Thanks for staying with me.
I did sudo. Is that not good enough?

As far as I know you need to be root to run tcpdump, and it's not
because of the program but because the program needs to access the kernel.

Estani, thank you so much for getting me started. That was Great Help !
but now:
The Script ran perfectly with the obvious changes needed !
I new the Script was working, B U T, tcpdump comes back with Permission
Denied. I chmod to 777 and 755 with no effect.
I ran it on Ubuntu 9.10 and 10.04, same results. I googled it and did the
9.04 fix and it didn't fix it.
(aa-complain /usr/sbin/tcpdump - This will change it to complain)
(aa-enforce /usr/sbin/tcpdump - This will renable the AppArmor
profile
for tcpdump)
When I changed the Script to use tshark it ran perfectly and gave good
results.
What do I do to fix tcpdump on Ubuntu?

Hi Phil,
I think you could use something like:
for file in second_dir/*; do
tcpdump -r $file src net a.a.a.a/x dst net b.b.b.b/y>>
$file.filtered
done
You could join all resulting files for a given amount of time with
tcpslice if that simple append does not do the trick.
I haven't tested this out, but it should give you a clue as to where to
go from this point.
Cheers,
Estani

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?
