I think i need to explain little more about the problem/situation..
Please note i am talking about desktop PC which will be used only by one user (say me).
I want a tool which will alert me(may be by opening a popup window) if some program tries to open a port(it may be a incomming or outgoing connection request) and it also prompt me for approval.If i approve(by providing su password) connection should be accepted automatically.
Presently i have the following senarion : 1. whenever i am going to execute some program which needs an open port it is dropped silently. 2. Then I am looking into the log and checking which port the program trying to open 3. Then I need to open the port manually from YAST Firewall 4. Then execute the program again For a desktop PC/laptop user I belive this is too much effort to run a simple IRC/messanger like program.
I also want alert message 1. if some one from a remote machine tries to connect my computer 2. if some one from a remote machine tries to run a port scanner on my ip
Does any one have any idea on how to do this??..I f anyone need any clarification please tell me i will clarify again if needed.
As far as I know, such a thing does not exist in Linux, not needed or wanted. If I'm not mistaken, you are describing a behaviour that is typical in windows, though. You could try programming it yourself (watching the logs, inserting the firewall commands...) About the alerting to outside attempts, they are simply logged, but tools like "snort" do extensive logging/alerting. - -- Cheers, Carlos E.
