Like I say, I *have* fedora, I'm not planning to uninstall it as it was
installed for me and I don't want the hassle. HI

Jeroen,
I have v2.1 v2.2 of the PDF Manual. No real differences that I can see, just
a couple non-necessary pages.
The only other bit of info I have that might be of some use, I saved the
startup text a while back, it should look something like

Dave,
Fedora will be fine as a basic network time server. If NTP isn't already
installed on the system, all you have to do is type (as
root):
yum install ntp
The default config usually queries the NTP Pool. Depending on where you live
you might want to edit the file to use only your
country's

You might consider switching to FreeBSD for more reasons than just
timing, It's much faster than Fedora and I found the new 7.1 version easy
much faster in what respect? tested how?

Anyone got any good Linux time systems for PCs ?
Make sure you have a recent kernel installed with the PPS patch applied:
remote refid st t when poll reach delay offset jitter

The usual benchmark that's cited here is the mysql tps scaling better

Hi Ulrich,
mind. On the other hand: If a good timing receiver has ended his site

Obviously that is not what you expect from a navigation system. Keep
navigation and timing receivers clear apart from each other. They are
