Show HN: PingStalker – 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：macOS网络工具简介 PingStalker是一款为网络工程师和专业人士开发的macOS工具，提供了一个基于GUI的网络诊断替代方案，取代了命令行界面。这款工具的创建者是一位对CLI局限性感到沮丧的Wi-Fi工程师，旨在提供对局域网/无线局域网网络活动的全面、实时视图。该工具执行ARP、ICMP、mDNS和DNS扫描，以识别设备、监控延迟、检测VLAN以及捕获关键网络流量，例如DHCP事件和身份验证数据。一个独特的功能是自定义厂商logo数据库，可在扫描结果中直观地识别设备。PingStalker使用Swift构建，并同时利用BSD sockets和Apple的网络框架，优先考虑速度和可靠性。开发者正在积极寻求关于潜在改进的反馈，包括移植到Linux/BSD、扫描速度优化和可视化增强。未来的计划包括iOS、Android和Windows版本，以及视觉traceroute和扩展的Wi-Fi分析功能。目前，它可直接从开发者的网站下载，并提供为期一天的试用期。

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.
