Generating public keys for Windows
To use the PuTTY Key Generator application to create the basic key:
1 Start the application and select RSA for the key type.
2 Enter the number of bits for the key. The number of bits must be between 2048 and 4096 bits.
3 Click Generate and move the mouse in the window as directed.
The keys are generated.
4 You can modify the key comment eld.
5 Enter a passphrase to secure the key.
6 Save the public and private key.
Generating public keys for Linux
To use the ssh-keygen application to create the basic key, open a terminal window and at the shell prompt, enter ssh-keygen –t rsa
–b 2048 –C testing
where:
• -t is rsa.
• –b species the bit encryption size between 2048 and 4096.
• –C allows modifying the public key comment and is optional.
NOTE
: The options are case-sensitive.
Follow the instructions. After the command executes, upload the public le.
CAUTION
: Keys generated from the Linux management station using ssh-keygen are in non-4716 format. Convert the keys into
the 4716 format using ssh-keygen -e -f /root/.ssh/id_rsa.pub > std_rsa.pub. Do not change the permissions of
the key le. The conversion must be done using default permissions.
NOTE: iDRAC does not support ssh-agent forward of keys.
Uploading SSH keys
You can upload up to four public keys per user to use over an SSH interface. Before adding the public keys, make sure that you view the
keys if they are set up, so that a key is not accidentally overwritten.
When adding new public keys, make sure that the existing keys are not at the index where the new key is added. iDRAC does not perform
checks to make sure previous key(s) are deleted before a new key(s) are added. When a new key is added, it is usable if the SSH interface
is enabled.
Uploading SSH keys using web interface
To upload the SSH keys:
1 In the iDRAC Web interface, go to Overview > iDRAC Settings > Network > User Authentication > Local Users.
The Users page is displayed.
2 In the User ID column, click a user ID number.
The Users Main Menu page is displayed.
3 Under SSH Key Congurations, select Upload SSH Key(s) and click Next.
The Upload SSH Key(s) page is displayed.
