Updating fail2ban filters for WordPress

18^th April 2024

Not so long ago, WordPress warned me that some of its Fail2ban filters were obsolete because I have the corresponding WP-fail2ban plugin installed, and the software is present on the underlying Ubuntu Server system. The solution was to connect to the server by SSH and execute the following commands.

wget https://plugins.svn.wordpress.org/wp-fail2ban/trunk/filters.d/wordpress-hard.conf wget https://plugins.svn.wordpress.org/wp-fail2ban/trunk/filters.d/wordpress-soft.conf wget https://plugins.svn.wordpress.org/wp-fail2ban/trunk/filters.d/wordpress-extra.conf sudo mv wordpress-*.conf /etc/fail2ban/filter.d/

The first three commands download the updated configuration files before the last moves them to their final location. It is tempting to download the files directly to that final location, only for wget to create new files instead of overwriting the old ones as required.
