Share my discovery on GTOP/TTOP voting

This post is originaly part of my journals. Thanks to Krythan's suggestion that I make a seperate thread to discuss it.

My discovory: GTOP and TTOP only check's your ip address. If your device have ipv6 address, they check on your ipv6 address, if no ipv6 then they check on ipv4. Which makes multi-voting on the same device with same network connection (Wi-FI / Ethernet) possible. We just need to find a way to change device's ipv6 address conveniently. You can check your device's ipv6 address here.

Here's my hardcore solution based on changing IPV6 address of my ipad:

Spoiler: my method

Requirements for this method to work:

1. You must be able to change your device's ipv6 address. In my case, my router is OpenWrt system, I checked on my router's control pannel under interface tabs inside the DHCPv6 Client sec, "IPv6-PD: xxxx:xxxx:xxxx:xxxx::/56" confirmed I can allocate ipv6 address to my devices in my local network.
2. You must find a way to be able to change your device's ipv6 address conveniently. In my case, I made sure SLAAC is disabled and DHCPv6 is enabled on my router. Because my router is Linux based system, I could ssh to my router and send command lines to router to change my device's ipv6 address. Here is my python code to do that.
   
   Code:

   import paramiko, random
   
   def generate_ipv6_suffix():
       # Generate a random 8-character hexadecimal string
       hex_suffix = ''.join(random.choice('0123456789abcdef') for _ in range(4))
   
       # Return the uppercase hexadecimal string
       return hex_suffix
   
   
   ssh = paramiko.SSHClient()
   ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
   try:
       ssh.connect('192.168.123.1', username='root')
       while True:
           print('Please press enter to grand a new random ipv6 address:')
           input()
           newipv6 = generate_ipv6_suffix()
           print(newipv6)
           newipv6 = f"'{newipv6}'"
           stdin, stdout, stderr = ssh.exec_command("uci set dhcp.@host[2].hostid=" + newipv6)
           stdin, stdout, stderr = ssh.exec_command('uci commit')
           stdin, stdout, stderr = ssh.exec_command('/sbin/reload_config')
   except KeyboardInterrupt:
       print('KeyboardInterrupt')
   except Exception as e:
       print(e)
   finally:
       ssh.close()

3. Your device must be covenient enough to update the ipv6 address - either disable Wi-Fi and enable it to refresh ipv6 (On mobile devices or computers using Wi-Fi), or disable the net adapter and enable it (On ethernet cable connected device), or maybe unplug the net cable and plug it in (same trick like previous one). I've tried on windows, batch script can disable and enable net adapters with administration. But I don't like the solution since it requires admin, and my pc gets blue screen once while I test my code. My solution is using mobile device (an ipad) over ethernet device (my pc).

As you can see this method I'm using is not suitable for most people. But if you happen to be the small group of people that can try this out, I'm glad to share my solution in detail . Anyway here comes a demo of one attempt vote via my method.

------------------------------------------

Edit: A update for my method.

Spoiler: my method v2.0

I add a script for changing my ipad's ipv6 on my router.

Code:

#!/bin/sh

# Generate a random 4-character string in hex format
random_string=$(cat /dev/urandom | tr -dc '0-9a-f' | head -c 4)

# Set the hostid using uci with the generated random string
uci set dhcp.@host[2].hostid="$random_string"

# Commit changes
uci commit

# Reload the configuration
/sbin/reload_config

Then ceate a shortcut on my ipad to trigger the script via SSH:

Spoiler: SSH shortcut

And then enable the AssistiveTouch by: Seetings->Accessibility->AssistiveTouch

Spoiler: AssistiveTouch

Next, go into "Costomise Top Level Menu", add a icon, modify it to the former ShortCuts I created.

Spoiler: Add a shortcut botton to AssistiveTouch

Finally, go back one layer, change Double-Tap or Long Press (or Single-Tap if you like) to the former Shortcuts I created.

Spoiler: Double-Tap

All settled!
Now you can either click into the "White Spot" to run the shortcut, or though double-tap it.

Here's one of my voting attempt demo.

 

That's what I do before I create my own method. It works fine when mobile data connection is OK. But for me, sometimes the poor data connection just make the whole voting time much longer than it should be, which is annoying.
Sometimes I use mobile data voting. And infinate Loading....ing....ing.....ing.

 

Btw a bonus: if using house wifi, ttop won't pop up human verification at all.

 

For TTOP, most times under Wi-Fi could skip captcha.
For GTOP, never be able to skip.

I guess TTOP's captcha has black/white list? For home ip or relatively "clean" IP provided by some ISP could skip captcha, only ticking the checkbox is fine.

 

Ty so much, now all ign are covered.
