fixed delay in a NTP client

[Nacho]

I neet to syncronize some machines (HPUX 10.20) using xntpd with a NTP server, but we need to keep a fixed delay (20 seconds)from the server. Can I do it? Perhaps there is another possibility not using xntpd?

Hi Nacho,

What you could do, for example, is synchronize your systems with the ntp server at regular intervals with 'ntpdate' and immediately after, run a small program which will get the system time, adjust for the delay needed and set the time again. You won't need to have xntpd running on the clients, of course.

See gettimeofday() ans settime() in the manual.

Yoy could also try experimenting by adjusting the 'authdelay' parameter in 'ntpdate' as this could help for small time differences.

See manpage for 'ntpdate'
