Renaming all file names in a directory with Powershell

admin — Sun, 27 Jun 2010 18:46:44 +0000

If you use Flashget, sometimes it downloads files with .html extension. You have to trim .html extensions from files but if you download so many files, you need to use script to save your time.

$files = dir
foreach ($file in $files)
{
$new=$file.name.replace(".html","")
ren $file $new
}

Simply, I use basic dos command, ren to rename files. But you can use Rename-Item to make it 100% Powershell :)

Getting Dell servers hardware specification with Powershell

admin — Thu, 17 Jun 2010 09:32:02 +0000

One of my colleague asked me to make a script to write out server specifications of our new Dell servers using with their Service Tags. Recently, We rented more than 200 Dell servers and that is real mess to know which one has 4 gb ram and which one has SAS raid etc. The quickiest way to know this, using their Service Tags. Because you can see servers hardware from Dell web page with Service Tags. My script simply use service tags to get hardware and parse it for a more readable format.

'$HardDriveModel=$Matches[6]$HardDriveModel=$HardDriveModel.Replace(" ","")$HardDriveModel=$HardDriveModel.Replace("

$ServiceTags = Get-Content C:\ServiceTags.txt
$TagsDir = "C:\ServiceTags"
Foreach ($ServiceTag in $ServiceTags)
{
$SystemInfoURL = "http://support.dell.com/support/topics/global.aspx/support/my_systems_info/en/details?c=us&l=en&s=gen&servicetag=" + $ServiceTag + "&~tab=2&~wsf=tabs"
$Webclient = New-Object System.Net.WebClient
$Webpage = $Webclient.DownloadString($SystemInfoURL)
$Webpage > "$TagsDir\$ServiceTag.txt"
 
$HardDrive = Select-String "$TagsDir\$ServiceTag.txt" -Pattern 'Hard Drive'
$HardDrive = "$HardDrive" -match '

([^"]+)

Hard Drive,(.*?),([^"]+)

","") $HardDriveCount = $Matches[2] $HardDriveSize = $Matches[5] $Processor = Select-String "$TagsDir\$ServiceTag.txt" -Pattern 'Processor' $Processor = "$Processor" -match '([^"]+)Processor,(.*?),([^"]+)' $ProcessorModel = $Matches[6] $ProcessorModel = $ProcessorModel.Replace(" ","") $ProcessorModel = $ProcessorModel.Replace("","") $ProcessorCount = $Matches[2] $ProcessorSize = $Matches[5] $Memory = Select-String "$TagsDir\$ServiceTag.txt" -Pattern 'Memory' $Memory = "$Memory" -match '([^"]+)Dual In-line Memory Module,(.*?),([^"]+)' $MemoryModel = $Matches[6] $MemoryModel = $MemoryModel.Replace(" ","") $MemoryModel = $MemoryModel.Replace("","") $MemoryCount = $Matches[2] $MemorySize = $Matches[5] $Raid = Select-String "$TagsDir\$ServiceTag.txt" -Pattern 'Assembly' $Raid = "$Raid" -match '([^"]+)Assembly,Cable,(.*?),([^"]+)' $RaidModel = $Matches[5] $RaidModel = $RaidModel.Replace(" ","") $RaidModel = $RaidModel.Replace("","") $RaidCount = $Matches[2] $RaidType = $Matches[6] Write-Host Service Tag: $ServiceTag -ForegroundColor Red Write-Host Hard Drive: -ForegroundColor Green write-host Adet: $HardDriveCount write-host Kapasite: $HardDriveSize write-host Model: $HardDriveModel Write-Host Processor: -ForegroundColor Green write-host Adet: $ProcessorCount write-host Kapasite: $ProcessorSize write-host Model: $ProcessorModel Write-Host Memory: -ForegroundColor Green write-host Adet: $MemoryCount write-host Kapasite: $MemorySize write-host Model: $MemoryModel Write-Host Raid: -ForegroundColor Green write-host Adet: $RaidCount write-host Tip: $RaidType write-host Model: $RaidModel write-host }

You can use Add-Content to print them to txt files.

