The bash shell contains pseudo-devices to send packets with TCP/UDP. The pseudo files are formatted like the following:
|
|
|
|
```
|
|
dev/tcp/HOST/PORT
|
|
/dev/udp/HOST/PORT
|
|
```
|
|
|
|
To send a UDP packet to `localhost:6300` containing the payload "Hello, World.", we would run the following command:
|
|
|
|
```bash
|
|
echo "Hello, World." > /dev/udp/127.0.0.1/6300
|
|
``` |
