Hi Arun,

1. Is it CentOS 5.2?
2. Also disable CentOS plus repo by doing enable =0 in
/etc/yum.repo/CentOSBase.repo, make sue you don't disable for CentOS & it
is enable
3. Can you please copy above file from working system?
4. Can you now browse through lynx (Linux text browser) ?

Thanks : Regards
