IP Networking

Hello all,

I am deploying an intranet web application. Its a war file. Can I use port 89 to enable the application for users? Is that port allowed? The application communicates via http on this nonstandard port

Thats a standard port used by "SU/MIT Telnet Gateway".

If at all we have to deploy applications on different ports what port should be used? I am not using websphere, I am using sun web server but I hope someone can answer this ...

My question again, if multiple web applications have to be used on different ports, what unix/window ports should be used? Are there any standard port numbers (such as any number after 1023 etc ..) that we can use?

Thanks in advance

Port is just a number used to distinguish between services (or used to locate apps within a remote host)
You can use any port u want, u just have to make sure their not in use by other apps ... and of course listening on reserved/well-known ports (<1023) requires your apps to have root privilege, if im right.

Also, if you want to look through a fairly canonical list of port numbers, the Internet Assigned Numbers Authority keeps one available here. You don't say what server you're using, but even for ports with an official assignment, as long as nothing else on your own system is listening on that port, there's no reason not to use it.
