This note records the notes that need to be set when using Ubuntu daily. systemd-networkd-wait-online.service systemd-networkd-wait-online.service is a service unit of Systemd, mainly used to wait for the network connection to be ready when the system starts. Function: This service will wait for systemd-networkd to complete the network configuration and confirm that at least one network interface is online before it is marked as ready, allowing other network-dependent services to start. By default, it monitors all network interfaces managed by systemd-networkd until the connection is successful or times out. ** FAQ **: If DHCP takes a long time to obtain an IP, the system startup may be stuck in this service; when there is no network connection, it may also wait until it times out. ** optimization method **: You can adjust the timeout, disable services, or check the network configuration. Adjust timeout Set TimeoutStartSec to 2sec: ...

Imagine a self-hosted Cloudflare tunnel. Pangolin uses Traefik under the hood for the actual HTTP proxy. The Badger plugin provides a way to authenticate each request using Pangolin. The second service, Gerbil, provides a WireGuard management server that Pangolin can use to create peers to connect to. Finally, there’s Newt, a CLI tool and Docker container that connects to Newt and Gerbil entirely in user space via WireGuard and proxies your local resources. This means you don’t need to run a privileged process or container to expose your service! ...
