/var/log/secure flooded by error messages from OpenVPN

Resolved
0 votes
Hi,

Just realized that the log is flooded by OpenVPN authentication problem, part of it is attached below.
Each entry was generated when I try to reconnect from a client (I have two, username, username_psp)
Both client are able to connect regardless of the failure message. The phone (username_psp) reconnects much more frequently thus showing up more.

Appreciated if you have any ideas.

    Thanks Nick, it looks like this is inherited from CentOS if I understand it correctly.
    It's not really bothering me and it's beyond my availability to look into it at the moment, so I will just leave it for now.

    Please see this thread. I do something very slightly different and there is a note and a link to it in the thread.
