Okay, this spurred me to try again with my setup. The idea is to have one
machine sync to the outside, then all others on the lan sync to that one.
For some reason, I cannot reach my server by name--even with an entry in
/etc/hosts. My ntp.conf file uses the ip addy anyway, but when I run peers:
ntpdc> peers
remote local st poll reach delay offset disp
=======================================================================
*LOCAL(0) 127.0.0.1 10 64 377 0.00000 0.000000 0.00095
=philo.localdoma 5.0.0.0 16 1024 0 0.00000 0.000000 0.00000
somehow it resolved the name, but as you can see, no connection.
My version of ntpd doesn't have -q, but since I can't do 'host philo', it
wouldn't work anyway.
Main question: how the hell do you get the machines to resolve by name?
This used to work until I upgraded one of the machines. Presumably, my
gateway router is handling the internal dns stuff, but shouldn't a direct
entry in /etc/hosts override?
127.0.0.1 rufus.localdomain localhost rufus
192.168.0.100 philo.localdomain philo
