I updated to 0.6.2 a week or so ago (on my net5501), and just discovered today that my date is all screwed up. I had been running 0.6-2082 prior to that, so I went back to that version, with no apparent changes. So, I've been less than observant for some time now. In my defense, I have a box for screwing around with, and a real 5501 for being a pbx and actually working. That one is fine. (running the old-timer trunk-1725).
At first, I thought that this was the same issue as the NTP mixup posts from
a few weeks ago, but further scrutiny shows differences.

The end result is a couple of ntpd zombies and a date back in March 1980.
sk3 log # ps -w | grep ntpd
1521 root Z [ntpd]
1522 root Z [ntpd]
This is very repeatable, as I can run /etc/init.d/ntpd start and get the
same results from the cmd line. (BTW, there isnt' anything else occupying
ports 123, I checked netstat)
I modified the ntpd startup script to strace ntpd and found the following
relevant system calls and status:
if nslookup $first >/dev/null; then
# Set the clock (large change) and exit
strace -f ntpd -g -q -c /etc/ntpd.conf
sleep 1
# Maintain the clock (small changes)
strace -f ntpd -c /etc/ntpd.conf
The results were as follows. Note the two bind calls IPV4 - works, and IPV6
- which fails with the EADDRINUSE
setsockopt(16, SOL_SOCKET, SO_REUSEADDR, [0], 4) = 0
bind(16, {sa_family=AF_INET, sin_port=htons(123),

Additional notes:
- firewall port(s) are open, for what that is worth. I don't think
that is the issue. My other net5501 works fine with astlinux-1725 and the
ports aren't open there. NTP client shouldn't need it open, I don't think.
- I went into rc.conf and made IPV6=NO, (It was commented out). To no
avail.
Any thoughts ?
