Hi, thank you for your effort. I installed it on my Wemos D1 Mini and it works very well and fastern then expected.
Unfortunately I've had problems with the script. I'm on macos 10.14.6.
I had to change a bit to make it work.

• I transfered the files to my Arduino Sketchbook
• For me it must be bash instead of sh. Otherwise I got errors. I made a chmod 755 gen_block_lists.sh then ./gen_block_lists.sh. Or other ways work too.
• I had to change the temp dir to something within my home folder. So I took the Ardunio Sketchbook folder. Alter for personal preferences.
• The first for loop didn't work for me either. I had to rewrite it a little bit.

#!/bin/bash
# Script for downloading and converting the ad server lists to smaller files

HOSTS_URL="https://pgl.yoyo.org/adservers/serverlist.php?hostformat=hosts&mimetype=plaintext&useip=0.0.0.0"
#HOSTS_URL="http://someonewhocares.org/hosts/zero/hosts"

#edit: your personal sketchbook folder
PATH_ARDUINO_SKETCHBOOK="/Users/XYZ/Arduino"
#edit if your esphole repo is not located in the sketch folder or was renamed already:
HOSTS_TEMP_DIR=$PATH_ARDUINO_SKETCHBOOK"/esphole-master/utils/temp"

mkdir -p $HOSTS_TEMP_DIR
HOST_LIST="$HOSTS_TEMP_DIR/host_list"

wget $HOSTS_URL -O - | grep -v '#' | grep "0.0.0.0" | sed 's/0\.0\.0\.0 //g' > $HOST_LIST

# saves each domain in a file depending on its characters
for i in $(cat $HOST_LIST)
do
    x=$(echo -n $i | tr '\n' ' ' | tr "\r" " ")
    name=$(echo -n $x | wc -m)
    echo -n ",$x" >> hosts_$(echo -n $name)
done

# adds a kind of EOF for making easier the findUntil
for i in $(ls -1 hosts_*)
do
    echo ",@@@" >> $i
done

mkdir -p $HOSTS_TEMP_DIR/../../data
mv hosts_* $HOSTS_TEMP_DIR/../../data/

I don't use a Unix operating system so I can't do .sh scripts
so I can't process the host file

btw when I changed the wifi name, it just doesn't change. (the wifi name was "esp_24f813")
and when I connect to the wifi it says no internet and nothing happens.

I wonder how the ESPhole gets the IP addresses for the non-blocked DNS. I assume it's been resolved by the DNS IP from the DHCP Server. I want to setup the ESPHole for a whole little side network. That's why I want to leave the clients (mobile, computer, etc) DNS settings untouched, but alter the DNS settings in my DHCP server, pointing to the ESPHole. But then the ESPHole needs it's own DNS fallback IP, not the one from the router. Otherwise it would create an infinite loop. Is it possible to assign a primary DNS IP address on the ESPHole other than that from the router? Thanks a lot!

I love this project! But instead of having over 30,000 domains, is it possible to make wildcard blocking? So that there can few thousand domains and there's going to be faster lookups and resolution. Is it possible?

Hi, i want to add some other hosts ads blacklist for blocked ads and popup in vietnam
How to add that to my esp8266 4mb
My blacklist is 20kb
Very light!

Pls, support me! :)
