Re: NTP (not SNTP) on the System i ?

Looks like HMC supports NTP
http://www-01.ibm.com/support/docview.wss?uid=nas8N1015481

I assume there's some way for the HMC to update the IBM i time??

Otherwise...I'd call IBM....I'd hope a government requirement would get you
a solution a little quicker.

There is an existing AIX NTP client...maybe there's some way to use that.

Or perhaps you could port one yourself...

Lastly, have you checked to see if having a NTP client somewhere in your
local net and having the i use SNTP to sync to that would be good enough?

Good Luck!

I need to meet a government requirement that says my System i must use the
NTP protocol and set its time. I'm well aware of IBM's built in support
for
SNTP but the requirements state that SNTP ("simple" network time protocol)
is not sufficient. One of the reasons given is that SNTP allows you to
define multiple time servers on the Internet but it uses a round robin
approach such that if one server is down it goes to the next. With NTP,
apparently multiple servers are considered by the protocol and it
determines
which is the most accurate.



We've tried to demonstrate to the governing body the SNTP support along
with
the log files it creates as it adjusts the time but they've justsaid no so
we're looking for other ways to implement NTP on the System i.



Any suggestions anyone?
