MySQL Port Assignments

[Tyler Gingrich]

The main connection to mysql comes in by default on port 3306. What ports
does mysql use for the response?

I assume this is a port range, if so, is it configurable?

If configurable, where?

Thanks

Whatever it needs to in order to communicate with the client. If the
client picks a source port of 9324, the server will use that as the
destination port of the response packets.

It's really no different than apache, telnet, ssh, or most other TCP
based servers.

Can it be modified to use a restricted range? I suspect so if you're
willing to restrict the set of clients that communicate with the
server, too.

But I don't know why you'd want to do that. If you're looking at
firewalling or security, any decent firewall can filter on both source
and destination ports.

But you may have some other reason in mind...
