Easy-RSA CRL Regenerator

This script helps to regenerate CRL whenever is expires. Copy it into the Easy-RSA root, e.g. /etc/openvpn/easy-rsa and use it like the all other Easy-RSA scripts:

# source vars
# ./regen-crl

To run it automagically at every day, just put this into /etc/cron.daily:

#!/bin/bash

cd /etc/openvpn/easy-rsa
source vars
./regen-crl

And that's all!
