[gentoo-user] ntp-daemons

[Stefan G. Weichinger]

I always used net-misc/ntp for syncing time.

Now I found net-misc/chrony and set it up .... looks good so far.

Any opinions and experiences on the various ways of getting THE TIME?

Interesting ;-)

Switched to chrony on 4 machines already and like it ...

Just two different hammers for the same nail. Another alternative is 
OpenNTPD btw, http://www.openntpd.org/

Sure. I just like the quicker syncing/adjusting of chrony.

I will have a look as well ;-)

Thanks, Stefan

I use chrony on a box of mine and found that it is listening for connections 
on UDP 123 - I assume it is running as a server.  I didn't find a way of 
switching this off though.

I've been using chrony for years now. It always seems smooth and simple to 
me - apart from a silly log message that's emitted any time it goes for a 
time source it hasn't seen before. Instead of saying it's created a new log 
file for it, it says it's failed to open the log file. And then it just 
creates it anyway.

Ho hum...

Yes, I noticed the same here.

Do you have chronyc set up to signal off/online status to chronyd?  If so, 
where do you run it from?

No, I don't need to bother with manual control: it just works for me. I did 
play with chronyc years ago but I soon got bored.

I have chronyd running on my LAN server, getting its time from several hosts 
Out There, then internal hosts get their time from the LAN server. All very 
straightforward. Any time errors just ramp themselves steadily down to zero. 
I can show you my config files if you like.

In those old 486/586 days the author used to publish a new version for each 
new generation of CPU, but I haven't seen that since x86_64 came on the 
scene. I suppose he must have found another way of calibrating his object 
code's execution time. Whatever the case, I'm happy that gkrellm etc. show 
the time to at least the nearest half-second relative to BBC time signals.

I started using chrony in those old dial-up days because it can handle slow 
links. Also intermittent ones, by which I mean systems that shut down for 
some of the day, or that dual-boot with Windross,. I haven't felt a need to 
change since then. At that time ntpd was at a disadvantage IIRC. You might 
say that chrony is designed for desktop boxes rather than the servers that 
ntpd likes, though the edges are pretty blurred.
