Sniff mysql instances on the network

sexyrexy asked
Last Modified: 2008-03-03
I am writing a setup wizard for an application that requires a database... right now it supports MSSQL 2000/2005 and MySQL 4 and 5. One of the requirements of the wizard is that it detect any servers running on the network (provided they are on a standard port and open to connections of course).

I can do this with MSSQL by broadcasting a UDP packet on 1434 and all servers will respond with basic info like name and version, but I have no idea how to do something similar with MySQL. So... how is it done?

If you are sniffing port 3306 you may be able to try to logon with a blank username and password - and record the error message, if mysql is in it then there is a mysql server on that connection

a C++ implementation of this is located at



That is impractical for this situation. I need something that will just *broadcast* to the network and wait for replies, not send a logon attempt to every address on the network.
