How can i configure a NTP Server with OpenVms 7.3-2

[berlioz]

Hello,
i'm actually looking for the best way to synchronise system time for my network (TCP/IP network, 5 Alpha DS25 server With OpenVms 7.3-2, 5 vax that i can synchronise through my application).

Is this possible with NTP Server ? Is there a list of recommended materials ? (gorgy timing NTP LEDI NETWORK for example)

What's the difference between DTSS and NTP synchronisation ?

Is there a procedure for NTP configuration in OpenVms Doc ?

Thanks for all

philippe

Which IP software? DEC/Compaq/HP TCPIP?

Different software. DTSS uses DECnet, and
NTP uses IP, so NTP is more popular on
non-VMS systems.

SYS$COMMON:[SYSHLP.EXAMPLES.DTSS] has a
program which allows one to synchronize a
local DTSS server with an (external) NTP
server. Handy if you're already using DTSS.

NTP is a TCPIP/IP thing, while DTSS is the DECnet counterpart, I would stay with NTP.
You configure NTP with SYS$MANAGER:TCPIP$CONFIG (menu 3 - server). Then you enter your timeservers into TCPIP$NTP.CONF, found in the login directory of the TCPIP$NTP user, theres is a template as s starter.

If you have a connection to the internet you may use e.g. (that's my setup at home):

server 0.pool.ntp.org
server 1.pool.ntp.org
server 2.pool.ntp.org

Here's a docu I wrote a couple years ago to help some of our internal support folks configure systems using NTP at various sites. This includes the initial setup, config file setup, verification of setup, troubleshooting tools, and several references.

HTH,

According to TCP/IP doc there's many version of NTP protocol.
I'm currently managing a private network without any internet access so i've to buy and install my own NTP server.
is there a list of recommended materials ? or unrecommended for openvms ? a list of models already experienced ?

What are you planning to use as your master
clock?

Most people (I assume) use some time
server(s) on the Internet.

my own NTP server (like Gorgy timing NTP LEDI NETWORK SE for example or BODET model - i'm french) with radio antenna

[Steven Schweda]

Ah. Ok, Google found a Web page for it.

In general, any NTP server should work, and
synchronization with the German VLF radio
station should be fine.

I don't know if any VMS NTP software can deal
with the Gorgy Timing authentication stuff.
You should probably ask them if that's
optional or required.
