[NamNam]

Hi, i try to remote my mysql database but connection is refused systematicly...

and

sql_mode=ONLY_FULL_GROUP_BY,NO_ZERO_IN_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

and

add this line :

port = 3306

I've restart mysql and server.

I've try to add this :

sudo iptables -I INPUT -p tcp --dport 3306 -m state --state NEW,ESTABLISHED -j ACCEPT
sudo iptables -I OUTPUT -p tcp --sport 3306 -m state --state ESTABLISHED -j ACCEPT

And nothing...
