Note the "ping" in this context may involve more than the traditional ICMP echo request packet. Nmap supports many such probes, including arbitrary combinations of TCP, UDP, and ICMP probes.
By default, Nmap sends an ICMP echo request and a TCP ACK packet to port 80. ]]> checkbox -sV servicever A file called nmap-service-probes is used to determine the best probes for detecting various services and the match strings to expect.
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). ]]> checkbox -O osdetect In other words, it uses a bunch of techniques to detect subtleties in the underlying operating system network stack of the computers you are scanning.
It uses this information to create a "fingerprint" which it compares with its database of known OS fingerprints (the nmap-os-fingerprints file) to decide what type of system you are scanning. ]]> checkbox nmap_custom_add_php_command(); nmap_custom_php_validation_command($_POST, $input_errors); nmap_install(); nmap_deinstall();
