User have to do below changes in client ntp.conf file for receiving ntp broadcast packets.
# disable auth
keys /etc/ntp/ntp.keys # symmetric key file
trustedkey 1 2 8 10
# total trusted keys list
broadcastclient key 8 # 8 is key id number required from trusted keys
broadcastdelay 0.01
3. For Broadcast with Autokey authentication :
User have to do below changes in client ntp.conf file for receiving ntp broadcast packets.
# disable auth
crypto pw password
#Autokey
keysdir /etc/ntp
# public keys directory path
crypto randfile /dev/urandom
broadcastclient autokey
broadcastdelay 0.01
4. For multicast without authentication :
User have to do below changes in client ntp.conf file for receiving ntp broadcast packets.
disable auth
multicastclient
224.0.1.1
multicastclient ff08::101
This command enables reception of multicast server messages to the multicast group address(es)
(type
m
) specified. Upon receiving a message for the first time, the multicast client measures the nominal
server propagation delay using a brief client/server exchange with the server, then enters the broadcast
client mode, in which it synchronizes to succeeding multicast messages. Note that, in order to avoid
accidental or malicious disruption in this mode, both the server and client should operate using symmetric
key or public key authentication
5. For multicast with symmetic key authentication :
User have to do below changes in client ntp.conf file for receiving ntp broadcast packets.
# disable auth
keys /etc/ntp/ntp.keys # symmetric key file
trustedkey 1 2 8 10
# total trusted keys list
multicastclient
224.0.1.1 key 8 # 8 is key id number required from trusted keys
multicastclient
ff08::101 key 8 # 8 is key id number required from trusted keys and ff08::101 is NTP
#multicast address
6. For multicast with Autokey authentication :
