Update broke mailinabox

Help with Setup/Upgrade

That explains why my machine broke after initially working.

I now had to add some lines (with customized paths in comparison to the source link) to /etc/nsd/nsd.conf to get it working again in my IPv4-only environment:

server:
  hide-version: yes

  # identify the server (CH TXT ID.SERVER entry).
  identity: ""

  # The directory for zonefile: files.
  zonesdir: "/etc/nsd/zones"
  ip-address: <<YOUR PUBLIC IP>>
  # ip-address: ::1 # note the manually disabled IPv6

remote-control:
  control-interface: 127.0.0.1

    # nsd server key file for remote control.
  server-key-file: "/etc/nsd/nsd_server.key"

    # nsd server certificate file for remote control.
  server-cert-file: "/etc/nsd/nsd_server.pem"

    # nsd-control key file.
  control-key-file: "/etc/nsd/nsd_control.key"

    # nsd-control certificate file.
  control-cert-file: "/etc/nsd/nsd_control.pem"

How can I make this change permanent?

I don’t know if

helped to solve

I also propose to give this thread a more meaningful title in relation to nsd.
