That addresses the size issue, but what about the range?
According to the IANA (http://www.iana.org/numbers.html)
port assignments are as follows:
The Well Known Ports are those from 0 through 1023.
The Registered Ports are those from 1024 through 49151.
The Dynamic and/or Private Ports are those from 49152 through 65535.
So a range of 51024 to 54999 would be OK to use.
There are hundreds or thousands of services registered
in the current Linux range.
