According to
http://support.ntp.org/bin/view/Support/ConfiguringAutokey#Section_6.7.4
the crypto accociation flags can be checked.
I have set up autokey between server and client using IFF keys scheme
ans watching flags on client it shows:
flags=0x87f21 which is using 5 digits after x.
a)
But
According to http://www.ntp.org/ntpfaq/NTP-s-config-adv.htm#S-CONFIG-ADV-AUTH
GQ keys are generated on server using:
cd /etc/ntp
ntp-keygen -T -G -p serverpassword
In the client part of setup it states:
---
GQ Group Keys
Obtain the GQ group key from step 2, copy the key file to the keysdir,
hello all:
according to
http://www.ntp.org/ntpfaq/NTP-s-config-adv.htm#STEP-AUTOKEY-SERVER-GQ
i was able to generate GQ keys on server and copy
parameter file to client:
NOTE: i have used /etc/ntp1; chmod 600 /etc/ntp1 for this purpose
and changed ntp.conf on server and client machines as well.

On a very quiet network, I observe that ntpd sometimes has a very
high loss rate: reach is 6, for example.
When using ping or any other protocol, no packet loss at all is
observed.

It is unclear to me if an outgoing request
would be shown on the trace when ARP resolution is incomplete.
Needing to do ARP will cause some extra round trip delay, but should not
prevent the packet being transmitted. ARP cache timeout is not a
sufficient cause.

On the other hand, I have definitely observed that phenomenon as a

delayed for ARP request and reply at each hop, but the return packet has
no such delay. Quite a while ago I suggested a special

Have you considered the possibility that the computer has an energy saver
NIC,
and NTPD activity is insufficient to wake it?
