VPN Server on Ubuntu Tutorial - bit-tech.net Forums

RTT · 10th Apr 2007, 10:38

We use Ubuntu here on our internal development servers (apt-get love

) and this morning I needed to setup a VPN server so that I can access some tools that run here from home. I came across a bunch of hurdles and thought i'd document them here for anyone who needs to do the same.

This will allow MS clients and probably Apple too.

Firstly install pptpd

Code:

sudo apt-get install pptpd

Now edit pptpd's config (/etc/pptpd.conf). At the bottom you'll find settings for localip and remoteip. Here's what mine looks like:

Code:

localip 172.198.1.4
remoteip 172.198.2.50-51

localip is the IP of an adapter in the server (yours might be 192.168.0.10 for example)
remoteip: the IPs that clients are allowed to use (i allowed mine to use 172.198.2.50 through 172.198.2.51)

Now we'll set up some users, so edit the chap-config config file(/etc/ppp/chap-secrets). I want to allow two users, so my chap-secrets file looks like this:

Code:

# client        server  secret                  IP addresses
rich             pptpd   apassword                80.40.0.0/13
geoff             pptpd   apassword                212.219.0.0/14

... which allows users rich and geoff, with the passwords 'apassword' to be accepted from those IP subnets. * can be used to allow all IPs. see pppd/chap-secrets man page for more info

You may be good to go at this point. Restart pptpd (sudo /etc/init.d/pptpd restart) and attempt to connect. If it doesn't work, check /var/log/messages for a notice that looks a bit like this:

Code:

Apr 10 09:49:42 beryllium pppd[9619]: Plugin /usr/lib/pptpd/pptpd-logwtmp.so is for pppd version 2.4.3, this is 2.4.4

If you see that, then we need to change pptpd-logwtmp's version number.

This info kindly lifted from CyberAngel at the Ubuntuforums.

We now need a few more things:

Code:

sudo apt-get install libwrap0-dev debhelper
sudo apt-get source pptpd
cd pptpd-1.3.0/plugins
sudo vim patchlevel.h

Change:

Code:

#define VERSION         "2.4.3"

To:

Code:

#define VERSION         "2.4.4"

Save the file and now do:

Code:

cd ../..
sudo apt-get -b source pptpd
sudo dpkg -i pptpd_1.3.0-1ubuntu1_i386.deb
sudo dpkg -i bcrelay_1.3.0-1ubuntu1_i386.deb

Done! Now restart pptpd:

Code:

sudo /etc/init.d/pptpd restart

And you should be good to go!

All you need to do now is add a VPN network connection and connect with the username/password that you set up. Don't forget to hit the IPv4 TCP/IP settings on your client machines for the VPN connection and to untick "Use default gateway on remote network" if you need to (you probably will).

You will also need to change some security settings (image):

VPN Connection > Properties > [Security Tab] -> Advanced

Allow these protocols: (tick) Microsoft CHAP Version2

Hi RTT.
I like your guide on how to make a PPTP network. I followed your guide, and had no problems in setting up everything, however when i connect to my VPN server i get limited connection, and i am not able to access the website on my server if i call its remote address. Could you please help me? I am using Windows Vista by the way.

I've been trying to follow this, but am getting close towards the beginning...

When trying to install the pptpd package, it just sits at "Starting PPTP Daemon: ", and doesn't go beyond that unless I interupt it. Any idea why it's stopping here?

Thanks

msilfver · 27th Jul 2008, 11:41

Make sure the config files has a line feed at the end.
If that doesn't work, try the debug option in pptpd.conf.

I have the exact same problem as this guy was having and i've tried the steps to help that were posted:

but it still hasn't worked is there any other way in which you could think that i can get Small Business Insurance to get passed this step?? Thanks in advance!

HVJoel · 30th Dec 2008, 17:24

Hi,

I've completed the tutorial. I remain with one problem though: the default pptpd port 1723 is already in use. Is there a way to change this port?

Thx in advance

GahocIT · 1st Dec 2009, 01:08

Thank for TUT
And now I have a question
Save the file and now do:

Code:

Quote:

cd ../..
sudo apt-get -b source pptpd
sudo dpkg -i pptpd_1.3.0-1ubuntu1_i386.deb
sudo dpkg -i bcrelay_1.3.0-1ubuntu1_i386.deb

it is error

Could you tell me why error in line ?
Build command 'cd pptpd-1.3.4 && dpkg-buildpackage -b -uc' failed.
E: Child process failed

How will vpn software affect your internet speed? I want to subscribe to the world-secure channel vpn software.They give you the option of taking an account that costs $80 per year and then the speed is 512 kbps.The other option is $120 and then you have unlimited speed.Will the 512 kbps be enough or should i go for the unlimited speed?I live in the UAE and I have a 2mbps speed account.
