Centos 6 - disabling IPv6 addressing
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.

Centos 6 - disabling IPv6 addressing
Sorry - that should be
sysctl -w net.ipv6.conf.all.accept_ra=0
to disable that, not 1.

IPv6 range provisioning question
-----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

nmcli: unwanted secondary ip-address
Dear Simon,
every second IP-address is unwanted. We restarted? eno4:
nmcli con down eno4; nmcli con up eno4
and the second address vanishes. Then after a few ours, the second ip
address reappears.
This is the config-file of eno2:
# cat ifcfg-eno2
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=none
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes

Configuring ipv6 reboot persistence, CentOS 5.6
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

What is the correct combination of packages to configure and manage
VMs via virt-manager undet CentOS-5.4? If I use qemu then while
virt-manager works I obtain SELinux alerts with respect to the
real-time clock. If instead of qemu I use kvm-qemu-img then
virt-manager simply does not work. It starts but it does not find
any form of qemu and the selection boxes are all greyed out.

I'm not seeing any outbound IPv6 traffic from my CentOS 7 box on the WAN

7.7.1908, interface bonding, and default route
Hi!
I just upgraded a machine to 7.7.1908 and the default route is not being
set on boot. This particular server has a bonded interface, and the
corresponding configuration for the master is (
/etc/sysconfig/network-scripts/ifcfg-bond0):

True bond howto for Centos 6
Hi all,
Read many posts on the subject.
Using 802.3ad.
Few problems;
Cannot ping some hosts on the network, they are all up.
Cannot resolve via DNS which is one of the hosts that I cannot ping, internal nor external DNS hosts.
Unplugging the NICS and plugging them back in will then not allow pining if the default d=gateway.
When cold booting it somewhat works, some hosts are pingable while

Help with routing question.
CentOS-6.6
We have a host that has multiple IPv4 addresses aliased to eth0. The
primary address is 216.185.71.x and the alias is 192.168.6.x.
This host connects to devices on both netblocks without problems.
Only default routing is used and it looks like this:
#ip route
192.168.6.0/24 dev eth0 proto kernel scope link src 192.168.6.x
216.185.71.0/24 dev eth0 proto kernel scope link src

Dashboard parameters to control VIPs?
Some of the Red Hat Enterprise Linux servers in our environment
sometimes get assigned virtual IP addresses (eth0:1, eth0:2, etc).
Puppet Dashboard''s parameters seem like an ideal way to define and
provision virtual IPs on these servers. One could create a "vip1"
parameter on a node, and define a value of the IP address to use for
that vip. A manifest could then be written to
