This gives me the impression that you had already previously set a root 
password for this server, and are attempting to change it. If this is 
right, then you need to connect to the MySQL server using the hostname 
you originally specified for the root user. E.g. user root needs to 
connect with some other hostname and it can't be an aliased hostname. It 
has to be the hostname that was set for the machine at networking time. 
'T8.linux' is not the hostname. It is just an alias for 
'localhost.localdomain' and it won't be sent to the MySQL server.

So I think you either must set your machine to the hostname MySQL is 
expecting for the root user ('T8.linux'?) or you must reset the MySQL 
root password.

There is a way to reset the root password, documented on the MySQL 
website, or in Paul DuBois' excellent book MySQL (Second Edition). You 
might want to read DuBois' suggestions for setting the root password, 
and at the same time change your host's configuration so that it is 
assigned a consistent hostname.

MySQL is big and complex, and there are a lot of books on the market for 
it. I very highly reccomend you buy and use DuBois' book. I can't live 
without it myself. No one else writes about MySQL better.
