SSH Commands

Page 237

User Guidelines

If encryption keys are not generated, the SSH server is in standby until the keys are generated. To generate SSH

server keys, use the crypto key generate dsa, and crypto key generate rsa Global Configuration mode

commands.

Example

The following example enables configuring the device from a SSH server.

crypto key generate dsa

The crypto key generate dsa Global Configuration mode command generates DSA key pairs.

Syntax

crypto key generate dsa

Default Configuration

DSA key pairs do not exist.

Command Mode

Global Configuration mode

User Guidelines

DSA keys are generated in pairs: one public DSA key and one private DSA key. If the device already has DSA

keys, a warning and prompt to replace the existing keys with new keys are displayed.

This command is not saved in the device configuration; however, the keys generated by this command are saved

in the private configuration, which is never displayed to the user or backed up on another device.

DSA keys are saved to the backup master.

This command may take a considerable period of time to execute.

Example

The following example generates DSA key pairs.

crypto key generate rsa

The crypto key generate rsa Global Configuration mode command generates RSA key pairs.

Syntax

crypto key generate rsa

Default Configuration

RSA key pairs do not exist.

Console(config)# ip ssh server

Console(config)# crypto key generate dsa
