Recently i need a linux machine in my office for server . So i installed Fedora 13 and try to install mysql server using yum. But i can't complete it because yum is not connecting to internet. It's because of our proxy server. Before 2 months i installed Fedora 12 and failed to install Mysql using yum. I just searched for setting proxy in yum and got the answer for it. This is the solution, 1. open /etc/yum.conf 2. add proxy=http://proxyaddress:port Voila :D , it works fine for me. Atlast my 3 months quest ends here . :P .
