SFTP Configuration 441
n
If you specify to authenticate a client through public key on the server, the client
needs to read the local private key when logging in to the SFTP server. Since both
RSA and DSA are available for public key authentication, you need to use the
identity-key key word to specify the algorithms to get correct local private key;
otherwise you will fail to log in. For details, see SSH Operation Manual.
SFTP Configuration
Example
Network requirements
As shown in Figure 151, establish an SSH connection between the SFTP client
(switch A) and the SFTP server (switch B). Log in to switch B through switch A to
manage and transmit files. An SFTP user with the user name "client001" and
password "abc" exists on the SFTP server.
