About

6       Since  several  years I used to use a own repository of scripts to ana‐
7       lyze network traffic. First I started  with  plain  tcpdump,  tcptrace,
8       tcpslice,  tcpstat  and  the other tools. After some years I started to
9       wrote an own set of scripts, starting with Perl  and  later  also  some
10       Ruby  scripts. Before I forget, of course, a few C programs are also in
11       the collection. Captcp is the attempt to rewrite the scripts in Python.

18       sure, but eventually there are some tricks for you.

20       ·   Don´t capture data life - capture the data via tcpdump and  analyze
21           the data off-line
22
23       ·   If you know what you want to analyze you can adjust tcpdump to cap‐
24           ture the required data
25
26       ·   Make backups of your traces
27
28       ·   Don´t use one tool, find the most useful tool for your requirements
29
30       ·   Last but not least: question the results!

Modulse Overview

35       The script functionality is splitted into submodules. Similar  to  git,
36       perf  and  kvm-tool.  The  following list provides an overview over the
37       currently supported list. If in doubt you can call captcp  without  any
38       argument to get the full list.
