Thinking that I'd get around the following problem, I switched my

following attack method...

sudo nmap -sS -p '1-65535' -g 53 -oG foo.gnmap  -T 4 -iL foo.list

I get the following..

sendto in send_ip_raw: sendto(6, packet, 28, 0,, 16) =>
Can't assign requested address
Sleeping 15 seconds then retrying

foo.list contains the following

$ cat foo.list


This is on FreeBSD 4.9-RELEASE with all current patches and a
GENERIC kernel. If there's any more information you need, please let
me know. Note: doing a SYN scan against hosts doesn't cause this
problem, only using an input list.

I am using a freebsd box to do a lot of scanning. I seem to remember a problem depending on the security, where it would start blocking packets after a certain threshold and I had to make some changes to get it to work. I am not a bsd expert, and have not looked at in a while, so I can't remember what it was but I will see if I can find it.
