nmap scanning domain names
I was wondering if someone can advise please. I want to run scan against 10 web servers using nmap, my aim is to discover which server is hosting which web site.
For example I have webserv1 thatís host 3 websites and about 5 subdomains against each domain name.
Is there an nmap command that can discover and report all web website and their sub-domains per server?
It does not have to be nmap, and I would appreciate if you could suggest any other open source software to use.
Thank you in advance.
