添加一個例外到try catch

-1

我有一個關於下面的腳本的腳本檢查多個郵件服務器對RBL列表的問題，問題是，一些列表（如hostkarma.junkemailfilter.com）有一定的答案，並不意味着IP實際上被列入黑名單。添加一個例外到try catch

所以我想一個異常加入到try..catch功能，如果hostkarma.junkemailfilter.com用127.0.2.1答案郵件服務器沒有進入$blacklistedOn。

腳本：

Param([string]$IP) 

$statusAlive = "ScriptRes:Host is alive:" 
$statusDead = "ScriptRes:No answer:" 
$statusUnknown  = "ScriptRes:Unknown:" 
$statusNotResolved = "ScriptRes:Unknown host:" 
$statusOk   = "ScriptRes:Ok:" 
$statusBad   = "ScriptRes:Bad:" 
$statusBadContents = "ScriptRes:Bad contents:" 

$reversedIP = ($IP -split '\.')[3..0] -join '.' 

$blacklistServers = @(
    "dnsbl-3.uceprotect.net"; 
    "dnsbl-2.uceprotect.net"; 
    "dnsbl-1.uceprotect.net"; 
    "ix.dnsbl.manitu.net"; 
    "bl.spamcop.net"; 
    "bl.spamcannibal.org"; 
    "b.barracudacentral.org"; 
    "ips.backscatterer.org"; 
    "dnsbl.sorbs.net"; 
    "cbl.abuseat.org"; 
    "all.spamrats.com"; 
    "black.uribl.com"; 
    "multi.surbl.org"; 
    "multi.uribl.com"; 
    "truncate.gbudb.net"; 
    "bl.blocklist.de"; 
    "dnsbl.inps.de"; 
    "bl.mailspike.net"; 
    "bl.spameatingmonkey.net"; 
    "db.wpbl.info"; 
    "dnsbl.justspam.org"; 
    "hostkarma.junkemailfilter.com"; 
    "mail-abuse.blacklist.jippg.org"; 
    "psbl.surriel.com"; 
    "spam.dnsbl.anonmails.de"; 
    "ubl.unsubscore.com"; 
    "cblless.anti-spam.org.cn"; 
    "cblplus.anti-spam.org.cn"; 
    "spam.pedantic.org"; 
    "dev.null.dk"; 
    "blackholes.five-ten-sg.com"; 
    "spamsources.fabel.dk"; 
    "zen.spamhaus.org"; 
    "spamguard.leadmon.net"; 
    "dialups.visi.com"; 
    "dnsbl.kempt.net"; 
    "dnsbl.dronebl.org"; 
    "no-more-funn.moensted.dk"; 
    "relays.bl.kundenserver.de"; 
) 

$blacklistedOn = @() 

foreach ($server in $blacklistServers) { 
    $IPServer = "$reversedIP.$server" 

    try { 
     $null = [System.Net.Dns]::GetHostEntry($IPServer) 
     $blacklistedOn += $server 
    } catch { } 
} 

if ($blacklistedOn.Count -gt 0) { 
    # The IP was blacklisted on one or more servers; send your email here. 
    # $blacklistedOn is an array of the servers that returned positive results. 
    Write-Host "$statusAlive"$blacklistedOn 
} else { 
    Write-Host "$statusDead"$blacklistedOn 
}

什麼樣的JavaScript的是什麼？ – CoderPi

這看起來像某種.NET語言 – birdoftheday

那是我的壞，它的Poweshell腳本，只是有一些JavaScript的麻煩，所以我仍然在我的腦海裏有JavaScritp。 –

目前腳本丟棄無論是通過您的主機查找返回。如果要返回一個特定的響應，您需要將其分配給一個變量，並檢查跳過的地址其實之前將服務器添加到$blacklistedOn：

try { 
    $addr = [Net.Dns]::GetHostEntry($IPServer) 
    if (-not ($server -eq 'hostkarma.junkemailfilter.com' -and $addr.AddressList.IPAddressToString -contains '127.0.2.1')) { 
     $blacklistedOn += $server 
    } 
} catch { }
