I am running Ubuntu 9.10 Server and am collecting packets with
TShark 1.4 from about 40 Subnets (Offices) traversing my aggregation
Subnet (the Datacenter). There are 9000 64meg files collected per day
before overwriting begins. When a Network question arises, I copy the 1 to
3 hours of files to a 2nd Directory so that they won't be overwritten
later. That's about 180+ 64 meg files.
I need to filter all of the files in the 2nd Directory to create new
files only containing packets from 1 to 4 transmitting or receiving
Subnets. I need all of the IPs from each subnet.
Next, want to see the "Top Talkers" during this period. That should
be the easy part.
I presume grep, bash, awk editcap, tshark, tcpdump are the tools. Can
someone get me started with some scripts / examples?
