Basically I'm trying to figure out how Nessus determines a host is 'alive' and then if it is alive, how does it determine if a port is open or not. It's not for me, it's for a vendor that is being rather 'difficult'.
You might look in Chris McNab's book "Network Security Assessment" (O'Reilly). Chapter 4, "IP Network Scanning", probably has what you want to know. BobS Oh, I have absolutely no connection with O'Reilly. I just own a copy. _______________________________________________ Nessus mailing list Nessus@list.nessus.org http://mail.nessus.org/mailman/listinfo/nessus
