Network Related

1) There is a sufficient number of information outlets (100Base-TX standard) in each laboratory and the common space in the Bioscience Building, and Internet access is available by connecting an Ethernet cable from a computer on which DHCP server setting (automatic address acquisition) is enabled. Currently, this service is provided free of charge.

2) Each laboratory (and B1F) is divided as a subnet, and the number of IP addresses (equal to the number normally available for connection) available for each subnet is limited to 27. Thus, some kind of workaround is needed when you want to connect 28 or more devices at the same time. There are also some restrictions for communication between subnets (e.g. AppleTalk may be blocked).

3) As the DHCP server setting needs to be changed for connecting a device that requires a static address such as printers and file servers, the person in charge of the laboratory's subnet must contact the network committee of the department in advance. In this case, we will need the name of the device, purpose of use, MAC address (device-specific), room of installation, and the person in charge. Currently, it is not allowed for security reasons to install a server that can be accessed freely from outside of Bioscience Building (including the web, e-mail, FTP).

4) An e-mail account is required for student affairs related contacts. For new students of the Department of Integrated Biosciences
who enrolled in 2006 or later, an e-mail address is automatically issued from the department via the mail hosting service of the Information Technology Center. Also, by attending the lecture hosted by the Information Technology Center and obtaining an account for the Educational Campuswide Computing System (ECCS), advanced services such as using the super computer are available."

5) Take extra precautions about handling virus e-mails. Generally, it is recommended to set your e-mail software not to open incoming e-mails automatically, try not to open any suspicious e-mails, and install an anti-virus software. Students are supposed to install anti-virus software on their own computers as well. For details, please ask the person in charge of the network in your laboratory. If there is any suspicion of virus infection, immediately disconnect that device from the network and then take the necessary measures.

6) Refer to the network guide of GSFS for e-mail settings and related information.

7) Also check the Cybozu http://www.k.u-tokyo.ac.jp/f-net/ message board constantly where notices related to our graduate school are posted. Login is not required for access from inside the campus, but you will need a password to access from outside.

8) Prohibition of the use of P2P file sharing software
The use of P2P file sharing software such as Winny is prohibited inside the campus. The destinations from the user are constantly monitored, and records are kept in log files. If the use of P2P file sharing software is detected, the laboratory may be requested to investigate. Be careful not to use any P2P file sharing software.
