Description

This client refuses to do NCP...

Nov  7 11:35:34 fbsd93 openvpn[93232]: OpenVPN 2.4_alpha2 amd64-portbld-freebsd9.3 [SSL (OpenSSL)] [LZO] [LZ4] [MH/RECVDA] [IPv6] built on Nov  6 2016
Nov  7 11:35:34 fbsd93 openvpn[93232]: library versions: OpenSSL 0.9.8zh-freebsd 3 Dec 2015, LZO 2.09

and unless one *knows* that this openssl version is old enough to not have the needed bits for AEAD, it's a bit tricky to debug why it ends up with

Nov  7 11:35:36 fbsd93 openvpn[93233]: WARNING: INSECURE cipher with block size less than 128 bit (64 bit).  This allows attacks like SWEET32.  Mitigate by using a --cipher with a larger block size (e.g. AES-256-CBC).

feature wanted!
