[CentOS] Could not retrieve mirror list while using yum command

Hi

I wanted to download and install the net-snmp package. Usually on my other CentOS boxes i use the following command to do it:

yum install net-snmp

I was able to successfully install net-snmp on 4 of my CentOS boxes but not on one of them. It reports me the following error message:

[root@localhost yum.repos.d]# yum install net-snmp Loaded plugins: fastestmirror Determining fastest mirrors Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=5&arch=i386&repo=os error was [Errno 4] IOError: <urlopen error (110, 'Connection timed out')> Error: Cannot find a valid baseurl for repo: base

Other output that can be some use is :

[root@localhost yum.repos.d]# ls CentOS-Base.repo CentOS-Media.repo

Can someone please let me know what the issue is ? and how to get it working ?

Thanks Jatin
