so, I checked, /etc/hosts, the hostname for the respective server is correct, the master has the right hostname in it, and so does the slave.
I just don't understand where the MySQL client on the slave gets the wrong hostname from. I never even mentioned it anywhere during the system setup and the ISPConfig setup respectively.
EDIT: Setting it to the root user does it, but this can not be a final solution.
