KSMBD

From NixOS Wiki

KSMBD is a linux kernel server which implements SMB3 protocol in kernel space for sharing files over network.

Example configuration

The following example will create a read-only file share of /var/lib/ksmbd with guest login enabled.

{
  services.ksmbd.enable = true;
  services.ksmbd.openFirewall = true;
  services.ksmbd.shares.public = {
    path = "/var/lib/ksmbd";
    "read only" = true;
    browseable = "yes";
    "guest ok" = "yes";
    comment = "Public samba share.";
  };
}
