I can change MySQL firewall configuration by terminal??? why??? i change the options by iptables but... the server still blocking the connections... Please people !! i need help
Do you use ufw firewall or bastille? If you use ufw (which is the default for Debain and Ubuntu), then the firewall is managed by the ufw firewall commands on the shell and not with iptables.
