Java

To run this Java application, from a working directory with the src/peerbase folder in the Java classpath, type

java -cp ... peerbase.sample.FileShareApp <my-port> <peer-port>

The peer node will be launched listening on <my-port> and will attempt to connect/register with a peer at <peer-port>. (Obviously the first peer created will not have a valid <peer-port> to connect to - just put anything.)

Files will actually be transferred from one peer's working directory to another if they exist as named.

Python

(Written for Python 2.x.)

To run the demo Python application:

python filergui.py 9001 10 localhost:9000

In general,

filergui.py <server-port> <max-peers> <peer-ip>:<port>
