I'm having an awful time trying to get NTP working on some new servers.
Consider three machines:
jeffy: my home machine, runs 5.4 with a very sleek kernel, sits behind a ro=
uter.
web1: one of the new servers, running 5.4-p2 with a kernel
configuration that *only* has options INET6 commented out:
root@web1# diff GENERIC WEB
25c25
< ident GENERIC
---
> ident WEB
32c32
< options INET6 # IPv6 communications protocols
---
> #options INET6 # IPv6 communications protocols
web2: another of the new servers, running 5.4 with GENERIC
All three have the same /etc/ntp.conf:
server sundial.columbia.edu
driftfile /var/db/ntp.drift
All, of course, have ntpd_enable=3D"YES" in /etc/rc.conf
Here are the relevant lines from the log when I run /etc/rc.d/ntpd
start, after making sure it is stopped, of course. When any of them
is stopped "netstat -n | fgrep 123" yields no lines.
jeffy:

web2:

'ntpq -p' on jeffy returns a normal looking ntpq result. 'ntpq -p' on
either web1 or web2 eventually times out. However, if I put a
"restrict" into their ntp.conf I get something like
remote refid st t when poll reach delay offset jit=

that never changes, even after several hours.
I've read a lot of similar problem reports, but none of them ever seem
to have a definitive answer.
Can anyone help? I'm really mystified.
The only thing I have left to try is that I have noticed that jeffy
has NO_INET6 =3D true set in /etc/make.conf, whereas web1 does not have
this.
