我有一个用PowerShell编写的脚本连接到VPN 现在我想让它重新连接到VPN,如果它断开连接。我能用现在的东西做到吗?
我是PowerShell的新手,所以请耐心等待。

答案 0 :(得分:1)
您可以将代码包装在这样的函数中:
function Reconnect-VPN {
#Source www.cze.cz
#This script is tested with "Cisco AnyConnect Secure Mobility Client version 3.0.5080"
#Please change following variables
#IP address or host name of cisco vpn
[string]$CiscoVPNHost = "ip address"
[string]$Login = "user"
[string]$Password = "pass"
#Please check if file exists on following paths
[string]$vpncliAbsolutePath = 'C:\Program Files (x86)\Cisco\Cisco AnyConnect Secure Mobility Client\vpncli.exe'
[string]$vpnuiAbsolutePath = 'C:\Program Files (x86)\Cisco\Cisco AnyConnect Secure Mobility Client\vpnui.exe'
#****************************************************************************
#**** Please do not modify code below unless you know what you are doing ****
#****************************************************************************

using System;
using System.Runtime.InteropServices;
public class Win {
[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
public static extern bool SetForegroundWindow(IntPtr hWnd);
}
'@ -ErrorAction Stop
#quickly start VPN
#This function is called later in the code
Function VPNConnect()
{
Start-Process -FilePath $vpncliAbsolutePath -ArgumentList "connect $CiscoVPNHost"
$counter = 0; $h = 0;
while($counter++ -lt 1000 -and $h -eq 0)
{
sleep -m 10
$h = (Get-Process vpncli).MainWindowHandle
}
#if it takes more than 10 seconds then display message
if($h -eq 0){echo "Could not start VPNUI it takes too long."}
else{[void] [Win]::SetForegroundWindow($h)}
}
#Terminate all vpnui processes.
Get-Process | ForEach-Object {if($_.ProcessName.ToLower() -eq "vpnui")
{$Id = $_.Id; Stop-Process $Id; echo "Process vpnui with id: $Id was stopped"}}
#Terminate all vpncli processes.
Get-Process | ForEach-Object {if($_.ProcessName.ToLower() -eq "vpncli")
{$Id = $_.Id; Stop-Process $Id; echo "Process vpncli with id: $Id was stopped"}}
#Disconnect from VPN
echo "Trying to terminate remaining vpn connections"
start-Process -FilePath $vpncliAbsolutePath -ArgumentList 'disconnect' -wait
#Connect to VPN

VPNConnect

try{$x = $host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown")}catch{}
}
然后,选择仅在连接VPN时可以访问的IP地址,并对其进行ping操作。如果ping失败,请运行Reconnect-VPN
功能:
$testIP = "10.10.10.10"
if(-not (Test-Connection $testIP)) {
Reconnect-VPN
}
