GRE: read from PTY failed error when connecting multiple clients to PPTP

Question

I have just installed a pptp server and now I can make it work. The problem is, it can only be connected to by one client. How do I set it up so that it will allow multiple users?

Here is the error log that is thrown after the second user tries to login..

Aug  5 23:28:14 vps1 pptpd[1570]: GRE: read(fd=6,buffer=611860,len=8196) from PTY failed: status = -1 error = Input/output error, usually caused by unexpected termination of pppd, check option syntax and pppd logs
Aug  5 23:28:14 vps1 pptpd[1570]: CTRL: PTY read or GRE write failed (pty,gre)=(6,7)

It is working for the first user.. but cannot handle two users at once. — reikyoushin, Aug 05 '13 at 21:49
nope.. i've already created a second user but still only one of them would work at a time.. — reikyoushin, Aug 06 '13 at 12:53

I think root of the issue is openvz itself.

The problem is, it can only be connected to by one client.

it seems that on the host system is not loaded module ip_nat_pptp/nf_nat_pptp. You could ask your hoster to do that.

yeah i already figured that out and gave up. will look for a host that offers Xen or KVM instead.. thanks! will give you +1 even if its not the solution. at least for others it would be clear that it is not possible. – reikyoushin Aug 10 '13 at 17:00
