If you configured cloudflared with your own service files ¶ The procedure for updating depends on how you configured the cloudflared binary. You can either do this manually, or via a cron script. However, you should keep the program update to date. The cloudflared tool will not receive updates through the package manager.

Configuring DNS-Over- HTTPS ¶Īlong with releasing their DNS service 1.1.1.1, Cloudflare implemented DNS-Over- HTTPS proxy functionality into one of their tools: cloudflared. What is DNS-O-Matic DNS-O-Matic is a free service for distributing your dynamic IP changes to multiple services with a single update. It is worth noting, however, that the upstream DNS-Over- HTTPS provider will still have this ability. This means that the connection from the device to the DNS server is secure and can not easily be snooped, monitored, tampered with or blocked. This means that not only can a malicious actor look at all the DNS requests you are making (and therefore what websites you are visiting), they can also tamper with the response and redirect your device to resources in their control (such as a fake login page for internet banking).ĭNS-Over- HTTPS prevents this by using standard HTTPS requests to retrieve DNS information. With standard DNS, requests are sent in plain-text, with no method to detect tampering or misbehavior.
