Infrastructure Software

Hi I'm Can Masagi form Indonesia.

I try to install Oracle Enterprise Linux 5 update 2 on HP DL385 G7 at my office. installation is successful and then I try to install public yum repo from page http://public-yum.oracle.com/

I try to execute a command from that page such as:

wget http://public-yum.oracle.com/public-yum-el5.repo

and the terminal displaying:
"--2010-09-06 11:41:42-- http://public-yum.oracle.com/public-yum-el5.repo
Resolving public-yum.oracle.com... failed: Temporary failure in name resolution.
wget: unable to resolve host address `public-yum.oracle.com'"

Later i try to write te repo manually via Gedit on my machine.... Then I try the command yum list as the page said, but the result is like this:

"
Loaded plugins: security
http://public-yum.oracle.com/repo/EnterpriseLinux/EL5/5/base/x86_64/repodata/repomd.xml: [Errno 4] IOError: <urlopen error (-3, 'Temporary failure in name resolution')>
Trying other mirror.
Error: Cannot retrieve repository metadata (repomd.xml) for repository: el5_u5_base. Please verify its path and try again

"

Frankly speaking I'm so confused...., since I try to ping the public-yum.oracle.com domain the result is like this:
"
[root@localhost yum.repos.d]# ping public-yum.oracle.com
ping: unknown host public-yum.oracle.com

"

Why could this happen? and Ho can I solve this problem to run OLE 5 u 5 for my organization?

Thankyou very much...
