UNOFFICIAL GUIDE: Squid external Raspberry PI WPAD lighttpd server Guide with Raspberry Zero LCD HAT code.

[JonathanLee]

Also you can connect a LCD HAT to this from wave share and program it to show who is logged in.

I have the code adapted to output w in a loop so I can see users logged in to the wpad pretty cool

[JonathanLee]

Continued additional security for your WPAD:

I have added an LCD hat to the Zero Pi that uses an adapted vendor provided example python code file. This is so that the screen will also show if any users are logged into the WPAD server. Again, this is very simple to get you into programing a display, it is simple we are adding a string for users logged in to display and adding a service.

Here is a how to guide for this also now that your WPAD is configured and running let us add the LCD hat.

Supplies:
Zero LCD HAT (A)

https://www.amazon.com/LCD-HAT-Secondary-Compatible-Zero/dp/B0DKF8L7VF

You will have to add the GPIO standoff as it is not included in the Zero 2 W you have to manually add the GPIO header so the LCD hat can be plugged in first.

Ok so you got it connected follow the guide for configuration of this.
https://www.waveshare.com/wiki/Zero_LCD_HAT_(A)
I have included the code here also with my adapted steps.

#Enable SPI
sudo raspi-config nonint do_spi 0
#Install Python3 
sudo apt-get update
sudo apt-get install python3-pip
sudo apt-get install python3-pil
sudo apt-get install python3-numpy
sudo apt install python3-luma.oled
sudo apt install python3-luma.lcd
sudo apt install python3-RPi.GPIO
sudo apt install python3-spidev
#Get the Demo Files
sudo apt-get install unzip -y
sudo wget https://files.waveshare.com/wiki/Zero-LCD-HAT-A/Zero_LCD_HAT_A_Demo.zip
sudo unzip ./Zero_LCD_HAT_A_Demo.zip
cd Zero_LCD_HAT_A_Demo

you need to add "dtoverlay=spi1-1cs" to the config.txt file for opening the SPI device.

sudo nano /boot/firmware/config.txt


#adapt the demo file 
sudo cp CPU.py CPU2.py
sudo nano CPU2.py

Adapt the CPU2.py file to activate the middle screen and add the users section.

This is a simple addition do not reinvent the program just activate the new screen with the code given add the string for the output of "w" so that you can always see the current users logged in.

save your adapted CPU2.py example file.

Test with

sudo python CPU2.py

It should run on and run, if not check connections.

Now that it is working, we need to create a service so that it will run every time you reboot or turn on your Raspberry pi.
You might have to add sudo chmod to the .py file to add +x to it to make it executable.

#Navigate to:
cd /lib/systemd/system/
#create a new service
sudo nano display.service
#add the following into the service file. Make sure your working directory is where the python code is.

#save this ctl x

#Run the following 
sudo systemctl daemon-reload
sudo systemctl enable display.service
sudo systemctl start display.service
#check for errors

#It should display this if it works:

#Once it says enabled run

#the dispaly should always run now.

That is it you should now know who is logged into the WPAD at all times, if your not in a SSH session into it the screen show should no users. Meaning that it will only change when someone is on a terminal session of your pi. The screen file is very basic but it can help push you to customize it yourself.

[JonathanLee]

Keep in mind you will have to install an SSL certificate on the Raspberry PI to download the GIT hub file and program. You have to copy the SSL file over to the pi by way of a USB drive and reconfigure your ca certificates for that, or just connect the pi to a non-proxied system to get your files after set it back. If you are like me you just add the certificate so you can access the proxy.

To add the firewalls certificate used with the proxy first download it directly from the firewall so you know it is yours.
after

sudo mkdir /media/usb
sudo mount /dev/sda2 /media/usb -o umask=000
cd /media/usb 
#find your file from the flash drive lets call it CA-Cert.crt
#copy it to the locations is it needed at
sudo cp CA-Cert.crt /etc/ssl/certs
sudo cp CA-Cert.crt /usr/share/ca-certificates/
sudo cp CA-Cert.crt /usr/local/share/ca-certificates/
sudo update-ca-certificates

This should fix your certificate issue to use wget while in the proxy.

Final step we need to make sure that once inside the proxy that you can't call the wpad, meaning that the WPAD is a one-way ticket that the proxy or it's cache cannot access it for added security.

Add this to custom options on the Squid configuration, it is not really needed I add this for fear of container issues,

acl wpad urlpath_regex ^/wpad.dat$
acl wpad urlpath_regex ^/proxy.pac$
acl wpad urlpath_regex ^/wpad.da$
#deny_info 200:/etc/squid/wpad.dat wpad # this is if you manage wpad from squid not needed here
reply_header_access Content-Type deny wpad

[JonathanLee]

Keep in mind that you also might want to disable bluetooth services as they are not needed, and or disable the bluetooth stack so that if a bluetooth usb is plugged into the port it won't work also.

[JonathanLee]

Update: Set your SSH on the wpad to only allow access during business hours. This can be done with the PAM

edit the following file

/etc/security/time.conf

add:

sshd;*;*;AL0500-2300

Meaning I can only access ssh into my wpad durring 5-2300

After adapt /etc/ssh/sshd_config

make sure your listenaddress is the ip of the wpad set your AllowUsers to your login

Example

Port 8085 #change port if needed
AddressFamily inet #ipv4 only
ListenAddress 192.168.1.6 #address of wpad
AllowUsers Jonathan@192.168.1.* # any device that is 192.168.1.X

Change

PermitRootLogin no #no ssh login for root
UsePam yes # turn on pam for use with time restrictions

after adapt
/etc/passwd

for added security also change your login to use the shell rbash and lock down the wad.

Also if you use ipv6 and ipv4 you will have a race condition and sshd will not start on reboots you must also adapt

sudo -i
systemctl edit --full sshd.service

under [unit] add

Requires=network-only.target
After=network-only.taget

This will only start sshd once the network target is running in my example 192.168.1.6 I also have ipv6 running so it would cause issues unless I changed this. If you do not use ipv4 forget about this.

ok here is the updated code man I got to tell you ChatGPT helped me with 90% of this. I am amazed.
