RE: NTP vs SNTP

Drilled down into TCP, Servers and checked SNTP and tried to view Connection Status and it was blank.

Are you talking about the output of netstat *cnn on 5250?

No. See the above steps on how to check it using the webby Navigator for i.

The support person had to look it up and get back to me. Basically it will be blank unless you change your client type from SNTP to NTP. He changed it on his system and then the connection status screen was active.

I guess that SNTP is just a client wether NTP is a full TCP daemon which can also provide other clients with network time service. See https://en.wikipedia.org/wiki/Network_Time_Protocol#SNTP

I am only talking about the SNTP client service, not serving to others. When you set up the SNTP client you can specify if the client is SNTP or NTP. See the webby Navigator for i and check out the properties on the SNTP Client.

It all sounds simple to me until I start worrying about if that will come through different ports, etc on our firewall thus having to get numerous network consultants from different companies involved (DMZ lpar).

I don't get what you want to tell but ntp and sntp is *always* UDP port 123.

Client or server or both?

And if there might be any required modifications on the SNTP servers to support NTP.

There's no such thing as an SNTP server

Are you saying there are only NTP servers and you access those using either a SNTP or a NTP client?

At this time I'm thinking not worth it. What say ye?

What is "it"?

Changing the sntp client from sntp to ntp
