[gentoo-user] unencrypted network tools

How can I see what is happening as far as traffic on my unencrypted
network?  How can I keep my own http traffic private?

Use https instead.  IPSec is another option, if supported.  Also, 
traffic is normally only passed along the links between you and the 
server, unless there's some hub between you can them.

You may be able to anonymize normal http by using tor.  I think freenet 
also provides some level of anonymity and encryption for http, but I've 
never used it.

ntop is a good network summary program too. Works good if you can run it on 
your default gateway machine. tcpdump is pretty cool for sure.

You can only use https on servers that support it. The question is too vague 
to answer without specifying from who do you want to keep the data private? 
Just people on your local network? Your ISP? Your boss? The http servers?

The network is just run from a router.  No server on which I can run
that stuff.  Is there anything I can use from my workstation which is
connected to the network?

I'm only trying to keep the data private from the other people on the
local network.

You can run it on your workstation as well and you will see broadcast traffic 
and traffic going to your computer. If you are on a hub, you should see all 
traffic connected to the hub.

Who administrates your router and/or network? What kind of router is it? Are 
you using a swtich? Assuming you have a basic network setup using a simple 
switch and a simple router you would generally be private for outgoing http 
traffic unless there is someone sophisticated enough to be running something 
like ettercap to confuse the switch.

If you have no idea and if you have a remote computer you can connect to for 
browsing (maybe something at your home or elsewhere) you can remote control 
into it (using ssh tunnels for encryption) and then browse privately from 
that machine.

Are you expecting the other hosts on your network to be monitoring your http 
traffic? If there is some suspected method of them monitoring you it may 
require a specific technique to avoid their monitoring.

In any case, where does "gentoo" fall into this whole deal? This is a gentoo 
list.

There is just a $50 router.  It's just a network at my housing complex
that everyone connects to.

I remember one of my buddies showed me how he could drive around a
residential area and see what people were doing on their unencrypted
networks as he passed by.  I'd like to protect myself against that
kind of intrusion and also take informational advantage of those that
don't.

I'm looking for Gentoo tools.
