# nmap
Network map

```
Network exploration tool and security / port scanner.Some features only activate when Nmap is run with privileges.More information: https://nmap.org.

 - Check if an IP address is up, and guess the remote host's operating system:
   nmap -O {{ip_or_hostname}}

 - Try to determine whether the specified hosts are up and what their names are:
   nmap -sn {{ip_or_hostname}} {{optional_another_address}}

 - Like above, but also run a default 1000-port TCP scan if host seems up:
   nmap {{ip_or_hostname}} {{optional_another_address}}

 - Also enable scripts, service detection, OS fingerprinting and traceroute:
   nmap -A {{address_or_addresses}}

 - Assume good network connection and speed up execution:
   nmap -T4 {{address_or_addresses}}

 - Scan a specific list of ports (use -p- for all ports 1-65535):
   nmap -p {{port1,port2,…,portN}} {{address_or_addresses}}

 - Perform TCP and UDP scanning (use -sU for UDP only, -sZ for SCTP, -sO for IP):
   nmap -sSU {{address_or_addresses}}

 - Perform full port, service, version detection scan with all default NSE scripts active against a host to determine weaknesses and info:
   nmap -sC -sV {{address_or_addresses}}
```
