Yes Lee I am new to this OSS world and I agree that i am not a security expert.That is why i am trying to learn from the discussion made by experts like you.
But I can not agree with you on the point #1.
When one particular application will listen to a port, it totally depends on the application.
It may be during installation,may be during anytime the application wish.
I am totally agree with you Jim.

Is everyone getting my points what i wanted to say below.....
Have you been listening to the points others have made? Seems not.
-->Now he wants to listen a song.so he needs to run a player(say kaffaine or VLC or amarok etc)These players also needs some open port.
1) IF an applicaiton needs an open port, it is opened upon *INSTALLATION*, not use! 2) A mp3 player should not USE an open port, so select one designed properly.
So when ever he tries to run the application request is silently drops.
No, an application like that never gets installed, because the installer program [or person] in that situation is/was not capable of installing/creating a proper application. See #1 above.
--->Now he wants to chat/voice chat with some one using a VOIP messenger. but since this program also needs an open port.He cant do voice chat.
No, he/she CAN. See #1 above. It's fairly obvious that you come from the MS world, where either the applications lack good security design, is not installed properly, or 'add-on' software is being used (e.g. standalone firewall application). Security is fundamental to a good system installation, and it's simple with Linux. The fact that the MS world HAS no good security should not be fodder for a lenghty thread here.
