Information Technology Team > Host management system

日本語

1 Outline

The University of Tokyo requires that all the computers using the university's network must be properly managed. A university-wide security firewall is in place. It is recommended that personal computers use a university-wide private network called the PROTECTED network.

Depending on the major and facility, the computer may be connected to the conventional networks. The SoS DHCP Management system manages the computer that are connected to conventional networks by automatically setting IP addresses by DHCP.

2 Preparation for use

2.1 Subnet administrator

Ask the Information Technology Team by e-mail to implement host management using DHCP by the host management system.

For host management, including the process of implementation, see the page below.

Host management (Japanese) (information for subnet administrators)

2.2 Preparation by users

To log in to this system, use the client certificate issued by the School of Science account.

School of Science account

3 “Login” page

Access the following URL to log into SoS DHCP Management system (subnet administrators can also access the URL to log into the system).

SoS DHCP Management system

4 Procedures for using the service

Visit the URL above to access the “Login” page.

A list of registered hosts is displayed.
Enter the "MAC address" and "Description" of the computer to be registered and press the "Add host" button to register, and the settings will be reflected in about 10 minutes.

You can remove by pressing the "Remove" button on the right side of the registered host.

5 Procedures for administrators

The “Login” page is the same as that for users.
If you have administrator privileges, the "Admin menu" is also displayed.
The following menu options are available
- Admins: Add, confirm, or remove subnet administrators.
- Address ranges: Add, confirm, or remove IP address ranges for DHCP.
- Registered hosts: Add, confirm, or remove registered hosts.
- Fixed assignments: Add, confirm, or remove hosts with fixed IP addresses for DHCP.
- Leases: View a list of currently leased IP addresses.

The first thing you need to set is the address range. Enter the range of IP addresses used for DHCP. This can be changed at any time. The setting itself will be reflected in about 10 minutes, but the address already in use will be changed after the lease time (30 minutes) has elapsed.

-The University of Tokyo requires that all host terminals accessing the University’s information networks be properly managed.  DHCP eliminates the necessity for each user to manually assign an IP address to the host, minimizing setup problems.  At the same time, it involves managing MAC addresses for host management.
+The University of Tokyo requires that all the computers using the university's network must be properly managed.
-The School of Science host management system assumes that each user logs into the system and registers his/her host MAC address.  It provides proper host management by assigning IP addresses to only registered hosts via DHCP.
+A university-wide security firewall is in place.
+It is recommended that personal computers use a university-wide private network called the PROTECTED network.
-== Supported users ==
+Depending on the major and facility, the computer may be connected to the conventional networks.
-All faculty and students with an account for the School of Science authentication system can use the host management system (as long as, in the relevant Department/Facility subnet, MAC addresses are managed via DHCP by the host management system).
+The SoS DHCP Management system manages the computer that are connected to conventional networks by automatically setting IP addresses by DHCP.

-* Fill in the “MAC address” and “Description” fields.
+* A list of registered hosts is displayed.
-* For a host with multiple interfaces to access wired and Wi-Fi networks, apply for a host registration for each interface.
+* Enter the "MAC address" and "Description" of the computer to be registered and press the "Add host" button to register, and the settings will be reflected in about 10 minutes.
-* No application is required for Wi-Fi and VPN networks that support automatic registration.
-* In the “Description” field, enter the PC’s name or model name to facilitate the subsequent identification of the host.
-* If your Department/Facility subnet has been configured not to require approval, the host is registered immediately upon applying for a host registration.
-* If your Department/Facility subnet has been configured to require approval, the host is registered after the subnet administer receives and approves the application.
-* Access via DHCP becomes available about 10 minutes after registration.
-* In the “Registered” page, registered hosts can be confirmed.
+[[ファイル:Dhcp2-2.png]]
-* Guests can also be registered for DHCP access.
+* You can remove by pressing the "Remove" button on the right side of the registered host.
-* For all subnets, guest registration does not require approval.
-* The registration is automatically removed in 24 hours.
-* The guest registration allows DHCP address assignment for access to the relevant Department/Facility subnet via DHCP.  For guest access to Wi-Fi, click here.
 == Procedures for administrators ==
 * The “Login” page is the same as that for users.
-* For the use of administrator menu options, log into the system with the certificate.

-* Administrators can use the Subnet Menu in addition to the User Menu.
+* The following menu options are available
-* The following Subnet Menu options are available (User Menu options are also available).
+** Admins: Add, confirm, or remove subnet administrators.
