday week, and the easiest way
for me to get internet with my laptop is to have mom's imac share
ethernet over firewire. So far it has been working very well (so
long as we have the imac set to not sleep!) but I did find that
nmap crashes when I try to run it when my primary interface is IPoFW.
PBG4:~ nfisher$ sudo nmap -sS vftp.net
Starting nmap 3.75 ( http://www.insecure.org/nmap/ ) at

FATAL: readip_pcap: bogus caplen from libpcap (1127219200) on
interface type 138
Works fine over ethernet and wireless though.
Also fails for scan types T, F, X, N, P, V, U, O, A, W, R, L. -P0
also crashes. Scans of unspecified type and I both appear to work.
Also, this crashes
PBG4:~ nfisher$ sudo nmap vftp.net
but this does not
PBG4:~ nfisher$ nmap vftp.net
So guessing it has something to do with custom packet building on
IPoFW that's blowing things up?
