I simply want to open up mysql to be accessible from any server ip.

I have already commented out the bind-address in /etc/mysql/my.conf.

I have already setup the user account within mysql.

I have no clue whats stopping me from connecting.

The more challenging I see this being the more I realize how much of a security risk it is, and I get that, I just want to be able to do it temporarily.

I think that the iptables firewall is the last thing that is preventing me from achieving this, but sudo iptables -A INPUT -p tcp -m tcp --dport 3306 -j ACCEPT is seemingly doing nothing.

thomas@vannevar:~$ netstat -tl

Did you comment out the bind-address or bind it to 0.0.0.0?

Also, try flushing your firewall completely. Dump them with an iptables-save > foo.fw and then execute an iptables -F to empty the rules list.

You can also see if it's bound correctly by doing a netstat -tl to see if mysql is listing to 3306 on "*"

You need to enable it in mysql as well.

For example: USE mysql; SELECT * FROM user; UPDATE user set host ="%" WHERE host='127.0.0.1'; Hope this helps.
