DHCPv6 can be used for stateful configurations. The daemon itself need not necessary run on the Linux default IPv6 gateway router.
You can specify more information than by using radvd. The are most similar to IPv4 DHCP server.
After a proper configuration, the daemon reacts on received ICMPv6 multicast packets sent by a client to address ff02::1:2
dhcp6s's config file is normally /etc/dhcp6s.conf. An simple example looks like following:
interface eth0 {
server-preference 255;
renew-time 60;
rebind-time 90;
prefer-life-time 130;
valid-life-time 200;
allow rapid-commit;
option dns_servers 2001:db8:0:f101::1 sub.domain.example;
link AAA {
range 2001:db8:0:f101::1000 to 2001:db8:0:f101::ffff/64;
prefix 2001:db8:0:f101::/64;
};
}; |
dhcp6c's config file is normally /etc/dhcp6c.conf. An simple example looks like following:
interface eth0 {
send rapid-commit;
request domain-name-servers;
}; |
The server has one foreground and two debug toggles (both should be used for debugging), here is an example:
# dhcp6s -d -D -f eth0 |
As general debugging for test whether the IPv6 DHCP server is reable on the link use an IPv6 ping to the DHCP multicast address:
# ping6 -I eth0 ff02::1:2 |
The client has one foreground and two debug toggles, here is an example:
# dhcp6c -d -f eth0 Oct/03/2005 17:18:16 dhcpv6 doesn't support hardware type 776 Oct/03/2005 17:18:16 doesn't support sit0 address family 0 Oct/03/2005 17:18:16 netlink_recv_rtgenmsg error Oct/03/2005 17:18:16 netlink_recv_rtgenmsg error Oct/03/2005 17:18:17 status code for this address is: success Oct/03/2005 17:18:17 status code: success Oct/03/2005 17:18:17 netlink_recv_rtgenmsg error Oct/03/2005 17:18:17 netlink_recv_rtgenmsg error Oct/03/2005 17:18:17 assigned address 2001:db8:0:f101::1002 prefix len is not ¬ in any RAs prefix length using 64 bit instead Oct/03/2005 17:18:17 renew time 60, rebind time 9 |
