an asynchronous service enumeration tool

positional arguments:
  targets               the targets and/or networks on which to perform enumeration

optional arguments:
  -h, --help            show this help message and exit
  --brute-pass-list F   filename of password list to use for brute-forcing
  --brute-user-list F   filename of user list to use for brute-forcing
  --cmd-print-width I   the maximum integer number of characters allowed when printing
                        the command used to spawn a running subprocess (defaults to 80)
  --config-dir D        the base directory from which to load the configuration files;
                        required configuration files missing from this directory will
                        instead be loaded from the default files shipped with this
                        program
  --hard                force overwrite of existing directories
  --max-concurrency I   maximum integer number of subprocesses permitted to be running
                        concurrently (defaults to 20)
  --no-program-check    disable checking the presence of required system programs
  --no-file-check       disable checking the presence of files such as configured
                        wordlists
  --no-service-scans    disable running scans on discovered services
  --output-dir D        the base directory in which to write output files
  --patterns [ [ ...]]  regex patterns to highlight in output text
  --ping-sweep          enable ping sweep filtering of hosts from a network range
                        before running more intensive scans
  --quick-only          whether to only run the quick scan (and not include the
                        thorough scan over all ports)
  --qs-method S         the method for performing the initial TCP port scan; must
                        correspond to a configured port scan
  --status-interval I   integer number of seconds to pause in between printing status
                        updates; a non-positive value disables updates (defaults to 30)
  --ts-method S         the method for performing the thorough TCP port scan; must
                        correspond to a configured port scan
  --udp                 whether to run UDP scans
  --udp-method S        the method for performing the UDP port scan; must correspond
                        to a configured port scan
  --verbose-status      whether to print verbose runtime status updates, based on
                        frequency specified by `--status-interval` flag
