### ACG rule settings/External → Fence server access

A public IP assigned to the Datafence server allows the server access from outside sources. You can restrict access using the Access Control Group (ACG) and enhance security. To access Datafence through a specific external server, configure ACG rules to allow that server's access. To configure ACG rules:

              Caution

              

If you allow access from an outside source, that path can be exploited for a data breach. Exercise caution and enable external access only when strictly necessary.

  - Add rule: Enter the protocol, source IP address, allowed port, and memo, then click **[Add]**.
  - Delete rule: From the list of entered information, click **[Delete]**.
5. After configuring the settings, click **[OK]**.

### ACG rule settings/Fence environment ↔ Box communication

Mutual communication between the Datafence servers in Datafence and the servers in the box is blocked by default. If you need the servers in the box to communicate its log information or other configuration values, configure ACG rules to allow internal communication.

#### Allow and block external communication

Configure a communication network to manage the data for analysis. A box is by default blocked from the Internet. However, if you need Internet access while configuring its analysis environment, you can temporarily allow external communications and block them afterward to enhance security. To allow or block external communications:

              Caution

              

If you allow external communication, its path can be exploited for a data breach. Exercise caution and restrict allowances for special circumstances.

2. Click the **My Datafence** menu.
3. Click the Datafence tab to configure, and in the data box component, click **[View]** in the list.
4. In the View box details interface, select a NAS from the infrastructure list and click **[Change NAS capacity]**.
5. In the **Edit NAS capacity** popup, enter the new capacity and click **[OK]**.
  - The NAS capacity is updated as entered.

## Access box

The analyst needs to access the box via the received box information to analyze the target data. This guides on how to access the box and how to access the analysis environment within the box.

              Note

              

SSL VPN connection is required before accessing the Box. To connect SSL VPN:

- Install SSL VPN Agent.
  - For more information on how to install the SSL VPN Agent, see [Install SSL VPN Agent](/docs/en/sslvpn-agent-vpc#ssl-vpn-agent-%EC%84%A4%EC%B9%98) in the SSL VPN user guide (VPC).
- Run the BIG-IP Edge Client.
  - For more information on how to access the BIG-IP Edge Client, see [Access SSL VPN Agent](/docs/en/sslvpn-agent-vpc#ssl-vpn-agent-%EC%A0%91%EC%86%8D) in the SSL VPN user guide (VPC).
- Enter the registered username and password and click **[Log on]**.
- Enter the OTP code sent to your mobile phone or email account and click **[Log on]**.

### Access Connect Server

To use Cloud Hadoop, TensorFlow, Linux, and Windows Server installed in the Box, you need to access Connect Server. To this end, this guide describes how to access Connect Server.

1. Because the Connect Server is Windows-based, access it using **Remote Desktop** on your PC.
2. After entering the Connect Server's IP, click **[Connect]** and enter your username and password.

#### Check data storage

All Connect Servers have the NAS mounted in the same folder, and mount location has rules as follows: You can check the NAS name in the View box details interface.

- NAS used for requesting file import or export: C:\mount\NAS name.
- Shared storage NAS: C:\mount\nasr\NAS name.

#### Cautions when using NAS in Connect / Windows Server

When using NAS with Connect Server and Windows Server, there are restrictions due to differences in the operating systems. Review the following precautions before use.

              Caution

              

NAS is currently used with limits in the Connect Server and Windows Server. Thoroughly review the following items before use:

#### Mismatch of character encoding method

NAS provided by Datafence uses an NFS protocol usable for Linux Server. The following issues can occur from the difference between the encoding method used by Linux and Windows Operating System (OS):

- When the file name is created using Korean characters, the file name from each OS appears inaccurately.
  - When a file is created using Korean characters in NAS from Connect/Windows, the file name appears in an unknown format.
  - When a file is created using Korean characters in NAS from Linux, the file name appears in an unknown format in Connect/Windows.
- When the file name is in Korean when importing files, the file name appears in an unknown format in Connect/Windows.
- When a file is exported, the file name that appears in Linux is used as the standard. When the name of the created file is in Korean in Connect/Windows, it appears as an unknown format in Linux so export is impossible.
- The new line difference between Connect/Windows and Linux can cause each file description to appear differently.

#### Actions usable for files and folders

Actions usable for file and folder of NAS in Connect/Windows Server are as follows:

**File**

|  | GUI (file explorer) | Command prompt |
| --- | --- | --- |
| Create | O (unable to specify name) | O |
| Read | O | O |
| Copy | O | O |
| Move | O | O |
| Delete | O | O |
| Edit name | X | O |
| Edit file content | O | - |

**Folder**

|  | GUI (file explorer) | Command prompt |
| --- | --- | --- |
| Create | O (unable to specify name) | O |
| Copy | O | O |
| Move | O | X |
| Delete | O | O |
| Edit name | X | X |

### Use and access Cloud Hadoop

Configuring SSH for Hadoop access on Connect Server requires the following 2 steps:

1. Convert authentication key
2. Access cluster node

#### Convert authentication key

To convert the PEM authentication key issued from Connect Server to the PPK format used by PuTTY:

1. After accessing Connect Server, run **PuTTYgen**.
2. Select **RSA** in **Type of key to generate** and click **[Load]**.
3. In **Users** > **Public** > **Desktop**, select **databox.pem** and click **[Open]**.

- To find a file in PEM format, select the option that allows you to see files of all types.

1. Review the content in the **Completion confirmation** popup and click **[OK]**.
2. Click **[Save private key]** and save it in PPK format so that it can be used in PuTTY.

- If PuTTYgen displays a warning message about saving a key without a password, click **[Yes]**.
- Save it using the same name as the previously generated authentication key. PuTTY automatically adds the .ppk file extension.

#### Access Hadoop node SSH

To connect to a Hadoop cluster node via SSH using PuTTY with the converted PPK authentication key:

1. After accessing Connect Server, run **PuTTY**.
2. Select **Session** in the **Category** popup and enter as below:

- **HostName(or IP address)**: sshuser@HadoopIP
  - You can check Hadoop's IP in the View box details interface.
- **Port**: 22

1. In the **Category** popup, navigate to **Connection** > **SSH** > **Auth** > **Credentials**.
2. In **Private key file for authentication**, click **[Browse]**, select the PPK file converted from the PEM file, and then click **[Open]**.
3. Verify that the connection to Hadoop has been successfully established, as shown in the example below.
