Sorry for the late answer. I was away. The same thing I experienced also
today. Now resolvd is behaving as expected. I do not now what changed as
the configuration was the same from my last attempt, when resolvd was keep
adding the ISP DNS.
Thank you all for your time and help!

Re: Dhcp client configuration in 7.0
Hi Benno,
It looks like it is working right now, even after a restart of the router the
extra dns server is not added to
resolv.conf with resolvd enabled and started. The first nameserver
213.75.116.129 entry was added when i enabled
resolvd again, and did not have the "ignore dns" options in place. Then i did
the steps you asked for.
* run "route -n monitor"
* empty the dhcpleased.conf: mv /etc/dhcpleased.conf /etc/X.dhcpleased.conf
* cat /etc/resolv.conf, copy the output into an email.
nameserver 213.75.116.129 # resolvd: vlan4
lookup file bind
nameserver 127.0.0.1
* restart dhcpleased: doas /etc/rc.d/dhcpleased restart
* copy the output of "route -n monitor" into the email
fw# route -n monitor

The "ignore dns" config option causes dhcpleased to send a RTM_PROPOSAL
message to resolvd with an empty DNS proposal for that interface. This
causes resolvd to remove any nameserver entry for that interface from
/etc/resolv.conf.
Note that resolvd adds comments to the lines it touches in resolv.conf, for
example:
nameserver 192.168.1.1 # resolvd: iwm0
Anyone who thinks the "ignore dns" option does not work could help to debug
this with the following:
* run "route -n monitor"
* empty the dhcpleased.conf: mv /etc/dhcpleased.conf /etc/X.dhcpleased.conf
* cat /etc/resolv.conf, copy the output into an email.
* restart dhcpleased: doas /etc/rc.d/dhcpleased restart
* copy the output of "route -n monitor" into the email
* cat /etc/resolv.conf, copy the output into the email.
then run dhcpleased with the configuration file:
* run "route -n monitor"
* mv /etc/X.dhcpleased.conf /etc/dhcpleased.conf
* cat /etc/dhcpleased.conf and copy the output into the email
* cat /etc/resolv.conf, copy the output into the email.
* restart dhcpleased: doas /etc/rc.d/dhcpleased restart
* copy the output of "route -n monitor" into the email
* cat /etc/resolv.conf, copy the output into the email.
send that email as a reply to this thread.

Re: Dhcp client configuration in 7.0
Hi,
Maybe i am wrong and do not understand this right, but wat should the “ignore
dns” option do when used in the dhcpleased .conf config file?
Here @xs4all our IPTV network on a separate vlan also gets an ip address and
the dhcp offer also sends a dns server which should be ignored.
I also thought that with the “ignore dns” option, this dns server was blocked,
but that is not what the option does?

Arnoud

If you never intend to use other nameservers on this system, you can also
deactivate resolvd:
rcctl stop resolvd
rcctl disable resolvd
and remove dhcpleased.conf again.

Yes, at first I was ignoring the curly brackets, but I received no warning
and still got an IP, but after I have seen your configuration I made the
change. Did not help,
The thing is that maybe I do not understand corectly the new way. I thought
that by specifying in dhcpleased.conf that you what to ignore the DNS then
resolvd will leave the resolved.conf untouched. In my case it does not
happen, so I have to just disable resolvd.
Thank you for your time! I will just leave resolvd disabled and resolv.conf
with only 127.0.0.1 in it.

Is that the exact contents of your dhcpleased.conf? Reading the man
page, it seems that the curly brackets are mandatory, and if I change my
config to "interface em0 ignore dns" dhcpleased warns about the syntax
error (and doesn't start).

My dhcpleased.conf is similar (interface urtwn0 ignore dns), but it does
not seem to work. resolvd just overwrites the resolv.conf with the ISP DNS.
If I disable resolvd and I leave only nameserver 127.0.0.1 the unbound
works as expected.
Now, my question is when ignore dns from dhcpleased.conf is considered? The
man page states "Ignore nameservers from leases on this interface" but
maybe I am not reading it correctly?

This works for me:
/etc/hostname.em0:
inet autoconf
/etc/resolv.conf:
nameserver 127.0.0.1
/etc/dhcpleased.conf:
interface em0 {
ignore dns
}

Dhcp client configuration in 7.0
Hello to you all! Prior to 7.0 I was using this line in /etc/dhclient.conf supersede domain-name-servers 127.0.0.1; so that I do not get the DNS from the ISP provider. I am using unbound to resolve my queries. With the new changes I can not get the same functionality. I tried to add this in /etc/dhcpleased.conf interface urtwn0 ignore dns where urtwn0 is my interface or disable resolvd. If resolvd is on I get my ISP DNS server, if not when unbound starts resolvd adds the ISP DNS server to resolv.conf. Can you please tell me what am I doing wrong and how can I have only 127.0.0.1 on the resolv.conf file? Thank you!
