Dear Matthew,
I have configured my proxy settings as mentioned in the webpage. After configuring I just tried to yum list updates. But I am facing the same problem.

[root@fslvm6 fsl]# yum list updates

Please provide a solution.

Thanks in advance

Hello,
          This is not specifically an FSL question, however

http://www.geeksecrets.net/configuring-proxy-settings-on-centos-via-the-command-line/

has some information on how to configure a proxy in centos, and how to configure yum to use the proxy.

Kind Regards
Matthew
