[Q] Best location of ntpd driftfile ?
Hi all, setting up ntpd, I find that its default location for the drift file is /etc/ntp.drift. In a way it is part of the configuration an may well belong in /etc, on the other hand I'd rather just have files in /etc which _I_ modify. I would expect the content of ntpd.drift to vary over time, and somehow I would have expected it to belong in the /var part of the hierarchy, but 'man hier' does not offer any serious evidence (should it be /var/db/ntp.dift)? So, what's the canonical way to place this file? (And no, I do _not_ want to know at this time whether anal-retentive is spelt with or without a hyphen. I will post that question in a separate thread as need arises :-) Cheers, Stefan ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

In a way it is part of the configuration an may well belong in /etc, on the other hand I'd rather just have files in /etc which _I_ modify. At one point (15 years ago :-), some people used to modify the contents of ntp.drift by hand. This was for machines which were not connected to a network; by keeping track of the system time drift against an external time reference source over the course of a few weeks, one could compute the right value for ntp.drift and then run ntpd to correct that drift. I would expect the content of ntpd.drift to vary over time, ntp.drift normally converges and stabilizes after a while (a few days to a few weeks), unless the hardware clock is bad. and somehow I would have expected it to belong in the /var part of the hierarchy, but 'man hier' does not offer any serious evidence (should it be /var/db/ntp.dift)? Hmm. Well, ntpd predates the notion of /var, but you could put the drift file under there if you wanted to. I think keeping DNS zone files under /var/named makes a lot more sense than under /etc/named, for instance, but I wouldn't move ntp.drift out of /etc myself. -- -Chuck ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Looks like it's been moved to /var/db/ntpd.drift in FreeBSD-5 ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Now that I'm thinking about this, in particular, moving files which change regularly out of /etc into /var helps one mount root (/) read-only, which is sometimes desirable for embedded appliances and the like which boot off of limited-write media like compact-flash... -- -Chuck ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
