Chapter 12: Secure Shell Server (SSH) Commands

SSH DISABLE
Syntax
ssh disable
Parameters
None.
Privilege Levels
Administrator and read-write
Description
This command is used to disable the SSH server on the management
module. This is the default setting for the server. When the server is
disabled, you can not manage the unit remotely from an SSH client. You
should leave the server disabled if you will not be managing the unit with
an SSH client, to protect the management module from unauthorized
access.
Note
If you disable the server during a remote SSH management session,
the session is automatically logged out. To continue managing the
unit, start a local management session on the unit or a remote
Telnet session.
Example
ssh disable
