Choosing a well know port number

Bob Rundle

7/8/2004 2:29:00 PM

Here's a simple question:

I'm building an application that will have a wide deployment in a specific
industry. I am using .NET remoting and will need to assign a few well known
port numbers.

At the present moment I'm using 8080, 8081, and the rest of that
foolishness.

How do I choose a a port number that is unlikely to conflict with other
apps? Is there some way to register my well known port number?

Your generally pretty safe in the upper 1000''s as there are few custom
apps that use custom port numbers in real enterprise environments.
Its always a good idea however to let people configure the port to
meet their speicfic enterprise needs.

Well...I am writing a custom app for a real enterprise environment. Your
note makes me think that I have overlooked something very basic. Is there a
set of well know ports I should be choosing from? I know there is an RFP
which lists all the well know ports. Should I find my way onto this list?

You may find the following web pages useful:

http://www.tcpipguide.com/free/t_TCPIPApplicationAssignmentsandServerPortNumber...

Also, You could try to connect to the port before starting your server
to see if any other application is running there. -- Bud

Thanks. This is exactly what I was looking for. I submitted a request for
a user port to iana.org.
