Hello; I've run into a rather interesting problem on CentOS 7. According to sysconfig.txt (part of the initscripts documentation), I can set the following variables in ifcfg-ethX: DHCPV6C="yes" DHCPV6C_OPTIONS="-S" I've done so, but nothing is populated to /etc/resolv.conf and so DNS does not work. Interestingly, if I remove the latter option, an IPv6 address is

Hey, I have a setup that has one machine communicating to a server using UDP over IPv6. For specifics, it is using collectd with a boosted MaxPacketSize in the network config. What this means is there is some IP fragmentation happening, and that is getting REJECTed. My policy is to REJECT, and I have an ALLOW for the particular communication I want. What I''m getting in my logs is

Machine is an internal server with zero need to provide or receive ip addresses using dhcp (all IPs are hard coded). Question: how do I disable dhcpv6-client on this box?

Is there an DHCPv6 client in CentOS that supports prefix delegation correctly? The old version of dhclient can't set a requested prefix delegation length, so isn't very useful, and I can't get the even-older wide-dhcpv6 from EPEL to work. -- Chris Adams <linux at cmadams.net>

If you select an option that's not listed during ipv4/ipv6 setup it will accept it without verification. This corrects that behavior and forces a valid option to be picked. --- scripts/ovirt-config-networking | 106 +++++++++++++++++++++------------------ 1 files changed, 58 insertions(+), 48 deletions(-) diff --git a/scripts/ovirt-config-networking b/scripts/ovirt-config-networking index

I just got 50 Mbps symmetric fiber from AT&T and it includes a /56 of IPv6 addresses, replacing a much slower ADSL line. I never tried to get IPv6 working on the old connection. I'm using CentOS 7 as a gateway and it's worked great for several versions for IPv4. I'm not seeing any IPv6 default route on the WAN interface. I suspect I'm not getting route announcements. I
