NTP Unreach/Pending

[meschmesch]

Hello,
NTP is not working, status unreach/pending. The log states

Code: [Select]

unable to bind to wildcard address :: - another process may be running - EXITING

Any idea to solve the problem?
Thx!!!!

issues with IPv6?

take a look at your routing and make sure you are able to ping the NTP servers.

[meschmesch]

Ping is possible. Only v4. I currently have a problem with v6. I request a 61 prefix and assign ID0 ID1 etc, but for whatever reason various interfaces get assigned the same v6 subnet?

Could that be the problem?

How to solve?

[lilsense]

61 is no valid. 64 or 56 should be seleted.

[meschmesch]

The 61 prefix is pre programmed by my internet provider and until some time ago everything worked fine. Was there any change regarding that on Opnsense?

[lilsense]

it's not opnsense.

Hello, the ipv6 issue is solved. IPv6 works flawlessly now. BUT: NTP does not work yet. The protocol says:

try using Chrony package and see if you see the same issue.

[meschmesch]

Chrony works without problems. So? Use Chrony instead??!

[lilsense]

Sure. I do!

[meschmesch]

Can I disable the NTP tool?

Nevertheless it would be interesting to know why it does not work on my machine.

[lilsense]

If you remove all the pools, it will stop ntp service.

[meschmesch]

Works, thank you!

If you use a "pool" directive and "nopeer" at the same time ntpd cannot work.

[meschmesch]

Makes no difference.
