User 'XXX' could not authenticate every 1 hour.

@kiokoman said in User 'XXX' could not authenticate every 1 hour.:

"reneg-sec 36000"

Thank you for your response.

When I put "reneg-sec 36000" in the custom option for OpenVPN (server), the server cannot start with this error:

Options error: Unrecognized option or missing or extra parameter(s) in /var/etc/openvpn/server2.conf:40: reneg-sec 36000 (2.4.6) ?

Furthermore, I noticed that before the "XXXX could not authenticate", there was an entry in the system log saying:
googleauth.py freeRADIUS: Google Authenticator - Authentication failed. User: XXXXX, Reason: wrong tokencode

It seems that the problem laid in the freeRADIUS as it tried to call the googleauth.py with old OTP every 3600 sec.

@kiokoman It works. Thanks

@kiokoman do you know if I need to export the client again and distribute it to my users after making this change?

[kiokoman]

yes, or you can manually edit every client config

@kiokoman thanks. I assume my users on Windows can just run the installer again and OpenVPN will update?

[kiokoman]

yes, but there is no need actually as i said they just need to modify the configuration

@kiokoman
hi
i'm having the same problem. i didn't quite get it
i see where to config the reneg 0 unser the custom vpn settings, but where to set the 36000?

@pfsenseuser2020 Edit your OpenVPN server and scroll down to the Advanced Configuration section. You add reneg-sec 36000 to the Custom Options field.