Exchange Server 2010′dan default mailbox’ı kaldırmak

admin — Wed, 05 May 2010 16:59:08 +0000

Exchange Server 2010 kurulumu sonrası gelen default mailbox’ı, içinde sistem mailbox’ı barındırdığı için EMC üzerinden Remove edemezsiniz. Bunun için Powershell üzerinden aşağıdaki adımları uygulamanız gerekiyor.

Öncelikle gizli sistem mailbox’larını görüntüleyelim:

Get-Mailbox -Arbitration

Sonra aşağıdaki komut ile bu mailbox’ları yeni database’e taşıyalım:

Get-Mailbox -Arbitration | New-MoveRequest -TargetDatabase “Yeni_Database”

Yukardaki komut sonrası bu mailbox’lar taşınmaya başlarlar. Taşınma durumunu aşağıdaki komut ile görebilirsiniz.

Get-MoveRequest

Eğer mailbox’ların taşınma işlemi için completed deniliyorsa, aşağıdaki komut ile bu mailbox’ların MoveRequest’lerini kaldırabilirsiniz.

Get-MoveRequest | Remove-MoveRequest

Bu işlemler sonrasında artık EMC üzerinden eski database’i kaldırmanız mümkün durumdadır.

Exchange Server 2010 için örnek CSR başvurusu

admin — Tue, 04 May 2010 21:00:28 +0000

Yapınızda birden fazla Exchange Server 2010 var ise aşağıdaki gibi csr başvurusu yapabilir ve aynı SSL’i birden fazla sunucu üzerinde tutabilirsiniz.

New-ExchangeCertificate -FriendlyName 'exchange.radore.net' -GenerateRequest -PrivateKeyExportable $true -KeySize '2048' -SubjectName 'C=TR,S="Metrocity",L="Istanbul",O="Radore Hosting",OU="IT",CN=exchange.radore.net' -DomainName 'exchange.radore.net','autodiscover.rh.com.tr','autodiscover.rh.net.tr','EXCAS','MAILBOX','EXC2010' -Server 'EXCAS'

Sertifikanın complete işlemini Exchange arabirimi üzerinden yapabilirsiniz.

Exchange Server 2007′den Disconnected Mailbox’ların kaldırılması

admin — Tue, 27 Apr 2010 19:05:44 +0000

Exchange 2007′den mailbox sildiğinizde, bu mailbox disconnected mailbox’lar altında görünmeye devam eder. Mailbox’ın kullanıcısını ise başka bir mailbox ekleyemezsiniz bu durumda. Bu yüzden disconnected mailbox’ı kaldırmalı ve kullanıcıyı boşa çıkarmalıyız. Bu işlemi de Powershell üzerinden yapabilmekteyiz. Aşağıda Powershell v1 ve v2 kodlarını bulabilirsiniz.

Powershell v1:

Get-MailboxStatistics | where-object { $_.DisconnectDate -ne $null } | Select DisplayName,MailboxGuid

Powershell v2:

Get-MailboxStatistics -Database "DBName" | where-object { $_.DisconnectDate -ne $null } | Select DisplayName,MailboxGuid

Yukardan MailboxGuid’i aldıktan sonra aşağıdaki komut ile silme işlemini gerçekleştirebilirsiniz.

Remove-Mailbox -Database <Database-Name> -StoreMailboxIdentity <MailboxGuid> -confirm:$false

Bu işlem sonrası kullanıcınıza sıfır bir mailbox bağlayabilirsiniz.

Calculating daily bandwidth usage of websites on IIS7.5 with Powershell

admin — Sun, 18 Apr 2010 09:05:43 +0000

First, you need IIS Log Parser 2.2 to parse log files and calculate daily usage. Then we will get list of websites with Powershell and write bandwidth usages into a file.

