I'm trying to get a PPTP server running on a ubuntu server, but I've run into some issues with it. I followed this guide on how to set up pptpd on my server, and everything went smooth, but when I try to connect with my mac, it gives me this error:

VPN Error

Here's my configuration:

Does anyone have any idea as to what I'm doing wrong here?

Update: Here's what the pptpd.log has to say about it:

steve@debian:~$ sudo tail /var/log/pptpd.log 
sudo: unable to resolve host debian

My pptpd options are:

OSX had bad implementation of PPTP - try using a windows client, or run virtualbox and run windows to test the VPN. This cost me two weeks of summer till i found out!

that is not to say that PPTP wont work, it's just that different terminators, (ubuntu in your case, hardware VPN, windows server VPN service), even using the same radius backend and no change in client configuration, some work, and some don't. (amazing, to be honest) –  Mister IT Guru Feb 23 '11 at 15:45
    
i've had good luck with OSX10.6 built-in pptp client hitting pptpd on CentOS with little to no effort, what version of OSX are we talking here? –  SpacemanSpiff Sep 26 '11 at 23:51
    
I don't think he knows what he's talking about. OSX's PPTP implementation is fine and on par or better than the Windows version. –  verhogen Mar 24 '12 at 23:50
    
I may have made a mistake here, it's the IPSEC implementation that'a bit shoddy, although I do recall there being problems with pptp and OSX early last year (checking help desk cases - yeahup, 5 cases, but fixed with apple update) - anyway, it's a really old question, SO VOTE ME BACK UP.
