Monitor network traffic and disable hardware when a threshhold in bytes is reached.

in the repo root run;

sudo ./Netlock/setup.sh

Note: if you experience issues after installation, please restart the shell (or open a new one)

Test if interface has a network connection

netlock -t interface

netlock -t en0

Disable all network interfaces

netlock -n

Enable all network interfaces

netlock -d

Monitor without limits

netlock -m interface bytes-out bytes-in

netlock -m en0

Monitor, disable network hardware when limit is reached

Note: The limit is defined in bytes.

netlock -m interface bytes-out bytes-in

netlock -m en0 5 5

Monitor, disable all network hardware when limit is reached

Note: The limit is defined in bytes.

netlock -m interface bytes-out bytes-in safe

netlock -m en0 5 5 safe

Monitor, clean output

will return an output of just the bytes, no formatting.

usefull for piping into other utilities.

netlock -c en0 out
