The previous port popularity had dupes in it. I wrote the code for
dropping duplicates today, and made another scan with the new code.
Here are the results:

On another thread, I was discussing precise scanning of publicly
advertised quake3 servers. The other part of the story involves
detecting and scanning quake3 servers upon stumbling on an open port
during a regular port scan. It seems there is no ultimate default port
for running a quake3 server. However, some ports are more common,
presumably some of them are default configurations of some server
software. Below are some statistics I gathered today regarding the
amount of servers using a specific port number. Now the open question
is, which port numbers should I include in the port rule? The options
might include 1) all of the ports 2) anything used more than once 3)
anything used more than, say 10 times 4) top-3 5) only 14445 6) none

 what do you think?, --Toni
