just like my degree ...
I was trying to change my DNS config on the command line (why? because I'm
not in front of my machine), and didn't even consider that the UN*X or at
least FreeBSD and Linux standard of /etc/resolv.conf would be
used by OSX. Not an unfounded assumption, given e.g., the comments at the
head of /etc/hosts.
Anyway - it is used, but - weh-hey - it doesn't have to be! You can use
a netinfo database instead. Try a nidump -r /locations/resolver /
to see what, if anything, you've got there already. If nothing, then create
a new path with niutil -create / /locations/resolver. Add
keys with niutil -createprop / /locations/resolver nameserver
<your nameserver> and niutil -createprop / /locations/resolver domain
<your domain> if you want to search a domain as well. (If you need more than one DNS entry, it looks like niutil -appendprop does the
job.)
To test it: move /etc/resolv.conf somewhere else,
and send a SIGHUP
to lookupd with
kill -HUP `cat /var/run/lookupd.pid`. Then ping some computer or other
and see that the name resolves.
Hopefully the network system preferences pane should pick these changes up .. I just need
to get home and check. And one day maybe I'll tweak the cache settings in lookupd, which is sometimes a little sluggish (that might be my ISP though).
