5-DRC INSIGHT - Validation and Testing


Purpose: Confirm COS is functioning properly before live testing begins.


Step 1 - Verify Services

sudo /opt/CentralOffice/node \
/opt/CentralOffice/setup/node_modules/forever/bin/forever -p /opt/CentralOffice list

Confirm all four are running:


Step 2 - Verify Ports

sudo ss -tulnp | grep node

Step 3 - Validate Local HTTP Response

curl -I http://127.0.0.1:55223
curl -I http://127.0.0.1:55224
curl -I http://127.0.0.1:55225

An HTTP 404 response at the root path can still indicate a healthy service.


Step 4 - Validate Content Directory

ls -lah /opt/CentralOffice/content_fs

The local content directory should populate after configuration is updated and content is downloaded.


Step 5 - Confirm DRC Portal Status


Step 6 - Validate Chromebook Access
