well, don't run it against localhost for starters (unless you use -sT or run as non-root).
Starting nmap V. 2.03 by Fyodor (fyodor () dhp com, www.insecure.org/nmap/) pcap_open_live: socket: Socket type not supported QUITTING!
i'm going to guess that nmap is passing the loopback device to pcap_open_live and that SOCK_PACKET is (naturally) not supported on the loopback device. try scanning something other than localhost: nmap -vF -sS -P0 www.microsoft.com
Only tested on linux 2.2.0-pre and nmap 2.03 and 2.04. Something missing in the kernel perhaps? Or is it a bug in pcap/nmap?
if that doesn't work, then my guess would be that SOCK_PACKET wasn't compiled into the kernel, but there doesn't seem to be an option to do that in 2.0.36 that i can find (and i wouldn't expect one to have been added in 2.2.0, but i haven't looked at the 2.2.0 kernel yet...) -- Lamont Granquist lamontg () raven genome washington edu Dept. of Molecular Biotechnology (206)616-5735 fax: (206)685-7344 Box 352145 / University of Washington / Seattle, WA 98195 PGP pubkey: finger lamontg () raven genome washington edu | pgp -fka
