> Netcat is a versatile utility for working with TCP or UDP data.
|
|
|
|
- Listen on a specified port and print any data received:
|
|
|
|
`nc -l {{port}}`
|
|
|
|
- Connect to a certain port (you can then write to this port):
|
|
|
|
`nc {{ip_address}} {{port}}`
|
|
|
|
- Set a timeout:
|
|
|
|
`nc -w {{timeout_in_seconds}} {{ipaddress}} {{port}}`
|
|
|
|
- Serve a file:
|
|
|
|
`nc -l {{port}} < {{file}}`
|
|
|
|
- Receive a file:
|
|
|
|
`nc {{ip_address}} {{port}} > {{file}}`
|
|
|
|
- Server stay up after client detach:
|
|
|
|
`nc -k -l {{port}}`
|
|
|
|
- Client stay up 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}}`
