Kresd: local PTR addresses not resolved

[dr4Ke]

Hi,
I’m using the latest stable release of TurrisOS on a TurrisMOX device.

I’ve put some local hosts in the DHCP static leases and some additional addresses/hosts in the hosts list.

All local hosts are correctly resolved but I can’t get the reverse entries.

Reverse:

$ dig -x 192.168.10.1 @192.168.10.1

Is this expected?

My kresd.config file:

--Automatically generated file; DO NOT EDIT
modules = {
    'hints > iterate'
  , 'policy'
  , 'stats'
  , predict = {
        window = 30 -- 30 minutes sampling window
      , period = 24*(60/30) -- track last 24 hours
  }
}
hints.use_nodata(true)
hints.config('/tmp/kresd/hints.tmp')
trust_anchors.remove('.')
trust_anchors.add_file('/etc/root.keys', true)
net.bufsize(1232)
net.ipv4=true
net.ipv6=true
cache.open(20*MB)
table.insert(policy.special_names, { count = 0, cb = policy.all(
policy.TLS_FORWARD(
{{'9.9.9.9'
,hostname='dns.quad9.net'
,ca_file='/etc/ssl/certs/ca-certificates.crt'
},{'149.112.112.112'
,hostname='dns.quad9.net'
,ca_file='/etc/ssl/certs/ca-certificates.crt'
},{'2620:fe::fe'
,hostname='dns.quad9.net'
,ca_file='/etc/ssl/certs/ca-certificates.crt'
},{'2620:fe::9'
,hostname='dns.quad9.net'
,ca_file='/etc/ssl/certs/ca-certificates.crt'
}}))})

The /tmp/kresd/hints.tmp file contains lines like those:

192.168.1.1 box.maison.dr4ke.net
192.168.10.1 turris.maison.dr4ke.net
fdd1:1558:7154:9::1 turris.maison.dr4ke.net
