Installing Ubiquiti UniFi Controller 5 on Raspberry Pi

Installing Ubiquiti UniFi Controller 5 on Raspberry Pi
UniFi

The next step is to install the UniFi Controller software.

Add the UniFi repository to the sources list, using the following commands:

echo 'deb http://www.ubnt.com/downloads/unifi/debian unifi5 ubiquiti' | sudo tee -a /etc/apt/sources.list.d/ubnt.list > /dev/null
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv C0A52C50
sudo apt-get update

Install UniFi, using the following package install command:

sudo apt-get install unifi -y

*The installation takes a couple of minutes to complete, but is fully automated and includes all the prerequisite components such as MongoDB and OpenJDK Java 7.

Disable the default MongoDB database instance, using the following commands:

echo 'ENABLE_MONGODB=no' | sudo tee -a /etc/mongodb.conf > /dev/null

Without making this small configuration change, you will have two separate instances of MongoDB running; an unused default database instance, and the UniFi database instance. This is obviously not desirable on a device with limited resources, such as the Raspberry Pi.

Update to the latest release of the Snappy Java Library, using the following commands:

cd /usr/lib/unifi/lib
sudo rm snappy-java-1.0.5.jar
sudo wget http://central.maven.org/maven2/org/xerial/snappy/snappy-java/1.1.3-M1/snappy-java-1.1.3-M1.jar
sudo ln -s snappy-java-1.1.3-M1.jar snappy-java-1.0.5.jar

*This fixes a number of issues particularly with the older models of Raspberry Pi, but also brings the library well up-to-date as the version Ubiquiti includes with the UniFi package is from 2013.

Once completed, reboot your Raspberry Pi using the following command:
sudo reboot

When the reboot is complete, use a web browser to view HTTPS port 8443 on your Raspberry Pi:

https://(hostname.local/ip):8443

Updating

Before updating the UniFi Controller software, it is highly recommended that you first backup the controller configuration.

To update the UniFi Controller software to the latest version, simply use the standard Debian package update and upgrade commands:

sudo apt-get update && sudo apt-get upgrade -y

The UniFi Controller software will be updated along with all other packages installed on your Raspberry Pi.

Alternatively, if you just want to update the UniFi Controller software only, run the initial package installation command again:

sudo apt-get install unifi -y

New-MailboxImportRequest -Mailbox “Administrator” -FilePath “\\Exchange\Backup_PSTs\administrator.pst”

  • EXPORT MAILBOX:

New-MailboxExportRequest -Mailbox administrator -FilePath “\\Exchange\Backup_PSTs\administrator.pst”

  • EXPORT ALLE MAILBOXE:

foreach ($i in (Get-Mailbox)) { New-MailboxExportRequest -Mailbox $i -FilePath “\\Exchange\Backup_PSTs\$($i.Alias).pst” }

  • EXPORT ALLE FRA OU:

foreach ($i in (Get-Mailbox -OrganizationalUnit “domain.dk”)) { New-MailboxExportRequest -Mailbox $i -FilePath “\\Exchange\Backup_PSTs\$($i.Alias).pst” }

  • SE STATUS PÅ EXPORT:

Get-MailboxExportRequest | Get-MailboxExportRequestStatistics

  • Full Accesss to All Mailboxes

Get-Mailbox -ResultSize unlimited -Filter {(RecipientTypeDetails -eq ‘UserMailbox’) -and (Alias -ne ‘Admin’)} | Add-MailboxPermission -User Administrator@domain.dk -AccessRights fullaccess -InheritanceType all

  • List Mailboxes by mailbox databases

Get-Mailbox | Sort database, name | Format-Table name, database

  • Move all mailboxes from one database to another database

1. Launch the Exchange Management Shell > Firstly lets get the names of my Databases, then I can simply copy and paste them into the move mailbox command.

