Info on my Pi-Hole is consolidated on this page.

Links to sites i used for this project

• raspberrypi.org
  • How to install a Raspberry Pi Operating System image on an SD card
  • raspberrypi.org/downloads
• win32diskimager
• pi-hole @ github
• Remote access to the RPi using putty for Windows.
• "Add Wildcard sites to the blacklist" - This also enables TLD blocking ;-)

What i did...

1. Copied 2015-11-21-raspbian-jessie.img to the micro-sd card, using win32diskimager.
2. After first boot, i configured the WiPi USB interface so it would connect to my Wireless network. I did this from the GUI.
3. The i opened a Terminal window on top of the GUI. This might put unnessesary strain on the RPi, but for now it doesn't matter :-)
4. Then i followed Jacob Salmela's guide: "Setting It Up (The Easy Way)"

The DHCP server running on my ISP provided SHOH Router/Wireless Accesspoint cannot be disabled or changed in it's settings, so i will have to manually point my devices to the PiHole DNS server... :-/

If IPv6 is annoying you on the Windows OS disable it correctly !

chronometer.sh for putty

This is my version of the chronometer.sh script. /usr/share/figlet does not contain small font and i would like to rearrange the stuff a tiny bit.

#!/usr/bin/env bash
# Displays Pi-hole stats on the Adafruit PiTFT 2.8" touch screen
# Set the pi user to log in automatically and run this script from /etc/profile

Minibian Pi-hole

Distro is avilable at http://minibianpi.wordpress.com/ and fits on a 1 gigabyte SD card !

My notes

while trying to get this up and running...

1. / have 223Mb free space after install on a 1 gig SD... that is sufficient to install pi-hole but why let parts of the 1 gig SD lay waste unused ?? let's try to expand the partition to fully utilize 1 Gb SD card.
2. Okay - that worked great. 377 Mb is now avilable on the / mountpoint, after this step.
3. Now it's time to apt-get -y update and then apt-get -y upgrade. 59% of space is in use on the / mountpoint, after this step.
4. init 6

Missing packages:

• apt-get -y install curl (After this operation, 1,918 kB of additional disk space will be used.)
• apt-get -y install sudo (After this operation, 2,337 kB of additional disk space will be used.)
• apt-get -y install whiptail (After this operation, 437 kB of additional disk space will be used.)
• apt-get -y install unzip (After this operation, 394 kB of additional disk space will be used.)

Aukay... now i will just try to use the easy pi-hole install curl -L install.pi-hole.net | bash :-P

Disk stats before:

Filesystem      Size  Used Avail Use% Mounted on
/dev/root       864M  481M  327M  60% /

I opted NOT to block IPv6 ads. The install seemed to go without any errors :-D

Disk stats after:

Filesystem      Size  Used Avail Use% Mounted on
/dev/root       864M  593M  215M  74% /

Correction: The install script complains only once due to the fact that the user 'pi' does not exsist.

Conclusion

It is possible to run a pi-hole on Minibian... i might not be the best/safest way to fly a pi-hole - but it works :-P

PiHole + OpenVPN = WIN

I have installed this on the RPi that is running my OpenVPN server. This gives me (and you if you do the same) the option to use the Ablocking DNS server ANYWHERE !!

See Rapsberry Pi OpenVPN Server for more information ;-)
