We tested a subset in versions 0.4.1 and 0.4.2:
- DHCPv6 client mode
- DHCPv6 server mode
- DHCPv6 stateful and stateless operation
- Address assignment
- Information on DNS options — nameserver address and the clients’ domain-name
Other options and functionality were not tested.
Client DHCPv6 configuration
Stateful DHCPv6
In our tests, Dibbler 0.4.1-1 (on Linux) and 0.4.1 (on Windows XP) was configured for a stateful request for an address assignment and DNS information.
The configuration file client.conf:
iface if {
(if is the used interface. This could be e.g. eth0 (on Linux) or
"LAN connection 1" (on Windows).)
ia
option dns-server
option domain
}
Stateless DHCPv6
In our tests, Dibbler 0.4.1-1 (on Linux) and 0.4.1 (on Windows XP) was configured for a stateless request for DNS information.
The configuration file client.conf:
iface if {
(if is the used interface. This could be e.g. eth0 (on Linux) or
"LAN connection 1" (on Windows).)
stateless
option dns-server
option domain
}
Server DHCPv6 configuration
Stateful DHCPv6
Dibbler 0.4.2-CVS was used as stateful DHCPv6 server under Linux, offering stateful address assignment from an address pool (see example).
The following configuration file server.conf was used:
log-level 8
(if is the used interface. This could be e.g. eth0 (on Linux) or
"LAN connection 1" (on Windows).)
log-mode long
iface "if" {
class {
pool 2001:db8:dead:beef::100-\
2001:db8:dead:beef::200
}
}
