Who owns this port
There are many utilities in linux which check for owners of linux port numbers. Ports that are under number 1024 are reserved for common services and are assigned to root. Everything above everyone can use. Root and all other linux users. You can use 65k ports in linux so that is more than enough and you should not be worried about that.
Netstat is very usefull utility which shows opened ports and users in linux who uses them ( who is connected to your linux system )
Use Netstat like this :
netstat -an | more
It will show you who is connected to which linux service.
Another utility that is very useful in linux is FUSER.
when you type : fuser -v -n tcp 5000
linux will output which user owns a port 5000.
