NAME
       kysdk-net - KYLIN SDK Network Information Service


SYNOPSIS
       kysdk-net


DESCRIPTION
       kysdk-net is a network information service daemon in the KYLIN SDK
       system. This service provides comprehensive network information query
       functionality, including collection and management of network-related
       data such as port status, routing information, firewall rules, network
       connections, and DNS configuration.

       The service provides its functionality through a D-Bus interface with
       the service name `com.kylin.kysdk.Net`, allowing other applications to
       obtain system network information through D-Bus calls.


FEATURES
       Port Status Monitoring
              Provides TCP/UDP port status query functionality, including
              specific port status and port range status queries

       Routing Information Retrieval
              Obtains system routing table information, particularly default
              gateway information

       Firewall Rule Query
              Retrieves firewall chain and rule information through iptables

       Network Process Association
              Obtains information about processes occupying network ports

       Network Configuration Query
              Retrieves network configuration information such as hosts file
              and resolv.conf

       Network Interface Detection
              Detects network link types (Ethernet/WiFi), link status, etc.

       WiFi Information Retrieval
              Obtains wireless network interface information including
              operating mode, frequency, channel, and rate
