From flud

[edit] Semi-Private flud Networks

1. Start flud on the first computer:

   > fludnode

   Note the IP address of the first computer (if the computer is behind a firewall/nat, you'll need to forward ports. Otherwise, find your ip address via 'ifconfig eth0' or any other preferred means).
2. Start flud on a second computer, with the first computer's ip/port pair:

   > fludnode [IP address of first node] 8080

   (if you have modified the listen port in ~/.flud/flud.conf, change 8080 above appropriately)

Viola! they are connected. You can connect more machines using the same process.

You can now backup files through either 'fludclient' (while also running 'fludscheduler') or 'fludlocalclient'. You can also get a list of all the known nodes in 'fludlocalclient' via the 'nodes' or 'buck' commands.

[edit] Fo' Realz Private flud Networks

The above method will not prevent unknown flud nodes from connecting to the network, so if you are running your fludnodes for prolonged amounts of time, you'll want to disallow this. In order to shut out flud nodes that you haven't invited, simply change the value of 'groupidr' in ~/.flud/flud.conf (or $FLUDHOME/flud.conf if you've modified FLUDHOME)

Only nodes that have the same groupidr will be able to backup/restore to each other.

Note: the configuration of the shared-secret groupidr will be automated in future releases.
