OpenVPN in client mode

OpenVPN 2.1.0

I need to connect to a remote location using OpenVPN. The process starts correctly, and I am getting a connection, but the client then errors out with following sequence:

Sat Nov 12 11:21:42 2011 PUSH: Received control message: 'PUSH_REPLY,route 192.168.1.0 255.255.255.0,route 192.168.10.1,ifconfig 192.168.10.6 192.168.10.5'

Sat Nov 12 11:21:42 2011 Cannot allocate TUN/TAP dev dynamically
Sat Nov 12 11:21:42 2011 Exiting

At the server end connection is showing as open. The server is set up for a TUN device, I need to set up a TUN device on my end. How do I do that?

Thanks for your time.

Re: OpenVPN in client mode

I've not used OpenVPN myself, however a Google search on the error string that beings with "Cannot ioctl..." shows some results that might help. Generally, it looks like a permissions issue.
