Hi, I have a web proxy that can only initiate itself online, otherwise it would exit with an error. To daemonize that proxy, I wrote the following systemd service file: [Unit] Description=A Proxy Server After=network.target [Service] Type=simple ExecStart=/srv/proxy/aproxy/bin/main [Install] WantedBy=multi-user.target When the server is connected to the Internet, this service file can launch the proxy successfully, but it doesn't work on system startup, supposedly due to the lack of an connection with Internet access. So I need systemd to make sure the connect has been established before it launch this daemon. Regards.
