mysqld Privilege Escalation

Hello,

preliminary remark i haven't read all old thread in the mailing list 
archive.
Now i found some problem when i try to use nessus for assessment mysql.

Infact i try to detect my MySQL verision but it say to me that  unknow 
server
in running on that port (3306) this is standard port.
I have installed mysql with a simple rpm and i have a semi standard 
configuration,
semi because i have added a root password.

Am i only that i have receive this error ???

Then i have write a script to find mysqld Privilege Escalation 
Vulnerability, blindlfold

message.
