 iRMC 

S2/S3

In addition to authentication by means of a user name and password, the 
iRMC S2/S3 also supports SSHv2-based public key authentication using pairs 
of public and private keys for local users. To implement SSHv2 public key 
authentication, the SSHv2 key of an iRMC S2/S3 user is uploaded to the 
iRMC S2/S3 and the iRMC S2/S3 user uses their private key with the program 

 or the OpenSSH client program 

, for example.

The iRMC S2/S3 supports the following types of public keys:

–

SSH DSS (minimum requirement)

–

SSH RSA (recommended)

The public SSHv2 keys that you upload to the iRMC S2/S3 can be available 
either in RFC4716 format or in OpenSSH format (see 

).

In outline, public key authentication of a user on the iRMC S2/S3 happens as 
follows:

The user who wishes to log into the iRMC S2/S3 creates the key pair:

–

The private key is read-protected and remains on the user's computer. 

–

The user (or administrator) uploads the public key to the iRMC S2/S3.

If the configuration allows this, the user can now log into the iRMC S2/S3 
extremely securely and without the need to enter a password. The user is only 
responsible for keeping their private key secret.

The following steps are necessary to set up private key authentication. They are 
described in the subsequent sections:

1. Creating the public and private SSHv2 keys with the program 

 or 

 and saving them in separate files (see 

2. Loading the public SSHv2 key onto the iRMC S2/S3 from a file 

(see 

3. Configuring the program 

 or 

 for SSHv2 access to the iRMC S2/S3
