Okay sorry about that. No Idea if it will work in CentOS, but is it worth trying to turn off ipv6 for a single nic as as outlined at https://coreos.com/os/docs/latest/network-config-with-networkd.html ?

That's ok the link was a good idea however, it doesn't fix the issue with disabling ipv6 at the kernel level, fails with the same output Regards On Wed, 4 Oct 2017 at 14:39 Clint Dilks <clintd at scms.waikato.ac.nz> wrote:> Okay sorry about that. > > No Idea if it will work in CentOS, but is it worth trying to turn off ipv6 > for a single nic as as outlined at > https://coreos.com/os/docs/latest/network-config-with-networkd.html ? > > > > > On Wed, Oct 4, 2017 at 4:14 PM, Phil Manuel <phil at zomojo.com> wrote: > > > Hi Clint, > > > > systemd-networkd doesn't use those files at all. > > > > > > > > On Wed, 4 Oct 2017 at 13:55 Clint Dilks <clintd at scms.waikato.ac.nz> > wrote: > > > > > On Wed, Oct 4, 2017 at 3:46 PM, Phil Manuel <phil at zomojo.com> wrote: > > > > > > > Hi, > > > > > > > > If I disable ipv6 via the kernel command line, ipv6.disable=1, then > > > > systemd-networkd fails to bring up any interfaces. > > > > > > > > Removing the option and networking works as expected. > > > > > > > > > > Hi, > > > > > > If you look at the appropriate ifcfg files eg > > > /etc/sysconfig/network-scripts/ifcfg-em1 do you see > > IPV6_FAILURE_FATAL=no ? > > > _______________________________________________ > > > CentOS mailing list > > > CentOS at centos.org > > > https://lists.centos.org/mailman/listinfo/centos > > > > > _______________________________________________ > > CentOS mailing list > > CentOS at centos.org > > https://lists.centos.org/mailman/listinfo/centos > > > _______________________________________________ > CentOS mailing list > CentOS at centos.org > https://lists.centos.org/mailman/listinfo/centos >

Files in /etc/systemd/network if I'm remembering right... been awhile since I played with it and it's not in a standard rhel install. You use .network files to do network configuration and .link for link level stuff like mac address.
