A simpleminded google search got this.
> A couple technical questions regarding Linux have come up on

> 2] What is the theoretical maximum number of sockets that a single
> process can listen and respond on?

> The two, as you might imagine, are connected. I need to respond to
> possible input from up to a thousand different ports, and spawning
> a process to listen on each isn't working - probably too
> many processes. But if I have a program listen on 10 sockets, can I
> respond fast enough? How about 100? All the sockets won't be in use
> at the same time, but I never know which ones exactly are needed.
> Perhaps I need to do something like inetd, and just listen on a
> bunch of sockets and spawn off the process to handle the input
> when needed?

> Thanks for any advice and/or web resources you can point me to.
