======OpenNet======

An opennet, for Freenet purposes, is a network where connections are automatically created by the node. The node comes prepackaged with a list of seed nodes to which the node may connect. Once a connection is established between the node and the seed nodes, the seed nodes provide a list of more nodes to connect to, and they do they same, etc. This process happens continually while the node is running, without any user intervention.

====Security====

Though opennet is much easier for the user (compared to creating connections in a DarkNet), it is vulnerable to [[NodeHarvesting harvesting]], and therefore can be blocked very easily.

This was a known problem with Freenet 0.5, and it led to it being blocked by the [[GreatWall evil Chinese firewall]].

====Getting Started====

As of December 2007, trading darknet references with strangers on IRC has been deprecated. Running on the opennet requires a few simple steps:
~- Download [[http://downloads.freenetproject.org/alpha/opennet/seednodes.fref seed nodes]] and place the file in your node's directory.
~- Go to the Configuration page of your node, and enable the opennet switch ("promiscuous mode"). Note that opennet uses a different UDP port than darknet does. If you need to forward this port through your router, then do that.
~- Restart the node.
