-b binary capture

[Greg Sarsons <gsarsons () home com>]

I see that snort by default with binary dump captures 1514.  Well this
is just to much for my little 30 Gig hard drive on a busy school
network.  I'm going to do some analysis with snort after but will also
be using tcptrace, ipfw and a few others.

If I grab 10%, say 150 vice 1514, will I really be limiting what I can
do after?  Doesn't tcpdump by default grab 68.

The traffic bw from what I know on the network has peaked at about
20Mb/sec but the average seems to be 11Mb/sec.  If I plug into another
smaller subnet the traffic bw could drop even more.

Again this has got to fit on a 30Gig drive.  The more days that I can
capture the better for the statistics.  Filling the hard drive in only
one day doesn't really give a nice look.

Any recommendations?

Greg
