For those looking for the default PIN for the bluetooth connection of a HP OfficeJet H470, it's 0 0 0 0.

Although it can be found in the manual somewhere, it's easily overlooked.

Sometimes, you need to temporarily start a service (such as SSH) to perform some maintenance task. PowerCLI can help you with this:

To start the SSH server on each host of a vCenter:

Get-VMHost | Get-VMHostService | ? {$_.Key -eq "TSM-SSH"} | Start-VMHostService

To stop the SSH server:

Get-VMHost | Get-VMHostService | ? {$_.Key -eq "TSM-SSH"} | Stop-VMHostService -Confirm:$false

As always, you can make adjustments to the oneliner to select another service to start/stop, or further limit the selection of hosts to a cluster or a group of hosts (e.g. filtered by name).

If you're making changes to the datastore, setting up a new cluster and have a lot of hosts, and wish to set up system logging, you can do so very quickly using PowerCLI.

First, add all the hosts to the vCenter like you normally would. Then, connect to the vCenter server and run this cmdlet:

Get-VMHost | % { $vm = $_ $vm | Get-AdvancedSetting "Syslog.global.logDirUnique" | Set-AdvancedSetting -Value "True" -Confirm:$false $vm | Get-AdvancedSetting "Syslog.global.logDir" | Set-AdvancedSetting -Value "[DataStore01] ESXiLogs" -Confirm:$false}

The cmdlet above will set the system log location to a folder on DataStore01 and enables unique log di  ...

When performing large storage migrations, it may be useful to get a list of VMs and the datastore and/or folder they are located in. PowerCLI can provide this very quickly:

Get-VM | Select Name,@{N="Datastore";E={[string]::Join(',',(Get-Datastore -Id $_.DatastoreIdList | Select -ExpandProperty Name))}},@{N="Folder";E={$_.Folder.Name}}

You can further pipe this to other cmdlets (such as Where-Object to filter even more), or export it to a CSV.

You can also go into more detail and determine the location of each virtual disk (VMDK) of each VM:

Get-VM | Get-View | % { $name = $_.Name $_.Layout.Disk | % { New-Object PSObject -Property @{ Nam  ...

For all you Belgians (Flemish) out there, a list of live-streams (MP3) for people who don't want to use the online player of VRT, or simply can't use the player (e.g. linux users?)

Simply load these up in your favourite player supporting MP3 streaming through HTTP (such as VLC Player).

Where are the URLs? (UPDATE Aug-2017)

Readers that have read this page before will notice all streaming URLs are gone. VRT has switched to another streaming provider, causing all streaming URLs to change. The new list can be found here:

For those that do not wish to use OneDrive and want it removed from the folder tree in Explorer, can do so by a simple registry change:

Open regedit and locate the key: HKEY_CLASSES_ROOT\CLSID\{018D5C66-4533-4307-9B53-224DE2ED1FE6}

Change the value of System.IsPinnedToNameSpaceTree to 0

When using 64-bit, repeat the process for the key: HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{018D5C66-4533-4307-9B53-224DE2ED1FE6}

Note that starting from Windows 10 Creator, you can also remove OneDrive by uninstalling it:

  • Right-click OneDrive in the start menu and click "Uninstall"
  • Go to Control Panel → Add/Remove Programs and uninstall it from the list.

As found on Voip-info.org, a list of bandwidth consumption per codec.

It's worth mentioning that the table also indicates the total consumption including IP overhead. When making assumptions about bandwidth requirements, it is useful to take this overhead into account.

G.729 8 Kbps 31.2 Kbps
G.723.1 6.4 Kbps 21.9 Kbps

You can easily verify whether an ADFS implementation is working by using a browser and trying to log on:

https://adfs.yourdomain.com/adfs/ls/IdpInitiatedSignon.aspx

Replace adfs.yourdomain.com accordingly.

Note that in 2016, this no longer works unless you re-enable this feature through Powershell:

Set-AdfsProperties -EnableIdpInitiatedSignonPage $true

To properly shut down the NetApp (through the CLI):

First, close down all I/O to the NetApp by dismounting volumes, turning off servers, etc.

Log in on the NetApp through the CLI, using either a console cable or via SSH. Note that if you use SSH, you will not be able to see the complete shutdown sequence.

On the first controller, turn off cluster failover: cf disable



Shut down the controller: halt



Log on to the other controller (using SSH or swap the console cable), then shut down that controller too: halt



Wait until the shutdown sequence has completed before removing power from the controller chassis, then turn off the enclosures. You can use a console cable to verify whether th  ...

To create an UEFI-bootable USB installer for ESXi 6.5 (or newer) on a Mac, follow the steps below.

First, you'll need an USB flash drive. Any recent drive will be large enough (you'll need at least 512MB). Also, download the latest ESXi installer ISO from My VMWare. You probably need a My VMWare account.

With the prereqs in place:

Insert the USB flash drive in the Mac and start up Disk Utility.

