Could not retrieve mirrorlist...error was 12: Timeout on...
 
Hi,
I'm having this problem, i can't install any package with yum; i used a live CD of Centos 6.3

Following my system specifications:

Code:
[root@asterisk01 ~]# cat /etc/issue
CentOS release 6.3 (Final)
Kernel \r on an \m

[root@asterisk01 ~]# uname -a
Linux asterisk01.calalab.lab 2.6.32-279.el6.x86_64 #1 SMP Fri Jun 22 12:19:21 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
This is the error i'm getting:

Code:
[root@asterisk01 ~]# yum update
Loaded plugins: fastestmirror, refresh-packagekit, security
Loading mirror speeds from cached hostfile
Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os error was

The default repo file for centos base has baseurl commented out, it is the mirrors which should look for the repository and get you the packages. Can I ask you why have you remove the "#" comment from baseurl. Also do you have IPTABLES enabled on your system and Yum is allowed to communicate ?

Hi,

I've commented again the repos like this:

But i'm still having the same issue, iptables service is stopped

More ideas please?

Thanks so much

ok.. is that the same error you got ? if yes lets try some other thing, this time comment out the mirror list and uncomment the baseurl.

yum clean all #do not forget to do this every time you change the repo file.
ping mirror.centos.org #just to check if the server in pinging via your network.
yum update #try running the update

Hi,

After chaging the file like the following:

Code:
# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
#

Then:

Code:
yum clean all
And now the error i have is the following:

Code:

This is driving me crazy!!!

I can't ping mirror.centos.org:

I do have network connection:

Thanks

hmmm.. dont know how to overcome this:

Can you share /etc/resolv.conf file, just to confirm it is checking your primary name server at the first place.

Also try pinging some other domain www.yahoo.com.
