Re: switching off IPv6?

[Christian Rohrmeier SCHERING DE]

Hi Klaus,

here is how I deal with it in my %pre script:

# Turn off IPV6 #
# In /etc/sysconfig/network
echo "NETWORKING_IPV6=no" >> /mnt/sysimage/etc/sysconfig/network
# In /etc/sysconfig/network-scripts/ifcfg-eth0
echo "IPV6INIT=no" >>
/mnt/sysimage/etc/sysconfig/network-scripts/ifcfg-eth0
echo "IPV6INIT=no" >>
/mnt/sysimage/etc/sysconfig/network-scripts/ifcfg-eth1
# And because the above doesn't work because of a bug, we force it in
# /etc/modprobe.conf as well.
echo "alias net-pf-10 off" >> /mnt/sysimage/etc/modprobe.conf

As noted in the comments, there is a bug in the networking scripts: 1) IPv6
shouldn't be turned on by default in the first place, 2) the options to
turn off IPv6 explicitly are ignored. The addition to modprobe.conf is
actually what works. It requires a reboot to take effect, since, as you
noted, you can't remove the modules once they are in use.

Cheers,

Christian

Is there a quick way to switch -off- IPv6 in Kickstart? By the time I've
got a
system fully configured, it gets loaded by default and marked as 'in use'
if I
try to rmmod (I assume simply adding an IPv6 address to a NIC makes it
so?).

Any suggestions are welcome.

Klaus