Erase the USB flash drive and choose to format it:Partition map = MBR

Filesystem = FAT32

Give it a descriptive name of your choosing.

After erasing the drive, we still have to mark the one partition on it as "active". Disk Utility does not support this and needs to be done using Termi  ...

The RLM module may become unresponsive and you may see the following messages in the Syslog:

Syslog
The software driver for the Remote LAN Module (RLM) detected a problem: Unable to update SP network information at this time.

You can resolve the issue by rebooting the RLM from the CLI.

Log on using the CLI (SSH or console), then reboot the RLM.

CLI: rlm reboot

Wait for a while and verify the RLM is back online:

CLI: rlm status

The output of the command should report: Status: Online

I got this through the contact form. It's a jargon-free guide to computer and internet security. It provides a detailed explanation on how to properly secure your computer and internet experience, and best of all, it uses simple and understandable language, lowering the bar for everyone to secure themselves against malware, ransomware and other malicious attacks.

Although unsupported, it is possible to install Microsoft Security Essentials on a Windows Server 2012.

To do this, set the compatibility of the downloaded file to Windows 7, then start that file with the parameter /disableoslimit.

The installation goes without a problem, and as far as I can tell, there are no compatibility issues.

If for any reason you need to determine whether a specific instance of VMWare View Connection Server is installed as a standalone server or a replica server, you can do so by looking into the registry.

In HKEY_LOCAL_MACHINE\Software\VMware, Inc.\VMware VDM, the value ServerInstanceType will indicate which type the CS is:

1 = standalone/first CS
2 = replica CS

Note that this doesn't really matter, as the only difference between them is whether they set up a new ADAM instance or connect to an existing one. After the installation of VCS, they are identical.

Quest Rapid Recovery provides the ability to replicate restore points to off-site location. More than often, connectivity to these locations has limited bandwidth and is sometimes even unstable. Unfortunately, Rapid Recovery doesn't do well with unstable connectivity: more than often, replication jobs abort because of high latency. Luckily, you can tweak the timeout parameters through the registry:

HKEY_LOCAL_MACHINE\SOFTWARE\AppRecovery\Core\CoreSettings\ClientTimeoutSettings Increase the values of ReadWriteTimeout and ConnectionTimeout to 1 hour.

HKEY_LOCAL_MACHINE\SOFTWARE\AppRecovery\Core\Replication\ReplicationService Increase the values of VolumeImageSessionTimeout and RemoteReplicat  ...

You can very easily properly uninstall the Palo Alto GlobalProtect client on Mac OSX by running the included uninstallation script:

Open a Terminal and then run it by typing:

sudo /Applications/GlobalProtect.app/Contents/Resources/uninstall_gp.sh

Provide your password when asked and the script will uninstall GlobalProtect.

On October 31 2017, RPC over HTTP will be deprecated in Office 365, as stated here. This means that older Outlook versions (those that use RPC over HTTP) will no longer be able to connect to Office 365. The reason for this is that RPC over HTTP will be replaced in favor of the much newer MAPI over HTTP.

This switchover has an impact on all (older) Outlook versions that do not have the required update (incorporating MAPI over HTTP) functionality installed. Only Outlook versions that get this update will be able to connect to Office 365, resulting in the following changes:

Outlook 2007: no longer supported (there is no update).

Outlook 2010: only supported with SP2 and KB 2878264 installed   ...

Firefox 52 introduced an insecure form warning: whenever a password is requested on a web form through a non-SSL website (i.e. no "https"), Firefox displays a warning popup below the focused field:

While the gesture is appreciated (user awareness and all), it can become annoying. There is a way to turn the warning off through the advanced configuration of Firefox:

Start up Firefox and enter the following URL in the address bar: about:config

You'll get a This might void your warranty! page. Click the I accept the risk! button to continue.

You'll get a list of everything there is to configure in Firefox. In the search bar, paste the following value to quickly locate the correct p  ...

Sometimes it may become necessary to make changes to a DHCP scope on your Windows DHCP Server. Unfortunately, for existing scopes, not all scope options are editable, and it can become quite a hassle to recreate the scope, especially when there are a lot of reservations. Luckily, there's a workaround which allows you to edit the scope options, which is by using netsh.

It is not possible for netsh to directly edit scope options, but you can create a dump of the complete scope configuration (including all reservations), edit the resulting file, and import it back into the DHCP server. For this to work, you'll need admin (elevated) privileges on the DHCP server.

One of the most common Exchange admin tasks is setting mailbox delegations. Personally, I usually do this through EAC but once you're familiar with the Powershell counterparts, it can be quicker to use that instead. I've created this post as a reference to do just that.

In the reference below, the user "Ellen Somebody" requires access to the mailbox of "John Doe".

Send on Behalf

Set-Mailbox john.doe -GrantSendOnBehalfTo ellen.somebody

Send As

Add-ADPermission john.doe -ExtendedRights Send-As -user ellen.somebody

Full Access

Add-MailboxPermission -Identity john.doe -User ellen.somebody -AccessRights FullAccess -InheritanceType All
