KYSDK-NET(8)

💖 KYSDK-NET 💖

okay bestie, welcome to kysdk-net — section 8 of the manual, System Administration Utilities, the whole system-admin vibe. this is the KYLIN SDK Network Information Service and she is, lowkey, the main character of your network stack. let's get into it 🫶

---

✨ NAME ✨

kysdk-net — the KYLIN SDK Network Information Service. yes, that's the whole name, no notes, iconic.

---

🌸 SYNOPSIS 🌸

kysdk-net

that's it. that's the whole invocation. she runs herself, fr fr 💅

---

🦋 DESCRIPTION 🦋

so kysdk-net is a network information service daemon living inside the KYLIN SDK system. she is not here to be shy — she provides comprehensive network information query functionality, which is a fancy way of saying she collects and manages all your network-related data: port status, routing information, firewall rules, network connections, and DNS configuration. the whole little ecosystem. 🌈

and how does she share all this? through a D-Bus interface, babes. the service name is com.kylin.kysdk.Net, so any other application that wants to know what's going on with your network can just slide into her D-Bus DMs and get the info through D-Bus calls. no cap. ✨

---

👑 FEATURES 👑

here's the menu, and yes, she ate:

• Port Status Monitoring — provides TCP/UDP port status query functionality, including specific port status and port range status queries. so you can ask about one port or a whole little squad of ports. 🎀
• Routing Information Retrieval — obtains system routing table information, and especially the default gateway information, which is the one everybody actually wants. iykyk. 🛣️
• Firewall Rule Query — retrieves firewall chain and rule information through iptables. the bouncer of your network, and she's got the guest list. 🔥
• Network Process Association — obtains information about processes occupying network ports. so when something's squatting on a port you can find out who did it. 💀
• Network Configuration Query — retrieves network configuration information such as the hosts file and resolv.conf. the classics. 🍓
• Network Interface Detection — detects network link types (Ethernet/WiFi), link status, etc. the etc. is doing a lot of work there but we respect it. 🌸
• WiFi Information Retrieval — obtains wireless network interface information including operating mode, frequency, channel, and rate. all the wifi lore. 📡
• DHCP Configuration Query — retrieves IPv4 and IPv6 DHCP configuration information. both of them. equal treatment. periodt. 💜

⭐ FUNCTIONS ⭐

here come the function signatures, bestie. copy them exactly, do not freestyle, do not "fix" them, she's sensitive:

• kdk_net_get_port_stat(int port) — retrieves status information for the specified port number.
• kdk_net_get_multiple_port_stat(int start, int end, int *result) — retrieves status information for the specified port range. give her a start, give her an end, she fills in result. 🫶
• kdk_net_get_route() — retrieves routing table information.
• kdk_net_get_iptable_rules() — retrieves iptables firewall rules.
• kdk_net_get_proc_port() — retrieves network port to process association information.
• kdk_net_get_up_port() — retrieves list of ports in listening state.
• kdk_net_get_hosts() — retrieves hosts file content.
• kdk_net_get_resolv_conf() — retrieves DNS resolution configuration.
• kdk_net_get_link_type() — retrieves network link type.
• kdk_net_get_link_status(char *ip, char *port) — checks connection status with specified IP and port. yes you hand her an ip and a port and she tells you if it's giving connected. 🔌
• kdk_net_get_wifi_*() — retrieves various WiFi-related information (mode, frequency, channel, rate, etc.). the little * is the whole wifi department, okay. 📶
• kdk_net_get_ipv4_dhcp_config() — retrieves IPv4 DHCP configuration information.
• kdk_net_get_ipv6_dhcp_config() — retrieves IPv6 DHCP configuration information.

🎀 FILES 🎀

where she lives, literally:

• /usr/bin/kysdk-net — executable file path. that's her. that's the girl. 💖
• /etc/systemd/system/kysdk-net.service — systemd service configuration file.

---

🧚 SERVICE 🧚

so this tool runs as a systemd service with the service file kysdk-net.service, and she communicates through the D-Bus interface with service name com.kylin.kysdk.Net. she's not a one-off command you poke at, she's a whole service. main character energy, constantly running, always available. 💅

---

🌈 D-BUS INTERFACE 🌈

the service provides the following interfaces through D-Bus:

• getFirewallState: retrieve firewall status
• getProcPort: retrieve process port information

those two. that's the list. short but mighty. ✨
