准备工作

将网线接入以太网口，接通电源，等待以太网口指示灯稳定闪烁。

专业快速开始

打开cmd或pwsh输入ssh root@<局域网设备IP> 后输入密码lynx即可，比如

ssh root@192.168.88.201

查看设备局域网IP地址

在与设备相同局域网下的本地电脑中打开Powershell执行以下指令，复制后粘贴回车运行等待返回结果。

# ===== 1. 自动获取本机活动网卡及 IPv4 =====
$nic = Get-NetIPConfiguration |
       Where-Object { $_.IPv4DefaultGateway -and $_.NetAdapter.Status -eq 'Up' } |
       Select-Object -First 1

if (-not $nic) { Write-Error "未找到带默认网关的活动网卡"; exit 1 }

$localIp = $nic.IPv4Address.IPAddress
Write-Host "本机网卡: $($nic.InterfaceAlias) | IP: $localIp" -ForegroundColor Cyan

# ===== 2. 自动推算所在 /24 网段 =====
$base = ($localIp -split '\.')[0..2] -join '.'
Write-Host "扫描网段: $base.0/24 ..." -ForegroundColor Cyan

# ===== 3. 并发 Ping 扫描 + 反向解析主机名 =====
$online = 1..254 | ForEach-Object -Parallel {
    $target = "$using:base.$_"
    if (Test-Connection -ComputerName $target -Count 1 -TimeoutSeconds 1 -Quiet) {
        $name = $null
        try { $name = ([System.Net.Dns]::GetHostEntry($target)).HostName } catch {}
        [PSCustomObject]@{ IP = $target; HostName = $name }
    }
} -ThrottleLimit 128

# ===== 4. 用 ARP 表补全 MAC 地址 =====
$arp = @{}
if (Get-Command Get-NetNeighbor -ErrorAction SilentlyContinue) {
    # Windows
    Get-NetNeighbor -AddressFamily IPv4 -State Reachable, Stale -ErrorAction SilentlyContinue |
        ForEach-Object { $arp[$_.IPAddress] = $_.LinkLayerAddress }
} else {

    (arp -a 2>$null) | ForEach-Object {
        if ($_ -match '^\s*([\d\.]+)\s+[\w:-]+\s+([\da-fA-F:.-]+)') { $arp[$matches[1]] = $matches[2] }
    }
}

# ===== 5. 输出结果 =====
$result = $online | Sort-Object { [int]($_.IP -split '\.' | Select-Object -Last 1) } | ForEach-Object {
    [PSCustomObject]@{
        IP       = $_.IP
        HostName = if ($_.HostName) { $_.HostName } else { '-' }
        MAC      = if ($arp.ContainsKey($_.IP)) { $arp[$_.IP] } else { '-' }
    }
}

从扫描结果中找到设备IP

图上的orangepizero.lan就是设备，其ip为192.168.88.201

或者可以通过路由器后台看到设备所连IP，还可以通过Angry IP Scanner等工具获取设备IP
