openvpnইউনিট ফাইল ExecStart=থেকে সঠিক কলটি ব্যবহার করে কমান্ড লাইন থেকে সূক্ষ্ম শুরু হয় systemd:
/usr/sbin/openvpn --daemon ovpn-server --status /run/openvpn/server.status 10 --cd /etc/openvpn --script-security 2 --config /etc/openvpn/server.conf /run/openvpn/server.pid
ps ax প্রক্রিয়াটি রয়েছে তা নিশ্চিত করে:
1634 ? Ss 0:00 /usr/sbin/openvpn --daemon ovpn-server --status /run/openvpn/server.status 10 --cd /etc/openvpn --script-security 2 --config /etc/openvpn/server.conf --writepid /run/openvpn/
তবে systemctl start openvpn@serverসফল নয়:
