Unknown address family 0 #283

When i run such command:

nmap -p 1-65535 -T4 -A -v

In the process, after the start of "Initiating NSE at HH:MM" I always get error "Unknown address family 0" and nmap shuts down.
When scanning other ip-addresses or domain, the process ends correctly.

Nmap version 7.01 (downloaded from https://nmap.org/dist/nmap-7.01-setup.exe ). Version 6.49 behaved in same way.

I'm on Win-10 with the same 7.01 SVN version and it works here.Try adding your IP source-address and see if that make a difference:

nmap -S a.b.c.d -p 1-65535 -T4 -A -v

@billionaire I can't see what would be causing this. Can you reduce the crash to a smaller number of scan options? For example, try nmap -T4 -sC -d --script-trace to eliminate the version scan, OS detection, and traceroute, while adding some diagnostic output that could narrow in on one script in particular causing the problems.


I have the same error (?), the script stops after this warning. I do have another query running though.

nmap -T4 -O -A -v www.bluecape.nl

@timvanderweijde Thanks for bumping this issue. Found a fix, but also found another bug that affects scanning that target. See #378 for why SSL stuff won't work right on POP3, IMAP, etc. there.

Fixed in f38b959

@dmiller-nmap You're welcome. :-) And nice to see the fix already.
