- Nmap 7.70SVN ( https://nmap.org )
- Usage: nmap [Scan Type(s)] [Options] {target specification}
- TARGET SPECIFICATION:
- Can pass hostnames, IP addresses, networks, etc.

- -iR <num hosts>: Choose random targets
- --exclude <host1[,host2][,host3],...>: Exclude hosts/networks
- --excludefile <exclude_file>: Exclude list from file
- HOST DISCOVERY:
- -sL: List Scan - simply list targets to scan
- -sn: Ping Scan - disable port scan
- -Pn: Treat all hosts as online -- skip host discovery
- -PS/PA/PU/PY[portlist]: TCP SYN/ACK, UDP or SCTP discovery to given ports
- -PE/PP/PM: ICMP echo, timestamp, and netmask request discovery probes
- -PO[protocol list]: IP Protocol Ping
- -n/-R: Never do DNS resolution/Always resolve [default: sometimes]
- --dns-servers <serv1[,serv2],...>: Specify custom DNS servers
- --system-dns: Use OS's DNS resolver
- --traceroute: Trace hop path to each host
- SCAN TECHNIQUES:
- -sS/sT/sA/sW/sM: TCP SYN/Connect()/ACK/Window/Maimon scans
- -sU: UDP Scan
- -sN/sF/sX: TCP Null, FIN, and Xmas scans
- --scanflags <flags>: Customize TCP scan flags
- -sI <zombie host[:probeport]>: Idle scan
- -sY/sZ: SCTP INIT/COOKIE-ECHO scans
- -sO: IP protocol scan
- -b <FTP relay host>: FTP bounce scan

- -p <port ranges>: Only scan specified ports
- Ex: -p22; -p1-65535; -p U:53,111,137,T:21-25,80,139,8080,S:9
- --exclude-ports <port ranges>: Exclude the specified ports from scanning
- -F: Fast mode - Scan fewer ports than the default scan
- -r: Scan ports consecutively - don't randomize
- --top-ports <number>: Scan <number> most common ports
- --port-ratio <ratio>: Scan ports more common than <ratio>
- SERVICE/VERSION DETECTION:
- -sV: Probe open ports to determine service/version info
- --version-intensity <level>: Set from 0 (light) to 9 (try all probes)
- --version-light: Limit to most likely probes (intensity 2)
- --version-all: Try every single probe (intensity 9)
- --version-trace: Show detailed version scan activity (for debugging)
- SCRIPT SCAN:
- -sC: equivalent to --script=default
- --script=<Lua scripts>: <Lua scripts> is a comma separated list of
- directories, script-files or script-categories
- --script-args=<n1=v1,[n2=v2,...]>: provide arguments to scripts
- --script-args-file=filename: provide NSE script args in a file

- -O: Enable OS detection
- --osscan-limit: Limit OS detection to promising targets
- --osscan-guess: Guess OS more aggressively
- TIMING AND PERFORMANCE:

- 's' (seconds), 'm' (minutes), or 'h' (hours) to the value (e.g. 30m).
- -T<0-5>: Set timing template (higher is faster)
- --min-hostgroup/max-hostgroup <size>: Parallel host scan group sizes
- --min-parallelism/max-parallelism <numprobes>: Probe parallelization
- --min-rtt-timeout/max-rtt-timeout/initial-rtt-timeout <time>: Specifies
- probe round trip time.
- --max-retries <tries>: Caps number of port scan probe retransmissions.
- --host-timeout <time>: Give up on target after this long
- --scan-delay/--max-scan-delay <time>: Adjust delay between probes
- --min-rate <number>: Send packets no slower than <number> per second
- --max-rate <number>: Send packets no faster than <number> per second
- FIREWALL/IDS EVASION AND SPOOFING:
- -f; --mtu <val>: fragment packets (optionally w/given MTU)
- -D <decoy1,decoy2[,ME],...>: Cloak a scan with decoys
- -S <IP_Address>: Spoof source address
- -e <iface>: Use specified interface
- -g/--source-port <portnum>: Use given port number
- --proxies <url1,[url2],...>: Relay connections through HTTP/SOCKS4 proxies
- --data <hex string>: Append a custom payload to sent packets
- --data-string <string>: Append a custom ASCII string to sent packets
- --data-length <num>: Append random data to sent packets
- --ip-options <options>: Send packets with specified ip options
- --ttl <val>: Set IP time-to-live field
- --spoof-mac <mac address/prefix/vendor name>: Spoof your MAC address
- --badsum: Send packets with a bogus TCP/UDP/SCTP checksum
- OUTPUT:
- -oN/-oX/-oS/-oG <file>: Output scan in normal, XML, s|<rIpt kIddi3,
- and Grepable format, respectively, to the given filename.
- -oA <basename>: Output in the three major formats at once
- -v: Increase verbosity level (use -vv or more for greater effect)
- -d: Increase debugging level (use -dd or more for greater effect)
- --reason: Display the reason a port is in a particular state
- --open: Only show open (or possibly open) ports
- --packet-trace: Show all packets sent and received
