# Revised 2022-10-22, Rohhie, as follows:

# - logs to stderr.
|
||||||
|
# - Server name, domain name and DNS admin name are now specified in
|
||||||
|
# environment variables.
|
||||||
|
# - Since the assumption is that the user has been created,
|
||||||
|
# the test logic was removed.
|
||||||
|
# - Moved the parameter "-s" in the klist command.
|
||||||
|
# - When expired, the host name is retrieved from the target IP address.
|
||||||
|
# - Added processing to support IPv6
|
||||||
|
# (works as far as I want to use it in my home lab).

# Samba-ad-dc-ddns-docker
|
||||||
|
|
||||||
|
## 概要
|
||||||
|
|
||||||
|
Samba ad dcと連携するDHCPサーバーをDockerで気軽に利用する。
|
||||||
|
|
||||||
|
## 構築方法
|
||||||
|
### ダウンロード
|
||||||
|
|
||||||
|
このリポジトリからソースをダウンロードする。
|
||||||
|
|
||||||
|
```
|
||||||
|
git clone https://gitea.rohhie.net/rohhie/samba-ad-dc-ddns-docker.git ddns
|
||||||
|
cd ddns
|
||||||
|
```
|
||||||
|
|
||||||
|
### 動作条件を設定
|
||||||
|
#### コンテナ
|
||||||
|
|
||||||
|
docker-compose.ymlには、IPv4とIPv6の2つのコンテナを定義してある。
|
||||||
|
どちらか一方を利用する場合は、使わない方をコメントアウトしておく。
|
||||||
|
|
||||||
|
それぞれの動作条件を設定する。
|
||||||
|
|
||||||
|
| 変数名 | 設定内容 |
|
||||||
|
|------------|--------------------------------------------------------------------------|
|
||||||
|
| DHCPIF | 使用するネットワークインターフェースを設定。空白で区切って複数指定可能。 |
|
||||||
|
| DHCPSERVER | Samba AD DCのホスト名を指定。名前解決できる(はず)。 |
|
||||||
|
| DHCPDOMAIN | ドメインのFQDNを指定。 |
|
||||||
|
| DHCPDNSADM | DnsAdminsのユーザー名を指定。 |
|
||||||
|
| DHCPDBGFLG | "true"を指定すると、標準出力にデバッグ情報が出力される。 |
|
||||||
|
|
||||||
|
#### IPv4
|
||||||
|
|
||||||
|
v4ディレクトリにdhcpd.confがあるので、これを適宜書き換える。
|
||||||
|
|
||||||
|
#### IPv6
|
||||||
|
|
||||||
|
v6ディレクトリにdhcpd.confとradvd.confがあるので、適切に設定。
|
||||||
|
radvd.confでは、使用するネットワークインターフェースの設定があるので、環境変数DHCPIFとあわせて設定しておく。
|
||||||
|
|
||||||
|
#### Kerberos
|
||||||
|
|
||||||
|
krb5.confをSamba ad dcにアクセスできるように作成。
|
||||||
|
|
||||||
|
#### keytab
|
||||||
|
|
||||||
|
Samba ad dcでDnsAdminに所属するユーザーのkeytabを取り出す。
|
||||||
|
ホームラボでは、Samba ad dc立ち上げ時にssoauthというユーザーを作りDnsAdminにしたので、これを使っている。
|
||||||
|
新たにユーザーを作っても良いし、既存のユーザーを使っても良い。
|
||||||
|
```
|
||||||
|
<username>.keytab
|
||||||
|
```
|
||||||
|
という名前で保管しておく。
|
||||||
|
ホームラボではssoauth.keytabという名前で保管している。
|
||||||
|
|
||||||
|
#### dhcp-dyndns.sh
|
||||||
|
|
||||||
|
これは、Samba Wiki(https://wiki.samba.org/index.php/Configure_DHCP_to_update_DNS_records)にあるスクリプトをベースにして、IPv6の処理を追加している。
|
||||||
|
ユーザーはssoauthとしているので、DnsAdminのユーザー名に置換して使用する。
|
||||||
|
|
||||||
|
### ファイアウォールの設定
|
||||||
|
|
||||||
|
ファイアウォールを設定するスクリプトを実行する。
|
||||||
|
このスクリプトではIPv6のみ開放している。
|
||||||
|
IPv4は開放しなくてもうまく動いている。
|
||||||
|
|
||||||
|
```
|
||||||
|
sudo ./setufw.sh
|
||||||
|
```
|
||||||
|
|
||||||
|
何らかの理由で設定を解除するなら、以下を実行する。
|
||||||
|
|
||||||
|
```
|
||||||
|
sudo ./setufw.sh delete
|
||||||
|
```
|
||||||
|
|
||||||
|
### コンテナを起動
|
||||||
|
|
||||||
|
コンテナを構築して起動する。
|
||||||
|
|
||||||
|
```
|
||||||
|
sudo docker compose up -d --bulid
|
||||||
|
```
|
||||||
|
|
||||||
|
## その他
|
||||||
|
|
||||||
|
細かな設定手順や使い方は、メインサイト参照。
|
||||||

## ライセンス
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
ただし、dhcp-dyndns.shだけはソースコード参照。
|
||||||
|
変更点は原作に準じてGPL3.0以降とする。

# Revised 2022-10-22, Rohhie, as follows:
|

|
# - ログをstderrに出力するようにした。
|

|
# - サーバー名とドメイン名、DNS管理者ユーザー名を環境変数で指定するようにした。
|

|
# - ユーザーは作ってある前提なのでテストロジックを削除した。
|
||||||
|
# - klistの-s指定をファイル名の前に移動した。
|
||||||
|
# - 期限切れで削除になる時、対象IPアドレスからホスト名を取得するようにした。
|

# - IPv6に対応する処理を追加した(ホームラボで使いたい範囲で動く程度)。
