Hi nochmal,

ich glaube wirklich nicht, dass ich das aktiv war, sondern dass ds irgendwas mit dem Update zu tun hatte, aber was solls. Ich habe diese Anleitung gefunden ([https://www.linuxuprising.com/2020/07/ubuntu-how-to-free-up-port-53-used-by.html](https://www.linuxuprising.com/2020/07/ubuntu-how-to-free-up-port-53-used-by.html)), und mich dran gehalten. Testen kann ichs an den Clients erst morgen, aber der Status von Samba sieht schonmal anders aus:

```auto

```

und auch das mit den Ports gleicht nun dem von Holger:

```auto
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
samba 16260 root 36u IPv6 50934 0t0 TCP *:domain (LISTEN)
samba 16260 root 38u IPv6 50935 0t0 UDP *:domain 
samba 16260 root 39u IPv4 50936 0t0 TCP *:domain (LISTEN)
samba 16260 root 40u IPv4 50937 0t0 UDP *:domain 
```

Hier nochmal in Kurz, was ich getan habe: `/etc/systemd/resolved.conf` abgeändert zu:

```auto

DNS=10.0.0.1
#FallbackDNS=
#Domains=
#LLMNR=no
#MulticastDNS=no
#DNSSEC=no
#Cache=yes
DNSStubListener=no
```

Den Symbolic-Link angelegt wie beschrieben (und vorsichtshalber ne Kopie von /etc/resolv.conf gemacht):

```auto
sudo ln -sf /run/systemd/resolve/resolv.conf /etc/resolv.conf
```

Und den Server neu gestartet. Ich hoffe mal morgen - bzw. heute - tuts. Sobald ich das weiß ergänz ich das hier noch.

Gute Nacht 🙂
