Enable legacy protocol version (NT1)

[yonz2]

This not really an issue, rather a question:

For a special use case, in a production environment, I need to provide SMB1.0 Services to an IOT device running windows XP.

How can I set the "min protocol" variable to support this?

(Yes, I know about all the security issues, but this will be run on a small server on an isolated network segment)

You can override the command in the compose file and add --option to set min protocol to NT1:

version: "3.5"

services:
  samba:
    image: crazymax/samba
    container_name: samba
    network_mode: host
    command: smbd -F --debug-stdout --no-process-group --option='client min protocol=NT1' --option='server min protocol=NT1' --option='client ipc min protocol=NT1'
    volumes:
      - "./data:/data"
      - "./public:/samba/public"
      - "./share:/samba/share"
      - "./foo:/samba/foo"
      - "./foo-baz:/samba/foo-baz"
    environment:
      - "TZ=Europe/Paris"
      - "SAMBA_LOG_LEVEL=0"
    restart: always

Maybe something has changes, adding the command makes two smbd run, one failing of course, resulting in the container stopping. I sadly still need NT1 for legacy crap.
