Unable to connect to Internet

Hi,I installed CentOS 6 and now I am unable to connect to Internet. ifcfg-eth0 looks like this:DEVICE="eth0"BOOTPROTO="static"IPADDR=19... [by naidu]

I have a centos 6.3 server with kvm installed.

I have been following this method described here:

http://linuxwave.blogspot.com/2010/01/setting-virtual-ip-in-centos.html

To assign a virtual IP to one NIC.

I've just installed Centos 6.3 and I'm having trouble with my eth0 connection.

After I installed Centos 6.3 there was no eth0 file, so I made one.

inside my eth0 file I have:

DEVICE=eth0 IPADDR=xxx.xxx.x.xxx NETMASK=xxx.xxx.xxx.x ONBOOT=yes BOOTPROTO=static HWADDR=xx..... NM_CONTROLLED=no

When I run the cmd

# service network start

it brings up the loopback interface and the eth0 interface

I have used the CD to install 11.3 32bit version KDE. I can't boot from dvd. Previously I had 11.2 KDE installed. Since installation I have been unable to connect to the internet with Firefox or log in to the update servers. I have a single PC - AMD Athlon 1GHz hard wired to a Dlink 302G DSL modem. I run a Static setup.

I was messing around with KVM in CentOS 6.3 when I noticed I was having problems with the IP address of my principle network connection (eth0). I backed out my bridge and restored the network-script file for eth0 but the IP address still goes missing after reboot. At this point I have to return to the console and restart the "network" service.

I tried to add a second LAN addresses in CentOS 6.3 on a brand new install and it's not working. I installed a new copy of CentOS 5.7 and tried the same and it worked right away.

Now I'm just trying to setup the alias on the same subnet and it's not working.

Hi guys!I installed Arch on three systems now, on two of them it's running like a charm. But on the third, a desktop pc, I have a strange networking issue. Sometimes after booting I have no internet connection at all, cannot ping and "ip addr" only shows lo and no eth0/1.

The instructions for setting up a LAN, which I assume would allow me to create a sub-domain on my VPS, are the following using the command-line on CentOS:

Using sudo, create the configuration file /etc/sysconfig/network-scripts/ifcfg-eth0:0 with the following:

DEVICE=eth0:0 BOOTPROTO=none ONPARENT=yes TYPE=Ethernet IPADDR=$ADDITIONAL_IP$ NETMASK=255.255.255.0 GATEWAY=XXX.XXX.XXX.1 NAME=eth0:
