In meinem Bestreben, übermäßige fehlgeschlagene phpMyAdmin
Anmeldeversuche mit zu blockieren fail2ban
, habe ich ein Skript erstellt, das die fehlgeschlagenen Versuche in einer Datei protokolliert:/var/log/phpmyadmin_auth.log
Benutzerdefiniertes Protokoll
Das Format der /var/log/phpmyadmin_auth.log
Datei lautet:
phpMyadmin login failed with username: root; ip: 192.168.1.50; url: http://somedomain.com/phpmyadmin/index.php
phpMyadmin login failed with username: ; ip: 192.168.1.50; url: http://192.168.1.48/phpmyadmin/index.php
Benutzerdefinierte Filter
[Definition]
# Count all bans in the logfile
failregex = phpMyadmin login failed with username: .*; ip: <HOST>;
phpMyAdmin Gefängnis
[phpmyadmin]
enabled = true
port = http,https
filter = phpmyadmin
action = sendmail-whois[name=HTTP]
logpath = /var/log/phpmyadmin_auth.log
maxretry = 6
Das fail2ban
Protokoll enthält:

Wenn ich ausstelle:
sudo service fail2ban restart
fail2ban
E-Mails, von denen ich sage, dass ssh
sie neu gestartet wurden, aber ich erhalte keine solche E-Mail über mein phpmyadmin
Gefängnis. Wiederholte fehlgeschlagene Anmeldungen bei führen phpMyAdmin
nicht zum Senden einer E-Mail.
Habe ich ein kritisches Setup verpasst? Ist der reguläre Ausdruck meines Filters falsch?
Update: Änderungen gegenüber der Standardinstallation hinzugefügt
Beginnend mit einer sauberen fail2ban
Installation:
cp /etc/fail2ban/jail.conf /etc/fail2ban/jail.local
Ändern Sie die E-Mail-Adresse in meine eigene, Aktion in:
action = %(action_mwl)s
Fügen Sie Folgendes hinzu: jail.local
[phpmyadmin]
enabled = true
port = http,https
filter = phpmyadmin
action = sendmail-whois[name=HTTP]
logpath = /var/log/phpmyadmin_auth.log
maxretry = 4
Fügen Sie Folgendes hinzu: /etc/fail2ban/filter.d/phpmyadmin.conf

# Option: failregex
# Notes.: regex to match the password failures messages in the logfile. The
# host must be matched by a group named "host". The tag "<HOST>" can
# be used for standard IP/hostname matching and is only an alias for
# (?:::f{4,6}:)?(?P<host>\S+)
# Values: TEXT
#
# Count all bans in the logfile
failregex = phpMyadmin login failed with username: .*; ip: <HOST>;
# Option: ignoreregex
# Notes.: regex to ignore. If this regex matches, the line is ignored.
# Values: TEXT
#
# Ignore our own bans, to keep our counts exact.
# In your config, name your jail 'fail2ban', or change this line!

Neu starten fail2ban
sudo service fail2ban restart
