# Mount root partition:
sudo mount /dev/sdXY /mnt # /dev/sdXY is your root partition, e.g. /dev/sda1

# If you have a separate boot partition you'll need to mount it also:
sudo mount /dev/sdYY /mnt/boot

# Mount your virtual filesystems:
for i in /dev /dev/pts /proc /sys /run; do sudo mount -B $i /mnt$i; done

# Chroot
sudo chroot /mnt

sudo grub-mkconfig > /boot/grub/grub.cfg
sudo grub-install /dev/sda

root@backup_server /mnt/old_root/var/lib/dpkg/info # ls -la *.list | awk {'print $9'}| sed 's/.list//' >> /root/installed_app

Yes!

From askubuntu.com

sudo apt-get install mdadm
sudo mdadm --assemble --scan

After running those two commands in the terminal, you should be able to mount the drive as usual (either by clicking in the file manager, or by using the mount command)

From askubuntu.com

You can use:
sudo shred -v /dev/sdb

From Ubuntu Gnome Wiki

sudo apt-get install ubuntu-gnome-deskop
dpkg will prompt asking which display manager you want to use, select 'gdm'

When using xargs, you will eventually run into a file that contains spaces or quotes in its name.

First Step:
Convert the cert into a Java Keystore:
openssl pkcs12 -export -name mycert.local -in /etc/ssl/certs/mycert.local.cert -inkey /etc/ssl/private/mycert.local.key -out mycert.local.keystore.p12

Second Step:
Import the new keystore (Using the primary java keystore of an Oracle Java install on Linux here:
keytool -importkeystore -srckeystore mycert.local.keystore.p12 -destkeystore /usr/lib/jvm/default-java/jre/lib/security/cacerts -srcstoretype pkcs12

For an additional 7200rpm and 5400rpm drive in a system with the os installed on an SSD

# Create partition for entire drive in Gparted

# setup crypt volume
sudo cryptsetup -v luksFormat /dev/sdc1
sudo cryptsetup -v luksFormat /dev/sda1

# open the crypt volume manually
sudo cryptsetup open --type luks /dev/sdc1 sdc1_crypt
sudo cryptsetup open --type luks /dev/sda1 sda1_crypt

# Create the physical drive
sudo pvcreate /dev/mapper/sda1_crypt
sudo pvcreate /dev/mapper/sdc1_crypt

# Now it shows up below
# View uuids and devices
sudo blkid

# View lvm physical devices

# View lvm logical devices

# Create Logical Group
sudo vgcreate allegro /dev/mapper/sdc1_crypt
sudo vgcreate moderato /dev/mapper/sda1_crypt

# Create Logical Volume
sudo lvcreate -L 600G allegro -n allegroVol
sudo lvcreate -L 900G moderato -n moderatoVol

sudo mkfs.ext4 /dev/mapper/allegro-allegroVol
sudo mkfs.ext4 /dev/mapper/moderato-moderatoVol

# add to /etc/crypttab

I like VirtualBox and think its a great tool, however, this was necessary for me because of work.

Installation

Installing Vmware Workstation 10 on Ubuntu 12 (Works for Ubuntu 13 as well)

Conversion

You can convert VirtualBox images to Vmware ones with the following process:

1. Export the machine from VirtualBox as a standard ova
2. Import to Vmware, which will fail right away, until you hit "Retry" whereupon it will work just fine
3. Look at the settings and remove anything that looks unnecessary (Floppy controller, sound card if it's a server)
4. Start the vm, you may have to resolve a hardware issue (ide mounted in wrong location or some such)
5. Install the vmware tools
6. Optionally, uninstall virtualbox-tools

Vmware Fusion network settings

If you want to match an apple wielding colleagues vmware fusion network settings, you can find your colleagues network setting on their mac at: /Library/Preferences/VMware Fusion

Windows Guest Display Resolution

If you are running a Windows Guest, you can set any resolution of the Desktop by using VMwareResolutionSet.exe
I have two scripts that I can run on a windows Host based upon if I want a full size screen or a half-sized (width):
full:
"C:\Program Files\VMware\VMware Tools\VMwareResolutionSet.exe" 0 1 , 0 0 1900 970
half:
"C:\Program Files\VMware\VMware Tools\VMwareResolutionSet.exe" 0 1 , 0 0 940 970

Ubuntu Key mapping restoration after exiting a vm

If you are having difficulties with the Ctrl/OS/Alt keys after coming out of a vm, you might be experiencing this issue. You can restore some functionality by entering the following command in the terminal:
setxkbmap
