- bin
  |- kcn
  |- kcnd
- conf
  |- kcnd.conf

File Name	File Description

bin/kcnd	CN start/termination script file
conf/kcnd.conf	CN configuration file

Installation

The installation is the uncompression of the downloaded package where you want to install the package.

$ tar zxf kcn-vX.X.X-linux-amd64.tar.gz

Or,

$ tar zxf kcn-baobab-vX.X.X-linux-amd64.tar.gz

Note: it is recommended that the uncompressed directory kcn-linux-amd64/bin path should be added to the environment variable $PATH to run the kcn and kcnd globally. As an example,

$ export PATH=$PATH:~/downloaded/path/kcn-linux-amd64/bin

The other sections assume that the path is added to the variable.
