Generating public keys for systems running Windows

Before adding an account, a public key is required from the system that accesses the CMC over SSH. There are two ways to generate the

public/private key pair: using PuTTY Key Generator application for clients running Windows or ssh-keygen CLI for clients running Linux.

This section describes simple instructions to generate a public/private key pair for both applications. For additional or advanced usage of

these tools, see the application Help.

To use the PuTTY Key Generator to create a basic key for clients running Windows:

1 Start the application and select SSH-2 RSA for the type of key to generate (SSH-1 is not supported).

2 Enter the number of bits for the key. Ensure that the RSA key size is between 1024 and 4096.

NOTE:

• CMC may not display a message if you add keys less than 1024 or greater than 4096, but when you try to log in with these

keys, it fails.

• CMC accepts RSA keys up to key strength 4096, but the recommended key strength is 1024.

3 Click Generate, and move the mouse in the window as directed.

After the key is created, you can modify the key comment eld.

You can also enter a passphrase to make the key secure. Ensure that you save the private key.

4 You have two options for using the public key:

• Save the public key to a le to upload later.

• Copy and paste the text from the Public key for pasting window when adding the account using the text option.

Generating public keys for systems running Linux

The ssh-keygen application for Linux clients is a command line tool with no graphical user interface. Open a terminal window and at the

shell prompt type:

ssh-keygen –t rsa –b 1024 –C testing

where,

–t must be rsa.

–b species the bit encryption size between 768 and 4096.

–c allows modifying the public key comment and is optional.

The < passphrase > is optional. After the command completes, use the public le to pass to the RACADM for uploading the le.

Accessing CMC web interface

Before you log in to CMC using the web interface, make sure that you have congured a Supported Web Browser and the user account is

created with the required privileges.

NOTE

: If you are using Microsoft Internet Explorer, connect using a proxy, and if you see the error The XML page cannot be

displayed, you must disable the proxy to continue.

To access the CMC web interface:

1 Open a web browser supported on your system.
