OS detection of that website or what OS that site runs?

[praka123]

hmm...i am no expert in networking or hacking!.want to know more about nmap tool(both for *nix and windows).many of u may be knowing this!
I have tried few sites for what that site(server os) is running.below option is what i tried ;yet to see what more options!
anyways,
as root(su) orsudo in debian,ubuntu

nmap -O -v sitename or ipaddress

so,i tried microsoft.com and it says they are running windows!too much to believe!
BTW,nmapfe is a gui.
hostsite:
http://nmap.org

Or serverspy extension to firefox is also likely to work.

Oh. That is just for the function you wrote about. Otherwise nmap is way more powerful and a very useful tool for network admins.

There are ways to spoof the OS detection method as well

^^Yeah!! There are methods to spoof OS detections and Microsoft follows that too

There's much more to nmap then just the basic stuff like OS detection. Read the man pages. Then we had queso, AFAIR!! Apart from it, nmap doesn't always reveal the OS korrectly. Then it makes sense to approximate the guesses.

# nmap IP_ADDR -O --osscan-guess

Very true! Its a security scanner; so the most common use is obvious!

[praka123]

Now the gui nmapfe is called as zenmap !(am on Debian Sid)

whatz the software used to find TTL of the IP?

[PraKs]

@max_demon

Just ping the IP, U will get TTL value

@praka123

Use this string

sudo nmap -vv -sV -O -P0 HOST NAME

make sure to off the ping - -P0

-O will tell U OS running there..

let me know if u need more details.
