-P0 bug

[Jabra <jabra () spl0it org>]

There is a bug for -P0 in version 4.65. nmap -P0 seems to only
work w/ privs. If you run it w/o privs you get nothing.



$ sudo nmap -P0 localhost ...
 
Starting Nmap 4.65 ( http://nmap.org ) at 2008-06-09 22:38 EDT
Interesting ports on localhost (127.0.0.1):

...

$ nmap -P0 localhost 


Starting Nmap 4.65 ( http://nmap.org ) at 2008-06-09 22:39 EDT
Note: Host seems down. If it is really up, but blocking our ping
probes, try -PN
Nmap done: 1 IP address (0 hosts up) scanned in 0.055 seconds


$ sudo nmap -P0 x.x.x.x
