Re: What Port Should I Use?

That's really the crux of the matter, isn't it.

If I start up my server using a port in the dynamic/private range then I
run the risk that the port is already in use by some client on the same
host. When the client started, the tcp stack would have dynamically
assigned it a port and that just might be the one that I want my server to
listen on. So this doesn't seem like a good option. This leaves me with
ports in the well known or registered ranges.

But if I want to adhere to standards what port do I use? IANA says that
the well known and registered ports shouldn't be used without
registration. And my server is using a proprietary protocol that I
really don't have any need to register.

The only choice I seem to have is to not adhere to standards. The
conclusion I've come to is to use a port somewhere in the registered
range.

Thanks
