THanks for the huge and quick response! attached are some of the responses,
sorry, too many responses to list them all.

I stand corrected - NTP is the correct name (NNTP is Network News Transfer Protocol)

Everyone suggested www.ntp.org for more information

Solaris 2.6 and later comes with it (called TIME service or xntp !)

thanks!

NNTP is a news server. Ntp or xntp are time servers. Solaris 2.6 and later
come with xntp. Just set up /etc/inet/ntp.conf and then run
        /etc/rc2.d/S74xntpd start
and check /var/adm/messages for errors. Once you have xntp working, it
will restart at the next boot.

For Cisco boxes, you can use the ntp config command to point them at one
of you local systems which is getting its time from a master clock. Windows
systems can use "About Time" from
        http://www.arachnoid.com/abouttime/index.html

If you have Solaris 2.5.1 or earlier, you can use xntp 3.4, which I got
some time back. To quote the README: "This distribution is normally
available by anonymous ftp as the compressed tar archive
xntp-<version>.tar.Z in the pub/ntp directory on louie.udel.edu."

NNTP is a news transfer protocol. NTP is the time server protocol.

www.ntp.org

Although most UNIX versions (including Solaris 2.6 and higher) come with
some version of it already in the OS. You just have to configure it.
Older versions were called xntpd.

comp.protocols.time.ntp is a good newsgroup for NTP issues.

cd /etc/inet

edit the ntp.server file as you like and cp it to ntp.conf

it starts automatically from rc2 if ntp.conf exists

For which Unix? Solaris 6, and later, come standard with NTP, as does HP-UX 10.x and later. Those are the only two Unices I'm familiar with. For any of the rest, you can build the daemon from source.

> (to synchronize non-Sun devices such as PCs, Cisco routers & switches, etc;

For PC's, that depends on the OS. For NT4, there's "timeserv" in the NT Resource Kit. For Windows 95, there's a freeware product called Dimension 4 that works quite well, but it's a bitch to deinstall.

For Cisco I can't help.

> for Suns, we have RDATE)

You either have, or can get, NTP as well.

I use ntp to sync off of ntp.home.net and/or clepsydra.dec.com and then use ntpdate (part of ntp) or rdate to sync of my local time server. I found ntp to flakey to use on all my systems

Hi Edward,

As NNTP is Network News Transfer Protocol, I assume you mean NTP, the Network Time Protocol :-)
