Does it work if you issue with ntp daemon off :
If it works command should return data indicated that time was synced.
You can run it multiple times if you want.
Can you check your NTP conf on the client (that box) ?
Does netstat or lsof show what is holding the port open ?
Perhaps your HPUX box is configured as NTP server with some other (copied) /etc/ntp.conf config file and directives in it to bind to non existing address ?
If your server is NTP client (wants to sync time from your NTP servers), all you should have is couple of lines in ntp.conf (with additional steps you did correctly - netdaemons etc) for things to work (with resolving working or hosts/resolv.conf file configured).
I've been tasked to implement ntp on my SCO Unix servers. I have over 600 servers spread across the US in different time zones. Each remote server has network connectivity to a main server here, through their local ISP. (That's how we currently deliver mail to them).
My question is, how can... (5 Replies)

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...

Hy,
I'm having problems with NTP synchronisation on one of the machines wich runs SCO 5.0.5Eb.
It should synchronize with one RedHat machine in local network, but it doesn't (all other machines are fine). It just falls behind after a while.
In /etc/ntp.conf i have only this entry:

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)

Hello,
one of my clients has the following task for me:
To write a Perl script that checks, whether ntp is active on a particular AIX or Linux box.
Obviously the last synchronization is logged in the file ntp.log
So, my task would be find out, when the synchronization SHOULD have taken... (1 Reply)

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.
