Your Account for the Tutorials

In order to make your account on the tutorial server, please send the following information to pat06.support@icepp.s.u-tokyo.ac.jp.
• your preferred login name (up to eight letters. please list more than one candidates, for there can be conflicts with other accounts)
• your preferred login shell (you will not be able to change it later for technical reasons)
• your SSH public key (either as an attachment or inline)

In case you don't have a SSH key and don't know how to get it, please read the following instructions.

SSH Key

If you use Linux, FreeBSD, Mac OS X, or cygwin, you are most likely using OpenSSH.

• OpenSSH
Otherwise;
• PuTTY
• Tera Term

If you have any other SSH application, please consult its documents. If you have no SSH application on your PC, please first install some. See our instruction page if you need help.

OpenSSH

If you are using OpenSSH (on GNU, Linux, cygwin, MacOS X, etc.),
1. Generate the key pair;

     ssh-keygen -t rsa 

   Or, in case you need to make ver.1 SSH key for some reason;

     ssh-keygen -t rsa1 

2. Hit [RETURN] key to choose the default key file path.
3. Type in whatever phrase as your "passphrase", and keep it in mind. Passphrase is something different from a password. You will need it when you use the SSH key.
4. The public key file is "~/.ssh/id_rsa.pub", which you send us by e-mail, and the private key is "~/.ssh/id_rsa", which you keep on your PC securely. If you generated a ver.1 key pair with '-t rsa1' option, the publick key is in "~/.ssh/identity.pub" and the private key in "~/.ssh/identity".
• Please note that you might need to execute 'ssh' command with '-2' option

    ssh -2 patws01.icepp.s.u-tokyo.ac.jp

  instead of just 'ssh', when the default protocol on your PC is SSH1.

PuTTY

You can either
• Generate a key pair with PuTTYgen ('puttygen.exe') and convert the public key into OpenSSH format which you can send to us.
• Generate a key pair with OpenSSH on for example LXPLUS, and send the public key to us and copy the private key to your PC.
Please read the PuTTY User Manual for details.

In order to generate a key pair with PuTTYgen;

1. Run 'puttygen.exe'.
2. Select "SSH2 RSA"
3. Press the "Generate" button.
4. Set whatever a comment for your key and a passphrase which you should never forget to use the key.
5. Save the private key.
6. Copy the character string inside the frame beneath "Public key for pasting into OpenSSH authorized_keys file:", and paste it into the e-mail you send to us.
7. Or, in "Conversions" menu, choose "Export OpenSSH key" and send the exported public key.

In order to use a SSH key generated not by PuTTY

1. Run 'puttygen.exe'.
2. In "Conversions" menu, choose "Import".
3. Press "Save public key".

Tera Term

Tera Term has no functionality to generate a SSH key, but you can import Keys from other system. First, you make a key pair with OpenSSH on for example LXPLUS, then send us the public key by e-mail and copy the private key to your PC.

UTF-8 TeraTerm Pro with TTSSH2
When you start Tera Term, choose "Use RSA/DSA key to login" and specify the file.

Old Tera Term + TTSSH
When you start the application, choose "RSA" and specify the file.
