It gets its local dynamic IP correctly assigned by dhcp from the windows server 2008r2. Also, the dns server is assigned correctly (can ping anything inside and outside my local network).

But i cannot ping the raspberry using "raspberry" or "raspberry.xxx.local". Looking into the windows servers dns management, there is not entry for the raspberry in the forward lookup zones.

What am i missing? Im interested in a "plain" solution, if possible without samba or else. Just want the rapsberry to register to the windows dns with its hostname.

Update I (followed the hints from RalfFriedl):

pi@raspberrypi:~ $ nsupdate
> update add raspberrypi.abcb.local 600 a 192.168.12.103
> send
couldn't get address for 'takamaka.abcb.local': not found

pi@raspberrypi:~ $ nslookup takamaka.abcb.local
Server:         192.168.12.10
Address:        192.168.12.10#53

Name:   takamaka.abcb.local
Address: 192.168.12.10

Why can't nsupdate resolve the DNS server IP, but nslookup and host do fine! ping doesn't resolve, too. The dhcp leases:

lease {
  interface "wlan0";
  fixed-address 192.168.12.103;
  option subnet-mask 255.255.255.0;
  option routers 192.168.12.1;
  option dhcp-lease-time 691200;
  option dhcp-message-type 5;
  option domain-name-servers 192.168.12.10;
  option dhcp-server-identifier 192.168.12.10;
  option dhcp-renewal-time 345600;
  option ntp-servers 185.13.148.109,176.9.40.142;
  option dhcp-rebinding-time 604800;
  option domain-name "abcb.local";
  renew 6 2019/02/09 14:18:17;
  rebind 2 2019/02/12 23:39:05;
  expire 3 2019/02/13 23:39:05;
}

    Assuming you installed an RPF Raspbian image on your Pi... the default hostname is raspberrypi BTW: the same is true for the Pi: it's not a Raspberry but a Raspberry Pi. Also never seen 'hostname.xxx.local` I would expect hostname and/or hostname.localto work. The machine you're using this from needs to have avahi/zeroconf/bonjour installed for the .local version to work. – Dirk Feb 5 '19 at 18:33
  • Sorry, my mistake with the hostname. It's raspberrypi. But raspberrypi.localdomain.local is usual for local / active directory domains. As mentioned, i want a "plain" solutions. So avahi/zeroconf/bonjour is not what im looking for, rather what @RalfFriedl suggested below. – JKB Feb 6 '19 at 19:52

Got it, had to remove libnss-mdns with:

rpi ~$ sudo apt-get remove libnss-mdns

I found this solution at nslookup finds ip, but ping doesnt.

As of RFC 6762 the (pseudo) top level domain .local is explicitly reserved for Multicast DNS. As so often Microsoft does not respect such official specifications and uses .local to manage local network segments its own way. Therefore it is known that

The connection of Macintosh and Linux computers or zeroconf peripherals to Windows networks can be problematic if those networks include name servers that use .local as a search domain for internal devices. (ref).

There are many problems known and Microsoft has made some Support article to address this. You can find some hints to avoid the problems by looking at Wikipedia - .local Microsoft recommendations.

If your Windows server allows unauthenticated DNS updates, then a simple update with nsupdate without a key will do. Windows clients also used to send just an unauthenticated DNS update request, and the server would update the DNS entries as requested.

To send a DNS update request, use the nsupdate program:

NAME=raspberry.xxx.local
TTL=60
IP=1.2.3.4
echo "
update delete $NAME A
update add $NAME $TTL A $IP
send" | nsupdate /dev/stdin

Here NAME is the DNS name you want to register, TTL is the time to live in seconds and IP is your IP address.

  • I've tried this. But nsupdate can't resolve the DNS server name, although nslookup can do! What might there be wrong? (Edited the question and added results) – JKB Feb 6 '19 at 20:15
