Task Remarks
877H
Configuring a client's host public key
Required if publickey authentication is configured for
users and the clients directly send the public keys to
the server for validity check.
Configuring the PKI domain of the client certificate
See VPN Configuration Guide.
Required if publickey authentication is configured for
users and the clients send the public keys to the server
through digital certificates for validity check.
The PKI domain must have the CA certificate to verify
the client certificate.
878H
Configuring an SSH user
Required for publickey authentication users and
optional for other authentication users.
879H
Setting the SSH management parameters Optional.
274BGenerating local DSA or RSA key pairs
DSA or RSA key pairs are required for generating the session key and session ID in the key exchange
stage, and can also be used by a client to authenticate the server. When a client tries to communicate
with a server, it compares the public key that it receives from the server with the server public key that it
saved locally. If the keys are consistent, the client uses the public key to authenticate the digital signature
that receives from the server. If the digital signatures are consistent, the authentication succeeds. If the
digital signatures are consistent, the authentication succeeds.
The public-key local create rsa command generates a server RSA key pair and a host RSA key pair. Each
of the key pairs consists of a public key and a private key. The public key in the server key pair of the SSH
server is used in SSH1 to encrypt the session key for secure transmission of the key. As SSH2 uses the DH
algorithm to generate the session key on the SSH server and client respectively, no session key
transmission is required in SSH2 and the server key pair is not used.
The public-key local create dsa command generates only the host key pair. SSH1 does not support the
DSA algorithm.
To support SSH clients that use different types of key pairs, generate both DSA and RSA key pairs on the
SSH server.
To generate local DSA or RSA key pairs on the SSH server:

Command Remarks
1. Enter system view.
system-view N/A
2. Generate DSA or RSA key
pairs.
public-key local create { dsa | rsa }
By default, neither DSA key pair
nor RSA key pairs exist.
NOTE:
In FIPS mode, the router does not support a DSA key pair.
275BEnabling the SSH server function
The SSH server function on the device allows clients to communicate with the device through SSH.
