问题
I have found the sample configuration files provided with mysql 5.0, but I am not able to save them, when I edit them. I also tried saving using a different file name but I received an error by windows saying that I don't have permission to save file in that location (I am an administrator).
I need to edit the configuration file so I am able to save more data. I really can't figure out how to do it and have been struck on this problem since hours. anyone who can figure out whats going on?

to edit my.cnf file in linux opensuse 11.3
first of all open terminal window in su mode
then go to the directory /etc
then open my.cnf file in any of the text editor(kwrite);
now just insert the following two parameters after the line [mysqld]
wait_timeout=50
interactive_timeout=50
save and exit;
restart mysql;
now u can set your session time out by using the following:
set wait_timeout=5000;<br>
it is persistent

You need to have root permissions on my.cnf file to edit it.
So login using root user and then you will be able to edit my.cnf and then you need to restart MySQL server in order to reflect changes.

I see that the basic information was included in directing someone to edit the my.cnf; however, there is no step by step available for beginners. I have a great article with step by step instructions and graphics that explains how to get the MySQL settings and how to change the my.cnf as root through shell. Hope the article helps.
