NAME

       zmap - The Fast Internet Scanner

SYNOPSIS

       zmap [ -p <port> ] [ -o <outfile> ] [ OPTIONS... ] [ ip/hostname/range ]

DESCRIPTION

       ZMap  is  a  network  tool  for  scanning  the entire Internet (or large samples). ZMap is
       capable of scanning the entire  Internet  in  around  45  minutes  on  a  gigabit  network
       connection, reaching ~98% theoretical line speed.

OPTIONS

   BASIC OPTIONS
       ip/hostname/range
              IP  addresses  or  DNS hostnames to scan. Accepts IP ranges in CIDR block notation.
              Defaults to 0.0.0/8

       -p, --target-port=port
              TCP or UDP port number to scan (for SYN scans and basic UDP scans)

       -o, --output-file=name
              When using an output module that uses a file, write results to this file. Use - for
              stdout.

       -b, --blacklist-file=path
              File  of  subnets to exclude, in CIDR notation, one-per line. It is recommended you
              use this to exclude RFC 1918 addresses, multicast, IANA reserved space,  and  other
              IANA  special-purpose  addresses. An example blacklist file blacklist.conf for this
              purpose.

   SCAN OPTIONS
       -n, --max-targets=n
              Cap the number of targets to probe. This can either be a number (e.g. -n 1000) or a
              percentage  (e.g.  -n  0.1%)  of  the  scannable  address  space  (after  excluding
              blacklist)

       -N, --max-results=n
              Exit after receiving this many results

       -t, --max-runtime=secs
              Cap the length of time for sending packets

       -r, --rate=pps
              Set the send rate in packets/sec

       -B, --bandwidth=bps
              Set the send rate in bits/second (supports suffixes G, M, and K (e.g. -B 10M for 10
              mbps). Thi s overrides the --rate flag.

       -c, --cooldown-time=secs
              How long to continue receiving after sending has completed (default=8)

       -e, --seed=n
              Seed  used to select address permutation. Use this if you want to scan addresses in
              the same order for multiple ZMap runs.

       --shards=N
              Split the scan up into  N  shards/partitions  among  different  instances  of  zmap
              (default=1). When sharding, --seed is required.

       --shard=n
              Set  which  shard  to  scan  (default=0). Shards are 0-indexed in the range [0, N),
              where N is the total number of shards. When sharding --seed is required.

       -T, --sender-threads=n
              Threads used to send packets. ZMap will attempt to detect  the  optimal  number  of
              send threads based on the number of processor cores.

       -P, --probes=n
              Number of probes to send to each IP (default=1)

       -d, --dryrun
              Print out each packet to stdout instead of sending it (useful for debugging)

   NETWORK OPTIONS
       -s, --source-port=port|range
              Source port(s) to send packets from

       -S, --source-ip=ip|range
              Source  address(es)  to  send  packets  from.  Either  single  IP  or  range  (e.g.
              10.0.0.1-10.0.0.9)

       -G, --gateway-mac=addr
              Gateway MAC address to send packets to (in case auto-detection does not work)

       -i, --interface=name
              Network interface to use

   PROBE OPTIONS
       ZMap allows users to specify  and  write  their  own  probe  modules.  Probe  modules  are
       responsible for generating probe packets to send, and processing responses from hosts.

       --list-probe-modules
              List available probe modules (e.g. tcp_synscan)

       -M, --probe-module=name
              Select probe module (default=tcp_synscan)

       --probe-args=args
              Arguments to pass to probe module

       --list-output-fields
              List the fields the selected probe module can send to the output module

   OUTPUT OPTIONS
       ZMap  allows users to specify and write their own output modules for use with ZMap. Output
       modules are responsible for processing the fieldsets returned by  the  probe  module,  and
       outputing  them  to  the user. Users can specify output fields, and write filters over the
       output fields.

       --list-output-modules
              List available output modules (e.g. tcp_synscan)

       -O, --output-module=name
              Select output module (default=csv)

       --output-args=args
              Arguments to pass to output module

       -f, --output-fields=fields
              Comma-separated list of fields to output

       --output-filter
              Specify an output filter over the fields defined  by  the  probe  module.  See  the
              output filter section for more details.

   ADDITIONAL OPTIONS
       -C, --config=filename
              Read a configuration file, which can specify any other options.

       -q, --quiet
              Do not print status updates once per second

       -g, --summary
              Print configuration and summary of results at the end of the scan

       -v, --verbosity=n
              Level of log detail (0-5, default=3)

       -h, --help
              Print help and exit

       -V, --version
              Print version and exit

   UDP PROBE MODULE OPTIONS
       These  arguments  are all passed using the --probe-args=args option. Only one argument may
       be passed at a time.

       file:/path/to/file
              Path to payload file to send to each host over UDP.

       template:/path/to/template
              Path to template file. For each destination host, the template file  is  populated,
              set as the UDP payload, and sent.

       text:<text>
              ASCII text to send to each destination host

       hex:<hex>
              Hex-encoded binary to send to each destination host

       template-fields
              Print information about the allowed template fields and exit.

   OUPUT FILTERS
       Results  generated  by  a  probe  module can be filtered before being passed to the output
       module. Filters are defined over the output fields of a probe module. Filters are  written
       in  a  simple  filtering  language,  similar  to  SQL,  and  are  passed to ZMap using the
       --output-filter option. Output filters are commonly used to filter out duplicate  results,
       or to only pass only sucessful responses to the output module.

       Filter  expressions  are  of the form <fieldname> <operation> <value>. The type of <value>
       must be either a string or unsigned integer literal, and match the  type  of  <fieldname>.
       The  valid  operations for integer comparisons are = !=, ,, =,=. The operations for string
       comparisons are =, !=. The --list-output-fields flag will print what fields and types  are
       available for the selected probe module, and then exit.

       Compound  filter  expressions  may  be  constructed  by combining filter expressions using
       parenthesis to specify order of operations, the &&  (logical  AND)  and  ||  (logical  OR)
       operators.

       For  example,  a  filter for only successful, non-duplicate responses would be written as:
       --output-filter="success = 1 && repeat = 0"
