OS from the IP

[XP_2600]

Guys, is there any method to know the OS which is running in an IP ? like getting the browser version, or the server type

i think you can visual route and it will tell you what webserver it is running

www.visualroute.com

hope it works.!

Hi, here's two things you can try;

1/ nmap http://www.insecure.org/nmap/

A tool that will attempt to guess an O.S. by the slight differences

in TCP responses

2/ telnet (run from cmd) or netcat (google it)

telnet to a port that a service is running on - eg www = port 80

hit return a couple of times and read the banner message

telnet <target> <port number>

HTTP/1.1 400 Bad Request

Server: Microsoft-IIS/4.0

Oh btw - this *may* not be legal

Most vendors have implemented parts of the TCP/IP protocol in unique ways. This enables sniffers - like nmap - to look for known characteristics, and make an educated guess as to the operating system being examined.

Fastest, and easiest way to do this is www.netcraft.com Plug the target of interest into the "what is that server running" box, click go, and wait. Very accurate.

Cheers,

www.netcraft.com works great on guessing the webserver running idd.. and nmap, recommend nmap for linux... dont know but works better and faster for me
