what port scanning program can I use

[Whoknow]

Hi Everybody!
what port scanning program that I can use to detect what port is currently openned on my PC and which program is using it , because my IIS can not run at port 80 (change to port 81 works fine), look like a program is using that port . I downloaded Nmap but I cant find the options to detect this . :confused:

thx a lots :)

netstat -a -b

Port 80 will be shown as http.

yes it's show as http , but how can I know what's the exec file using that port , because I dont have any webserver installed on my PC except IIS

Could it be that it isn't being used at all and that it's just closed? Could it have been disabled by default for "security".

I see on my W2K box here the netstat doesn't show the program. On XP it does.

For general security scanning system ports, ethical hacking and security exploits i use Nessus ... very good tool that gives you full reports and tells you what security updates you need.

If you just want a very simple port scanner try portscan ... I find its quite good

just downloaded the advanced-port : it does not show the exec file too (just show up as http).
I'll try Nessus to see if it works ,

thx anyway :)

hi wh666-666!
The Nessus works amazingly, I have figured out that skype's using that port for incomming connection , a big surprise to me :eek: , thx a lot :D
