Because of the missing <b>/etc/ipsec.secrets</b> file, roadwarrior <b>carol</b> and gateway <b>moon</b> each automatically generate a PKCS#1 RSA private key and a self-signed X.509 certificate. Because the UML testing environment does not offer enough entropy, the non-blocking /dev/urandom device is used in place of /dev/random for generating the random primes. <p> The self-signed certificates are then distributed to the peers via scp and are used to set up a road warrior connection initiated by <b>carol</b>
