Hey...wandering if there is a way to inspect packets coming in to determine what operating system the packets are coming from. Is this possible with a ASA 5510?

    Your only hope is CX, but if you are smart just get a Palo Alto and be done with it. : )
    Modularity and Design Simplicity:

    Think of the 2:00 a.m. test—if you were awakened in the
    middle of the night because of a network problem and had to figure out the
    traffic flows in your network while you were half asleep, could you do it?

    It can be done by using OS identifications, but you need to have the IPS module for the ASA 5500 series.

    You may be looking for something more automated, or real-time, but you can always use the ASA to capture a traffic stream (GUI or CLI), save it as a pcap file and then use p0f (passive OS fingerprint utility) to identify client OS. Or use nmap with the -O switch and target the unknown system(s) for an OS scan.

    * Provided you are in a lab and/or have permission to do so :)
