File Permissions and and Log Warnings

[Wasca]

Hi Guys

Getting the following warnings in my OpenVPN log and just want to check what the permission of these files should be for proper security and functionality. Also do the files have correct owner and group assigned to them, I noticed some are root wheel and others are nobody nobody.

Here is the Log Warning…

openvpn[33022]: WARNING: file '/var/etc/openvpn_server0.key' is group or others accessible
openvpn[33022]: WARNING: file '/var/etc/ta.key' is group or others accessible

Here are the file permissions…
