Acertains the remote operating system Detailed Explanation for this Vulnerability Assessment This script attempts to identify the Operating System type and version by various ways : - If the remote host is a Windows host, it will attempt to acertain its OS type by sending MSRPC packets on port 135 and guess the OS based on the results - If the remote host has an NTP client listening on port 123, this script will try to ask for the operating system version this way - Otherwise, this script acertains the remote operating system by sending more or less incorrect ICMP requests using the techniques outlined in Ofir Arkin's paper 'ICMP Usage In Scanning'. A possible hacker may use this to identify the kind of the remote operating system and gain further knowledge about this host.
