前面的文章中曾經(jīng)發(fā)布了對(duì)指定IP進(jìn)行批量端口掃描的方法和腳本，過(guò)PowerShell收發(fā)TCP和UDP消息包的方法以及通過(guò)PowerShell嘗試登錄SQLServer服務(wù)的方法，這構(gòu)成了PSNet程序集用于通過(guò)PowerShell對(duì)網(wǎng)絡(luò)狀態(tài)進(jìn)行操作。最近在不斷嘗試之下，找到了對(duì)指定范圍的IP段進(jìn)行掃描和對(duì)端口進(jìn)行掃描的方法，本文將會(huì)介紹如何通過(guò)PowerShell批量掃描IP及其對(duì)應(yīng)的端口。
依然在PSNet程序集的基礎(chǔ)上進(jìn)行擴(kuò)展，首先在$env:PSSpace/PSNet/TCPOp下創(chuàng)建腳本文件Invoke-ScanIPPort.ps1，并在$env:PSSpace/PSNet/TCPOp/PSNet.psm1中添加對(duì)腳本文件的調(diào)用：
. $env:PSSpace/PSNet/TCPOp/Invoke-ScanIPPort.ps1
首先對(duì)后面代碼中將會(huì)出現(xiàn)的變量進(jìn)行介紹：
-StartAddress[掃描的起始IP地址]，與-EndAddress配合使用，【此參數(shù)必須】
-EndAddress[掃描的結(jié)束IP地址]，【此參數(shù)必須】
-ResolveHost[是否嘗試對(duì)主機(jī)名嘗試進(jìn)行解析]
-ScanPort[是否進(jìn)行端口掃描]，如果要掃描端口此選項(xiàng)必須
-AllPort[是否對(duì)所有端口進(jìn)行掃描]，范圍為1~65534(注意此選項(xiàng)掃描時(shí)間很長(zhǎng)建議在選中單個(gè)IP的情況下進(jìn)行使用，并且盡量少使用)
-StartPort[掃描的起始端口端口]，與-EndPort配合使用，如果此選項(xiàng)與-Ports選項(xiàng)同時(shí)存在則-Port參數(shù)失效
-EndPort[掃描的結(jié)束端口]
-Ports掃描時(shí)默認(rèn)掃描的端口，如果后續(xù)不帶參數(shù)則僅掃描21,22,23,53,69,71,80,98,110,139,111,389,443,445,1080,1433,2001,2049,
3001,3128,5222,6667,6868,7777,7878,8080,1521,3306,3389,5801,5900,5555,5901如果后續(xù)帶多個(gè)以逗號(hào)分割的多個(gè)數(shù)字則會(huì)掃描數(shù)字對(duì)應(yīng)的端口，如果只掃描默認(rèn)的端口，則不需此參數(shù)
-TimeOut超時(shí)時(shí)間，默認(rèn)值為100ms(毫秒)
此函數(shù)的調(diào)用方式如下：
Invoke-ScanIPPort -StartAddress 192.168.10.1 -EndAddress 192.168.10.254#掃描IP段
Invoke-ScanIPPort -StartAddress 192.168.10.1 -EndAddress 192.168.10.254 –ResolveHost#掃描IP段，并嘗試解析IP對(duì)應(yīng)主機(jī)名
Invoke-ScanIPPort -StartAddress 192.168.10.1 -EndAddress 192.168.10.254 -ResolveHost –ScanPort#掃描IP段，并嘗試掃描默認(rèn)端口
Invoke-ScanIPPort -StartAddress 192.168.10.1 -EndAddress 192.168.10.254 -ResolveHost -ScanPort -TimeOut 50 #掃描IP段，嘗試掃描默認(rèn)端口，端口掃描50ms超時(shí)
Invoke-ScanIPPort -StartAddress 192.168.10.1 -EndAddress 192.168.10.254 -ResolveHost -ScanPort -Port 80 #掃描IP段，并嘗試掃描80端口
Invoke-ScanIPPort -StartAddress 192.168.10.1 -EndAddress 192.168.10.1 -ResolveHost -ScanPort –AllPort#掃描ip，并嘗試掃描所有1~65534之間端口
Invoke-ScanIPPort -StartAddress 192.168.10.1 -EndAddress 192.168.10.254 -ScanPort -StarPort 21 -EndPort 81#掃描IP段之間主機(jī)所有21至81之間的端口
上圖來(lái)一張掃描過(guò)程中的圖片
