MySQL only listens on one port (3306).
After getting a connection to port 3306, mySQL then opens another for
data tranmission (all those ESTABLISHED entries in netstat).

If you block 3306, no one can connect to your mySQL server.

Subject: Re: Keeping MySQL from listening to ports to connections


Sorry, this post is not information, but I need to echo this
question.  We've got a firewall, but even if we wanted to
open it up we can't because MySQL opens a whole slew of
listening ports: why???  Why doesn't it just open one,
well-defined port to listen on, i.e. 3306 or something?
It makes it difficult to determine what exactly is happening
with the ports on our server when there's 20 listeners all
due to MySQL...

Thanks, and sorry for the redundancy.  I just noticed the
problem today and I haven't had time to investigate the
scope of this behaviour.
