no server suitable for synchronization found In new HP-UX server

Hi Gurus

I did a new installation (HP-UX) and when i try to activate NTP server, the response is "no server suitable for synchronization found"

I did the configuration manually using the following procedure

*.- /sbin/init.d/xntpd stop
*.- Edit the /etc/rc.config.d/netdaemons file

export NTPDATE_SERVER="172.16.50.41 172.16.50.42"
export XNTPD=1
export XNTPD_ARGS=

*.- Edit the /etc/ntp.conf file
Add the following lines
server 172.16.50.41 prefer
server 172.16.50.42

*.-/sbin/init.d/xntpd start
after that i saw the message "no server suitable for synchronization found"

i did the following command
------------------------------------------
cg4:/usr/sbin #/usr/sbin/ntpdate -d 172.16.50.41
transmit(172.16.50.41)
transmit(172.16.50.41)

Re: no server suitable for synchronization found In new HP-UX server

Yopu have done everything correctly -- it's not an HP-UX problems. Neither of those IP addresses is working as an NTP server. The reasons could be:

- The IP addresses are unreachable (not on same network and no route is available). Use traceroute 172.16.50.41 and traceroute 172.16.50.42 -- if traceroute fails, contact your network administrator.

- The server will not allow your system's IP address to obtain NTP information. Contact the NTP server administrator to allow your IP address to poll the server.

- Someone gave you the wrong IP addresses for the NTP servers.

- Port 123 is blocked between your HP-UX server and the NTP servers. Contact your network administrator.

Re: no server suitable for synchronization found In new HP-UX server

You should also add at least a third time source to allow NTP to have some hope of detecting bad time sources.
