Note the "ping" in this contecx may involve more than the traditional ICMP echo request packet. Nmap supports many such probes, including arbitrary combinations of TCP, UDP, and ICMP probes.

Nmap tries to determine the service protocol (e.g. ftp, ssh, telnet, http), the application name (e.g. ISC Bind, Apache httpd, Solaris telnetd), the version number, and sometimes miscellaneous details like whether an X server is open to connections or the SSH protocol version)</description>
