network time protocol (ntp) help

[Steven Chen_1]

We have a Cisco router that needs to have an ntp to synchronize the network time. Right now our internal emails (behind the router) are using time 4 hours behind EST.

I would like to know if we can have Cisco Router synchronizing the network time with HPUX 10.20. But I could not find ntpd.

Or what methods can I do to have the problem solved?

Thanks a lot.

The ntpd is called xntpd do a man on xntpd for more information.

Use SAM to configure NTP.

[Rick Garland]

Can use SAM or can manually modify the
/etc/ntp.conf file. What is happening is you have at
least one server (prefer two or more) going out to a
stratum 1 server and they sync up. You now have a
stratum 2 time server. All other systems sync to this
stratum 2 server that you have on site.

In the /etc/ntp.conf file, you are defining which servers
to look at for the ntp protocol. SAM is working much
the same way.

There are numerous options with NTP, such as a
driftfile, stats, etc.

There is a previous post from earlier today that discusses this issue

Steven, if you are asking if the CISCO router has the ability to sync to an NTP server, the anser is yes. After you set up the ntp server as stated above, go into the EXEC command set and identify the NTP server(s) to sync to. Use the command:

show ntp status
and
show ntp associations

on your router to verify that the router is successfully syncing to the HP-UX ntp server(s).
