Re: Let's talk about Distance Sniffing/Remote Visibility

I'd like to hear from the list as to what your preferred means of
determining what the hell is going on at a packet level at the other side
of a WAN/MAN/frame/etc link.
Another commercial product to consider may be netIntercept from Sandstorm (www.sandstorm.com). They came out and talked to BayLISA (www.baylisa.org) about this a short time ago, and while it isn't yet doing the line rates talked about here, it was interesting. It's more about demultiplexing TCP and decoding protocols without regard to the port number; sort of an expert-system. (I saw it pluck out and display thumbnails of images from a gzipped tar file that was FTPd on a high port, IIRC.)

It's a FreeBSD box already built and already tuned. If I had the money, I'd have bought one on the spot.
