How to upgrade fail2ban from 4.x to 5 on WordPress droplet

Asked by mhwebb

Has anyone of you have to deal with the upgrade of the fail2ban plugin on the WordPress droplet from version 4.x to 5? I have a site using the WordPress image from the DO marketplace, and I have never touched the fail2ban plugin other than updating from the WordPress plane when needed. However, the developer has published a warning saying that version 5 is different and one have to update the filters. He’s not being very clear, so I’m not sure what will happen if I click the upgrade button. Anyone of you using the DO droplet with WordPress has already dealt with this situation?

Hello @mhwebb

If you upgrade the plugin you would also need to upgrade the filters as you’ve pointed out. In case you would like to see the default version be 5.0.0

To update the filters you have to download them from the plugins.svn.wordpress.org directory and move them to the filter directory of fail2ban.

$ 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/
