Show HN: PingStalker – A a macOS tool for network engineers

PingStalker 是一款全面的 Mac 网络监控工具，提供连接健康和性能的实时洞察。它为关键主机提供**实时 Ping 监控**，由 Cloudflare 提供支持的详细**速度测试**，以及清晰的**接口详情**显示，如 IP 地址和 Wi-Fi 强度。除了基本监控外，PingStalker 还提供**无线网络分析**，显示信号强度和信道使用情况，一个方便的**子网计算器**，以及带有供应商识别的**MAC 地址查找**。高级用户可以利用**Wi-Fi 嗅探/监控模式**，并轻松集成到 Wireshark 中。重要的是，PingStalker 具有强大的**网络日志记录**功能，被动地观察和记录重要的网络事件——从意外的 Ping 到 VLAN 暴露——为主动故障排除提供详细的网络活动记录。

## PingStalker：一款macOS网络诊断工具 PingStalker是一款由一位对基于命令行网络发现和监控感到沮丧的网络工程师开发的macOS实用工具。它使用Swift构建，提供了一个GUI来整合必要的网络工具并可视化网络活动。该工具执行ARP、ICMP、mDNS和DNS扫描来识别设备，显示IP、MAC地址、供应商（带有自定义徽标！），以及开放端口。它具有“实时ping”以进行延迟监控、VLAN检测，并捕获关键网络流量，如DHCP事件和802.1X认证。开发者在解码mDNS流量方面投入了大量精力，以提供清晰、易读的输出。开发者正在寻求网络专业人士对其实用性、潜在的扫描速度/可视化改进以及所需功能的反馈。更多详细信息和屏幕截图请访问[https://pingstalker.com](https://pingstalker.com)。

Live Ping Monitoring

Track critical hosts in real time. See latency, uptime, and response trends instantly — know what’s healthy and what’s not.

Speed Testing

Measure download, upload, and latency with Cloudflare’s edge-powered speed tests, then share results instantly with clients or teammates.

Interface Details

Everything you need to know about your connection — from IP and DHCP to Wi-Fi strength and ISP details — presented clearly, updated in real time.

Wireless Network Analysis

See exactly how your Wi-Fi is performing — live signal strength, channel usage, and nearby networks at a glance.

Subnet Calculator

Plan and calculate networks in seconds — CIDR, masks, and ranges made simple and beautifully visual.

MAC Address Lookup

Instantly look up vendors with a built-in offline OUI database that also flags randomized or locally administered MAC addresses — so you always know what’s real.

Wi-Fi Sniffing/Monitor Mode

Turn your Mac into a Wi-Fi sniffer: choose a channel, hit Start, and we’ll handle monitor mode and open Wireshark for you. Change channels on the fly.

Network Logging

When PingStalker is running, it’s watching your network so you don’t have to. It listens for the chatter that matters — another host pinging you, a trunk port exposing extra VLANs, LLDP/CDP Neighbor information or a flood of DHCP or broadcast traffic. These are just a few of the events PingStalker automatically detects and logs, giving you eyes on everything happening beneath the surface.
