RE: Passive OS Fingerprinting was Cisco CTR etc

Andy,

Let's get back to the topic.  I still have yet to figure out what the
difference between RNA and NeVO is ??

Mark,
Between you and I (& the rest of the list) I used CyberCop a few years
back and cut off an entire network.  Not, as you'd imagine, through
testing for DOS vulnerabilities but the shear weight of the traffic.
Learned a lot that day!  Also prompted me to create the distributed
scanners page.

 If I remember correctly many of the Cybercop scans contain the word
"cybercop" in the data of the packet allowing easy detection.  I'm
trying to think of an IDS that doesn't detect it and can't

take care

shame about the beer!
