hey guys. I need a simple mac os x program that shows all the open and closed ports on a network. so if you guys can point me to a good program that would be great thanks.
do you need something more advance than the scan tool inside of Network Utilities (inside the Applications->Utilities folder)?
Are you looking to watch your own port activity or the active ports of another computer? There used to be a program, I think was called Ctanide but I couldn't find it anywhere, that would do all sorts of crazy port things. But I'm not sure if it is still around, since it could be used for a DOS attack pretty easily.
