+## peering with other nodes ##
+
+In order to actually be distributed, you need another person to sync posts with, otherwise what's the point right?
+
+Right now peering information is private, there is no link level authenticatio (yet) so everything is done via either a vpn tunnel or a tor hidden service.
+
+### Peering via cjdns vpn tunnel ###
+
+Set up cjdns, read more [here](https://github.com/cjdelisle/cjdns/blob/master/doc/configure.md#connection-interfaces)
+
+    git clone https://github.com/cjdelisle/cjdns
+    cd cjdns && ./do
+    ./cjdroute --genconf >> cjdroute.conf
+    ./cjdroute < cjdroute.conf
+
+Get your ipv6 address for cjdns
+
+    ip addr show tun0
+
+Edit srnd.ini to bind nntp on that ipv6 address, make sure to use the square brances `[` and `]`
+
+    [nntp]
+    ...
+    bind=[xxxx:xxxx:xxxx:xxx:xx....]:1199
+
+
+say you have 2 friends at fc33:3:3::aadd and fc03:9f:123::a3df. right now feeds.ini can't take raw ipv6 addresses so add them to `/etc/hosts`
+
+    # add these lines to /etc/hosts
+    fc33:3:3::aadd     bob
+    fc03:9f:123::a3df  charlie
+
+then add to feeds.ini the following:
+
+
+    [feed-bob]
+    proxy-type=none
+
+    [bob]
+    overchan.*=1
+    ctl=1
+    
+    [feed-charlie]
+    proxy-type=none
+
+    [charlie]
+    overchan.*=1
+    ctl=1
+
+then restart srndv2
