Active OS fingerprinting tool. XProbe is a tool for determining the operating system of a remote host. They do this using some of the same techniques as Nmap as well as some of their own ideas. Xprobe has always emphasized the ICMP protocol in its fingerprinting approach.

The purpose of the tool is to perform fingerprinting of remote TCP/IP stacks based on Ofir Arkin's ICMP fingerprinting research. This tool is a practical implementation of results discovered during 'project X'.
