port number

[TheDash]

Hello,

I am configuring an intranet web application. Can I use port 89 to enable the application for users? Is that port allowed? Otherwise, can you please suggest one?

Thanks

Hi,

Above port is called "SU/MIT Telnet Gateway". Port 80 is already used by another application. Is 89 allowed to use in the intranet under a firewall?

Hi,

If you take a look at the Well Known Port list at

http://www.iana.org/assignments/port-numbers

you can see that port numbers 0-1023 are assigned by IANA.
Portnumbers above 1024 are somewhat free to use.

You can use port 89. As long as you don't have a SU/MIT TelnetGateway which already uses this port.

When the other application that uses port 80 is running on the same server as your intranet application, then you must use a different port (89).
If you service the intranet application on a different machine you can use port 80 for it. It will not interfere with the other application that uses port 80.

Another port commonly used when port 80 is unavailable is port 8080.

although in a lot of cases port 8080 is also used for proxy servers (I have seen this in a number of different companies now).

The real world is not about exam scores, it's about ability.

You can run both websites on port 80 by configuring virtual servers. This is how hosting services do it. A required component of HTTP/1.1 is the Host= tag, which indicates the name of the site that was requested. The web server uses that to determine which web site to serve.
