Description

Somehow ntpd sets stratum 16 number if one selects to listen on multiple interfaces
and virtual IPs. If it only listens on LAN for example then it works and sets proper stratum number.

Scenario when two interfaces are selected: LAN and em5 10.27.88.1

I don't think there's a general issue here. There are tons of systems out there that run ntpd selected on multiple interfaces.

If you have a specific, repeatable scenario where that occurs, please provide details.

What specific details do you need?

I'm having the same issue again. 

2.1.2-RELEASE (i386) 
built on Thu Apr 10 05:23:34 EDT 2014 
FreeBSD 8.3-RELEASE-p15

With ntpd listening on multiple interfaces:

[2.1.2-RELEASE][root@example.org]/root(3): ntpq -c peers 127.0.0.1
     remote           refid      st t when poll reach   delay   offset  jitter

As soon as I switch to listening on one interface only I get:

2.1.2 is something you should not use, let alone report bugs about it.

I use it because it has stable IPSEC. Racoon.
When my issues with strongswan disappear I'll switch.

Updated by Eduard Rozenberg about 10 years ago

Same issue here with 2.2.5 in 2 firewall CARP scenario.

Both firewalls set to listen to 2 interfaces: LAN and LAN CARP.

Only Firewall 2 has a problem:

Firewall 1: Sync Source 198.60.22.240 (stratum 1, .GPS.)
Firewall 2: Sync Source No active peers available

Same problem at our two sites which have a 2 firewall CARP setup.
