Generating the Host Key Pair
A host public/private key pair is used to provide secure communications between an
SSH client and the switch. After generating this key pair, you must provide the host
public key to SSH clients and import the client’s public key to the switch as
described in the section Importing User Public Keys on page 3-95.
Field Attributes
•
Public-Key of Host-Key
– The public key for the host.
- RSA (Version 1): The first field indicates the size of the host key (e.g., 1024), the
second field is the encoded public exponent (e.g., 65537), and the last string is
the encoded modulus.
- DSA (Version 2): The first field indicates that the encryption method used by
SSH is based on the Digital Signature Standard (DSS). The last string is the
encoded modulus.
•
Host-Key Type
– The key type used to generate the host key pair (i.e., public and
private keys). (Range: RSA (Version 1), DSA (Version 2), Both; Default: Both)
The SSH server uses RSA or DSA for key exchange when the client first
establishes a connection with the switch, and then negotiates with the client to
select either DES (56-bit) or 3DES (168-bit) for data encryption.
Note:
The switch uses only RSA Version 1 for SSHv1.5 clients and DSA Version 2 for
SSHv2 clients.
•
Save Host-Key from Memory to Flash
– Saves the host key from RAM (i.e.,
volatile memory) to flash memory. Otherwise, the host key pair is stored to RAM
by default. Note that you must select this item prior to generating the host-key pair.
•
Generate
– This button is used to generate the host key pair. Note that you must
first generate the host key pair before you can enable the SSH server on the SSH
Server Settings page.
•
Clear
– This button clears the host key from both volatile memory (RAM) and
non-volatile memory (Flash).
