[Snort-users] WinPcap 3.0 supports remote capture

Agreed!

I've been toying with a couple concepts, mostly for remote servers/lan's,
where, in order to see the actual packet, you have to login to the triggered
sensor and retreive it. This seems to be a first step in being able to
produce a complete picture in a centralized location from many remote
locations.

My initial scenario was a SOC in 'Company HQ' and many sensors at remote
locations, with no remote expertise to manage them. This scenario would
still have remote sensing, but still allow the centralized SOC to have the
info at their fingertips instead of having to do a remote login, or walk the
local admin through picking the relevant files from the sensors.
