Re: analysing captured packets

["Robin Wood" <dninja () gmail com>]

Thanks all.

I'm going to have a look through these as they should give me a good
base. The reason I want to learn about this is I'm getting into
wireless pen-testing and so will need to analyse the data I capture
during tests. So I'm not actually looking for analysys of attacks,
more higher level captured data, things like re-building emails,
watching windows domain logins that kind of thing.

Obviously, the same high level data flows over wireless as over wired
so techniques for either would help.

I should have been more specific when I posted my original question.
