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.
