Configuration procedure
1 Configure the client to perform the first-time authentication of the server.
[3Com] ssh client first-time enable
2 Specify the public key of the server on the client.
[3Com] rsa peer-public-key hello
[3Com-rsa-public-key] public-key-code begin
[3Com-rsa-key-code] 308186028180739A291ABDA704F5D93DC8FDF84C427463

[3Com-rsa-key-code] public-key-code end
[3Com-rsa-public-key] peer-public-key end
[3Com] ssh client 10.165.87.136 assign rsa-key hello
CAUTION: Before logging into the SSH server, the SSH client (except for the
software Putty and Openssh) must configure the public key of the server.
3 Start the SSH client.
The following shows the configuration methods for both password authentication
and RSA public key authentication.
Employ password authentication mode, and start using the default
encryption algorithm
