Re: Nmap and nessus commands

Hi Sohail,

I hope that You have not been flooded with answers already :).

To scan a network or a host w. nmap I recommend

nmap -sS -P0 -sV -O <target>

Where target may be a single IP, a hostname or a subnet, which I understand is what You want.

So for the classical private IP range You may use
nmap -sS -P0 -sV -O 192.168.1.*

Please notice that a quite large subnet with firewalled machines needs some time w. my recommended command.

I also recommend You the website of nessus: - propably the best to get You fed up with tons of security related infos.

Good luck,
