Cannot configure NTP client

Hi, I am trying to configure NTP client on my Solaris server, but I am getting error like:

Jan 13 10:53:33 SPOTS ntpdate[5142]: [ID 831711 daemon.error] no server suitable for synchronization found

My ntp.conf file:

bash-3.00# pwd
/etc/inet
bash-3.00# 
bash-3.00# 
bash-3.00# cat ntp.conf 
# ident "@(#)ntp.client 1.3     00/07/17 SMI"
#
# /etc/inet/ntp.client
#
# An example file that could be copied over to /etc/inet/ntp.conf; it
# provides a configuration for a host that passively waits for a server
# to provide NTP packets on the ntp multicast net.
#

server 10.15.203.70
enable pll

enable auth monitor
driftfile /var/ntp/ntp.drift
statsdir /var/ntp/ntpstats/
filegen peerstats file peerstats type day enable
filegen loopstats file loopstats type day enable
filegen clockstats file clockstats type day enable

keys /etc/inet/ntp.keys
trustedkey 0
requestkey 0
controlkey 0
bash-3.00# 

And when i am do

svcadm enable ntp

i am getting error - no server suitable for synchronization found

Could anyone help me please...

Thanks in advance,

Can you kill ntpdate and xntpd daemons ?

can you ping the ntp server? is the ip correct?

Yes, IP is correct.

to incredible:
Could you please clarify what you mean?

I checked:

bash-3.00# ps -ef | grep xntp    
    root 18069 18054   0 16:14:38 pts/2       0:00 grep xntp
bash-3.00# ps -ef | grep ntpdate
    root 18071 18054   0 16:19:11 pts/2       0:00 grep ntpdate
bash-3.00# 

and:

bash-3.00# svcs -a | grep xntp
bash-3.00# svcs -a | grep ntpdate
bash-3.00# 

ntp is running (or better it is trying to start) on your system. but the given ntp server ISN'T a ntp server or is not reachable:

Jan 13 10:53:33 SPOTS ntpdate[5142]: [ID 831711 daemon.error] no server suitable for synchronization found

Thanks to all for the help!

Finally I could prove to our network admins that problem with FW... since they assert that they have no problems from FW side... And actually - they opened UDP 23 port instead 123... ))))

So, problem is solved now.

Thanks again,
Roman
