Re: [freenet-support] Peer IP address leakage?

Hi,

My name is Michael and I'm currently studying the source code of Freenet.

I have found that the object reference for all PeerNode objects has the 
IP address of the peer associated with it. How is anonymity kept with 
the IP of the peer exposed? I have examined the log file and it seems 
the object reference of the peers are logged as they are added.


What I'm confused is since Freenet seek to promote freedom of speech in 
the presence of strict government control, if they decide to run a 
Freenet node and collect IP addresses in this manner, the consequences 
would be unthinkable


I have tested this by adding another node of mine and my IP address 
appears as expected.


Can anyone explain to me why??

Thanks,

Michael

Hi Michael...
it is correct that your IP would be known by your neighbour node, but, 
he is the only one to be able to identify you... more, and beside the 
fact of being able to be sure that you are using Freenet (only sure of 
this), even so, he has no way of knowing if the info or file or 
whatever, coming to you, or going from you, did or not come or go 10 
nodes away from you, since you act also (as a node) in passing 
packets... and anyway, even so, he is (and you are, and any of your 
neighbours) unable to know the content of the package, if you didn't 
create it yourself or ask yourself for it since only the original sender 
and final receiver are able to know it's content.

Hope it was clear...

People, this is NORMAL for all IP-based networks. You can not communicate
with another node unless you send a packet to it, and when you do so it CAN
be sniffed and analyzed. The only problem for the governments is that
although they CAN capture and identify freenet traffic, you are NOT doing
anything illegal by sending a packet to some random host. They can't read
the contents, and they can't be sure if you are downloading something or
just forwarding a request. So, unless they find something really illegal on
your harddrive you can be sure about your safety. However, you should take
appropriate measures for protecting your harddrive against inspections
(transparent encryption will do the trick - you just pull the power in case
of trouble, and all the data is totally secure unless you tell them the
password)
