Bug#396062: nmap does not work on distant host

2017-09-11 Thread Lukas Schwaighofer 
Control: tags -1 + moreinfo unreproducible

Hi Fabrice,

I'm doing a bit of housekeeping of old nmap bugs.  Are you still able
to reproduce the bug you reported here more than 10 years ago:
https://bugs.debian.org/396062

I cannot reproduce the problem myself.  I suspect that this problem is
either related to something unique in your setup or has been fixed by a
newer nmap release since you reported it.

Thanks & regards
Lukas

nmap answers (0.478 seconds and 0.484 seconds) looks very fast for me
(7.242 seconds on localhost).

What does tcpdump show as the activity during the nmap 192.168.2.251?
