DGS-1250 Series Gigabit Ethernet Smart Managed Switch CLI Reference Guide Parameters NAME password publickey URL hostbased URL host-name HOSTNAME IP-ADDRESS IPV6-ADDRESS Specifies the username to configure the authentication type. The user must be an existing local account. The length of the username is limited to a maximum of 32 characters. Specifies to use the password authentication method for this user account. This is the default authentication method. Specifies to use the public key authentication method for this user account. Enter the URL of a local file to be used as the public key of this user. Specifies to use the host-based authentication method for this user account. Enter the URL of a local file to be used as client's host key. Specifies the allowed host name for host-based authentication. During authentication phase, the client's hostname will be checked. The range is from 1 to 255. (Optional) Specifies whether to additionally check the IP address of the client for host-based authentication. If not specified, only the host name will be checked. (Optional) Specifies whether to additionally check the IPv6 address of the client for host-based authentication. If not specified, only the host name will be checked. Default The default authentication method for a user is password. Command Mode Global Configuration Mode. Usage Guideline The administrator can use this command to specify authentication method for a user. The user name must be a user created by the username command. By default, the authentication method is password. The system will prompt the user to input the password. To authenticate a user via SSH public key authentication, copy the user's public key file to file system. When the user tries to login to the Switch via an SSH client (using the SSH public key method), the SSH client will automatically transmit the public key and signature with the private key to the Switch. If both the public key and signature are correct, the user is authenticated and login into the Switch is allowed.  To authenticate a user via SSH public key authentication via SSH public key or the host-based method, the user's public key file or client's host key file must be specified. Both key files have the same format. A key file can contain multiple keys and each key is defined by one line. The maximum length of one line is 8 Kb.  Each key consists of the following space-separated fields: keytype, base64-encoded key, and comment. The keytype and base64-encoded key fields are mandatory and the comment field is optional. The keytype field can be either be ssh-dss or ssh-rsa. Example This example shows how to configure the authentication method to public key for user user1. Switch# configure terminal Switch(config)# ssh user tom authentication-method publickey c:/user1.pub Switch(config)# 421

DGS-1250 Series Gigabit Ethernet Smart Managed Switch CLI Reference Guide
421
Parameters
NAME
Specifies the username to configure the authentication type. The user must be
an existing local account. The length of the username is limited to a maximum of
32 characters.
password
Specifies to use the password authentication method for this user account. This
is the default authentication method.
publickey
URL
Specifies to use the public key authentication method for this user account. Enter
the URL of a local file to be used as the public key of this user.
hostbased
URL
Specifies to use the host-based authentication method for this user account.
Enter the URL of a local file to be used as client’s host key.
host-name
HOSTNAME
Specifies the allowed host name for host-based authentication. During
authentication phase, the client’s hostname will be checked. The range is from 1
to 255.
IP-ADDRESS
(Optional) Specifies whether to additionally check the IP address of the client for
host-based authentication. If not specified, only the host name will be checked.
IPV6-ADDRESS
(Optional) Specifies whether to additionally check the IPv6 address of the client
for host-based authentication. If not specified, only the host name will be
checked.
Default
The default authentication method for a user is
password
.
Command Mode
Global Configuration Mode.
Usage Guideline
The administrator can use this command to specify authentication method for a user. The user name must be a
user created by the username command. By default, the authentication method is password. The system will
prompt the user to input the password.
To authenticate a user via SSH publ
ic key authentication, copy the user’s public key file to file system. When the
user tries to login to the Switch via an SSH client (using the SSH public key method), the SSH client will
automatically transmit the public key and signature with the private key to the Switch. If both the public key and
signature are correct, the user is authenticated and login into the Switch is allowed.
To authenticate a user via SSH public key authentication via SSH public key or the host-based method, the
user’s public key
file or client’s host key file must be specified. Both key files have the same format. A key
file can contain multiple keys and each key is defined by one line. The maximum length of one line is 8 Kb.
Each key consists of the following space-separated fields:
keytype
,
base64-encoded key
, and
comment
.
The
keytype
and
base64-encoded key
fields are mandatory and the
comment
field is optional. The
keytype
field can be either be
ssh-dss
or
ssh-rsa
.
Example
This example shows how to configure the authentication method to public key for user user1.
Switch# configure terminal
Switch(config)# ssh user tom authentication-method publickey c:/user1.pub
Switch(config)#
