As the test description says:
The IP addresses are assigned statically by venus based on the
user-defined MAC address derived by the dhcpplugin from a hash over
the client identity. This deterministic MAC generation is activated
with the strongswan.conf setting charon.plugins.dhcp.identity_lease =
yes.
This is not a real MAC address, but one generated on behalf of the
client, based on its identity. With that identity_lease option, the
generation is deterministic, so you'll get the same MAC for the same
client identity. This makes the DHCP server handing out the same IP for
the same client identity each time.
Thanks for your explanation, but my question is: If I want to add another host,
i.e., Tina along with Dave, who also need a static mac address in DHCP server
configuration,
how does this static mac address come out in the first place before any IKE
contact?
I read the code, chunk_mac_inc performs SipHash-2-4 when IKE contact actually
happens.
Alternatively, you may assign addresses for specific client identities
on your DHCP server using the dhcp-client-identity option; see
ikev2/dhcp-static-client-id.
Yes, dhcp-static-client-id test is quite straight forward.

Martin
