What your proposing isn't considered best practice. You might look at inetd, which can listen on a privileged socket and then hand that socket of to an unprivileged program.

Probably good advice if you are designing the program. If you just want to run a program that accepts a port as an argument, what would you do then?

@jontejj Just to make sure I'm clear, you're talking about a program that accepts a port number to listen on via the command line? I'd start by seeing if there was any way to use a non privileged port, to avoid needing root privs. There might be a way to use linux capability tools to assign just the right to open privilege ports when you run the program.

auth-bind seem to be the way to go for one-offs?

@jontejj I'm not familiar with it so I can't say.
