Here is my complete ntp.conf: # Name of the servers ntpd should sync with # Please respect the access policy as stated by the responsible person. #server ntp.example.tld iburst server pool.ntp.org This chooses a single random server from the pool to sync with, which is probably not /exactly/ what you want. You have a few alternatives: 1) Change server to servers. Then, ntpd will use all the IPs associated with the domain name. As part of the process of syncing it will invalidate peers that have long or volatile round-trip times. It will, however, try to connect to 100s (IIRC) of IPs initially. 2) Use: server 0.pool.ntp.org server 1.pool.ntp.org server 2.pool.ntp.org In this case, the daemon will only use the first address from each domain name. n.pool.ntp.org (for n = 0-9, IIRC) resolves to the same addresses as pool.ntp.org, but the primary address you get back is different each time. (I believe the n. prefix is an attempt to prevent local caching, which would be a problem if you just repeated your server line 3 times.) You'll get better times syncing off multiple servers because the daemon can use some statistics to remove some of the network latency issues. However, you could still get a bad draw and get 3 servers far away from you. 3) Follow this comment from *your* .conf file: # A good way to get servers for your machine is: # netselect -s 3 pool.ntp.org netselect is available from portage, and I think it's generally installed during your gentoo install as a dependency of mirrorselect. In any case, you can use it to find 3 (or however many you want to use) servers close to you. Unfortunately, with this method, if better peers are added to the pool, the network topology changes, or anything else to invalidate the quality of the peers you pick, ntpd won't be able to automagically pick better ones. Also, for any of these options, you should note the geographic sub-pools that are available. I use us.pool.ntp.org. For (1) this will reduce the number of IPs initially connected to, for (2) it will increase the chance that you don't get a bad draw (because, generally, geographically closer is closer on the network), for (3) ... Well, actually for 3 you might as well pick the best ones from the entire pool. -- Boyd Stephen Smith Jr. [EMAIL PROTECTED] ICQ: 514984 YM/AIM: DaTwinkDaddy -- gentoo-user@gentoo.org mailing list

Check ntp.your isp here to see if it'll peer with you, since it'll probably be about as close as you can get network wise.

It thinks that the provided server is inacurate (the machine's internal clock is more acurate). Leave it running a couple of days and then see what happens. The whole idea is to calculate the drift of the machines internal clock. NTP will not trust specified timeservers blindly. Frankly I think that ntp works best with several timeservers.

No, but do I have to do this manually? It seems ntp can discover the stratum of the servers by itself. I have put all the servers I was using in my local server in one workstation, and am monitoring it now. It seems it's always picking one of them as peer, though it varies a lot. -- Bruno Lustosa, aka Lofofora | Email: [EMAIL PROTECTED] Network Administrator/Web Programmer | ICQ: 1406477 Rio de Janeiro - Brazil | -- gentoo-user@gentoo.org mailing list

I'm not the best man to advise on ntp (because I don't use it), but that's what I remember being recommended by a developer in the forums. May be you want to do a quick search there on time synchro or something like that. -- Regards, Mick Lycos email has now 300 Megabytes of free storage... Get it now at mail.lycos.co.uk
