OK, that makes sense. You'd think all decent DNS and DHCP servers out there would support any old arb db backend (very useful, no?) but it seems not. I've gotten used to independently vi'ing two files and HUP/reload two daemons over the years :-) Bind can use a mysql backend, so can most auth servers. The only dhcp server easily available on gentoo seems to be dhcp from ISC which does not support mysql. But both support ldap, maybe you can use that? There's lots of ldap frontends so getting your info into it should be easy enough. You could also look into kea (https://www.isc.org/kea/), a better dhcp server from ISC. The blurb says it supports SQL backends. -- Alan McKinnon alan.mckin...@gmail.com
