So...
I need to do a quick and dirty turn off of IPv6 addressing. Currently I
have:
# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
BOOTPROTO=none
ONBOOT="yes"
TYPE="Ethernet"
NAME="System eth0"
MACADDR=02:67:15:00:01:80
MTU=1500
DNS1=208.83.67.148
GATEWAY="208.83.67.177"
IPADDR="208.83.67.180"
NETMASK="255.255.255.240"
HOSTNAME="z9m9z.htt-consult.com"
IPV6INIT="yes"
DNS2=2607:f4b8:3:0:67:15ff:fe00:148
So if I set IPV6INIT="no" and drop DNS2, I should be turning off IPv6?
Is there anything else? /etc/sysconfig/network does not list IPv6 as
it use to in days past...
This appears to have disappeared in the depths of my inbox and I only
just found it.
Try:
sysctl -w net.ipv6.conf.all.disable_ipv6 = 1
sysctl -w net.ipv6.conf.default.disable_ipv6 = 1
To make it happen on every boot, put the relevant entries in
/etc/sysctl.conf
