Importing the client's host public key from the public key file
Before you import the host public key, upload the client's public key file (in binary) to the server, for
example, through FTP or TFTP. During the import process, the server automatically converts the host
public key in the public key file to a string in PKCS format.
To import a client's host public key from the public key file:
Step Command
1.
Enter system view.
system-view
2.
Import a client's public key
from a public key file.
public-key peer
keyname
import sshkey
filename
Configuring an SSH user
Configure an SSH user and a local user depending on the authentication method.
•
If the authentication method is
publickey
, you must create an SSH user and a local user on the SSH
server. The two users must have the same username, so that the SSH user can be assigned the
correct working directory and user role.
•
If the authentication method is
password
, you must perform one of the following tasks:
{
For local authentication, configure a local user on the SSH server.
{
For remote authentication, configure an SSH user on a remote authentication server, for
example, a RADIUS server.
You do not need to create an SSH user by using the
ssh user
command. However, if you want to
display all SSH users, including the password-only SSH users, for centralized management, you
can use this command to create them. If such an SSH user has been created, make sure you have
specified the correct service type and authentication method.
•
If the authentication method is
password-publickey
or
any
, you must create an SSH user and
perform one of the following tasks:
{
For local authentication, configure a local user on the SSH server.
{
For remote authentication, configure an SSH user on a remote authentication server, for
example, a RADIUS server.
In either case, the local user or the SSH user configured on the remote authentication server must
have the same username as the SSH user.
Configuration guidelines
When you configure an SSH user, follow these restrictions and guidelines:
•
An SSH server supports up to 1024 SSH users.
•
For an SFTP or SCP user, the working directory depends on the authentication method.
{
If the authentication method is
password
, the working directory is authorized by AAA.
{
If the authentication method is
publickey
or
password-publickey
, the working folder is specified
by the
authorization-attribute
command in the associated local user view.
•
For an SSH user, the user role also depends on the authentication method.
{
If the authentication method is
password
, the user role is authorized by the remote AAA server
or the local device.
