Description: Canaries running a Custom TCP service on all unused ports help detect any unexpected TCP connections, alerting you to potential threats even from a single stray connection, particularly in networks sensitive to such anomalies.
Log in to your Console.
Click on the Canary you want to configure the custom TCP service on.
Click on the gear icon (Configure Canary) to configure this Canary.
Scroll down to Custom TCP Service 1 and turn it on and enable Run this service on all unused ports.
Once you've made the changes you will then need to click on Deploy new configuration.
Note: This feature is not supported on Docker Canaries.
You're done! ;-)