Get-MailboxDatabase

Get-Mailbox -Database “Source Database Name” -ResultSize Unlimited | New-MoveRequest -TargetDatabase “Target Database Name

2. The Mailbox moves should then be queued, depending on how many there are, this can take some time to complete.

3. To check on progress issue the following command;

Get-MoveRequestStatistics -MoveRequestQueue “Target Database Name
 

4. When complete you should remove the movement requests like so;

Get-MoveRequest | where {$_.status -eq “Completed”} | Remove-MoveRequest
 

5. That’s all the ‘user’ mailboxes, but your source database server may have system mailboxes in it. These will be either Arbitration mailboxes, or Archive Mailboxes (or both). I don’t have any archive mailboxes, but I do have Arbitration mailboxes. To find out for your databases, use the following commands;

Get-Mailbox -Database “Source Database Name” -Arbitration

Get-Mailbox -Database “Source Database Name” -Archive

6. To move Arbitration and Archive mailboxes, use the following commands;

Get-Mailbox -Database “Source Database Name” -Arbitration | New-MoveRequest -TargetDatabase “Target Database Name

Get-Mailbox -Database “Source Database Name” -Archive | New-MoveRequest -TargetDatabase “Target Database Name

7. You can monitor progress with the same command you used in step 3, and remove the move requests with the same command you used in step 

 

Here is some useful Powershell Commands for reports:

List All Email Adresses in a .txt file

Get-recipient -resultsize unlimited | select Name -expand emailaddresses > c:\emailadresses.txt

List All Mailbox Sizes in a .html file

Get-MailboxStatistics -server “?” | Sort-Object TotalItemSize -Descending | convertto-html DisplayName,TotalItemSize, ItemCount, LastLogonTime, @{label=”TotalItemSize(MB)”;expression={$_.TotalItemSize.Value.ToMB()}} | set-content c:\mailboxsizes.html

List Mailboxes by mailbox databases

Get-Mailbox | Sort database, name | Format-Table name, database

Flash Drive with Multiple Versions of Windows

How to Create a Master Installation Flash Drive with Multiple Versions of Windows

wmi_top

You’ve got your collection of Windows ISOs and maybe you’ve burned installation DVDs or flash drives for them. But why not make yourself a master installation drive that you can use to install any version of Windows?

Setting up a bootable USB Drive that includes multiple ISOs is actually pretty easy, We’re going to do it using a clever little free tool named WinSetupFromUSB, so go ahead and download the latest version of that. You can even include some non-windows ISOs on the disk, like Linux distributions and antivirus rescue disks. For a complete list of what you can include on your USB drive, check out their supported sources page. There is one important note from that page worth calling out. The tool works with single Windows ISOs from Microsoft. If you have a dual ISO that includes both the 32-bit and 64-bit versions of Windows, you won’t be able to use it. But you can always download single ISOs (one for 32-bit and one for 64-bit) and stick them both on the USB if you need to.

Next, make sure you have blank USB drive big enough to hold all the ISOs you want to install, along with a little extra space. A 16 GB drive should give you enough space for two or three versions of Windows. If you have a 32 GB drive, you should be able to fit all the versions of Windows you could want. If you want to include other ISOs as well, you might need a bigger drive.

WinSetupFromUSB is a portable tool, so there’s no installation. Once you have it downloaded, double-click the archive to extract the files a new folder. If you’re running a 64-bit version of Windows, run the executable with “x64” in the name. If you’re running a 32-bit version of Windows, run the file without the “x64” in the name.

wmi_1

If you already had your USB drive inserted when you launched the tool, it should be listed in the box at the top of the window. If you didn’t have it inserted already, go ahead and plug it in now and then click Refresh.

wmi_2

Next, click the “Advanced Options” check box.

wmi_3

Instead of working like a regular check box, clicking it opens an “Advanced Options” dialog box. In the Advanced Options dialog, select the “Custom menu names for Vista/7/8/10/Server Source” check box. This setting allows you to provide your own names for the folders in which the Windows ISOs are stored and the boot menu names you see when you start a computer using the USB drive. You can close the “Advanced options” dialog when you’re done.

