IPv4/IPv6 starting scripts

krik · #1 April 10th, 2010, 07:36

Hi,

I'm trying to setup a dual stack IPv4/IPv6 server and I can't find which rc.d script to run...

I've started the server without any IP then I've put the following into rc.conf

Code:

#IPv4 config
ifconfig_re0="inet 192.168.1.10 netmask 255.255.255.0"
static_routes="default"
route_default="default 192.168.1.1"

#IPv6 config
ipv6_enable="YES"
ipv6_ifconfig_re0="2001:db8:abcd::e/56"
ipv6_static_routes="default"
ipv6_route_default="default 2001:db8:abcd::1"

Then I've started the network with the following scripts:

/etc/rc.d/netif start
/etc/rc.d/routing start
/etc/rc.d/network_ipv6 start

The IPv4 is working perfectly, the IPv6 defined address is there but the link-local address is missing. If I reboot the server everything is there... What script do I need to start/restart to get the link-local address without rebooting?

Thanks for your help ,
Christophe

A quick grep of /etc/rc.d/ for ipv6 will show you the answer (# grep ipv6 /etc/rc.d/*).

There are separate IPv4 and IPv6 scripts for networking, routing, firewalling, etc.

Also, check the output of rcorder to see which order to call things: # rcorder /etc/rc.d/* /usr/local/etc/rc.d/*

Thanks for the advise, I've at least learn a new command... I didn't knew rcorder. But unfortunately it doesn't work... I've restarted all the scripts containing ipv6 in the order shown by rcorder but the link-local ipv6 address is still missing.

I think it has to do with the net.inet6.ip6.auto_linklocal sysctl. Which gets set in /etc/rc.d/auto_linklocal.

Just about to post that after a # grep -rl "::1" /etc

I remembered some fuss about ipv6 and specifically link-local addresses with the beta/rc of 8.0

Got it!

As stated by SirDice, the script # /etc/rc.d/auto_linklocal set net.inet6.ip6.auto_linklocal to 0 and prevents # /etc/rc.d/netif to add the link-local address... When I set net.inet6.ip6.auto_linklocal to 1 and then restart # /etc/rc.d/netif the link-local address is automatically set.

Now the issue is that restarting netif brings down all the network interfaces what I tried to avoid by not rebooting the server.

Thanks for your help!

It should bring them right back up, but you'll need to restart /etc/rc.d/routing as well after that.