Download IIS Log Parser v2.2:

http://www.microsoft.com/downloads/details.aspx?FamilyID=890cd06b-abf8-4c25-91b2-f8d975cf8c07

Install IIS Log Parser v2.2. I created a new directory in drive D called LogParser and copied 2 files (logparser.dll and logparser.exe) into that directory. Now let’s see Powershell codes how to use LogParser v2.2 with Powershell.

Import-Module WebAdministration
Websites = Get-Website *
Foreach ($i in $Websites)
{
$Name = $i.Name
$ID = $i.ID
$PhysicalPath = $i.PhysicalPath
$Date = (Get-Date).AddDays(-1).ToString("yyMMdd") + '.log'
$Bandwidth = &'D:\tools\LogParser\LogParser.exe' "Select Div(Sum(sc-bytes),1048576) As Bandwidth From '$PhysicalPath\W3SVC$ID\u_ex$Date'" -q:ON
$Value = "$Name : $Bandwidth"
Add-Content -Path Bandwidth.txt -Value $Value
}

You see how easy it is? But this is just an example. I don’t care about Log Path. You should edit path for your own environment. Have fun!

Powershell Türkiye Kullanıcıları Grubu Facebook Sayfası

admin — Tue, 13 Apr 2010 18:35:22 +0000

Türkiye’deki Powershell kullanıcılarını bir araya getirmeyi amaçlıyorum. Böylece beyin fırtınası yaratarak, daha iyi projeler çıkarabiliriz ortaya. Her ne kadar Powershell kullanıcısı şuan için az olsa da (Türkiye’de), yapacağım seminer ve webinerler ile Powershell kullanımını arttırmaya çalışacağım.

Şuan kişisel sitem yusufozturk.info’da 100′ün üzerinde Powershell yazısı bulunmakta. Bunların arasında yeni başlayan kullanıcılara hitaben yazılmış yazılar da var, ileri seviye kullanıcılara göre yazılar da.. Umarım bu sene sonunda bu sayıyı 200′e çıkartabilirim.

Facebook grubuna aşağıdaki bağlantıdan üye olabilirsiniz:

http://www.facebook.com/group.php?gid=105220719519853

Bundan sonraki Powershell yazılarını http://www.write-host.com üzerinden yayınlamaya çalışacağım.

Tüm sistem uzmanları ve sistem ile uğraşan öğrencileri gruba beklerim.

Creating New FTP User on Active Directory with Powershell

admin — Tue, 02 Mar 2010 09:43:27 +0000

Creates a new user on Active Directory and sets “Password never expires”

Function Add-FTPUser
{
Param ($FTPUsername, $FTPPassword)
 
    $ADDomain = [System.DirectoryServices.ActiveDirectory.Domain]::GetCurrentDomain()
    $ADDomainName = $ADDomain.Name
    $ADServer = ($ADDomain.InfrastructureRoleOwner.Name.Split(".")[0])
    $FQDN = "DC=" + $ADDomain.Name -Replace("\.",",DC=")
    $ADDomain = [ADSI] "LDAP://$ADServer/$FQDN"
    $CustomerOU = [ADSI] "LDAP://$CustomerOU,$FQDN"
    $User = [ADSI] "LDAP://CN=$FTPUsername,$CustomerOU,$FQDN"
    $PrincipalName = $FTPUsername + "@" + $ADDomainName
    $AddADUser = $CustomerOU.Create("User","CN=$FTPUsername")
    $AddADUser.Put("Description", "$FTPUsername")
    $AddADUser.Put("sAMAccountName", "$FTPUsername")
    $AddADUser.Put("userPrincipalName", "$PrincipalName")
    $AddADUser.Put("DisplayName", "$FTPUsername")
    $AddADUser.SetInfo()
    $AddADUser.SetPassword($FTPPassword)
    $AddADUser.SetInfo()
    $AddADUser.Psbase.Invokeset("AccountDisabled", "False")
    $AddADUser.SetInfo()
    $AddADUser.Put("userAccountControl", "65536")
    $AddADUser.SetInfo()
}

I didn’t change Primary Group of my FTP user. Because I don’t need for ACL.

