Device Information

This module displays basic information about the current device, including the host name, operating system version, and network details (such as IP address and DNS). Users can quickly assess the device's operational status and network configuration through this module.

Viewing Device Information

  1. Logging In to the Database Encryption System using the system administrator sysadmin account.
  2. Select System Management > Device Information in the left navigation tree.
  3. View the device information. Device information parameters are explained as shown below.

    Parameter

    Description

    Host Name

    The device's network host name. localhost.localdomain is the default value, indicating no custom domain is configured. In production environments, it is recommended to use a business-identifiable name, such as app-server-01.

    Network Card x

    Network Card

    Network interface name. 'ens33' is a common naming convention for Ethernet cards in Linux systems (e.g., CentOS 7+). Naming conventions may vary across operating systems (e.g., 'Ethernet' in Windows versus 'eth0' in older Linux versions).

    IP Address

    The IPv4 address bound to the network card. Currently, it is 192.168.2.171, a private address segment (Class C) used for LAN communication.

    Subnet Mask

    The network bits and host bits used to allocate IP addresses. 255.255.255.0 indicates that the first 24 bits are the network address and the last 8 bits are the host address, supporting up to 254 devices on the same subnet.

    Default Gateway

    The device's exit address for accessing external networks (outside this subnet). Typically, this is the LAN port IP address of the router, such as 192.168.2.1. Incorrect configuration may prevent internet access.

    Preferred DNS

    The primary domain name resolution server converts domain names into IP addresses. 114.114.114.114 is the nationally recognized public DNS address; you can also use the company's internal DNS address (e.g., 10.0.0.1).

    DNS2

    Backup DNS resolver. Automatically switch to the secondary server when the primary DNS is unavailable. It is recommended to fill in the alternate DNS of different operators or companies.

    DNS3

    Third backup DNS. Used rarely as a final backup when DNS2 fails; optional. It is recommended to leave it blank or enter 8.8.8.8.
