Please bear with me...
I've got a Windows 2000 web server that is spewing out over 2Mbps of
data which is going out round robin over my 3 T-1 connections.
Although there is still more throughput available, this is seemingly
rediculous.
I've got a fortigate box in front of the server now, but the details
it gives aren't quite what I need. What I'd like to have is a FBSD
filter (transparent bridge) setup in front of the box, with software
that can chart for me what type of packets are being sent/rec'd
to/from this box, as well as each packets frequency and size. Any
graph would do.
I believe this is legit HTTP traffic, but I can't identify packet size
(or the size of a single entire HTTP session etc). Seeing this in
graphical form would help me immensely.
Anyone familiar with available software that I could dump on my filter
box that can potentially do something similar like I am looking for?
I was contemplating on asking this on -ipfw, however technically it's
not a direct IPFW question.
Tks everyone for any suggestions.
Steve

You may want to check out Ethereal (free packet sniffer)
www.ethereal.com. I have used this successfully on FreeBSD. Also,
FreeBSD has a program called tcpdump that will show packets without the
added bells and whistles of Ethereal. One note: if you are using level 2
or higher switches, the sniffer will not pickup all the traffic coming
out of your Win2k box unless you configure a management port on your
switch or use a hub with both the sniffer box and the server connected
to it.
Alternatively, you may be able to run Ethereal on you Win2k box....
Hope this helps.