Creating New IIS User on Active Directory with Powershell

admin — Tue, 02 Mar 2010 09:40:02 +0000

Creates a new user on Active Directory, sets “Password never expires” and changes primary group of user.

Function Add-IISUser
{
Param ($Username, $Password)
 
    $ADDomain = [System.DirectoryServices.ActiveDirectory.Domain]::GetCurrentDomain()
    $ADDomainName = $ADDomain.Name
    $ADServer = ($ADDomain.InfrastructureRoleOwner.Name.Split(".")[0])
    $FQDN = "DC=" + $ADDomain.Name -Replace("\.",",DC=")
    $ADDomain = [ADSI] "LDAP://$ADServer/$FQDN"
    $CustomerOU = [ADSI] "LDAP://$CustomerOU,$FQDN"
    $User = [ADSI] "LDAP://CN=$Username,$CustomerOU,$FQDN"
    $PrincipalName = $Username + "@" + $ADDomainName
    $AddADUser = $CustomerOU.Create("User","CN=$Username")
    $AddADUser.Put("Description", "$Username")
    $AddADUser.Put("sAMAccountName", "$Username")
    $AddADUser.Put("userPrincipalName", "$PrincipalName")
    $AddADUser.Put("DisplayName", "$Username")
    $AddADUser.SetInfo()
    $AddADUser.SetPassword($Password)
    $AddADUser.SetInfo()
    $AddADUser.Psbase.Invokeset("AccountDisabled", "False")
    $AddADUser.SetInfo()
    $AddADUser.Put("userAccountControl", "65536")
    $AddADUser.SetInfo()
    $DomainNC = ([ADSI]"LDAP://RootDSE").DefaultNamingContext
    $DomainUsers = [ADSI]"LDAP://CN=Domain Users,CN=Users,$DomainNC"
    $DomainUsers.GetInfoEx(@("primaryGroupToken"), 0)
    $OldGroupToken = $DomainUsers.Get("primaryGroupToken")
    $DomainGuests = [ADSI]"LDAP://CN=IIS_USERS,CN=Users,$DomainNC"
    $DomainGuests.GetInfoEx(@("primaryGroupToken"), 0)
    $NewGroupToken = $DomainGuests.Get("primaryGroupToken")
    $DomainGuests.Add([String]($AddADUser.AdsPath))
    $AddADUser.Put("primaryGroupId", $NewGroupToken)
    $AddADUser.SetInfo()
    $DomainUsers.Remove([String]($AddADUser.AdsPath))
}

Our new Primary Group is IIS_USERS as you see. You can change that group name.

Getting Active Directory Information with Powershell

admin — Tue, 02 Mar 2010 09:35:28 +0000

My script works on all Active Directory Infrastructures without any change on script.

Function Get-ADInfo
{
    $ADDomain = [System.DirectoryServices.ActiveDirectory.Domain]::GetCurrentDomain()
    $ADDomainName = $ADDomain.Name
    $Netbios = $ADDomain.Name.Split(".")[0].ToUpper()
    $ADServer = ($ADDomain.InfrastructureRoleOwner.Name.Split(".")[0])
    $FQDN = "DC=" + $ADDomain.Name -Replace("\.",",DC=")
 
    $Results = New-Object Psobject
    $Results | Add-Member Noteproperty Domain $ADDomainName
    $Results | Add-Member Noteproperty FQDN $FQDN
    $Results | Add-Member Noteproperty Server $ADServer
    $Results | Add-Member Noteproperty Netbios $Netbios
    Write-Output $Results
}

Usage is pretty simple:

Get-ADInfo

Thats all! :)

Getting Netbios name:

(Get-ADInfo).Netbios

Getting FQDN:

(Get-ADInfo).FQDN

Getting Active Directory Domain Name:

(Get-ADInfo).$ADDomainName

Getting Active Directory Primary Server Name:

(Get-ADInfo).$ADServer

You can use this in your all scripts. You no longer need any active directory information.
