PPTP Debian/Ubuntu OpenVZ Setup Script

I was about to setup another PPTPd on one a new VPS that I got and i have always used a script that used to be @ http://www.putdispenserhere.com/, but the site was down so after a little investigation (google cache) I found a copy that I cleaned up for readability and saved it here for future usage.

Make sure that your VPS has it’s PPP module working. To check, run:

cat /dev/ppp

1	cat /dev/ppp

If you receive this message, your PPP module is ready for use:

cat: /dev/ppp: No such device or address

1	cat: /dev/ppp: No such device or address

To install the script, copy and paste this into your SSH client of choice:

wget http://www.lowendguide.com/pptpinstall.sh
chmod +x pptpinstall.sh
./pptpinstall.sh

wget http://www.lowendguide.com/pptpinstall.sh

chmod +x pptpinstall.sh

./pptpinstall.sh

I used to use that all the time. I was sad when the site went down a lot, I also used the Google Cache as well.

What firewall settings should be used with this?
Specifically, I could not get it to work with apf (http://www.rfxn.com/projects/advanced-policy-firewall/) enabled. With the firewall disabled, things work fine.

Alternately, there’s some hacks to get ufw partly working. What settings are needed for pptp with ufw?

  To allow PPTP in a firewall you have to open port 1723.
  for ufw the command would be something like
  sudo ufw allow 1723
  or
  sudo ufw allow 1723/tcp
  
  Can’t say the apf command, I don’t have that fresh in my mind 🙂

Just wanted to let you know I updated my script slightly along with the documentation.

  Really nice to see you here! I personally used that script on all the vps I use for vpn.
  Easy and quick, good to go solution.
  I’ll have to check out your updates and wee what you made different, except for changing the name 🙂

    The script is now hosted on github, maybe you should link it here. 🙂

      If you read the reply from Bob, he updated the script and site to have better documemtation.
      
      I’ll probably write another post about this after some time.
