e. The switch compares the decrypted bytes to the original bytes it
sent. If the two sets match, this means that the client's private key
corresponds to an authorized public key, and the client is
authenticated.
Notes: 1. To use SSH with only password authentication, the host public
key must still be given to the client, either during initial
connection or manually entered into the known host file.
However, you do not need to configure the client’s keys.
2. The SSH server supports up to four client sessions. The
maximum number of client sessions includes both current
Telnet sessions and SSH sessions.
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 proceeding section (Command
Usage).
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: RSA)
The SSH server uses RSA or DSA for key exchange when the client
first establishes a connection with the switch, and then negotiates with
