執行YUM時出現以下錯誤訊息 :
[root@localhost ~]# yum -y install net-snmp
Loaded plugins: fastestmirror
Determining fastest mirrors
Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=5&arch=x86_64&repo=addons error was
[Errno 4] IOError: <urlopen error (-3, 'Temporary failure in name resolution')>
Error: Cannot find a valid baseurl for repo: addons

當出現以上的錯誤後，請先試著Ping mirrorlist.centos.org，發現ping不通，出現 ping: unknown host mirrorlist.centos.org 的訊息。
請先確認DNS的設定上是否有問題
