I'm trying to install OpenVPN on a Centos VPS purchased from budgetvm.com. After I've seemingly successfully installed everything, I'm having the following issues:
When trying to issue the
service openvpn start
command I am greeted with this error:
Starting openvpn: [FAILED]
I check /var/log/messages, and this is the relevant part:

I ran the ls -l command in /dev/net/, this is the output:

When I try to use the cat command on the tun file, I get the same error:
