Hi, I just found the SYNCHRONISATION section of the dhcpd manual page. Sounds great - thanks for again implementing such a nice simple feature into OpenBSD.
I also had a look into dhcpd.c and sync.c and with my limited knowledge tried to answer the following question: Is there any mechanism to compensate for a member of the synchronisation group being offline and coming back online after the other member(s) have generated new leases? As far as I understand, the member that is coming back online does not get bulk updates as it is the case with CARP and pfsync. Am I right, that the user of such a setup is expected to fetch a current copy of dhcpd.leases before he starts dhcpd in sync mode? Or is there some other mechanism I did not see? Kind Regards, Christian
