Nach Serverupdate AD-Server-Connection fehlt

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), und mich dran gehalten. Testen kann ichs an den Clients erst morgen, aber der Status von Samba sieht schonmal anders aus:

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

COMMAND   PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
samba   16260 root   36u  IPv6  50934      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:

DNS=10.0.0.1
#FallbackDNS=
#Domains=
#LLMNR=no
#MulticastDNS=no

DNSStubListener=no

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

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 :slight_smile:
