Yahoo!と阿部寛とGoogleに疎通確認するPowerShellスクリプトを作った

疎通確認する PowerShell スクリプトを作ったのでメモする。

9 Linux の疎通確認シェルスクリプトはこちら

機能

・host名出力
・ipconfig出力
・WinHttpプロキシ設定確認
・以下の宛先に対する疎通確認(tnc 443 /tnc 80 / curl)出力
URL_1=yahoo.co.jp Yahoo! JAPAN
URL_2=abehiroshi.la.coocan.jp 阿部寛のホームページ (coocan.jp)
URL_3=google.com Google
*PowerShell において tnc は Test-NetConnection ,curl は Invoke-webRequest のエイリアスなので、それぞれ同じです。
・ファイル出力機能(実行フォルダに AzureBackup_Check_NW_YYYYMMMM_HHMMSS.log が生成されます)

実行方法

右クリック → PowerShellで実行

実行画面

下記のような感じ。阿部寛さんの公式HPがhttpsに対応していないっぽいことが分かる。

zip

Check_NW_Windows+ResultExample.zip
中身
Check_NW_Windows.ps1
CheckNWResult_20220320_204046.log

コード

Check_NW_Windows.ps1

 ####yamapan.tokyo
# Name directory
$static_logName = "CheckNWResult"

#Get Script Located Path
$logDirPath = $PSScriptRoot

# Set log location and filename
$logFilePath = "${logDirPath}\${static_logname}_$($(Get-Date).ToString("yyyyMMdd_HHmmss")).log"

###Target URL setting
$URLs=@()
$URLs+= "yahoo.co.jp"
$URLs+= "abehiroshi.la.coocan.jp"
$URLs+= "google.com"

PowerShell ファイル出力部分

まず、ファイル出力する先を設定する。
下記の例だとスクリプトがあるフォルダに CheckNWResult_YYYYMMDD_HHMMSS.log という命名規則で出力する

# Name directory
$static_logName = "CheckNWResult"
#Get Script Located Path
$logDirPath = $PSScriptRoot
# Set log location and filename
$logFilePath = "${logDirPath}\${static_logname}_$($(Get-Date).ToString("yyyyMMdd_HHmmss")).log"

次にファイル出力する記述を下記のように各

#Start
Transcript Start-Transcript -path "${logFilePath}" -Append
Write-Output "-----ScriptStart----- $(Get-Date)"
#この間に出力したい処理を書く#

#この間に出力したい処理を書く#
Write-Output "-----ScriptStart Completed----- $(Get-Date)"
