I know it's not good form to reply to ones own post, but I added a couple of
lines to /etc/rc.d/rc.local to stop and start ntpd.
Now when I bootup FC2 with no Internet connection, and then connect to the
Internet through the Smoothwalls web interface, then run ntpq> pe, I get only
one of the 3 Internet time servers showing, which eventually sets itself as
sys.peer. Quite why only 1 server is showing is a mystery. If I now stop
and start ntp, and run ntpq> pe again, all 3 servers are displayed.
By contrast, FC6 on the same machine, which is using ntp-4.2.4p0-1.fc6 has no
such problems. I boot it up with no Internet connection, then connect via the
Smoothwalls web interface, then run ntpq> pe, and all 3 servers are listed,
plus local. These are the default servers that come with FC6.

Local was set as sys.peer almost instantly, and the sys.peer was moved to the
GPS server in perhaps 2, or 3 minutes, and a couple of minutes later the
other 2 servers were set as candidat's. This is all a lot quicker than it has
ever progressed in FC2.
Do you think it's worth removing the current ntp from FC2, and installing from
tarball the latest version available?
It would be nice to resolve this problem on FC2.
Nigel.
