Description:
Connections to a MySQL-Server without username via proxy give critical error:

2010-10-04 10:09:09: (critical) proxy-plugin.c.1723: (disconnect_client) [string "/root/reporter.lua"]:45: attempt to index field 'process' (a nil value)

with reporter.lua (can easily be corrected within reporter.lua by an additional
if, eg. if proxy.global.process then ....)

However, if done so, this happens: 

2010-10-05 08:51:19: (critical) network-socket-lua.c:81: sock->challenge: (nil), sock->response: (nil) (looking for username)

<host> is the mysql-proxy, which is listening on port 3306 and is connected to a backend with MySQL 5.1.36 (OpenSuse 11.2)

It is a minor hassle, but I think this case should be handled properly within mysql-proxy.

regards,

Thies

How to repeat:
It happens e.g. when connecting like this

telnet <host> 3306
Trying <host>...
Connected to <host>.
Escape character is '^]'.
8
5.1.36-log),Q7^Sd~l���"bH#s=sMf;0"^]
telnet> quit
Connection closed.

Thank you for the report.

I can not repeat described behavior. Please send us options you start proxy with.
