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
uname -a
