My university has a special wireless network that requires you to use a VPN to get into the internet. So I have little script that connects me to the VPN once I get into the wireless:
if [[ "$1" != "wlan0" ]] then return fi # Kill vpnc if it is still active if pgrep vpnc then vpnc-disconnect fi # Exit if we are not connected to bonnet if ! iwconfig wlan0 | grep bonnet then return 0 fi # Handle the action if [[ "$2" == up ]] then vpnc "$vpn_config_file" else vpnc-disconnect fi
This works like a charm and connects and disconnects the VPN with the wifi. The problem is that vpnc has a tendency to die on me. Is there some way to respawn the vpnc if it dies? There is a nice wiki about process management, but it seems that I cannot really use inittab for my purpose here, or at least not straight forward.
What would be a non hack way to respawn vpnc if it dies while I am connected to the certain wireless?
