    • The list of administrators having authority to manage the shared server of a domain can be edited by any domain administrator. An initial administrator is an administrator who is registered the first to edit the list of administrator.

    • An initial administrator is not always the person responsible for payment. Register a university staff member in charge of the management of the server. For example, we assume that the person responsible for payment is a professor, and the initial administrator is an assistant professor.
      • You can add a student to the list of administrators as an auxiliary administrator.
    • As the initial administrator, apply for the registration of a university staff member.

    • A center account is assigned to all university staff members. In case you do not know your account, contact Center Staff Room 1.

      • For fourth-level domains, domain names that are already assigned to each department/center are used. Requests for a domain inconsistent with the domain name assignment policy for fourth-level domains are not accepted.
        • For example, when a laboratory that belongs to Department 4 requests a domain name, which does not comply with the already assigned fourth level domain of Department 4, which is, such request is not accepted.
        • This does not mean that the domain name must always contain For example, when a laboratory that belongs to Department 4 requests the domain “,” there is no problem.
      • Requests for domains that are the same as existing domains are not accepted.

Service contents

The shared server provides a virtual domain environment.

  • It provides mail server and web server for the existing (or new) domain using the equipment in the center.
  • User names of a domain can be mapped with accounts of the center. This enables the following:
    • Email to a user of another domain can be received by an account of the Information and Media Center.
    • Contents placed under the home directory of the Information and Media Center are published as the personal web page of a domain user.
  • Mail aliases (registration of another name for an email address) of a user can be set without limitation. This helps you create a simple mailing list.
  • The contents of the web server of a domain can be remotely edited, registered and published.

The following describes the example when applying for a virtual domain

    • Another name (alias) can be added.
