Im trying to setup IPSEC tunnel with openSpawn between a windows and linux machine. This guide i found told me to do the following once CA and all that has been complete but the last thing for certificates...... If this certificate is needed for a Windows box, you'll need to convert it to a p12 format: $ openssl pkcs12 -export -in winhost.example.com.pem -inkey winhost.example.com.key -certfile demoCA/cacert.pem -out winhost.example.com.p12 This gives me an error saying unable to load private key. This is my source for creating my tunnel: http://natecarlson.com/linux/ipsec-x509.php Any help please.......?????
