Question

I am getting the following error

ERROR 2013 (HY000): Lost connection to MySQL server at 
\'reading authorization packet\', system error: 0

Answer 1

Another possibility can be connection reset from the TCP wrappers (/etc/hosts.deny and /etc/hosts.allow). Just check what is coming in from the telnet to port 3306 - if it is nothing, then there is something is in the middle preventing communication from happening.
