How to access to the Linux environment through the login servers

We provides login servers so that you can use Linux environment from outside. This enables you to work on the Linux Environment from outside and to transfer files with the Linux environment.
For use in classes, the remote login service (Linux environment) with GUI is also available. If you can not login, please see here .

Login Server

We provides Login Servers as follows.

• logex00.educ.cc.keio.ac.jp
• logex01.educ.cc.keio.ac.jp
• logex02.educ.cc.keio.ac.jp

Remote Login

By logging in remotely to a login server, you can work in a Linux environment from within the Keio network.
You can also work in a Linux environment from off campus by using SSH public key authentication.
Remote login requires the ssh command or SSH client software.
To use SSH public key authentication, you must create and register a private/public key pair.

Examples of remote login from Windows and Mac are shown below.

• Connecting from the on-campus network
  • Remote Login via SSH
• Connecting from an off-campus network
  • Remote Login Using SSH Public Key Authentication

Restrictions

The Login Servers prioritizes simultaneous use by multiple users and stable operation over long periods of time. Therefore, you MUST NOT run a process that requires high calculation resources for a long time in the servers. Since the process results in inconveniences to other users, we may stop such processes without notice.

In addition, on the Login Servers, some heavy load applications are not available that are installed on the Linux workstations and the remote login service (Linux environment) with GUI.
An Example of the applications that are not available on the Login Servers is as follows. You can use these applications in the workstation room and the remote login service (Linux environment) with GUI.

• Gaussian
• Mathematica
• MATLAB
• Xilinx Vivado SDK

※ Please note that we set limitations of using some applications other than those above on Login Servers without notice.

※ If you want to run heavy load applications for a long time on the purpose of research, please contact ST-KIC.

How to transfer files

In order to transfer files with Linux environment, you need to use sftp command or client software that corresponds to SFTP such as WinSCP.
