I'm working on a debian-based system and am still learning about systemctl vs service, but am trying to use my
openvpn configuration as a use-case for working through this.
In my current setup, I'm really confused as to how
openvpn appears to be starting on boot and how to manage them.
On boot, these are the
openvpn processes that have been started:
> ps aux | ag 'openvpn' nobody 952 0.0 0.0 5800 1108 ? Ss 13:29 0:00 /usr/sbin/openvpn --daemon ovpn-server --status /run/openvpn/server.status 10 --cd /etc/openvpn --config /etc/openvpn/server.conf root 1537 0.0 0.1 6088 2544 ? Ss 13:30 0:00 /usr/sbin/openvpn --daemon --auth-nocache --config /root/.vpn_conf/pia.ovpn
I still don't know what's controlling these to start on boot.
The first proc is the server (which I wish to disable), and the other is the client which I wish to keep and continue to use.
My understanding is that one can use
systemctl to list all services:
> systemctl list-unit-files --type=service | ag 'openvpn' openvpn.service disabled openvpn@.service disabled
What are the differences between these two? Are these the two services controlling the processes above? If they are disabled, why are they still starting on boot?
If I try and use
service to get the status of
openvpn, I get:
> service openvpn status ● openvpn.service - OpenVPN service Loaded: loaded (/lib/systemd/system/openvpn.service; disabled) Active: active (exited) since Sun 2017-02-19 13:29:51 PST; 18min ago Process: 936 ExecStart=/bin/true (code=exited, status=0/SUCCESS) Main PID: 936 (code=exited, status=0/SUCCESS) CGroup: /system.slice/openvpn.service Feb 19 13:29:51 systemd: Started OpenVPN service
Which prompts me to ask:
If there are two entries in systemctl for openvpn, what is the second one called when using
service openvpn_2nd? status?
Just in case, there is a
Any insight into some of the questions above would be greatly appreciated.
