That is wrong. CentOS 5 is at Update 11. Not keeping up to date with releases is a cause for concern because it is a sign of poor security and maintenance standards. I suggest you verify the integrity of that machine, and any adjacent machines lacking updates, and update before doing anything else.

First of all this seems to be a continuation of
this thread of yours that you never responded to back then. That is not efficient. Secondly business_kid offered a list of port numbers to use. You should be as complete and list the ports you have checked and show you have logged traffic on those ports to verify they were in use (or not) by this application. Next to that he also hinted at ports possibly having changed which you may or may not have researched or checked.
So. If you haven't done so then this is the point where you set up a subnet for testing purposes, configure traffic logging and show us the result of running the application within that subnet to verify which ports are in use (or not) by this application.
