    Hello,

    I did those Tutorials

    http://www.howtoforge.com/how-to-set-up-mysql-database-replication-with-ssl-encryption-on-centos-5.4
    http://www.howtoforge.com/installing-powerdns-with-mysql-backend-and-poweradmin-on-centos-5.2

    I need to protect port 53. I am having an mass-attack.

    > Jun 16 12:05:25 domain pdns[21541]: Not authoritative for 'adobe.com',
    > sending servfail to 93.113.174.225 (recursion was desired)

    I do not allow external recursion.

    Do you know how to configure Fail2ban for port 53?

    Thanks and Best Regards,

    Can you post your /etc/fail2ban/jail.conf and /etc/fail2ban/jail.local files? What's the output of
    Code:
    ls -l /etc/fail2ban/filter.d/
    ?
