TCP/UDP with Bash 2020-05-25T23:10:15-04:00 false
Bash
Networking

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:

echo "Hello, World." > /dev/udp/127.0.0.1/6300
