how to setup pptp vpn server on archlinux?

Question

I followed the instruction on https://wiki.archlinux.org/index.php/PPTP_Server to setup the pptp vpn server with pptpd.

After everything is done, I cannot connect to the server. I found that there is not any ppp virtual adapter in ifconfig's output. But there is no error in log of pptpd service, and pptpd process is running.

The log of client is below:

Could anyone tell me what's wrong with it? THX!

Answer 1

I found a typo in /etc/ppp/option.pptpd. After correcting it, the server worked.
