In order to activate PPP (PPPD) on your OpenVZ VPS log into Hypanel, go to Machine Settings and click on Enable PPP.
This will restart your vps and enable PPP (it will take 20-60 seconds). After the vps is restarted you can check if PPPD is active on your vps by running /usr/sbin/pppd
If you get gibberish in the standard output like below then it works.
~�}#�!}!}!} }4}"}&} } } } }%}&)Q�}4}'}"}(}"p})
In case you receive something like command not found you need to install ppp.i386 on your vps (yum install -y ppp.i386 if you are on Centos or apt-get install ppp.i386 if you are on Debian/Ubuntu).
PPP is usually used to run software like PPTP.
