I have been trying to learn about openvpn and trying to learn what is going on from the openvpn log.
My initial trials have thrown up quite a few problems but these may be due to my own lack of knowledge but I did receive some errors which were reported in the log and would appreciate help and advice on either getting updates or correcting the errors. My log is below:-

Future OpenVPN version will ignore --cipher for cipher negotiations. Add 'AES-256-CBC' to --data-ciphers or change --cipher 'AES-256-CBC' to --data-ciphers-fallback 'AES-256-CBC' to silence this warning.

It seems to me there are serious issues with password security and other potential leaks but as I am not a coder I am posting the log and hope somebody has time to help. Please ignore the proprietary stuff which I believe is an artefact of one particular offering. It is the openvpn part that worries me.
