> listen
> This command configures the SSH server in the current context to only listen for connections from the interface with the specified IP address. The default behavior is to listen on all interfaces.
> Product
> All
> Privilege
> Security Administrator, Administrator
> Syntax
> listen ip_address
> no listen
> no
> Disable listening for a specific interface address and enable listening on all interfaces.
> Usage
> Use this command to configure the SSH server for the current context to only listen for connections from the interface with the specified IP address. Only one IP address may be set for listening.
> Example
> The following command specifies that the Server should only listen for connections in the interface with the IP address of 192.168.0.10:
> listen 192.168.0.10
> max servers
> Configures the maximum number of SSH servers that can be started within any 60 second interval. If this limit is reached, the system waits two minutes before trying to start any more servers.
> Product
> All
> Privilege
> Security Administrator, Administrator
> Syntax
> max servers number
> number
> Default: 40
> Specifies the maximum number of servers that can be spawned in any 60 second interval. number must be a value in the range from 1 to 100.
> Usage
> Set the number of servers to tune the system response as a heavily loaded system may need more servers to support the incoming requests.
> The converse would be true as well in that a system can benefit by reducing the number of servers such that telnet services do not cause excessive system impact to other services.
> Example
> max servers 50
> subsystem
> Configures the system to perform file transfers using secure ftp (sftp) over ssh v2. Administrator users must be configured with the ftp attribute privilege to issue this command.
> Product
> All
> Privilege
> Security Administrator, Administrator
> Syntax
> subsystem { cli | sftp }
> no subsystem { cli | sftp }
> no
> Disables either the sftp ssh file transfer method or disables access to the CLI over ssh.
> cli
> Default: Enabled
> Configures the SSH system for the current context to allow access to the CLI.
> sftp
> Default: Disabled
> Enables the SSH system for the current context to perform file transfers using secure ftp (sftp) over ssh v2.
> Usage
> Use this command to enable or disable file transfers using secure ftp over an ssh v2 tunnel.
> Also use this command to enable or disable access to the CLI over an SSH connection.
> Example
> The following command enables SFTP for the current context:
> subsystem sftp
> The following command disables access to the CLI through an SSH session for the current context:
> no subsystem cli
