[Samba] Samba and dnsmasq




Hello everyone !

Well, I'm setting up a 'new' box with samba 4.9.3 on Ubuntu 18.04

Idea is to use Host OS for Domain Controler (dc1.smb.domain.tld) and a LXC container (ubuntu 18.04 too) as Domain Member with File Server (fs.smb.domain.tld).

Administration through Windows OS will be done with a Qemu KVM.

Bad thing is that I get :

Failed to bind to 0.0.0.0:53 TCP - NT_STATUS_ADDRESS_ALREADY_ASSOCIATED

as dnsmasq is using port 53 :

netstat -tulpn | grep ":53"
tcp        0      0 192.168.122.1:53 0.0.0.0:*               LISTEN      1283/dnsmasq tcp        0      0 10.0.3.1:53 0.0.0.0:*               LISTEN      1062/dnsmasq tcp6       0      0 :::53 :::*                    LISTEN      1161/samba: task[dn udp        0      0 192.168.122.1:53 0.0.0.0:*                           1283/dnsmasq udp        0      0 10.0.3.1:53 0.0.0.0:*                           1062/dnsmasq udp6       0      0 :::53 :::*                                1161/samba: task[dn
Is there known solutions to resolve this, or should I use this kind of method :
