It looks like you machine can't resolve the URLs.
Can you access other websites by name? Try e.g.
Code:
ping www.google.com
try the following commands and post the output:
Code:
nslookup centos.arcticnetwork.ca
Code:
dig centos.arcticnetwork.ca

Try
Code:
wget "http://mirrorlist.centos.org/?release=5&arch=i386&repo=extras"
Make sure you use the double high quotes (" ").
Then do a
Code:
cat "index.html?release=5&arch=i386&repo=extras"
This should give you
Code:
http://centos.mirror.linuxwerk.com/5.9/extras/i386/
http://mirror.ms5.eu/centos.org/5.9/extras/i386/
http://mirror2.hs-esslingen.de/centos/5.9/extras/i386/

In your /etc/yum.repos.d/Centos-Base.repo you should have the section
Code:
#additional packages that may be useful
[extras]
name=CentOS-$releasever - Extras
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras
#baseurl=http://mirror.centos.org/centos/$releasever/extras/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5
Try uncommenting the baseurl line and try again.

Edit:
Just spotted
Code:
[root@terauser ~]# ping www.yahoo.com
ping: unknown host www.yahoo.com
in your answer.
Why does this fail? Have you tried
Code:
nslookup www.yahoo.com
and what was the output?

Edit2:
What the DNS setup of your machine?
Code:
cat /etc/resolv.conf

Thumbs up

There is dns issue.

1 .Please try adding below dns server to check(later on you can remove it)

Code:
vi /etc/resolv.conf
nameserver 8.8.8.8
2. After this check if you can ping :

Code:
ping yahoo.com
3.Also see iptables are off :

Code:
iptables -L

iptables -F

iptables -L
