Hi!

Just recheck file locations for .pem .crt and .key files.
Files are probably in wrong folder.

I am having a similar to OP.

My error is as follows:

[oconf=]
[root@Centreon-Central openvpn]# sudo openvpn --config /etc/openvpn/server.conf

Options error: Unrecognized option or missing parameter($) in /etC/openvpn/server.conf:305: □kd□kd□kd□kd□kd□kd□kd□kd□kd□kd□kd□kd□kd□kd□kd□kd□kd□kd (2.3.12)

Use --help for more information.

[root@Centreon-Central openvpn]#

[/oconf]

Any thoughts?

Did you read the error message ?

File: /etC/openvpn/server.conf
Line: 305
Option: □kd□kd□kd□kd□kd□kd□kd□kd□kd□kd□kd□kd□kd□kd□kd□kd□kd□kd

lol ... I checked the file. When I was editing it in vi apparently I added some text to the end of the file. I corrected those, and then the service failed again. Same error as above.

I had trouble with the easy-rsa part as it is not a part of the openvpn RPM anymore.

Where should the certs be located?
