Running current Fedora 25.
How should I supersede the nameserver when using IPV6 and dhclient?
If I enable IPV6, my dhclient.conf doesn't work as I'd expect, it works as expected if only IPV4 is enabled.
I have this:
# cat /etc/dhclient-enp6s0.conf supersede domain-name-servers 127.0.0.1;
# grep V6 /etc/sysconfig/network-scripts/ifcfg-enp6s0 # IPV6INIT=no DHCPV6C=yes
And then if I restart the interface:
# ifdown enp6s0 > ~/ifdown.out 2>&1 ; ifup enp6s0 > ~/ifup.out 2>&1
I get:
# cat /etc/resolv.conf ; generated by /usr/sbin/dhclient-script nameserver 2001:558:feed::1 nameserver 2001:558:feed::2
If I disable IPV6, it works as I'd expect:
# grep V6 /etc/sysconfig/network-scripts/ifcfg-enp6s0 IPV6INIT=no # DHCPV6C=yes
# ifdown enp6s0 > ~/ifdown.out 2>&1 ; ifup enp6s0 > ~/ifup.out 2>&1
# cat /etc/resolv.conf ; generated by /usr/sbin/dhclient-script search hsd1.or.comcast.net. nameserver 127.0.0.1
Thanks ...
