All here, thank you for listening. Now I've set up a Linux NTP server by adding a external windows NTP server in /etc/ntp.conf. Then I start the ntpd daemon. But how often does the Linux NTP server update its time with the external NTP server? I've looked up everywhere but found no information... (1 Reply)

Ok, I have 4 production systems. There is one NTP server for all four systems. In each system there is one Solaris 10 box that points to that NTP server. All of the other machines in the system point to the Solaris 10 machine to get their time sync.

NAME
ntptrace - trace a chain of NTP servers back to the primary source
SYNOPSIS
ntptrace [ -vdn ] [ -r retries ] [ -t timeout ] [ server ]
DESCRIPTION
ntptrace determines where a given Network Time Protocol (NTP) server gets its time from, and follows the chain of NTP servers back to
their master time source. If given no arguments, it starts with localhost . Here is an example of the output from ntptrace :
% ntptrace localhost: stratum 4, offset 0.0019529, synch distance 0.144135 server2ozo.com: stratum 2, offset 0.0124263, synch distance
0.115784 usndh.edu: stratum 1, offset 0.0019298, synch distance 0.011993, refid On each line, the fields are (left to right): the host
name, the host stratum, the time offset between that host and the local host (as measured by ntptrace ; this is why it is not always zero
for " localhost "), the host synchronization distance, and (only for stratum-1 servers) the reference clock ID. All times are given in sec-
onds. Note that the stratum is the server hop count to the primary source, while the synchronization distance is the estimated error rela-
tive to the primary source. These terms are precisely defined in RFC-1305.
OPTIONS
-d Turns on some debugging output.
-n Turns off the printing of host names; instead, host IP addresses are given. This may be useful if a nameserver is down.
-r retries Sets the number of retransmission attempts for each host (default = 5).
-t timeout Sets the retransmission timeout (in seconds) (default = 2).
-v Prints verbose information about the NTP servers.
BUGS
This program makes no attempt to improve accuracy by doing multiple samples.
