Hi,
I think you should use --domain local parameter. It will tell your clients to
use common dns domain and would resolve such names in dnsmasq.
Where are your DNS data stored? Do you use /etc/hosts for them? Do you have
there fqdn with unqualified aliases?

I am new maintainer of dnsmasq package in RHEL. I am looking for potential

The first problem is, manual page is not updated. It tells you cannot

Hi!
Some guys using dnsmasq in virtual machines and OpenStack use custom
dhcp_script to manage leases of clients.
However they complain if there is anything wrong with them, then are just told
broken pipe and no information.
We understand it should not produce any output under normal operation.

Hi Nathan.
If you hit a cache limit of 1 quite often, are you sure dnsmasq is still
the best choice for that server? I think dnsmasq focuses on small home routers
and end networks. Have you considered other caching resolver, unbound for
example? I think if this limit is not enough, maybe yo
remaining bugs are mine, but Petr please check that I didn't break
things.
Cheers,
Simon.

Hi Tony,
I think dhcp-script can be used to log any information related to dhcp
assignments in custom format. I think basic dhcp request informations is
logged even without log-dhcp. Have you checked syslog or journalctl?

it is kind of possible. But usually there is another way to solve your

Hi!
I was playing a bit with auth-vm and auth-server together with virtual
machine manager. I think it might be useful to omit interface in
auth-server at all, just change name reported by auth-vm zones on normal
dns port.
Libvirt uses dnsmasq as DHCP and DNS server on each virtual network
config
I think tools from contrib/lease-tools might help you with that. It
makes dnsmasq to release some lease on demand. If you shut down VM, it
can be used to free its former lease.
I think also d-bus API can be used for the same thing, it might be more
reliable.

Never tried it myself, but if you synchronize configuration from primary
to secondary server, it might work somehow together.
Consider setting dhcp-authoritative on primary instance, but make sure
it is not there on secondary. You may want to use different dhcp-range,
so dynamically allocated host

If one interface stops listening, do not stop listening yet until all
listeners end.
Because address includes family, patch 5 removes duplicate family. Made
that separate because it kind of cover what is important change.

and, maybe it should print complete address with port as
well. Precise information does not hurt, even when port would be a bit
repeating. Now it includes also port. These are just debug information
after all, no need for them to be shortest possible.

Hi Martin,
I think it would make more sense to not derive intended behaviour from
number of interfaces but allow desired behaviour to be specified explicitly.
If machines want to reuse the same address multiple times on different
interfaces, they may want explicit configuration of BINDTODEVICE

Hi John,
unless you want too much work, I would suggest using separate domain for
management names. If you are not afraid management network would be
accessible to all users, just use --server=/mgmt.example.net/1.2.3.4 and
--server=5.6.7.8 for normal names (or just read /etc/resolv.conf for
them).

Hi John,
we are using kind of hack for similar purpose in dnssec-trigger package.
If udhcpc serves domain or search directives for resolv.conf, they can
be used to redirect just those domains to management servers. It can
work centrally managed. But requires special handling of search domains,

Hi John,
dnsmasq is quite interesting piece of software. It is used by lot
different kind of projects. I think noone objected dnsmasq isn't useful
or Simon does not work on it.
But as with everything, there is always some space for improvements.
