HP VPN Firewall Appliances System Management and Maintenance Configuration Guide

{ If a client sends the user's public key information to the server through a digital certificate, the
server must specify the PKI domain for verifying the client certificate. For more information about
configuring a PKI domain, see VPN Configuration Guide. To make sure the authorized SSH
users pass the authentication, the specified PKI domain must have the proper CA certificate.
• If the authentication method is publickey or password-publickey, the command level accessible to
the user is set by the user privilege level command on the user interface. If the authentication
method is password, the command level accessible to the user is authorized by AAA.
• SSH1 does not support SFTP or SCP. For an SSH1 client, you must set the service type to stelnet or
all.
• For an SFTP SSH user, the working folder depends on the authentication method:
{ If the authentication method is password, the working folder is authorized by AAA.
{ If the authentication method is publickey or password-publickey, the working folder is set by
using the ssh user command.
• If you change the authentication mode or public key for an SSH user that has logged in, the change
takes effect only at the next login of the user.
Configuration procedure
To configure an SSH user and specify the service type and authentication method:
Ste
p
Command Remarks
1. Enter system view.
system-view N/A
2. Create an SSH user, and
specify the service type
and authentication
method.
• Create an SSH user, and specify the service type
and authentication method for Stelnet users:
ssh user username service-type stelnet
authentication-type { password | { any |
password-publickey | publickey } assign
{ pki-domain pkiname | publickey keyname } }
• Create an SSH user, and specify the service type
and authentication method for all users, SCP or
SFTP users:
ssh user username service-type { all | scp | sftp }
authentication-type { password | { any |
password-publickey | publickey } assign
{ pki-domain pkiname | publickey keyname }
work-directory directory-name }
Use either command.
Setting the SSH management parameters
The SSH management parameters can be set to improve the security of SSH connections. The SSH
management parameters include:
• Compatibility between the SSH server and SSH1 clients.
• RSA server key pair update interval, applicable to users using SSH1 client.
• SSH user authentication timeout period. This parameter is used to reject a connection if the
authentication for the connection is not completed before the timeout period expires.
• Maximum number of SSH authentication attempts. This parameter is used to prevent malicious
password cracking.
