Accessing the server/cluster command line reference
The storage server ships with a comprehensive CLI, documented in the online man pages and the CLI Command Line Reference. You can access the server/cluster CLI through the Server Control (SSC) utility, available for Windows and Linux.
Access the CLI in the following ways:
- Secure Shell (SSH) connection into the server through the SMU
- SSH or Telnet connection directly into the server
- Server Control (SSC) utility, available for Windows and Linux
Using SSH on the SMU
The SMU supports SSH. After logging into the SMU, the SMU can redirect connections directly to the server CLI. This can be useful for two reasons:
- It eliminates the need to assign a server administration IP address to the gigabit interface of the server.
- It enhances the security of the server by isolating administrative access to the private management network.
To SSH into the server using the SMU as a proxy:
Procedure
Connect to the SMU through SSH.
Log in to the SMU as manager.
Select the targeted server from the list that is displayed.
The SMU automatically initiates a connection to the server CLI.When prompted, enter the user name supervisor and the password for the “supervisor” user account.
Using SSH on the server
When connecting to a NAS server/cluster through SSH through the administrative services EVS IP address, log in using the user name supervisor.
Use these steps to connect by SSH to the server.
Procedure
Connect to the server's administrative services DNS name or IP address.
ssh supervisor@server_name_or_IPWhen prompted, enter the "supervisor" user's password.
To SSH into the server
Use these steps to connect by SSH to the server.
Connect to the server's administrative services DNS name or IP address.
ssh supervisor@server_name_or_IPWhen prompted, enter the "supervisor" user's password.
Using Telnet
Telnet is not supported on the NAS server.
Using SSC
The administrator can connect to the server from Windows PCs and from Linux/Unix workstations using SSC, which provides a secure connection using a modified version of the Arcfour cipher for encryption and SHA-1 for authentication.
Use the SSC scripting utility to access the server CLI. The server supports SSC access to its CLI through any administrative IP address. By default, the private management network has an administrative IP address available.
The syntax for SSC: ssc -u user_name -p password host[:port][command]
The following table defines the variables:
| Syntax | Description |
| user_name | User account (typically “supervisor”). |
| password | Password. If none specified, SSC prompts for one. |
| timeout | A timeout (in seconds) for a single-use command. |
| EVS | Specifies a particular EVS (by its numerical EVS ID) as the target for a single-use command. |
| host | The server’s administration IP address or host name. |
| port | If the SSC port number has been changed from its default of 206, the port number configured for SSC must be specified in the command syntax. |
| command | Command to execute. If no command is specified, SSC allows interactive command entry. |
