    Default port scan to find systems without a certain port open?

    Does anybody know of a tool or technique to find systems that do not have a specific port open? I am wanting to find systems on our corporate network that do not have port 8081 open. This signifies to me that it doesn't have McAfee EPO Agent and perhaps not A/V.

    If you use nmap with
    Code:
    -p 8081 --open 8081
    would list all the hosts with 8081 open then you could do a reverse diff or grep against a list of all the hosts within your target IP space.
    I'm a compulsive post editor, you might wanna wait until my post has been online for 5-10 mins before quoting it as it will likely change.

    I know I seem harsh in some of my replies. SORRY! But if you're doing something illegal or posting something that seems to be obvious BS I'm going to call you on it.

    I will just use the --open feature. The results of the scan clearly show a host is up, but not the port open. thanks.
