[Kea-users] [EXTERNAL] Re: Inter-process communication with the kea server?

[David Farje]

Hi Fred,


David, a Unix Domain Socket sounds like a good fit. What I want to have
happen

over the socket is for my application to mimic a DHCPv6 Client and request
IA_NA

and/or IA_PD delegations from kea acting as the DHCPv6 Server.


Is that possible?


I don't think this is possible. The only thing exposed via the unix socket
is a control channel.

The actual implementation of DHCP will always require a network stack.

If you want to keep  DHCPv6 communications local try to use localhost or
virtual interfaces.
