I just want to kill a specific tcp connection on my mac (similar to tcpkill on linux). By port or ip, preferably port but i'll settle. I don't want to pay for a service or download another software, I want the simple terminal command that will allow me to do this like tcpkill.
I've tried fixing up the rules on my firewall, and tried to make a bash script so it would run but to no success because the tutorial I found was very old.
Why does this seem to be such a difficult task to find information on, or do?
