Engine Port Number Range

[Kathy Zwilling]

Does anyone know if there is a set range for the port numbers used by the engine processes.  I thought I had read once that this range was from 13,000 thru 13,500 but as I start up some new processes I am seeing process numbers in the 10,000 and 11,000 ranges in the engine logs.

My ultimate concern is to avoid using these ports to avoid potential conflicts.

Thank you!

If you’re running on AIX, run the following command:

no -a | grep ephemeral

This will return the settings for the tcp ephemeral range.  I believe the default range is 32768 to 65535.  These are the ports that are defined for OS processes.  It’s definitely a good idea to stay away.

Hope this helps.

kathy,

You must be remembering the host server ports.  The host server ports began at 13000 and the most recent port used is 13011 for Cloverleaf 5.4.  As New releases of Cloverleaf come out we’ll use the next port number.  It’ll take years to get to 13100.  So just pick something safely away from 13000, 13500 would be great.

Other than that the processes don’t use any specific ports that you have to worry about, they’re assigned by the os on demand.

Greg,

What I was looking at was the first part of one of our engine logs (see below snippet).  Do you see the where it says “Engine process is 6808 on host hp_intr” below?  This number was in the 10,000 and 11,000 ranges when I saw it the other day before we did our monthly bounce of the hp machine.  As you can see, now the number is lower.

We use ports for our connections in the 10,000 and 11,000 ranges so I was concerned.  What is the 6808 (in this case) and should I be concerned?  

Thanks,

Kathy

6808 is the pid, not the port for the process

Oh yes.  Thank you!  Probably should have been able to figure that out on my own!   😳  Thanks!