wmi_4

Now comes the somewhat tricky part. You’ll be adding Windows versions one at a time. The first time you add something to the USB drive (and only the first time), you’ll want to make sure that the “Auto format it with FBinst” check box is selected. This lets WinSetupFromUSB format the drive appropriately for booting. If you know you’ll be booting a computer in UEFI mode (or if you’re unsure), then select the “FAT32” option. Otherwise, you can use the “NTFS” option.

wmi_5

Next, select your first Windows ISO. Select the check box next to the “Windows Vista / 7 / 8 / 10 /Server 2008/2012 based ISO” section and then click the browse button (“…”) to its right. Locate and open the ISO you want to add.

wmi_6

If it’s a large ISO and you’re using the FAT32 file system, you may get a notification that the file is too large and will be split in two. That’s fine, so go ahead and click OK.

wmi_7

Double-check that you have the correct USB drive selected at the top of the window and that the right ISO is shown in the box. Then, click “GO.”

wmi_8

If you’re using a large USB drive, you may get a warning asking if you’re sure that’s the drive you want to use. Go ahead and click “Yes.”

wmi_9

If the auto format option is enabled (and it should be for the first ISO you add to a disk), you’ll also get a warning letting you know that the drive will be formatted and anything on it will be erased. Click “Yes” to continue.

wmi_10

WinSetupFromUSB will now format the drive and then pop up a window where you can enter a custom folder name for the ISO that’s between 1 and 7 characters. If you don’t type anything for 30 seconds, the default will be used automatically.

wmi_11

A similar window will now open that lets you type a custom name that should appear in the boot menu. This time, the name can be between 5 and 35 characters, so you have a bit more room to be specific. And again, you have 30 seconds to type a new name before the default is used automatically.

wmi_12

At this point, WinSetupFromUSB will begin creating folders, adding the ISO to your USB drive, and adding the options to the boot menu. This can take several minutes and you can gauge the progress in the window’s status bar.

wmi_13

When WinSetupFromUSB is done, you’ll get a simple “Job done” confirmation window. Click “OK.”

wmi_14

WinSetupFromUSB now returns you to the main window. You can exit the program or you can continue adding additional ISOs to your boot disk. You’ll add additional ISOs using the same process, but there are a couple of things to keep in mind as you do it:

  • When you add additional ISOs to an existing boot disk, make sure the “Auto format it with FBinst” check box is not selected. It won’t be by default when you return to the window (or when you start the program again), but it doesn’t hurt to make sure. You only want to format the disk with the very first ISO you add.
  • You’ll need to click “Advanced Options” and enable the “Custom menu names for Vista/7/8/10/Server Source” check box each time you add a new ISO. Make sure you don’t forget this step before clicking Go or you won’t be able to add a custom name for the ISO to your menu.

But that’s it. Otherwise, just follow the same steps each time you want to add a new ISO to the boot disk. You don’t have to add them all in one session either. You can come back any time and add something new. When you’re done, you can boot up a computer using your USB drive (which you may be able to do even if your BIOS won’t let you) and be rewarded with a nice boot menu like this:

wmi_15

While it doesn’t sport the most intuitive interface, WinSetupFromUSB is lightweight and works well. And once you get the hang of adding ISOs to the package, it’s a breeze to set yourself up with a powerful boot disk that will let you install whatever version of Windows you want, as well as a number of other bootable tools.

DPI Settings on RDP Sessions

The DPI settings are the settings that enables you to change the size of all fonts and other UI elements on the computer. But unfortunately, by default, you don’t get to change it through a remote desktop session that runs on a Windows 7 or Windows Server 2008 R2 computer. They are grayed out, like below.

