Sometimes I have scripts that automatically assign ports starting from 30000. How would that work? Would I have to bind to port 0 multiple times until I randomly get a port in that range?

I’m not exactly sure if that’s the question, but the range can be set. Here’s the Linux solution: https://tldp.org/LDP/solrhe/Securing-Optimizing-Linux-RH-Edi... FreeBSD has net.inet.ip.portrange

I saw the URL and immediately thought it was about Acid Pro DAW or Vegas video editor is used to use back in the early 00’s.

I'm not sure how I'd do acceptance/E2E testing without the magic of port 0. As long as you have a way of capturing what port it ended up using (which most languages are able to out of the box more or less), parallelizing testing workloads becomes such a breeze without having to manage ports and all that jazz, just fire everything up with N parallism and let the OS figure out what the free ports are, pass the references down and stuff just works. Thanks Linux :)

And then there is OpenSSH...

    joker@joker:~$ ssh localhost -D 127.0.0.1:0
    Bad dynamic forwarding specification '127.0.0.1:0'
    joker@joker:~$ ssh localhost -D 127.0.0.1:9999
    ssh: connect to host localhost port 22: Connection refused
    joker@joker:~$ ssh localhost -L 127.0.0.1:0:localhost:8080
    Bad local forwarding specification '127.0.0.1:0:localhost:8080'
    joker@joker:~$ ssh localhost -L 127.0.0.1:9999:localhost:8080
    ssh: connect to host localhost port 22: Connection refused

Oh well.
