I am having problems with the NTP client end of the software the comes
as part of Red Hat 7.3. I am talking to a RH 7.2 NTP server, and
before I upgraded my notebook to 7.3 (it was vaguely at 7.2) it could
get the time, and now it can't.
When I ask it what it is doing, it just sits there:
[root@spot etc]# ntpq -p
remote refid st t when poll reach delay offset jitter
==============================================================================
*LOCAL(0) LOCAL(0) 10 l 35 64 177 0.000 0.000 0.008
borg.org 0.0.0.0 16 u - 64 0 0.000 0.000 4000.00
[root@spot etc]#
If I do a tcpdump while I do an /etc/init.d/ntpd restart, and then
another ntpq -p, I get:
[root@spot etc]# tcpdump
tcpdump: listening on eth0

Note, the "chargen" is really an ssh session into my server, I run it
on port 19 because my ISP blocks the correct ssh port for some reason...
Ideas?
Thanks,
