Basic Information

A Virtual Domain Server (VDS) is a service that hosts mail, Domain Name System (DNS), websites, and other services on a server in the Information Technology Center. It is provided as one of the UEC private cloud services. Please refer to Service Details for the details of the features and limitations.

The advantages of using this service include

• No server hardware maintenance (e.g., during power outages)

• No server software administration (security updates, etc.)

• No IP address management work is required.

• Users can focus on managing their content (web pages, email accounts, DNS records).

It has the above advantages. On the other hand, the disadvantage is that

• Users cannot add their own plug-ins or settings to the server software.

• Because the server is shared with other tenants, capacity and performance are not guaranteed (best-effort operation).

The above are some of them.

How to use

1. Confirm the domain to be used.

Decide the domain to be used. If you wish to use a new domain directly under uec.ac.jp, please apply for it separately referring to Subdomains directly under uec.ac.jp.

Service Details

mail

This service provides sending/receiving mail and mailing list functions using your own subdomain. SMTP can be used for sending mail, POP3 or POP3s can be used for receiving mail, IMAP cannot be used. IMAP is not available. You can also set up mail forwarding for those who have moved out.

**Sending and receiving mails by this service is available only from the campus network. ** If you want to use this service from off-campus, please use VPN service.

本サービスの利用にあたり，メールアカウントおよびメーリングリスト管理者が必要です． 管理者はウェブインタフェースからメールアカウントの管理やメーリングリストの構築・設定を行います．

詳しい利用方法は メールサーバ利用者向けのマニュアル 学内 をご覧ください．

Please note the following points when using this service.

• DNS registration is required to ensure that mail is delivered to the requested domain.

• メールサービス立ち上げ後，CatchAllの設定を必ず行ってください．

  • CatchAllの設定とは，送信されてきたメールアドレス（メーリングリスト，転送設定を含む）が存在しなかった際，相手がいなかった旨のエラーメールを誰が受け取るのか，を設定することです．

    センターでは，メールサービス責任者あるいは専用のメールアカウントを用意し，そちらに向けて配送させるようCatchAllの設定をして頂く事をお願いしております．

    • 現在，迷惑メールの送信手段の 1 つに，わざと存在しないメールアドレスにメールを送り，

      これにより生じたエラーメールをメール送信元として詐称された相手（迷惑メールの送信対象）に送信させるという方法があります．

      ここで問題なのは，このエラーメールを送信するメールサーバ（本稿の場合，バーチャルドメインサーバ）が迷惑メールの発信源として認識されてしまう事です．

      エラーメールを無制限に送信元へ返信させる状態のままにしてありますと，迷惑メールの調査機関から，本学が迷惑メールの発信源として認定されてしまう恐れがあります．

      もし，発信源として認定されてしまいますと，皆さまが送られる普通のメールも送信先，あるいは配送途中で迷惑メールとして扱われ，結果，メールが届かない事態が発生します．

    以上の理由により，CatchAllの設定へのご協力をよろしくお願いいたします．CatchAllの設定の詳細については，2.1.5 CatchAllアカウント をご参照ください．

• If you put the mailing list address in the blind carbon copy (Bcc:), the mail will not be delivered.

• If you nest mailing lists, mail will not be sent to the inner mailing list.

  • 例えば，以下のようなメーリングリスト（members, students）を作成したとします．

    • members@xxx.uec.ac.jp →

      professor@xxx.uec.ac.jp students@xxx.uec.ac.jp

    • students@xxx.uec.ac.jp →

      hoge@xxx.uec.ac.jp fuga@xxx.uec.ac.jp piyo@xxx.uec.ac.jp

    このとき，students宛てに直接メールを送るとhoge，fuga，piyo，…にメールは送信されます． しかし，members宛てにメールを送るとprofessorにはメールが届きますが，hoge，fuga，piyo，…宛てにはメールが届きません． さらに送信者に対して配送できなかった旨のエラー通知もされません．

    そのため，上記のような送り方を想定される場合は，studentsをメーリングリストとして構築するのではなく，hoge，fuga，piyo，…宛てに転送するようにサービスを構築してください．

• Approval is also required for the moderator’s (the person who checks the post in advance) own post.

  If the mailing list is moderated, the moderator’s own posts will also require approval. When a moderator posts an email to the mailing list, an email with the subject 「MODERATE for …」 will be sent to the moderator. When replying, please make sure that the address is list-name-accept-random-string@domain-name.

• モデレータのメールアドレスとして別のメーリングリストを指定することはできません． モデレータのメールアドレスとして別のメーリングリストを登録しても，モデレーション機能が正しく動作しません． メーリングリストではない，個人のメールアドレスを登録してください．

Caution

In order to use this service, DNS settings (SPF using A records, MX records, and TXT records) are required for the host name you have applied for. Please consult with your domain administrator in advance.

DNS

Caution

Due to the introduction of Subdomain DNS Record Management System, the DNS service for virtual domain servers will stop accepting new registrations from November 1, 2023. We will guide you how to use Subdomain DNS Record Management System when you register a subdomain.

This service provides DNS services using BIND9. The user does not manage the DNS server itself, but only manages the zone (file).

It is operated as a split DNS where the internal zone and the external zone are separated. Therefore, different responses can be returned for DNS access from within the university and DNS access from outside the university. It is possible to set host names for private addresses in the zone for internal use, and host names for global addresses assigned to public servers in the zone for external use, etc.

本サービスの利用には，BIND9 のゾーン ファイルを適切に編集する技能をもった管理者が必要です． ゾーンファイル管理者は，ホスト名とIPアドレスの対応付けを行ない，その情報を基にして ゾーンファイルを作成し，FTP によってバーチャルサーバに転送します．

The transferred zone file will automatically become effective in about five minutes. The user is responsible for managing the zone file and contacting the high-level domain.

Web

This service provides a space to place web pages that can be viewed from inside and outside the university. It is also possible to create dynamic content using CGI or PHP.

In order to use this service, an administrator is required to manage the contents of the web pages (web contents). The administrator creates the web pages and transfers the created web pages to the server by FTP.

From the virtual server, it is possible to obtain access logs and error logs for the web content.

Caution

In order to use this service, DNS settings (SPF using A records, MX records, and TXT records) are required for the host name you have applied for. Please consult with your domain administrator in advance.

Warning

2016年 3月以降にサービスが開始されたバーチャルドメインサーバ（post-4, post-5）では， SSL/TLS プロトコルによって提供されるセキュアな接続を行うHTTP通信（HTTPS）を行うことが可能となりました．

Operation

現在，下記のサーバが稼働しています．

現在，業務・教育用のDNSサービスは post-1, 2 に，メールサービスは post-9, 10 に， ウェブサービスは post-4, 6, 7, 8 上にサービスを構築しています． 学友会・サークル活動用のメールサービスは post-3 上に， ウェブサービスについては post-5 上にサービスを構築しています．

Each server has a different operation method. Click on the link in the table to view the administration manual for each server.
