dsclose commented on CLOUDSTACK-6975:
-------------------------------------
According to CLOUDSTACK-9035:
* Passwords are sent to both master and backup routers.
* But the password server is not running on the backup router.
This suggests that dnsmasq running on the backup router is not an issue
(despite the keepalived notify_backup script disabling the service.) The issue
with password resets is probably better dealt with in CLOUDSTACK-9035.
That allows us to limit the scope of this issue to whether dnsmasq should be
running on the backup router at all.

> Key: CLOUDSTACK-6975
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-6975
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Virtual Router
> Affects Versions: 4.3.0
> Environment: KVM
> Reporter: Magnus Bengtsson
>
> When using a network offering with redundant routers the default setting of
> EnableServiceMonitoring enables monit on the routers.
> "network.router.EnableServiceMonitoring service monitoring in router
> enable/disable option, default true false"
> This causes monit to run dnsmasq on both the Master and Backup router. When
> the backup router assigns dhcp to clients, password and userdata retrieval
> from that node fails since the services are not running on the backup router.
