Low performance if many Virtual Hosts #64 (Next)

[ZerooCool]

I have read this issue : https://github.com/mitchellkrogza/apache-ultimate-bad-bot-blocker/issues/64

My configuration : Apache 2.4 CMS Joomla

I add the ultimate bad bot blocker with my virtualhost : https://wiki.visionduweb.fr/index.php?title=Configurer_le_fichier_.htaccess#Une_liste_de_plus_de_7000_bots_bloqu.C3.A9s_avec_.htaccess

My VirtualHost ( for visionduweb.fr ) : https://wiki.visionduweb.fr/index.php?title=VirtualHosts_des_domaines_enregistr%C3%A9s#visionduweb.fr_.C3.A9coute_du_port_SSL_443

To the bottom from the VirtualHost from visionduweb.fr , i add :

# Inclure la liste noire :
<Location "/">
AuthMerging and
Include /etc/apache2/custom.d/globalblacklist.conf
</Location>

</VirtualHost>

In /etc/apache2/custom.d/globalblacklist.conf i have add all from https://github.com/mitchellkrogza/apache-ultimate-bad-bot-blocker/blob/master/_htaccess_versions/htaccess-mod_rewrite.txt and remove the code for apache 2.2

I restart apache2.

I make a test, if the bad bots are bloqued : curl -A "IRLbot" -I https://www.visionduweb.fr/robots.txt

HTTP/1.1 302 Found
...
Location: https://www.visionduweb.fr/403-forbidden.php

My website work with the domain name : visionduweb.fr But, if i want use visionduweb.fr/forum ..... visionduweb.fr/blog ...... visionduweb.fr/annuaire .... don't work now.

->

Not Found

The requested URL /blog was not found on this server.

If i comment this code my website work good, but then, i don't have ultimate bad bot blocker.

<Location "/">
AuthMerging And
Include /etc/apache2/custom.d/globalblacklist.conf
</Location>

I integrate the list directly into the VirtualHost, without going through a secondary file: By cons, it is not at all practical for maintenance, and it really adds a lot of lines to the configuration.

I really wish I could integrate an external file.

<IfModule mod_rewrite.c>
RewriteEngine on
...

# Bloquer les Bad Bots
RewriteCond %{HTTP_USER_AGENT} \b360Spider\b [NC,OR]
RewriteCond %{HTTP_USER_AGENT} \b404checker\b [NC,OR]
...
RewriteCond %{HTTP_USER_AGENT} \b404enemy\b [NC,OR]
RewriteCond %{HTTP_REFERER} ^http(s)?://(www.)?.*zzlgxh\.com.*$ [NC]
RewriteRule ^(.*)$ - [F,L]
</IfModule>

Why are you modifying globalblacklist.conf ? Have you read the comments in that file saying don't edit anything ? Adding rewrite rules into the globalblacklist WILL break things please follow all instructions. Just use the blocker don't try and modify it.

Maybe @ZerooCool we have a language barrier because I'm not understanding what it is you are trying to do or change :thinking:

[mitchellkrogza]

why are you not using

    <Directory "/var/www/html">
    Options +Includes
    Options +FollowSymLinks -Indexes
    Include custom.d/globalblacklist.conf
    </Directory>

you are using the mod_rewrite which will always have performance issues, that's not a recommended method it's meant for people who do not have access to the backend of apache? Is that your case?

Okay ! I discovered the README which is really well written : https://github.com/mitchellkrogza/apache-ultimate-bad-bot-blocker/blob/master/Apache_2.4/README.md

I modify my directory :

<Directory /var/www/visionduweb.fr>
# Empêcher le suivi des liens symboliques.
# J'autorise le suivi des liens symboliques :
# Permet l'inclusion de la liste noire anti bad bots blocker.
# Depuis le fichier de configuration complémentaire.
Options +FollowSymLinks
# Protéger l'accès aux répertoires.
Options -Indexes
# Désactiver Inclusions Côté Serveur (Server Side Includes / SSI)
Options -Includes
# Permet la prise en compte du fichier .htaccess
AllowOverride All
# Définir le fichier à appeler par défaut.
DirectoryIndex index.php index.html

## Contrôle d'accès Apache 2.4 :
# Toutes les requêtes sont autorisées.
# Fonctionne depuis que j'ai renseigné DirectoryIndex.
## Est commenté pour prendre en compte le script anti bad bot blocker.
## Require all granted

# Inclure le script de liste noire anti bad bots :
# https://github.com/mitchellkrogza/apache-ultimate-bad-bot-blocker/blob/master/Apache_2.4/README.md
Include custom.d/globalblacklist.conf
</Directory>

After commenting REQUIRE : # Require all granted I allow tracking symbolic links : Options +FollowSymLinks The Server Inclusions is disabled : Options -Includes

It works ! The site is well accessible! The bots are denied and return to page 403.

I am surprised however, although I disabled the inclusion, the file is still taken into consideration. According to my tests, it is the order of follow-up of the symbolic links which took priority? So, if I activate +FollowSymLinks and I disable -Includes, the inclusion will still be and work good : Include custom.d/globalblacklist.conf

ByeBye mod rewrite Hello bad bot blocker.
