Ports Question

[Kevin Crist]

We have a spreadsheet that has all the ports our threads are using and it is rather old, predating me. There is a section that says ports 5000 and below are to be used for Cloverleaf use only. Is this still in effect or was it ever?

Thanks.

Kevin,

I don’t think that was ever a Cloverleaf mandate, but more likely an organizational mandate.  I believe I have seen mention of a recommendation to NOT use any ports below 9000 as those tend to be reserved for other things (not related to Cloverleaf).

ok, thanks. I appreciate it.

Vendors are now registering ports above 9000 as well. Here we have arbitrairly set our floor to 12000.

we had a vendor want to use 2575 and i told him we couldnt and made him change it to what i wanted. i was curious if that was technically true or not.

[James Cobane]

Technically, you could use port 2575 as long as it is not conflicting with something else.  It is dependent on who is the client/server and whether or not the port is already in use on the ‘server’ machine.  From http://www.iana.org ( http://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.xhtml?search=hl7 ), port 2575 is registered as reserved for HL7, so this is likely where the vendor was coming from.
