Assigned Ports Command

You are only allowed to use the ports that are assigned to your service.

Your Ultra.cc service comes with a range of ports that are allocated to each of the applications available for installation via the User Control Panel. In this guide, we will show you the app-ports command and how to use it.

Once you have successfully logged in to your Ultra.cc service, you may execute the following commands:

app-ports show – List ports and their application allocation.
app-ports free – List unallocated ports that can be used for custom applications.

Furthermore, custom applications can be assigned a port that you are currently not using. For example, any port that is listed when you execute app-ports free can be used for a custom application of your choice. Using any port outside your allocated port range is strictly prohibited, and will put you at risk of a violating our Fair Usage Policy.
