time synchronisation - how?

[Kathy Donnelly]

What is the equivalent of rdate on HP-UX?

Thanks in advance
Kathy

There is no support for rdate on HP-UX, nor is there an exact equivalent.
What you can use is the NTP utilities supplied with HP-UX as of HP-UX 10.x.
man xntpd

Also SAM will allow you to set this up on your HP-UX systems.

Hi,

If you want to implement time sync for your systems you will need to use NTP.
The set up and running is really quite simple.

The files you will need to set are

/etc/rc.config.d/netdaemons
/etc/ntp.conf

I provided a url reference so that you can review what servers are available to
use free. I spent a little bit of time reviewing the list and selecting stables
environments. If there is a firewall at your office you will require a rule
permitting port 123/udp to go out from where you define.

It would be best if you set up two servers to go out and sync time. Then point
the remainder of the servers to the two servers you have polling. When you are
testing if the ntp is working I used ntpdate -d IP address.

Good Luck

Hi Kathy,
have the same problem;
network with radio controll clock; rdate running on DEC-ULTRIX, not running on HP-UX.
(How) did you solve the problem? (you gave no points!)
thanks for your answer (if you should read this message anymore)

As mentioned, there is no direct equivalent of rdate.
But if you're looking at a one-off time adjustement, maybe "date -a" will help?

Once you have a stratum time server to sync with, use ntpdate -s where is the stratum time server you wish to sync with.
