-This tool is a rewrite of Mark Lowe's enum4linux.pl, a tool for enumerating information from Windows and Samba systems. It is mainly a wrapper around the Samba tools nmblookup, net, rpcclient and smbclient. Other than the original
-tool it allows to export enumeration results as YAML or JSON file, so that it can be further processed with other tools. The tool tries to do a 'smart' enumeration. It first checks whether SMB or LDAP is accessible on the target.
-Depending on the result of this check, it will dynamically skip checks (e.g. LDAP checks if LDAP is not running). If SMB is accessible, it will always check whether a session can be set up or not. If no session can be set up, the
-tool will stop enumeration. The enumeration process can be interupted with CTRL+C. If the options -oJ or -oY are provided, the tool will write out the current enumeration state to the JSON or YAML file, once it receives SIGINT
-triggered by CTRL+C. The tool was made for security professionals and CTF players. Illegal use is prohibited.
