Hello /etc/sysconfig/network-scripts/ifcfg-eth0 looks like this: # Intel Corporation 82545EM Gigabit Ethernet Controller (Copper) TYPE=Ethernet NAME=eth0 NM_CONTROLLED=no IPV4_FAILURE_FATAL=yes UUID=cc2635ff-3c14-48ba-b19a-84c5b9d36a9d ONBOOT=yes DEVICE=eth0 BOOTPROTO=none HWADDR=00:50:56:01:00:01 BROADCAST=192.168.0.255 IPADDR=192.168.0.10 NETMASK=255.255.255.0 NETWORK=192.168.0.0

Dear Centos-Virt: Help!

Hello, in /etc/sysconfig/network-scripts/ifcfg-eth0 I have this <ifcfg-eth0> ... IPV6INIT=yes IPV6ADDR=prefix::5 IPV6ADDR_SECONDARIES="prefix::2 prefix::3 prefix::4" IPV6_AUTOCONF=no IPV6_DEFAULTGW=prefix::1 IPV6_DEFAULTDEV=eth0 </ifcfg-eth0> when I enter ifconfig the IPv6 addresses are in a different order <ifconfig> eth0 Link encap:Ethernet HWaddr ... inet addr:...

I'm having a problem permanently assigning a static IPv6 address to my CentOS v5.5 box. I have IPv6 enabled and the link local address is automatically brought up. I can manually ifconfig the address but when I configure it in ifcfg-eth0 and restart the network init script the IPv6 address is not assigned. Anyone have any ideas on how to fix this?

Hello, I'm running a CentOS 5.6 server through linode. I am atempting to configure it for ipv6, previously this had been done though not by me on a ubuntu box so the hardware can take it. I've got an ipv6 tunnel through Hurricane Electric and at a shell prompt have done the following: ifconfig sit0 up ifconfig sit0 inet6 tunnel ::IPV4 Address ifconfig sit1 up ifconfig sit1 inet6 add IPV6

Hi, Has anyone tried upgrading xen domu's from 5.2 to 5.3? I just did a yum upgrade glibc & yum upgrade yum. All appeared to go well but when I rebooted and tried to connect to the network, I could not. Looking at /etc/sysconfig/network-scripts I see that the that there is now an ifcfg-eth0 and an ifcfg-eth0.bak. ifcfg-eth0 now contains configuration for a dynamically configured

Hi, I have an eth0 interface (it's a CentOS 6 guest VM on a KVM host) which is configured as follows (see below) with a primary public IP address of xxx.xxx.xxx.130 (which works fine). I cannot set an alias IP address. I want eth0 to also use another IP address (xxx.xxx.xxx.131, so I create /etc/sysconfig/network-scripts/ifcfg-eth0:1. Then: # service network restart Shutting down

Hello, I created a CentOS 5.0 x86_64 guest under Debian Etch with Xen 3.0.3 and it boots fine except for one re-occuring problem - whenever it boots the /etc/sysconfig/network-scripts/ifcfg-eth0 script gets renamed to .bak and doesn''t configure the ethernet device. Here is the content of this file: TYPE=Ethernet DEVICE=eth0 BOOTPROTO=static ONBOOT=yes IPADDR=192.168.0.247

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 A few months back, I tried to use the network scripts to provision an IPv6 range like can be done with IPv4. I was using CentOS 5.2 at the time and was informed that 5.2 was broken in this regard. I have upgraded to CentOS 5.3 now and I am trying to get IPv6 to provision an entire range of IPs, but I am still getting the old behavior and no IPs are

So I have a CentOS 5 machine, which I recently did a 'yum update' on. Everything went fine, but I rebooted as a precaution (just to confront any problems which might arise the first time after an update). And sure enough, when the machine came back up, the network didn't work. Luckilly, someone said (and I quote) 'mv /etc/sysconfig/networking-scripts/ifcfg-eth0.bak

Hi all, we are testing CentOS 7 in order to migrate from Scientific Linux 6 / CentOS 6 and we are facing an issue with the network. Trying to configure network with teaming in activebackup mode or also with bonding in mode=1 (active backup as well) we see many RX dropped packets in the bond0 interface (around 10% of the total), 100% RX drops in the backup interface and 0% in the active interface.

Hello list, Postfix is dying on one of my servers almost nightly. This system is running CentOS5 with postfix-2.3.3-2. In the morning (after noticing it died) I try to run `service postfix stop` and I get a failed start. Running `ps ax | grep postfix` I can see one process still running for postfix. After killing this, I am able to run `service postfix start`. I see a lot of this in my

I can't get IPv6 routing to configure correctly despite everything I've read saying it should This is my network config on a fully-updated CentOS 5.8 system: # cat /etc/sysconfig/network NETWORKING=yes NETWORKING_IPV6=yes HOSTNAME=my.hostname.com GATEWAY=aaa.bbb.ccc.ddd IPV6_DEFAULTGW=2a02:aaaa.bbbb::1 IPV6_DEFAULTDEV=eth0 # cat /etc/sysconfig/network-scripts/ifcfg-eth0

Hi, I have x86 system and have used clonezilla to clone the entire hardisk of system A and restored it on another x86 system, system B. After the cloning process, i notice that the MAC address of the system B in the /etc/sysconfig/network-scripts/ifcfg-eth0 is changed and is having the MAC address of system A. The interesting part is that if i do an ifconfig from the bash prompt, the MAC

Hello, I created a module for modifying the base network settings on a machine. However no matter what changes I make it keeps giving me the error "has different MAC address than expected, ignoring" when the network tries to startup. I am testing this out on the puppet learning VM. Does anyone see anything wrong with my code: init.pp -------------------------- define basehost

I want to seriously work with IPv6 and not have stray IPv4 functions messing with me. So in /etc/sysconfig/network, I commented out NETWORKING=yes. I have NETWORKING_IPV6=yes. In /etc/sysconfig/network-scripts I altered ifcfg-eth0, setting BOOTPROTO=none. That was enough for eth0 to only have IPv6 working on it (have IPV6INIT=yes and IPV6_AUTOCONF=yes). But lo had IPv4. So I commented

If so, with what tools?

We've been running ipv6 for a year or so now, but some of our newer instances (all on an ESX cluster) are not working. It looks like it's all of our Centos 6 instances. I'm hoping someone can point me in the right direction... tshark indicates that it's neighbor discovery that's failing: <centos666.peak.org> [26] # cat ../network NETWORKING=yes
