What I am doing: I have Master - Slave replication in MySQL that is working and just added load balance capabilities using F5. I have configured the F5 according to their site. But when I http://stackoverflow.com/questions/21091850/error-2013-hy000-lost-connection-to-mysql-server-at-reading-authorization-pa am trying to connect to my MySQL server using the IP that the F5 was configured with I get ERROR 2013 (HY000): Lost connection to MySQL server at 'reading authorization packet', system error: 0 Any ideas? Update on my progress : ZERO - i am getting the same error I get no entries in the /var/log/secure as if somebody would try to authenticate coming form the ip where i had created my load balance server. No enties in the mysql error log. The command - returns nothing mysql> SHOW GLOBAL STATUS LIKE 'Aborted_connections'; Empty set (0.00 sec) I've already altered my my.cnf file and add the [mysqld] skip-name-resolve Alterd the connect_timeout to 10. So it seems i get no response for the server i have created on my F5 I finally convinced the F5 admin to pass me the log for the F5 server and i have exctraced all i need form it.

Thanks in advance. 6621 posts ansgar posted 4 years ago Probably too slow connection. Or something in the SSH server which does not work as expected. Well, just guesses here. It's very difficult to debug these tunnel connections. 3 posts stugol posted 4 years ago Thanks anse, probably not too slow as I could putty in manually. Thanks a million, the program rocks but too bad can't tunnel at this time. 6621 posts ansgar posted 4 years ago At least the error message "reading inital communication packet" tells me your tunnel works, as you already touch the mysql server. Well, that does not make it easier to debug :) 18 posts thadin posted 4 years ago I had the same problem. I was

Here is what I have: - I added bind-address in /etc/my-ib.cnf - I can connect to the server from itself using tcpip (--host and --port option) - I can of course connect via pipes - mysqld is up and running -- and it binds correctly on 3306 But I can't connect from other systems. I always get the following error: Code: ERROR 2013 (HY000): Lost connection to MySQL server at 'reading initial communication packet', system error: 0 The setup is: A 64GB server on RHEL 64bits running IB_3.2_GA_5316(ice). A various clients on CentOS or windows XP. I wonder if it's related to this MySQL bug 28359 because it seems it have to do with 64bits ? (though the bug seems to apply to 5.0?) I tcpdumped a few sessions and packets are flowing very fast between client and the server. But unfortunatly always the same error. I raised the connect_timeout value in /etc/my-ib.cnf but it did not made any improvement -- in fact the error is vers fast to appear so it shouldnt be a timeout issue. Thanks for any idea !