DPI-setting-on-a-RDP-session

You may want to ask why we need it to change the font size on a remote session. Believe me, when you use a laptop or tablet that runs on a very high resolution like Surface Pro 3, you will need a larger font on a remote desktop session. Otherwise, the font will be too small to read on the screen.

To fix it, you will need a special hotfix from Microsoft.

Outlook – Error “The name of the security certificate is invalid or does not match the name of the site.”

Problem
Seen in Outlook when connecting to a mailbox on an Exchange Server, its caused by using a self signed certificate OR a purchased certificate, where the internal and external names are different.

 

Solution
1. On the Exchange Server > Start > All Programs > Microsoft Exchange Server {version} > Exchange Management Console. Issue the following four commands;
Exchange 2010 and SBS 2011 (change the values in red)

Set-ClientAccessServer -Identity EXCHANGE-MAIL -AutodiscoverServiceInternalUri https://mail.publicdomain.co.uk/autodiscover/autodiscover.xml

Set-WebServicesVirtualDirectory -Identity “EXCHANGE-MAIL\EWS (Default Web Site)” –InternalUrl https://mail.publicdomain.co.uk/EWS/Exchange.asmx

Set-OABVirtualDirectory -Identity “EXCHANGE-MAIL\OAB (Default Web Site)” -InternalURL https://mail.publicdomain.co.uk/OAB

Set-ActiveSyncVirtualDirectory -Identity “EXCHANGE-MAIL\Microsoft-Server-ActiveSync (Default Web Site)” -InternalURL https://mail.publicdomain.co.uk/Microsoft-Server-Activesync

Outlook Anywhere Note

If you intend to use Outlook Anywhere, you may also want to execute the following command. Particularly if you use SBS, which has a habit of setting remote.publicdomain.com as the default outside name.

Set-WebServicesVirtualDirectory –Identity ‘EXCHANGE-MAIL\EWS (Default Web Site)’ –ExternalUrl https://mail.publicdomain.co.uk/ews/exchange.asmx

Exchange 2007 (change the values in red)

Set-ClientAccessServer -Identity EXCHANGE-MAIL -AutodiscoverServiceInternalUri https://mail.publicdomain.co.uk/autodiscover/autodiscover.xml

Set-WebServicesVirtualDirectory -Identity “EXCHANGE-MAIL\EWS (Default Web Site)” -InternalUrl https://mail.publicdomain.co.uk/ews/exchange.asmx

Set-OABVirtualDirectory -Identity “EXCHANGE-MAIL\oab (Default Web Site)” -InternalUrl https://mail.publicdomain.co.uk/oab

Set-UMVirtualDirectory -Identity “EXCHANGE-MAIL\unifiedmessaging (Default Web Site)” -InternalUrl https://mail.publicdomain.co.uk/unifiedmessaging/service.asmx
For Small Business Server 2008
For SBS 2008 the commands are Different! (the following commands are for Exchange 2007 on SBS 2008 ONLY;

Set-ClientAccessServer -Identity EXCHANGE-MAIL -AutodiscoverServiceInternalUri https://mail.publicdomain.co.uk/autodiscover/autodiscover.xml

Set-WebServicesVirtualDirectory -Identity “EXCHANGE-MAIL\EWS (SBS Web Applications)” -InternalUrl https://mail.publicdomain.co.uk/ews/exchange.asmx

Set-OABVirtualDirectory -Identity “EXCHANGE-MAIL\oab (SBS Web Applications)” -InternalUrl https://mail.publicdomain.co.uk/oab

et-UMVirtualDirectory -Identity “EXCHANGE-MAIL\unifiedmessaging (SBS Web Applications)” -InternalUrl https://mail.publicdomain.co.uk/unifiedmessaging/service.asmx
Note: where EXCHANGE-MAIL is internal and mail.publicdomain.co.uk is external name

2. Then open the IIS Manager Expand Application Pools > MSExchangeAutodiscoverAppPool > Right Click > Recycle.
Note: You may have to enter the FQDN of the server rather than its Netbios name!!
