Netcat is a versatile utility for working with TCP or UDP data.

More information: https://nmap.org/ncat.

  • Listen on a specified port and print any data received:

nc -l port

  • Connect to a certain port:

nc ip_address port

- Set a timeout:

nc -w timeout_in_seconds ipaddress port

  • Keep the server up after the client detaches:

nc -k -l port

  • Keep the client up even after EOF:

nc -q timeout ip_address

  • Scan the open ports of a specified host:

nc -v -z ip_address port

  • Act as proxy and forward data from a local TCP port to the given remote host:

nc -l local_port | nc hostname remote_port
