![OpenVPN 服务已启动但未监听](https://linux22.com/image/123262/OpenVPN%20%E6%9C%8D%E5%8A%A1%E5%B7%B2%E5%90%AF%E5%8A%A8%E4%BD%86%E6%9C%AA%E7%9B%91%E5%90%AC.png)
编辑:检查 udp
netstat -upnl
我尝试遵循这两个指南https://linuxconfig.org/how-to-setup-a-vpn-with-openvpn-on-debian-9-stretch-linux和https://www.digitalocean.com/community/tutorials/how-to-set-up-an-openvpn-server-on-debian-8使用 debian 8 和 9。
我可以启动 openvpn 服务并根据它正在运行的状态命令,但 openvpn 没有监听。
# netstat -ntlp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name

tcp6 0 0 :::22 :::* LISTEN 3768/sshd
根据日志看起来有几个错误。我究竟做错了什么?
