Varnish won't install

Hello.
I have installed cwp on a dedicated server, centos 6.6, no problems there.
The problem happened when i tried to install varnish. It says the command was sent but there is not output. Just an empty gray rectangle where the output should have gone....

Anyone had something similar? How to fix this? I had tried cwp on a vps and i managed to install varnish just fine...

Also i have found that i cannot access internet. When i try to ping google.com it gives unknown host error

Edit: i tried to install cwp on a spare vps with no problems. I can ping websites and install varnish. The only difference is it is a vps and the one i am having problems is a dedi.

Before installing cwp on the dedi i can ping to other sites, but after the installation that is no longer possible, something gets messed on the installation that damages the connectivity of the server to the outside...

have you checked you /etc/resolv.conf configuration ?
Your nameserver resolvers for server are listed there.

mostly we are using google dns
nameserver 8.8.8.8

it shows this
# Generated by NetworkManager
search net
nameserver 127.0.0.1

will try to add google nameserver

then that is your issue.

execute the following command

Code: [Select]

echo "nameserver 8.8.8.8" > /etc/resolv.conf

i have the problem too,and the dns is right:
[root@globetour-server ~]# vi /etc/resolv.conf
nameserver 8.8.8.8
nameserver 8.8.4.4
