[Devil-Linux-discuss] IPv6 address and ifcfg-ethX

[Rick F. <ri...@gr...>]

I decided to finally jump in to IPv6 with my devil-linux firewall. Using 
latest stable version of 1.6.2 with the free IPv6 tunneling service from 
Hurricane Electric where they will assign up to five /64 IPv6 networks.

I was not able to configure the LAN interface with an IPv6 address using 
/etc/sysconfig/nic/ifcfg-ethX.  Found that configuring the IPv6 address 
using the IPV6ADDR variable did not work at boot.  When one or more 
addresses were configured, I received "RTNETLINK Operation not 
permitted".  However running same command after boot (ip -6 addr add 
$v6addr dev $DEVICE) worked fine.  Found problem due to "ipv6" module 
was not loaded prior to configuring interface addresses.

The ipv6 module is loaded later on in /etc/init.d/network if 
START_IPV6_ROUTING is turned on in master config.  However, that is done 
after the section to add IPv6 addresses (and routes) from the interface 
config files.

I applied a workaround in boot.local to load ipv6 module in advance of 
running network rc script.  A better solution might be for the network 
script to make sure ipv6 module is loaded prior to adding any IPv6 
addresses or routes from the interface config files (similar to 
START_IPV6_ROUTING section).

Let me know if I overlooked something that prevented me from having to 
preload ipv6 module with boot.local.  Be glad to assist with any 
changes/testing.
