Hi all,

i recently been playing with ipfw and added the following rules:

voyager# ipfw list
01000 deny tcp from any to any 111,587,3306
01100 deny udp from any to any 111,587,3306
01200 allow tcp from any to any established
65000 allow ip from any to any
65535 deny ip from any to any

After that I discovered several problems with nmap, for example:

voyager# nmap -sT localhost
Strange error from connect (13):Permission denied
...scan will continue.

voyager# nmap -sS localhost
sendto in send_tcp_raw: sendto(3, packet, 40, 0, 127.0.0.1, 16) =>
Permission denied
Sleeping 15 seconds then retrying
...scan will stop.

Can these errors be avoided somehow? Any help will be appreciated,

Thanks.

fyi: running freebsd 4.2-release and nmap 2.54BETA22
