IPアドレス取得

VMware PowerCLIを使って ManagementネットワークかからIPアドレスの情報を抜き出して表示させる。

Managementネットワーク情報取得

IPアドレス取得

下記の画面に表示されるIPv4とIPv6に関する情報を取得する。

f:id:pocket01:20191211110041p:plain

■IPv4

PS C:\tmp\a> Get-VMHostNetworkAdapter -VMKernel | select Name, DhcpEnabled,IP, SubnetMask | Format-List

f:id:pocket01:20191211200800p:plain

■IPv6

PS C:\tmp\a> Get-VMHostNetworkAdapter -VMKernel | select Name, IPv6Enabled,IPv6,IPv6ThroughDhcp | Format-List

f:id:pocket01:20191211200708p:plain

■gateway

PS C:\tmp\a> Get-VMHostNetwork | 
select @{N = 'IPv4ゲートウェイ '; E = { if ($null -eq $_.VMKernelGateway) { '---'} else { $_.VMKernelGateway } } },
 @{N = 'IPv6ゲートウェイ '; E = { if ($null -eq $_.VMKernelV6Gateway) { '---'} else { $_.VMKernelV6Gateway } } } | Format-List

DNS/ホスト名の取得

■DNS/ホスト名

$VMHost_Network=Get-VMHostNetwork

Write-Host "ホスト名`t`t`t:" $VMHost_Network.HostName
Write-Host "ドメイン名`t`t`t:" $VMHost_Network.DomainName
Write-Host "検索ドメイン名`t`t:" $VMHost_Network.SearchDomain
Write-Host "DNSサーバ`t`t`t:" $VMHost_Network.DnsAddress

表示のレイアウト修正

情報取得用スクリプト

selectで表示させると空行が多いので表示を Write-Hostで出力させるように修正する。

$VMHost_NetworkAdapter = Get-VMHostNetworkAdapter -VMKernel
$VMHost_Network = Get-VMHostNetwork

Write-Host ""

for ($i=0; $i -lt $VMHost_NetworkAdapter.Length; $i++) {
