Cloning VMs in Virtual Box

There is no way to clone VMs from the GUI, You can clone inside the GUI now.  You can also clone the hard drives from the command line using:

VBoxManage clonevdi harddrive.vdi newharddrive.vdi

Then just create a new virtual machine in the GUI and use the new hard drive you cloned instead of creating a new one.



Exchange 2010 mailbox size list

Exchange 2010 doesn't have a GUI view where you can see the users listed with their mailbox size.  Luckily you can make your own list using the Exchange Management Shell.

Get-MailboxDatabase "<insert database name>" | Get-MailboxStatistics | Sort totalitemsize -desc | ft displayname, totalitemsize, itemcount

You can always add > somefile.txt and import it into excel if you need to make something pretty for management.

Wireshark on OS X

By default you get an error that no interfaces are available when you try to capture traffic. This is because you don't have access to the necessary parts of /dev/

To fix it:

sudo chown username /dev/bpf*
