wget -q -N https://raw.githubusercontent.com/maravento/blackip/master/checksum.md5
md5sum blackip.txt | awk '{print $1}' && cat checksum.md5 | awk '{print $1}'

Ipset/Iptables Rules

Edit your Iptables bash script and add the following lines (run with root privileges): / Edite su bash script de Iptables y agregue las siguientes líneas (ejecutar con privilegios root):

#!/bin/bash
# https://linux.die.net/man/8/ipset
# variables
ipset=/sbin/ipset
iptables=/sbin/iptables

# Replace with your path to blackip.txt
ips=/path_to_lst/blackip.txt

# ipset rules
$ipset -L blackip >/dev/null 2>&1
if [ $? -ne 0 ]; then
        echo "set blackip does not exist. create set..."
        $ipset -! create blackip hash:net family inet hashsize 1024 maxelem 10000000
    else
        echo "set blackip exist. flush set..."
        $ipset -! flush blackip
fi
$ipset -! save > /tmp/ipset_blackip.txt
# read file and sort (v8.32 or later)
cat $ips | sort -V -u | while read line; do
    # optional: if there are commented lines
    if [ "${line:0:1}" = "#" ]; then
        continue
    fi
    # adding IPv4 addresses to the tmp list
    echo "add blackip $line" >> /tmp/ipset_blackip.txt
done
# adding the tmp list of IPv4 addresses to the blackip set of ipset
$ipset -! restore < /tmp/ipset_blackip.txt

# iptables rules
$iptables -t mangle -I PREROUTING -m set --match-set blackip src,dst -j DROP
$iptables -I INPUT -m set --match-set blackip src,dst -j DROP
$iptables -I FORWARD -m set --match-set blackip src,dst -j DROP
echo "done"

Optional: Ipset/Iptables IPDeny Rules

You can add the following lines to the bash above to include full country IP ranges with IPDeny adding the countries of your choice. / Puede agregar las siguientes líneas al bash anterior para incluir rangos de IPs completos de países con IPDeny agregando los países de su elección.

# Put these lines at the end of the "variables" section
# Replace with your path to zones folder
zones=/path_to_folder/zones
# download zones
if [ ! -d $zones ]; then mkdir -p $zones; fi
wget -q -N http://www.ipdeny.com/ipblocks/data/countries/all-zones.tar.gz
tar -C $zones -zxvf all-zones.tar.gz >/dev/null 2>&1
rm -f all-zones.tar.gz >/dev/null 2>&1

# replace the line:
cat $ips | sort -V -u | while read line; do
# with (e.g: Russia and China):
cat $zones/{cn,ru}.zone $ips | sort -V -u | while read line; do

Important about Ipset/Iptables Rules

Ipset allows mass filtering, at a much higher processing speed than other solutions (check benchmark). / Ipset permite realizar filtrado masivo, a una velocidad de procesamiento muy superior a otras soluciones (consulte benchmark).
Blackip is a list containing millions of IPv4 lines and to be supported by Ipset, we had to arbitrarily increase the parameter maxelem (for more information, check ipset's hashsize and maxelem parameters). / Blackip es una lista que contiene millones de líneas IPv4 y para ser soportada por Ipset, hemos tenido que aumentar arbitrariamente el parámetro maxelem (para más información, consulte ipset's hashsize and maxelem parameters).
Ipset/iptables limitation: "When entries added by the SET target of iptables/ip6tables, then the hash size is fixed and the set won't be duplicated, even if the new entry cannot be added to the set" (for more information, check Man Ipset) / Limitación de Ipset/iptables: "Cuando las entradas agregadas por el objetivo SET de iptables/ip6tables, el tamaño del hash es fijo y el conjunto no se duplicará, incluso si la nueva entrada no se puede agregar al conjunto" (para más información, consulte Man Ipset).
Heavy use of these rules can slow down your PC to the point of crashing. Use them at your own risk. / El uso intensivo de estas reglas puede ralentizar su PC al punto de hacerlo colapsa. Úselas bajo su propio riesgo.
tested on: / probado en: iptables v1.8.7, ipset v7.15, protocol version: 7

Squid Rule

Edit:

/etc/squid/squid.conf

And add the following lines: / Y agregue las siguientes líneas:

# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS
acl blackip dst "/path_to/blackip.txt"
http_access deny blackip

Important about BlackIP

Should not be used blackip.txt in IPSET and in Squid at the same time (double filtrate) / No debe utilizar blackip.txt en IPSET y en Squid al mismo tiempo (doble filtrado)
blackip.txt is a list IPv4. Does not include CIDR / blackip.txt es una lista IPv4. No incluye CIDR
blackip.txt has been tested in Squid v3.5.x and later / blackip.txt ha sido testeada en Squid v3.5.x y posteriores

Optional: Squid-Cache Advanced Rules

blackip contains millions of IP addresses, therefore it is recommended: / blackip contiene millones de direcciones IP, por tanto se recomienda:

Use blackcidr.txt to add IP/CIDR that are not included in blackip.txt (By default it contains some Block CIDR) / Use blackcidr.txt para agregar IP/CIDR que no están incluidas en blackip.txt (Por defecto contiene algunos Block CIDR)
Use allowip.txt (a whitelist of IPv4 IP addresses such as Hotmail, Gmail, Yahoo. etc.) / Use allowip.txt (una lista blanca de direcciones IPs IPv4 tales como Hotmail, Gmail, Yahoo. etc)
Use aipextra.txt to add whitelists of IP/CIDRs that are not included in allowip.txt / Use aipextra.txt para agregar listas blancas de IP/CIDR que no están incluidas en allowip.txt
By default, blackip.txt excludes some private or reserved ranges RFC1918. Use IANA (iana.txt) to exclude them all / Por defecto, blackip.txt excluye algunos rangos privados o reservados RFC1918. Use IANA (iana.txt) para excluirlos todos
By default, blackip.txt excludes some DNS servers included in dns.txt. You can use this list and expand it to deny or allow DNS servers / Por defecto, blackip.txt excluye algunos servidores DNS incluidos en dns.txt. Puede usar esta lista y ampliarla, para denegar o permitir servidores DNS
To increase security, close Squid to any other request to IP addresses / Para incrementar la seguridad, cierre Squid a cualquier otra petición a direcciones IP

### INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS ###

## OPTIONAL LST ##
# Allow IP list
acl allowip dst "/path_to/allowip.txt"
http_access allow allowip
# Allow IP/CIDR list (not included in allowip.txt)
acl aipextra dst "/path_to/aipextra.txt"
http_access allow aipextra
# IANA list (not included in allowip.txt)
acl iana dst "/path_to/iana.txt"
http_access allow iana
# DNS list (excluded from blackip.txt)
acl dnslst dst "/path_to/dns.txt"
http_access allow dnslst # or deny dnlst
# Block IP/CIDR list (not included in blackip.txt)
acl blackcidr dst "/path_to/blackcidr.txt"
http_access deny blackcidr

## BLACKIP LST ##
acl blackip dst "/path_to/blackip.txt"
http_access deny blackip

Or you can replace blackip with a zero trust rule (ZTR) / O puede reemplazar blackip con una regla de confianza cero (ZTR)

## DENY ALL IP ##
acl no_ip url_regex -i [0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}
http_access deny no_ip

UPDATE

⚠️ WARNING: BEFORE YOU CONTINUE

This section is only to explain how update and optimization process works. It is not necessary for user to run it. This process can take time and consume a lot of hardware and bandwidth resources, therefore it is recommended to use test equipment / Esta sección es únicamente para explicar cómo funciona el proceso de actualización y optimización. No es necesario que el usuario la ejecute. Este proceso puede tardar y consumir muchos recursos de hardware y ancho de banda, por tanto se recomienda usar equipos de pruebas

Blackip Update

The update process of blackip.txt is executed in sequence by the script bipupdate.sh. The script will request privileges when required. / El proceso de actualización de blackip.txt es ejecutado en secuencia por el script bipupdate.sh. El script solicitará privilegios cuando lo requiera.

wget -q -N https://raw.githubusercontent.com/maravento/blackip/master/bipupdate/bipupdate.sh && chmod +x bipupdate.sh && ./bipupdate.sh

