sshpkauth

Description

Enables you to upload and manage up to four different SSH public keys per user. You can upload a key file or key text, view keys, or delete keys.

RSA key size should be between 768 and 4096 and the recommended DSA key size is 1024.

This command has three mutually exclusive modes—upload, view, and delete that are determined by the options.

Upload

The upload mode allows you to upload a keyfile or to copy the key text on the command line. You cannot upload and copy a key at the same time.

Remote RACADM:

racadm sshpkauth -i <
                                                2 to 16> -k <
                                                1 to 4> -f <
                                                filename>

racadm sshpkauth -i <
                                                2 to 16> -k <
                                                1 to 4> -t

<
                                                key-text>

Telnet/ssh/serial RACADM:

racadm sshpkauth -i <
                                                2 to 16> -k <
                                                1 to 4> -t

<
                                                key-text>

View

The view mode allows the user to view a key specified by the user or all keys.

racadm sshpkauth -i <
                                                2 to 16> -v -k <
                                                1 to 4>

racadm sshpkauth -i <
                                                2 to 16> -v -k all

Delete

The delete mode allows the user to delete a key specified by the user or all keys.

racadm sshpkauth -i <
                                                2 to 16> -d -k <
                                                1 to 4>

racadm sshpkauth -i <
                                                2 to 16> -d -k all

Synopsis

racadm sshpkauth

NOTE:

For DSA keys greater than 2048, use the following racadm command. CMC accepts RSA keys up to key strength 4096, but the recommended key strength is 1024.

racadm -r 192.168.8.14 -u root -p <default root user password> sshpkauth -i svcacct -k 1 -p 0xfff -f dsa_2048.pub

Input

-i < user index > - Index for the user. < user index> must be between 2 and 16 on iDRAC.
-k [< key index > | all] - Index to assign the PK key being uploaded. all only works with the -v or -d options. < key index> must be between 1 and 4 or all on iDRAC.
-t < PK Key Text > - Key text for the SSH Public key.
-f < filename > - File containing the key text to upload. The -f option is not supported on Telnet/ssh/serial RACADM.
-v - View the key text for the index provided.
-d - Delete the key for the index provided.

Examples :

Upload an invalid key to iDRAC User 2 in the first key space using a string:

$ racadm sshpkauth -i 2 -k 1 -t "This is invalid key
                                          Text"

ERROR: Key text appears to be corrupt

Upload a valid key to iDRAC User 2 in the first key space using a file:
```
$ racadm sshpkauth -i 2 -k 1 -f pkkey.key
```
```
Key file successfully uploaded.
```

Get all keys for User 2 on iDRAC:

$ racadm sshpkauth -v -i 2 -k all
