Re: help regarding IP address spoofing (when using nmap)

Hi All
 I am a relatively newbie to FreeBSD (earlier was running
Linux). I am running FreeBSD 13.1.

I am trying to run nmap with source IP address spoofing
(for some academic purposes). It works fine with Linux
but on FreeBSD I get the following error:

# nmap -e re0 -S 192.168.17.92 -sS 143.110.249.18  -p 8080 -Pn
Starting Nmap 7.93 ( https://nmap.org ) at 2023-02-02 16:04 IST
NSOCK ERROR [0.0170s] mksock_bind_addr(): Bind to 192.168.17.92:0 failed
(IOD #1): Can't assign requested address (49)
NSOCK ERROR [0.0170s] mksock_bind_addr(): Bind to 192.168.17.92:0 failed
(IOD #2): Can't assign requested address (49)


It works fine without the source spoofing but doesn't when I use
it. I can however use my own machine's source IP address with
the '-S' option.
