How to setup a Host Override

[johnpoz]

@jimfreeze well you got something a bit wonky there.. the hostname of pfsense should resolve to its LAN ip..

example.

Get rid of your allow wan dhcp to set dns in your general setup.. looks like your asking 192.168.1.254 for dns as well?

[jimfreeze]

@johnpoz As far as I can tell, pfsense is getting the 192.168.1.254 resolver when it gets its address via DHCP from the ATT modem.

I have unchecked "Allow DNS server list to be overridden by DHCP/PPP on WAN" from the general setup.

Still getting a failure on DNS lookup.

[johnpoz]

@jimfreeze well is unbound even running? Pfsense name would what it resolves too out of the box..

[jimfreeze]

@johnpoz I don't think unbound is running.

I went ahead and set up a Host Override for that domain.

Thank you for all the help.

@jimfreeze said in How to setup a Host Override:

I don't think unbound is running.

Then host overrides wouldn't be working either..

Do you have unbound listening on localhost? or All?

[jimfreeze]

@johnpoz I'm not seeing unbound in the web GUI, but it has a process on the box.

unbound 84523   0.0  0.3  65236 28860  -  Ss   14:40      0:00.90 /usr/local/sbin/unbound -c /var/unbound/unbound.conf

[johnpoz]

@jimfreeze go to status services do you see it running?

[jimfreeze]

@johnpoz Ahh, yes, thank you. It is running.

[johnpoz]

@jimfreeze well then it should timeout after 800 some ms.. for pfsense name.. Its right there in the file.. See mine sg4860.local.lan

Again will ask - is it listening on all or if not all atleast has localhost (127.0.0.1) listed

[jimfreeze]

@johnpoz It appears to be listening on all.

Hi, I am not sure but maybe you need to clear your state table.

[jimfreeze]

@uglybrian Hmmm. I reset the state table, and same result.

% ping pfsense.lan
ping: cannot resolve pfsense.lan: Unknown host

[johnpoz]

@jimfreeze why would you think .lan would work, you were using .local or home.arpa

What does your /etc/hosts file have in it?

[jimfreeze]

@johnpoz I haven't added anything to /etc/hosts.

Is home.arpa special in some way?

[Uglybrian]

It’s your host name and domain. So pfsense.home.arpa

[johnpoz]

@jimfreeze home.arpa is the new standard use local domain.

https://datatracker.ietf.org/doc/html/rfc8375
Special-Use Domain 'home.arpa.'

And yes not exactly sure what exact version of pfsense moved to it vs .localdomain.. But from your previous post that is what you showed as your pfsense name and domain.. pfsense.home.arpa

I kept meaning to move to it from my local.lan - but have a lot certs I have created using local.lan in them, and just haven't bothered to switch yet.

I haven't added anything to /etc/hosts.

Please show it like I did - this will show us what pfsense fqdn should be and any host overrides, etc. you have created. I just snipped mine because I have a lot of stuff in there and was just wanting to what my sg4860.local.lan is listed in there from my general page setup.

BTW - are you using pfblocker? And have something odd setup there? But pfsense from the diag host lookup should for sure be able to lookup its own name ;)

[jimfreeze]

@johnpoz Thank you. That's great information.

/etc/hosts looks standard to me.

% cat /etc/hosts
##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1	localhost
255.255.255.255	broadcasthost
::1             localhost

127.0.0.1	local.host

I installed pfblocker a few hours ago. I just did the basic install.

And, it still doesn't seem to be able to find the home.arpa domain.

[johnpoz]

@jimfreeze that doesn't look like pfsense hosts file..

[jimfreeze]

@johnpoz Looking at the link you set, should the domain setting under general setup be home.arpa. and not home.arpa?

[johnpoz]

@jimfreeze dude that is not your pfsense hosts file..
