I am trying to get PPTP installation up and running on my VPS. I have followed various guides, however, I am unable to connect to the VPN once it’s setup.
I checked my VPS’
/var/log/messages and I found this:
1832 Dec 2 23:38:55 server9987 pptpd: CTRL: Client 22.214.171.124 control connection started 1833 Dec 2 23:38:55 server9987 pptpd: CTRL: Starting call (launching pppd, opening GRE) 1834 Dec 2 23:38:55 server9987 pppd: Plugin /usr/lib/pptpd/pptpd-logwtmp.so loaded. 1835 Dec 2 23:38:55 server9987 pppd: This system lacks kernel support for PPP. This could be because the PPP kernel module could not be loaded, or because PPP was not inc luded in the kernel configuration. If PPP was included as a module, try `/sbin/modprobe -v ppp'. If that fails, check that ppp.o exists in /lib/modules/`uname -r`/net. See README.linux file in the ppp distribution for more details. 1836 Dec 2 23:38:55 server9987 pptpd: GRE: read(fd=6,buffer=8059680,len=8196) from PTY failed: status = -1 error = Input/output error, usually caused by unexpected termina tion of pppd, check option syntax and pppd logs 1837 Dec 2 23:38:55 server9987 pptpd: CTRL: PTY read or GRE write failed (pty,gre)=(6,7) 1838 Dec 2 23:38:55 server9987 pptpd: CTRL: Client 126.96.36.199 control connection finished
It says that my “system lacks kernel support for PPP.” Could this be the cause of the problem, and if so, is there a solution?
You’re almost certainly using an OpenVZ-based VPS. In this case, the host must enable the ppp kernel module (and anything else you might need) for you. Open a support ticket with your hosting provider.
If they are unable or unwilling to make this change for you, buy another VPS, that doesn’t use OpenVZ, so that you can choose your own kernel modules.
