- Start a listener on the specified TCP port and send a file into it:
|
|
|
|
`nc -l -p {{port}} < {{filename}}`
|
|
|
|
- Connect to a target listener on the specified port and receive a file from it:
|
|
|
|
`nc {{host}} {{port}} > {{received_filename}}`
|
|
|
|
- Scan the open TCP ports of a specified host:
|
|
|
|
`nc -v -z -w {{timeout_in_seconds}} {{host}} {{start_port}}-{{end_port}}`
|
|
|
|
- Start a listener on the specified TCP port and provide your local shell access to the connected party (this is dangerous and can be abused):
|
|
|
|
`nc -l -p {{port}} -e {{shell_executable}}`
|
|
|
|
- Connect to a target listener and provide your local shell access to the remote party (this is dangerous and can be abused):
|
|
|
|
`nc {{host}} {{port}} -e {{shell_executable}}`
|
|
|
|
- Act as a proxy and forward data from a local TCP port to the given remote host:
|
|
|
|
`nc -l -p {{local_port}} | nc {{host}} {{remote_port}}`
|
|
|
|
- Send an HTTP GET request:
|
|
|

`echo -e "GET / HTTP/1.1\nHost: {{host}}\n\n" | nc {{host}} 80`
