tombar@Khazad-dum:/etc/openvpn$ sudo vim vars 
tombar@Khazad-dum:/etc/openvpn$ . ./vars 
NOTE: If you run ./clean-all, I will be doing a rm -rf on /etc/openvpn/keys
tombar@Khazad-dum:/etc/openvpn$ sudo ./clean-all 
Please source the vars script first (i.e. "source ./vars")
Make sure you have edited it to reflect your configuration.
tombar@Khazad-dum:/etc/openvpn$ ./build-ca 
  Please edit the vars script to reflect your configuration,
  then source it with "source ./vars".
  Next, to start with a fresh PKI configuration and to delete any
  previous certificates and keys, run "./clean-all".
  Finally, you can run this tool (pkitool) to build certificates/keys.
