I have a centos machine and I was following https://library.linode.com/networking/openvpn/centos-5 this guide. The problem I have is I can't add multiple clients.
When I try to add multiple clients it says:
[root@server]# ./build-key newclient1
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.
What am I doing wrong? How can I add another client to the VPN?
