Full Discussion: ntp.conf vs. step-tickers
Operating Systems Linux Red Hat ntp.conf vs. step-tickers Post 302459832 by Neo on Tuesday 5th of October 2010 12:45:58 PM

You should have a step-tickers file in all servers that are running ntpd. This is the file that is used by ntpd to call ntpdate and set the correct time when the daemon starts up.

What happens? The startup script in /etc/rc.d/init.d/ntpd will read the servers in the step-tickers file and execute the ntpdate command as follows:

Code:
 /usr/sbin/ntpdate -s -b -p 8 your.time.server.in.step.tickers

For example, if the time of the hardware clock is way off, it is possible that ntpd will not start.

DCONTROL(1)                                                                                                                            DCONTROL(1)

NAME
dcontrol -- Query package and source control files for all Debian distributions SYNOPSIS
dcontrol [options] package[modifiers] [...] DESCRIPTION
dcontrol queries a remote database of Debian binary and source package control files. It can be thought of as an apt-cache webservice that also operates for distributions and architectures different from the local machine. MODIFIERS
Like apt-cache, packages can be suffixed by modifiers: =version Exact version match @architecture Query this only architecture. Use @source for source packages, @binary excludes source packages. /[archive:][suite][/component] Restrict to archive (debian, debian-backports, debian-security, debian-volatile), suite (always codenames, with the exception of experimental), and/or component (main, updates/main, ...). Use two slashes (//) to separate suite and component if the suite name contains slashes. (Component can be left empty.) By default, all versions, suites, and architectures are queried. Refer to http://qa.debian.org/cgi-bin/dcontrol for currently supported values. OPTIONS
-s, --show-suites Add headers showing which distribution the control file is from. -d, --debug Print URL queried. -h, --help Show a help message. -V, --version Show version information. CONFIGURATION VARIABLES
The two configuration files /etc/devscripts.conf and ~/.devscripts are sourced by a shell in that order to set configuration variables. Command line options can be used to override configuration file settings. Environment variable settings are ignored for this purpose. The currently recognised variable is: DCONTROL_URL URL to query. Default is http://qa.debian.org/cgi-bin/dcontrol. AUTHOR
