[Openvpn-users] Client vs. Server compatability

Hi all,

Before I further troubleshoot my problem, will a client running OpenVPN
2.0.9 have any issues establishing a tunnel with a server who's running
2.0.6?

I'm not seeing the client logs at all generating on the server, so the
issue might be local to the client. I have it configured verbatim to
other clients.  /var/log/messages looks like the following:

May  3 14:17:07 foo openvpn[7271]: TCP/UDP: Closing socket
May  3 14:17:07 foo openvpn[7271]: SIGTERM[hard,init_instance] received,
