Re: [9front] non-9front dhcp server -> /lib/ndb/local ignored?

[Steve Simon <steve@quintile.net>]

maybe being foolish, but from memory - the config you see does not include a dnsdomain= entry so dns(1) does not know which names are local and which are not.

in you example you use ping, does that work with a fully qualified domain name?
