[webmin-l] Host blocked by MySQL daemon on TCP monitor checks

[Joaquim H. <jo...@we...>]

Something for the FAQ perhaps:

I wanted to see if two of our MySQL-servers were alive, so I added a quick 'n' dirty monitor (TCP, port 3306). Everything was grand until I installed a PHP application on the same server as Webmin (290). After that, I started getting "host blocked .. " errors in the PHP application logs. It took a while to figure it out, but when I did, I deactivated the TCP/3306 monitors and configured Webmin on the two MySQL servers instead, to be aware of binaries, paths, etc. Then I added a proper MySQL monitor on the "master" machine, and the problem never surfaced agin.

I don't know what data is sent when doing a "port ping", if it's just a socket, but MySQL thought Webmin was trying to do "something" anyway, and didn't like the number of attempts without success.
