HP-UX

Thanks peasnat.

I have configured netdaemons config file.

However NTPDATE_SERVER address have the address of primary time server only.

Code:

 
/etc/ntp.conf file
server SERVER_A prefer
server SERVER_B
 
netdaemons file
export NTPDATE_SERVER=SERVER_A
export XNTPD=1

Now say SERVER_A goes down and xntpd uses SERVER_B for time synchronization then I need to manually change the netdaemons file and update the NTPDATE_SERVER=SERVER_B.

Please confirm above understanding.

Hi Sai,

need some details :-

1. Are u making two NTP server, using those clients will sync.
2. If you are configuring NTP client only, the ur configuration is right now. u just need to run /sbin/init.d/xntpd stop and the start. ur client will sync everytime to available NTP server. (no manual intervention needed)
3. after this run ntpq -np (after 3 -4 min). ur NTP client will be sync.

Hi Amit,

Thanks for the reply.

Yes I want to make two ntp servers using which clients will sync, main purpose here is if one of the ntp server fails,client should automatically sync using another server.

I can confirm that placing space separated values work (machines boots and gets the proper time )

This was done on HPVM host HPUX v2, with SERVER_A alive and this setup :

Code:

export NTPDATE_SERVER="SERVER_A SERVER_B"

Now i can't test if SERVER_A is not alive, but i belive it should work.

Thanks Peasnt!!!

I will configure the netdaemons file accordingly.

Will post the configurations and findings after testing it.

Hi Experts,

I configured ntp as below, and it is working fine now.

Code:

 
/etc/ntp.conf
server server1 minpoll 1 prefer
server server2 minpoll 1
driftfile /etc/ntp.drift
 
netdaemons
export NTPDATE_SERVER="server1 server2"
export XNTPD=1
export XNTPD_ARGS=

Thank you so much your help.
