PPTP not working

alexander7567 asked:

I keep getting this error when attempting to log on to my new VPN server..

Sep  6 14:05:19 378465 pptpd[8171]: CTRL: Starting call (launching pppd, opening GRE)
Sep  6 14:05:19 378465 pppd[8172]: Couldn't open the /dev/ppp device: Permission denied
Sep  6 14:05:19 378465 pppd[8172]: Sorry - this system lacks PPP kernel support
Sep  6 14:05:19 378465 pptpd[8171]: GRE: read(fd=6,buffer=8059660,len=8196) from PTY failed: status = -1 error = Input/output error, usually caused by unexpected termination of pppd, check option syntax and pppd logs
Sep  6 14:05:19 378465 pptpd[8171]: CTRL: PTY read or GRE write failed (pty,gre)=(6,7)

Has anybody seen this before? And how did they fix it?

P.S. I am fairly new to MOST linux commands, so please explain well.

Server is CentOS 6

My answer:


You’re using an OpenVZ virtual machine. The hosting provider must specifically enable support for PPP for your virtual machine. Contact your service provider.
