I recently installed your VPN software on my Mac and since I did my log files have been filling up with the following message. There is a new batch of these coming in every minute or so.
com.deterministicnetworks.driver.dne: socket_event_callback: en0 link on
com.deterministicnetworks.driver.dne: dne_event: Proto 0 interface en, event KEV_DL_LINK_OFF
CiscoVPN : attempting to attach to all available ethernet interfaces.
CiscoVPN : checking if we are already attached to interface: vboxnet0
CiscoVPN : checking if we are already attached to interface: en1
CiscoVPN : checking if we are already attached to interface: en0
What can I do to stop these or at lease disable the driver when I'm not using it.
Wild-ass guess here: you're using wifi but you have a wired port. It looks like something is polling the wiredport for carrier, and issuing a linkup/linkdown event which is causing the Cisco VPN client to react by trying to re-attach. Try disabling any ports you are not using and see if the log entries go away.
