redetect-interfaces command
The idea is to tell Kea to redetect network interfaces. There's re-detect
flag in interfaces-config
that can be used in config-set
. But this requires a general heavy-weight reconfiguration of the whole server.
The idea here is that Kea could be told that some new interfaces appeared or disappeared (VLAN, PPP, some other tunnel etc.) and Kea should redetect them. For an added bonus, there should be a way to tell Kea to open sockets on those new interfaces. This can be done either by telling Kea to open the on any newly detected interfaces or perhaps return a list of interfaces and have a dedicated call open-socket
or something similar? Anyway, this would be useful to have a mini-design for.
This problem is not new and there are many requests in this problem space:
