Nmap says it needs admin. privileges so it can create raw packets to run
certain scans such as the SYN scan. Do the other scanning tools for example,
ISS Internet Scanner, Nessus, and eEye Retina, have the same issue? If so,
is there a sudo-like mechanism in Windows to run them with elevated
privileges but not under an admin. account? While I'm at it, any quirks with
the above tools I should know about?
