Hi,
On a system running FC3 I have 2 NIC cards. I would like to activate IPv6 only on one card and only IPv4 on the other one.
My /etc/sysconfig/network-scripts/ifcfg-eth0 looks like:
DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
TYPE=Ethernet
NETMASK=255.255.255.0
IPADDR=192.168.1.10
USERCTL=yes
PEERDNS=yes
GATEWAY=192.168.1.1
IPV6INIT=no
IPV6_AUTOCONF=no
And when running:
/etc/init.d/network restart
I still have IPv6 active on eth0 and autoconfiguration running..
Any ideas ?
Google found this
http://www.mjmwired.net/resources/mjm-fedora-fc3.shtml
[snip] To disable IPV6: As root, you must add the line: "alias net-pf-10 off" (without quotes) to the end of your /etc/modprobe.conf file.
-OR-
Quick solution:
[root@charon fc3]# echo "alias net-pf-10 off" >> /etc/modprobe.conf
A reboot is required.

Which totally disables IPv6 on the system, not what the OP wanted to do.


Yep, my fault. I just read disable ipv6 and... nevermind :-)

I would guess my eth0 wouldn't listen to ipv6 from now on...
