Hello all
My server is finally up and running again. Server base is Ubuntu 18.04.
This is a LAMP server (LINUX, Apache, MySql and Perl/PHP/Python). UFW (Uncomplicated FireWall) is set up to handle unwanted communication. As this was not enough, a lot of automated attacks is shown on the log, Fail2Ban is installed and running to block the attacker. So far, so good, strong random passwords also has its value.
