Hi, ispconfig 3.1.12, debian - multi server setup. 1.web and control panel server. 1. mail server. 1. db server. 2. dns servers. ns1 and ns2. problem. 1. this shows in the mail server mail.log <code>/etc/cron.daily/logrotate: ^Gmysqladmin: connect to server at 'localhost' failed error: 'Access denied for user 'root'@'localhost' (using password: NO)' error: error running shared postrotate script for '/var/log/mysql/mysql.log /var/log/mysql/mysql-slow.log /var/log/mysql/mariadb-slow.log /var/log/mysql/error.log ' run-parts: /etc/cron.daily/logrotate exited with return code 1</code> Question As far as i see the communication between servers is not encrypted. control panel server mysql updates all other servers in chain, this uses port 3306. i would like to encrypt it, how do i achieve this?
