Secure Shell Server Configuration - NEC N8406-022A Reference Manual

Secure Shell Server configuration

Command: /cfg/sys/sshd
[SSHD Menu]
Telnet traffic on the network is not secure. This menu enables Secure Shell (SSH) access from any SSH client. The
SSH program securely logs into another computer over a network and executes commands in a secure
environment. All data using SSH is encrypted.
Secure Shell can be configured on the switch using the console port only. The menu options do not display if you
access the switch using Telnet or the Browser-based Interface (BBI).
NOTE: See the Application Guide for information on SSH.
The following table describes the SSHD Configuration Menu options.

Description
Defines interval for auto-generating the RSA server key. The switch will
auto-generate the RSA server key at the interval defined in this
command. The value of zero (0) means the RSA server key auto-
generation is disabled. If the switch has been busy performing any other
key generation and the assigned time of interval expires, the RSA
server will skip generating the key.
Defines the administrator password that is for Secure Copy (SCP) only.
The username for this SCP administrator is scpadmin.
Typically, SCP is used to copy files securely from one machine to
another. In the switch, SCP is used to download and upload the switch
configuration using secure channels.
Generates the RSA host keys manually. The switch creates this key
automatically while configuring the switch with Secure Shell (SSH). But
you can generate the key manually by using this command if you need
to overwrite the key for security reasons. The command will take effect
immediately without executing the apply command.

Sets the SSH server port number. The default is 22.
Enables the SCP apply and save.
Disables the SCP apply and save. This is the default for SCP.
Enables the SSH server.
Disables the SSH server. This is the default for the SSH server.
Displays the current SSH server configuration.
