More On Detecting NAT Gateways

Posted by timothy on from the check-your-terms-of-service dept.

tcom91 writes "The Slashdot article Remotely Counting Machines Behind A NAT Box described a technique for counting NAT hosts. A recently published paper Detecting NAT Devices using sFlow describes an efficient way of detecting NAT gateways using sFlow, a traffic monitoring technology built into many switches and routers. This technology could be used to enforce single host access policies and eliminate unauthorized wireless access points."

    Slashdot didn't describe how to count machines behind a NAT. AT&T Research did. Nice try to steal credit, though.

    From where I'm sitting, your SQL is syntactically invalid.

    > Karma: SELECT `karma` FROM `users` WHERE `userid`=138474;

    is incorrect. It should be:

    SELECT karma FROM users WHERE userid='138474';

    Sorry :P

    Cheers
