Having servers in production is not a good reason to run insecure code when you could be running much more secure code that works the same or better.
Also, based on my experience, there are no issues cutting over to chrony from ntpd, especially if your version of ntp is keeping time correctly, and even if it was not, chrony is designed to slowly bring system time into compliance.
Hi Friends,
How can I Restore the Files present under "lost+found" Directory of a FileSystem (in Solaris & Tru64 OS) to their original Locations.
Now-a-days I am loosing lots of files in 2 of my Machines,
One running Solaris8 and other Tru64(Digital) Unix.
Thanx in... (1 Reply)
Is there some way to force the NTP server on a brand-new install to be "suitable" to sync other servers from? (I'm more concerned with synchronization between machines, and less concerned with what the actual time they sync to is)
For example, whenever I install fresh from the Fedora DVDs and... (0 Replies)
does anyone know how to change the treshold of 128ms in NTP.
in order to ignore these alarms:

Hi,
I was trying to call "script <an ip add>" command from .profile file to log everything whenever anyone logs in to this user. I did the following at the end of .profile. 1) Extracted the IP address who logged in 2) Called script < ip add> . The problem I am facing is all, aliases etc. written... (3 Replies)
Hi,
This is odd, however here goes. There are several shell scripts that run in our production environment AIX 595 LPAR m/c, which has sufficient memory 14GB (physical memory) and horsepower 5CPUs. However from time to time we get the following errors in these shell scripts. The time when these... (11 Replies)

Hi All,
I'm completely new to bash scripting and still learning my way through albeit vey slowly.
I need to know where to insert my server names', my ip address numbers through out the script alas to no avail.
I'm also searching on how to save .sh (bash shell) script properly.... (25 Replies)

CHRONY(1) User's Manual CHRONY(1)NAME
chrony - programs for keeping computer clocks accurate
SYNOPSIS
chronyc [OPTIONS]
chronyd [OPTIONS]
DESCRIPTION
chrony is a pair of programs for keeping computer clocks accurate. chronyd is a background (daemon) program and chronyc is a command-line
interface to it. Time reference sources for chronyd can be RFC1305 NTP servers, human (via keyboard and chronyc), or the computer's real-
time clock at boot time (Linux only). chronyd can determine the rate at which the computer gains or loses time and compensate for it while
no external reference is present. Its use of NTP servers can be switched on and off (through chronyc) to support computers with dial-
up/intermittent access to the Internet, and it can also act as an RFC1305-compatible NTP server.
USAGE
chronyc is a command-line interface program which can be used to monitor chronyd's performance and to change various operating parameters
whilst it is running.
chronyd's main function is to obtain measurements of the true (UTC) time from one of several sources, and correct the system clock accord-
ingly. It also works out the rate at which the system clock gains or loses time and uses this information to keep it accurate between mea-
surements from the reference.
The reference time can be derived from either Network Time Protocol (NTP) servers, reference clocks, or wristwatch-and-keyboard (via
chronyc). The main source of information about the Network Time Protocol is http://www.eecis.udel.edu/~ntp.
It is designed so that it can work on computers which only have intermittent access to reference sources, for example computers which use a
dial-up account to access the Internet. Of course, it will work on computers with permanent connections too.
In addition, for Linux 2.0.x (for x >= 32) or 2.2 onwards, chronyd can monitor the system's real time clock performance, so the system can
maintain accurate time even across reboots.
Typical accuracies available between 2 machines are
On an ethernet LAN : 100-200 microseconds, often much better On a V32bis dial-up modem connection : 10's of milliseconds (from one session
to the next)
With a good reference clock the accuracy can reach one microsecond.
chronyd can also operate as an RFC1305-compatible NTP server and peer.
