Thank you your configuration file. I'll have to modify my old OI or
upgrade to the latest.

I have trouble with 123 port. I wanted to set a NTP client not a server.
I received an e-mail my ISP with a complain. Someone use my server 123 port.
I'll bounce you the message I sent to this mailing list in February.
It explains how to avoid the NTP amplification exploit that your ISP
complained about.
My NTP settings is the next:
cp /etc/inet/ntp.client /etc/inet/ntp.conf
nano /etc/inet/ntp.conf
Insert these lines. May be the these are not good.
server 0.hu.pool.ntp.org iburst
server 1.hu.pool.ntp.org iburst
server 2.hu.pool.ntp.org iburst
server 3.hu.pool.ntp.org iburst
I don't know what `iburst' means, but `man ntpd' describes it
partially. I don't use it.
svcadm enable ntp
svcs ntp
svcs -x ntp
ntpq -p
How can I solve this problem if I need the NTP client?
Here are the non-comment lines from my ntp.conf:
$ egrep -v '^#|^$' /etc/inet/ntp.conf
restrict default kod nomodify notrap nopeer noquery
restrict 192.168.0.0 mask 255.255.255.0 nomodify notrap nopeer
restrict 127.0.0.1
restrict -6 ::1
server 0.pool.ntp.org
server 1.pool.ntp.org
server 2.pool.ntp.org
server 3.pool.ntp.org
driftfile /var/ntp/ntp.drift
statsdir /var/ntp/ntpstats/
filegen peerstats file peerstats type day enable
filegen loopstats file loopstats type day enable
You likely won't need the `192.168.0.0' line. That's for my private
network.
It works:
$ ntpq -p
remote refid st t when poll reach delay offset jitter
