Unhappy Yum not working after re-install.


I accidently removed yum from my RHEL5 system and then reinstalled it following instructions from a website.

The install was successful but yum is not working.

When i type in

yum check-update

it returns

[root@localhost ~]# yum check-update
Gathering header information file(s) from server(s)
Server: Red Hat Linux 5Client - i386 - Base
retrygrab() failed for:
http://mirror.dulug.duke.edu/pub/yum...rs/header.info
Executing failover method
failover: out of servers to try
Error getting file http://mirror.dulug.duke.edu/pub/yum...rs/header.info
[Errno 4] IOError: <urlopen error >


I am a newbie and dont know, what to do now?

can you dig mirror.dulug.duke.edu ?
if not then there is a DNS issue and you need to check your /etc/resovl.conf

basic information can be used to catch a man in the middle DNS


can you manually go to http://mirror.dulug.duke.edu
