Hi,
Iam facing issues with ntp broadcast ip address in case of IPv6.
Iam using the latest ntp 4.26p3 package.
Can I have a use case scenario for ntp broadcast in IPv6?
As I see in the documentation, we can have only multicast
addresses in IPv6.
Where did you see that? It's not true, multicast also works with IPv4.
*/RV: Iam not saying multicast does not work with IPv4. I was saying for
IPv6, we can give only multicast addresses as part of broadcast command. /*
That is correct. There is no such thing as broadcast in IPv6.
Here are my configurations:
Client side:
*# Created by IMI. /etc/ntp.conf*
*authenticate yes*
*
What is this? I don't recall such an option.
*/RV: This is to enable authentication./* */However in my case, I was
trying without authentication. /*
You don't enable or disable authentication with such an option as it
doesn't exist. The corect option is enable/disable auth
*
*# Broadcastclient mode. *
*disable auth *
*#broadcastclient*
*
*
*multicastclient ff02::101*
*
*
*# Drift file*
*driftfile /etc/ntp/drift*
*
*
*# Keys file. *
*keys /etc/ntp/keys*
*#trustedkey 100*
Server Side:
*# Created by IMI. /etc/ntp.conf*
*server 127.127.1.0 #Local clock*
*fudge 127.127.1.0 stratum 2 #Not disciplined*
*
*
*broadcast ff02::101 iburst*
iburst is invalid.
*/RV: Yes, It is invalid, because it doesn't send burst of packets in
case of broadcast. It was a misconfiguration./*
*#authenticate yes*
*
*
*# Drift file*
*driftfile /etc/ntp/drift*
*
*
*# Keys file. *
*keys /etc/ntp/keys*
*#trustedkey 100*
Iam able to see the broadcast packets being received in the client
but time
synchronization does not happen in the client.
I have even enabled the authentication on both the sides also. But
no use.
Can somebody help me out from this?
run ntpd -D2 and see what the output looks like.
*/RV: I couldn't run the ntpd with -D2 option as it is not available./*
*/These are the options available for ntpd (alphabetically)/*
/-b no bcastsync Allow us to sync to broadcast servers/
/-c Str configfile configuration file name/
/-f Str driftfile frequency drift file name/
I don't know where you are getting these options. That's a very small
subset of the options. If you do not have debug enabled when compiling
you won't get the -D or -d options.
