I have an VPN that I'd like to be on all time. The VPN is an OpenVPN type and was set up and used via the VPN software Tunnelblick. For some unknown reason, the VPN connection or the Tunnelblick process tend to run into a bad state after the VPN has been on for long time, say a day. I'd like to set up a cron job, so it is restarted every night. How to do this?
