How to manually update pure-ftpd server settings so they are preserved on configuration updates

Introduction

Changes to /etc/pure-ftpd.conf get overwritten at some point due to natural configuration changes. There are storage configuration files to hold changes so they are added to the configuration file build when the configuration file is updated.

Procedure

1. Create the local template file:

   touch /var/cpanel/conf/pureftpd/local

   Please note that the local configuration file should be in YAML format

2. Then modify /var/cpanel/conf/pureftpd/local with the desired customizations:

   ---
   MaxClientsPerIP: '18'

3. Pure-FTPD then needs to have the configuration rebuilt:

   /scripts/setupftpserver --force pure-ftpd
