Is a local port scanner necessary?

Is it necessary or useful to have a local port scanner if you use a properly configured firewall?  Is it redundant or does it provide an extra layer of security?

 

            IMHO a port scanner is an essential security program when used properly.   not everyone has the same needs so this may not apply to the average user.

            so just maybe the answer depends on your needs.  what goal would you being trying to achieve...etc.  if its just a matter of wanting to see if you have any ports open then a simple online scan would do the job.......without the need for installing yet one more program...."memory" is precious!   plus, there is also "resource useage" to consider.  

          a word of caution I would respectfully offer to anyone....is never try playing games with a hacker...if you are experiencing abnormal scans..pings...etc...shut-down...an let your computer live for another day....don't challange a hacker by pinging him back....that may only just tell him that ..yes, you are there....an perhaps give him your address......

Thanks snowman.  I just want to make sure that all ports are closed and that my firewall is operating properly.  I'm not sophisticated enough to play games with hackers.  I have used the Gibson site to test ZA and it says I am stealthed.  But the test only covers a limited number of ports.  Is a more comprehensive test necessary and available?

 

You can let this site do a scan:

And here you can find more portscannings:
