|
|
|
|
|
|
|
`sudo socat OPENSSL-LISTEN:4433,reuseaddr,cert=./cert.pem,cafile=./ca.cert.pem,key=./key.pem,verify=0 STDOUT`
|

|
|
|
|
|
|
|
- Create a connection to a host and port, transfer data in STDIO to connected host:
|
|
|
|
|
|
|
|
|
|
`sudo socat - TCP4:www.example.com:80`
|
|
|
|
|
|
|
|
|
|
- Forward incoming data of a local port to another host and port:
|
|
|
|
|
|
|
|
|
|
`sudo socat TCP-LISTEN:80,fork TCP4:www.example.com:80`
|
|
|
|
|
|
|
|
|
|
- Send data with multicast routing scheme:
|
|
|
|
|
|
|
|
|
|
`{{echo "Hello Multicast"}} | socat - UDP4-DATAGRAM:{{224.0.0.1}}:{{5000}}`
|
|
|
|
|
|
|
|
|
|
- Receive data from a multicast:
|
|