Dependencies

Update requires python 3x and bash 5x / La actualización requiere python 3x y bash 5x

pkgs='wget git subversion curl idn2 perl tar rar unrar unzip zip python-is-python3 squid ipset'
if ! dpkg -s $pkgs >/dev/null 2>&1; then
  apt -y install $pkgs
fi

Capture Public Blocklists

Capture IPv4 from downloaded public blocklists (see SOURCES) and unifies them in a single file / Captura las IPv4 de las listas de bloqueo públicas descargadas (ver FUENTES) y las unifica en un solo archivo

DNS Loockup

Most of the SOURCES contain millions of invalid and nonexistent IP. Then, a double check of each IP is done (in 2 steps) via DNS and invalid and nonexistent are excluded from Blackip. This process may take. By default it processes in parallel ≈ 6k to 12k x min, depending on the hardware and bandwidth / La mayoría de las FUENTES contienen millones de IP inválidas e inexistentes. Entonces se hace una verificación doble de cada IP (en 2 pasos) vía DNS y los inválidos e inexistentes se excluyen de Blackip. Este proceso puede tardar. Por defecto procesa en paralelo ≈ 6k a 12k x min, en dependencia del hardware y ancho de banda

HIT 8.8.8.8
Host 8.8.8.8.in-addr.arpa domain name pointer dns.google
FAULT 0.0.9.1
Host 1.9.0.0.in-addr.arpa. not found: 3(NXDOMAIN)

Run Squid-Cache with Blackip

Run Squid-Cache with Blackip and any error sends it to SquidError.txt on your desktop / Corre Squid-Cache con Blackip y cualquier error lo envía a SquidError.txt en su escritorio

Check execution (/var/log/syslog)

Blackip: Done 02/02/2024 15:47:14

Important about Blackip Update

tw.txt containing IPs of teamviewer servers. By default they are commented. To block or authorize them, activate them in bipupdate.sh. To update it use tw.sh / tw.txt contiene IPs de servidores teamviewer. Por defecto están comentadas. Para bloquearlas o autorizarlas activelas en bipupdate.sh. Para actualizarla use tw.sh
You must activate the rules in Squid before using bipupdate.sh / Antes de utilizar bipupdate.sh debe activar las reglas en Squid
Some lists have download restrictions, so do not run bipupdate.sh more than once a day / Algunas listas tienen restricciones de descarga, entonces no ejecute bipupdate.sh más de una vez al día
During the execution of bipupdate.sh it will request privileges when needed / Durante la ejecución de bipupdate.sh solicitará privilegios cuando los necesite

AllowIP Update

allowip.txt is already updated and optimized. The update process of allowip.txt is executed in sequence by the script aipupdate.sh / allowip.txt ya esta actualizada y optimizada. El proceso de actualización de allowip.txt es ejecutado en secuencia por el script aipupdate.sh

wget -q -N https://raw.githubusercontent.com/maravento/blackip/master/bipupdate/wlst/aipupdate.sh && chmod +x aipupdate.sh && ./aipupdate.sh

OBJECTION

Due to recent arbitrary changes in computer terminology, it is necessary to clarify the meaning and connotation of the term blacklist, associated with this project: In computing, a blacklist, denylist or blocklist is a basic access control mechanism that allows through all elements (email addresses, users, passwords, URLs, IP addresses, domain names, file hashes, etc.), except those explicitly mentioned. Those items on the list are denied access. The opposite is a whitelist, which means only items on the list are let through whatever gate is being used.

Debido a los recientes cambios arbitrarios en la terminología informática, es necesario aclarar el significado y connotación del término blacklist, asociado a este proyecto: En informática, una lista negra, lista de denegación o lista de bloqueo es un mecanismo básico de control de acceso que permite a través de todos los elementos (direcciones de correo electrónico, usuarios, contraseñas, URL, direcciones IP, nombres de dominio, hashes de archivos, etc.), excepto los mencionados explícitamente. Esos elementos en la lista tienen acceso denegado. Lo opuesto es una lista blanca, lo que significa que solo los elementos de la lista pueden pasar por cualquier puerta que se esté utilizando.

Therefore / Por tanto

blacklist, blocklist, blackweb, blackip, whitelist, etc.

are terms that have nothing to do with racial discrimination / son términos que no tienen ninguna relación con la discriminación racial.
