Installing PPTP on CentOS 7 OpenVZ

Although PPTP is not the most secure VPN, it’s easy to setup and use.

Make sure PPTP is enabled on the server

Run the below command

cat /dev/ppp

If you get the below, it means it’s enabled

cat: /dev/ppp: No such device or address

If you don’t see that message, you will have to enable it, usually from SolusVM from your host control panel. Or you can ask your host.
