kademlia netty standalone test

Simple CLI application written using Spring Shell for Kademlia Netty.

How to use:

First, download the jar file from releases or build the project yourself using mvn:

mvn clean package

Run

First, run the jar file:

java -jar path/to/appliaction.jar

You will get spring shell:

shell:>

Now, serve (start) your first node by entering the shell command serve and pass id, host and port of the current machine:

shell:> serve --id 1 --host 127.0.0.1 --port 8001

expected output:

2022-11-25 15:02:52.132  WARN 40382 --- [           main] io.netty.bootstrap.ServerBootstrap       : Unknown channel option 'SO_KEEPALIVE' for channel '[id: 0x2ef03ff4]'

Started node

Run the application in second server or machine (surely works on local too) and bootstrap it with first node:

shell:> serve --id 2 --host 127.0.0.1 --port 8002 --bootstrap 1:127.0.0.1:8001

Format of bootstrap node data is: id:host:port.

Store and lookup

After running your nodes, you can start storing and looking up for data in any of the machines:

shell:> store key value

shell:> lookup key

Stopping application

Before stopping the application run stop in all nodes:

shell:> stop

And then enter exit command to exit the shell.
