similar to: 1st static IPv6 address

So I do not want to run radvd on my public subnet (between the gateway and firewall). I am trying to set up the firewall's public interface. For now in ifcfg-eth0 I have the lines: DEVICE=eth0 BOOTPROTO=static HWADDR=00:40:F4:05:A8:F1 IPV6INIT=yes IPV6_AUTOCONF=no IPV6ADDR="2607:F4B8:3:1:0:40:F405:A8F1" ONBOOT=yes And in network I have: NETWORKING=yes NETWORKING_IPV6=yes

-----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

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

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

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

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

How about, in your /etc/sysconfig/network file adding or editing the line for IPV6 to be: NETWORKING_IPV6=no and then try a 'service network restart' and see what you get.

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

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 met a problem in configuratiion of ipv6 gw in my box i install centos 6.3 (64 bit) on my boxs, which have four netcard. i use a straight-through cable to connect centosv0:netcard-2 and centosv1:netcard2 the topology is this: client c(windows xp) <-->centosv0:netcard-3 <--> centosv0:netcard-2 <---> centosv1:netcard-2 <---->centosv1:netcard-2 <---> client d

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

Try: sysctl -w net.ipv6.conf.all.accept_ra=1 to persist between boots, be sure to add this to your /etc/sysctl.conf file. This should prevent the box from listening to any RA announcements.

No change after running this and trying both: system network restart ifdown eth0; ifup eth0 Still having an IPv6 addr. The box has been up for 140 days. Would like to keep it running... This box is really Redsleeve 6, which is the port of Centos 6 to arm. The kernel I am using is the F19 kernel. All of this MIGHT be contributing to things not working as they would on a 'normal'
