  253
  • 15.6.5 Generating public/private keys for SSH (Windows)

    255
• This section describes how to generate and configure SSH keys using Windows.

  255
• First create a new user from the Black Box Management (the following example uses a user called "testuser") making sure it is a member of the "users" group.

  255
• To generate a SSH key using PuTTY http://sourceforge.net/docs/F02/#clients:

  255
• - Execute the PUTTYGEN.EXE program.

  256
• - Select the desired key type SSH2 DSA (you may use RSA or DSA) within the Parameters section.

  256
• - It is important that you leave the passphrase field blank.

  256
• - Click on the Generate button.

  256
• - Follow the instruction to move the mouse over the blank area of the program in order to create random data used by PUTTYGEN to generate secure keys. Key generation will occur once PUTTYGEN has collected sufficient random data.

  256
• #!/bin/sh

  257
• This will run the tunnel redirecting local port 9001 to the server port 4001.
