Server Setup and Installation of Software Dependencies

Run the install_server.sh script

sudo sh server/scripts/install_server.sh

Run npm install in the server folder

Create an ssl directory in the server folder Run the create-cert.js script

node create-cert.js

Copy the .env-template contents to a new .env file

Set the variables in .env:

• PORT
• SSL_PORT
• HOST_URL

Set the Elasticsearch url in the parsing scripts:

• iperfParse.py
• iperfUdpParse.py
• uptimeParse.py

Starting the Server

Run the start server script. This will start the node server, as well as iperf listeners for TCP and UDP connections

sh scripts/start_server.sh

Client Setup and Installation of Software Dependencies

Run the client installation script as root

sudo sh client/scripts/install_client.sh

If you haven't already done so, copy the .env-template file contents to a new .env file and set the variables as mentioned above.

Run npm install in the client folder

Starting the Client

Three options:

1. node client.js
2. Run the start client script sh client/scripts/start_client.sh
3. Edit rc.local to run start_client.sh at startup (best for when the probes are deployed, allows plug and play capability to deploy)
