Re: analysing captured packets

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

Hi
Thanks for the suggestions, looks like I'll be busy for a while. Don,
your papers look good I'll have a read through.

I've also had a look at the honeynet challenges and this one is the
one for beginners and packet analysis
http://www.honeynet.org/scans/scan23/ , from a quick look at the top
answer, he has come up with a very detailed analysis of the file. So I
know where I'm aiming, how long would people suggest that it would
take to get to this level of knowledge? The person answering says he
is a beginner but from his answer he is obviously a better level of
beginner to me! Obviously this depends on background and how much you
study, but is the person answering the questions likely to have a
months worth of experience or 6 months? When studying on my own I'm
always my own worst critic and feel that I'm picking things up too
slowly!

And pagvac, I will be, I just wish there were more hours in the day!

Thanks

Robin
