Accessing Zerotier’s REST API

Zerotier offers a powerful REST API that allows for seamless integration and management of your network. By default, the API is accessible on TCP port 9993. To securely interact with this API, an authentication token is required.

The authentication token is stored in the following file:

/var/lib/zerotier-one/authtoken.secret

To check if the Zerotier service is running correctly, you can use the curl command with the necessary authentication header. Here’s how to do it:

curl -Lv -H "X-ZT1-Auth: $(cat /var/lib/zerotier-one/authtoken.secret)" http://localhost:9993/status 2>&1|less

Breaking Down the Command:

• curl -Lv
  • -L: Follows any redirects the server might issue.
  • -v: Enables verbose mode, providing detailed information about the request and response.
• -H "X-ZT1-Auth: $(cat /var/lib/zerotier-one/authtoken.secret)"
  • Adds a custom header X-ZT1-Auth with the value of your authentication token. This is essential for authorized access to the API.
• http://localhost:9993/status
  • The endpoint to check the current status of the Zerotier service.
• 2>&1 | less
  • Redirects both standard output and standard error to less for easy reading and navigation of the output.
