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:...

-----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

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, 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, 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 have a test system that I am using to investigate CentOS-7. I note the following difficulty when booting from the Minimal Install DVD. Neither on the initial install nor on subsequent attempts at re-installing CentOS-7 can I set the IPv4 interface to a static IP address. I can configure it but I cannot save the changes. The save button remains greyed out. -- *** E-Mail is NOT a

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

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'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?
