Network exploration tool and security / port scanner |
-sV (Version detection) . Enables version detection, as discussed above. Alternatively, you can use -A, which enables version detection among other things. |
-sC . Performs a script scan using the default set of scripts. It is equivalent to --script=default. Some of the scripts in this category are considered intrusive and should not be run against a target network without permission. |
-O (Enable OS detection) . Enables OS detection, as discussed above. Alternatively, you can use -A to enable OS detection along with other things. |
-oA basename (Output to all formats) . As a convenience, you may specify -oA basename to store scan results in normal, XML, and grepable formats at once. They are stored in basename.nmap, basename.xml, and basename.gnmap, respectively. As with most programs, you can prefix the filenames with a directory path, such as ~/nmaplogs/foocorp/ on Unix or c:\hacking\sco on Windows. |
