Setup PPTP on Ubuntu 16.04 with WiFi router support

This guide has been tested with Ubuntu 16.04 Server.

This configuration is also supported by WiFi Routers

Setup PPTP Server
First we need to install pptp server using apt-get

Then we need to configure the pptpd.

Add server IP and client IP at the end of the file. You can add like below:

This sets up the PPTP server to use IP 192.168.67.1 while distributing the IP range 192.168.67.100 to 192.168.67.200 to PPTP clients. Change these as you wish as long as they are private IP addresses and do not conflict with IP addresses already used by your server.

Configure DNS servers to use when clients connect to this PPTP server

Uncomment the ms-dns and add google like below or OpenDNS

Now change the following

to

Now add a VPN user in /etc/ppp/chap-secrets file.

The column is username. Second column is server name, you can put “pptpd” in there. Third column is password. The last column is the IP addresses, you can put * to allow all IP.

Finally start your server

Setup IP Forwarding
To enable IPv4 forward. Change /etc/sysctl.conf file, add forward rule below.

Uncomment the line

Then reload the configuration

Add forward rule in iptables

adding to the bottom just before the exit 0

This example is using 192.168.0 for its PPTP subnet. The second rule adjusts the MTU size :

You are done. Just reboot your server and you should be able to connect to using PPTPD and send all your traffic through this server.

How to update speedtest mod – Pi-hole

Add Speedtest to Pihole WebUI

So this project is  just another fun project integrating speedtest to PiHole Web UI.

Note : It’s just a quick solution , nowhere near perfect . If you made it better please let me know here Google+ Community

It will be using speedtest.net on background for testing. More frequent the speed tests more data will used.

What does this mod have in extra ?

  1. Speedtest results of 1 /2 4/ 7/30  days as graph.
  2. Custom speed test server selection.
  3. Detailed speedtest results page.
  4. Ability to schedule speedtest interval.

Start with installing required packages on your Raspberry Pi / Linux

Find php version 

if it is 5.x

if it is 7.x

Restart Pi

You can try run it using

If Everything is ok, proceed to next step

Get the new set of admin Code from github ( New method  or try old one here)

Test its working

Go to your pihole admin page

http://pi.hole/admin

Note : First load may be slow

Login 

Now go to settings and enable speedtest

Note: If the item does not change to option you have chose just go to dashboard and comeback, it will be fine. I am currently working on it

Now create a speedtest Manually and make sure it’s appearing on dashboard

Go back to terminal and type  Not needed  : admin will call this if there is no data 

It may take few seconds to appear , but once its loaded you can see that on dashboard.

Please consider posting a screenshot link in the comments , I would like to know how it looks on different devices.

If there are any problems , ask here :  PiHole mods G+

If you are upgrading pihole please revert all changes back and do the upgrade. Scroll down for instructions .

Speedtest gone missing after Pi-hole update

Dont worry your data is safe , update procedure here

Can the developer held responsible if anything goes wrong.

Absolutely not ,but you can always ask for help

I lost my DB file what Should I do ?

Here is a blank one : SpeedtestDB Zip

Can i get more features added to it ?

You can ask me via this link, I will do if feasible

Can I get it via regular pihole -up

Not currently. Hope this will get integrated into the baseline. If that happens you can easily get it via regular pihole update

The time is not not showing correctly in chart 

Please get latest code via git pull

I don’t want this , I want to go back to the original version .

If you have followed all instructions correctly , the code below will revert all the changes you have done .


Notes

Just a quick solution , you should move the db file to a directory outside www folder for security reasons.

Testing 

Run as a Service

Make sure that you are in virtual environment 

(env) pi@raspberrypi:~ $

else run

source /home/pi/env/bin/activate

 

We need to create an shell script to enable virtual environment “hotword.sh “

nano /home/pi/assistant-sdk-python/google-assistant-sdk/googlesamples/assistant/library/hotword.sh To run as a service you need to create a service file in /lib/systemd/system/ folder

sudo nano /lib/systemd/system/assistant.service Enable and start service

sudo systemctl start assistant.service

Check Status of the service

sudo systemctl status assistant.service

Enable service

sudo systemctl enable assistant.service
