log into the K computer by a Secure Shell (SSH) protocol, and how to register a SSH

public key into a login node of the K computer thorough the K computer portal web

site.

4.1. Generating private and public keys

This section describes the procedure for generating a public and private key pair for an

SSH connectivity tool OpenSSH used on UNIX/Linux servers and a terminal emulator

software PuTTY with SSH functions used on Windows systems.

4.1.1 HOW TO USE AN SSH-KEYGEN COMMAND ON UNIX/LINUX SERVERS

To generate a private and public key pair, an ssh-keygen command in the OpenSSH

suite is used.

(1) Launch a terminal emulator at your server and execute the ssh-keygen

command. A passphrase for the SSH connection is required to enter twice in

the prompt. If you use Mac, launch the Terminal and execute the ssh-keygen

command.

Note: Please specify the 2048bit the length of the key.

Note: As with passwords, please choose a character string that is difficult for third parties to guess.

terminal$ ssh-keygen –b 2048 Generating public/private rsa key pair. Enter file in which to save the key (/home/user_name/.ssh/id_rsa): Enter passphrase (empty for no passphrase): ←Enter passphrase Enter same passphrase again: ←Enter same passphrase again Your identification has been saved in /home/user_name/.ssh/id_rsa. Your public key has been saved in /home/user_name/.ssh/id_rsa.pub. The key fingerprint is: f9:81:b6:c7:8f:b9:aa:3e:0e:c6:bd:35:19:a1:1e:06 username@terminal


25

(2) Both a private key (id_rsa) and a public key (id_rsa.pub) are generated in the .ssh

directory in the home directory.

4.1.2 HOW TO USE PUTTYGEN ON WINDOWS PC

To generate a private and public key pair on Windows PC, a terminal emulator PuTTY

needs to be installed beforehand. A command puttygen invokes a utility tool for

generating the pair.

(1) Launch puttygen, then the window “PuTTY Key Generator” appears. Select either

key type ‘’SSH-2 RSA’’ at the bottom of the window and click the “Generate”

button

(2) Move the mouse cursor at random over the blank area (See direction).

1) Select RSA

3) Click the [Generate] button.

2) Input “2048”bit.


26

(3) Enter a passphrase in the “Key passphrase” and the ‘’Confirm passphrase’’ boxes.

Then save the private key by clicking the ‘’’Save private key’’ button. Please make

sure to remember this passphrase, as it will be required when logging in to the K

computer.

(4) Enter a file name in the “Filename(N)” box to save the private key, and click the
