similar to: Configuring ipv6 reboot persistence, CentOS 5.6

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

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

Hello, in /etc/sysconfig/network-scripts/ifcfg-eth0 I have this <ifcfg-eth0> ...

-----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

Hello, I''m reading this guide on ipv6 (really just getting my "feet wet"): http://www.shorewall.net/6to4.htm In the section "Configuring IPv6 using my script" I can read that the IPv6 interfaces are: INTERFACES="eth2 eth4" and that correlates fine with the first diagram/figure. However, further down I read "You will notice that sit1, eth0 and eth2

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

I have a second server and gave it a WAN address and I can connect between them using their WAN addresses. That's what told me that my ip6tables weren't screwed up and that the problem lay elsewhere.

CentOS 5.5, fully patched. I have a HE tunnel (tunnelbroker.net) IPv6 tunnel. This works pretty well and is simple to setup. Everything works fine. Until I try to set up an ip6tables firewall. eg if I try to view https://dnssec.surfnet.nl/?p=464 then the page never displays and the firewall shows kernel: IN=sit1 OUT=eth0 SRC=2001:0610:0001:40cd:0145:0100:0186:0033 DST=my.machine LEN=80 TC=0

Hello Because I did not send , and then retransmitted. I am using the CentOS5.7. In a state where the link down, I did a ping to the IPv4 and IPv6. IPv4 succeeds in ping. but, IPv6 is ping fails. Once confirmed by ifconfig, it did not have a Link-Local Address. At link down, Is the Link-Local Address not set? Leave the link down, Is there a way to avoid this? # ethtool eth1 Settings for eth1: ?

I've been trying out IPv6 networking with tinc and noticed that it will not route smaller segments than /48 If I try to run ip -6 route add aaaa:bbbb:cccc:dddd::/64 dev tun0 I get network unreachable However if I run ip -6 route add aaaa:bbbb:cccc::/48 dev tun0 it works fine Is this is a limitation in tinc or the kernel network stack itself? -------------- next part -------------- An HTML

Hi, I have a kvm host and I try to install a centos 6 guest with a static ip address. When I do a manual install I eventually get to the network configuration and if I enter IP, gateway and DNS Server I can ping6 the guest from the host and I can ping6 the guest from outside. I do not want to do manual installation, so I have to specify a url to a kickstart file, but to download it the network

Hi, I have a process which is running as a linux service and assigns IP addresses using netlink to configued interface in linux. For IPv4 addresses i do not see any issue with this assignment. When i try to assign an IPv6 address, the address gets assigned successfully to the interface, but the Neighbour Solication request received for that address is not responded with and hence ping6 from a
