We have learned earlier that easy-rsa is a part of OpenVPN and available on all platforms. Because we have worked through the generation of certificates on Windows, we will now have a look at the same process on a Linux system. On Debian Linux, easy-rsa can be found in the directory /usr/share/doc/openvpn/examples/easy-rsa. Start a root shell and change to this directory:

debian01:/# cd /usr/share/doc/openvpn/examples/easy-rsa
debian01:/usr/share/doc/openvpn/examples/easy-rsa# ls -l
