What is the best way to keep the system clock synchronized? I have looked at ntp and netdate. Is one good over the other? Basically I want to know if what is the most secure way to keep the system clock insync. netdate will require me to open up some port 37... is this safe? ntp also... (1 Reply)
i have an HP UNIX box w/c acts as ntp server... I tried to change the time plus 8 minutes... the problem is that the other HP UNIX ntp client did not follow the time... when I tried to restart ntp client... using stop start it only sync to the server once... when I issue the command "ntpq -p", w/c...

Hi Friends,
I want a shell script which will move certain .jar files from a specified location (say /publish/content) to (/publish/archive) on every saturday morning 6 am.
One more thing to add is that before moving files it must check free space at (/publish/archive), if it is more than 60 %... (7 Replies)
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)
hello all,,
am trying to do a time synchronization between a ntp server and a client, but facing some problems in doing so:
i run the ntpdate in debug mode and this is what i got. please help me out..

Good morning,
My first post and first visit, so hello. I have been asked to see if one of our Linux boxes can have it's time sync automatically because the person who built the system has told our staff it cannot be done. To me that raised some flags because although I am no Linux expert, I just... (12 Replies)

Dear All,
Today, somewhere around 7:30 GMT (2:30 PM Eastern Time) www.unix.com will go down for what we hope is around 15 - 20 minutes as we change out some hardware on the server.
Thank you for your patience and support.

There is one server in my company where the time is out of sync.
When I checked (compared with other servers whose time is correct), the XNTPD variable in /etc/rc.config.d/netdaemons was set as 0.
I changed this to 1, and tried restarting the xntpd process with :
# /sbin/init.d/xntpd start

ntptrace
ntptrace(1) General Commands Manual ntptrace(1)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.
