1 Using OpenStack

Step 1 - Create and Instance


  • Use the form to setup your instance settings. Give your instance a sensible name of your own though.


  • Click on the Post-Creation tab


  • Copy and paste the following code into Customization-Script box.
password: mysecret
chpasswd: { expire: False }
ssh_pwauth: True
  • Then click the Launch button

Step 2 - Setup using the Cloud-Console

  • After a minute or two your instance will be ready to use


  • Click on the blue hyperlink to view your instance.


  • From here you can access your instance via the terminal.


  • If you can't seem to type in the terminal, click on the grey area of the screen.
  • Your username will be ubuntu and your password will be mysecret

Step 2 - Settin up your account

  • You probably don't want the username ubuntu so let's add a new user account.
  • Replace newUser with the username you want to use
sudo adduser newUser
  • You'll be prompted to give the user a UNIX password and enter some information.
  • Next you'll want the new user to have sudo privaledges
sudo adduser newUser sudo
  • We can now switch to that user
  • Let's delete the old user now, to lock down our instance a little.
sudo userdel -r ubuntu

Step 2 - Setting up your software

  • First update and upgrade your instance
sudo apt-get update
sudo apt-get upgrade
  • Now we'll need a few packages. Emacs for writing text, cifs-utils for mounting windows drives and git for version control.
sudo apt-get install emacs24 cifs-utils git
  • This one might take some time.

Step 2 - Mounting Windows folders

  • You'll want to mount your Windows Home Folder securely.
  • First we'll need to create a mount point
sudo mkdir /media/windows
  • First let's create a file to save your username and password.
emacs ~/.smbcredentials
  • This file will need two lines where myUserName and myPassword are your passwords to the Windows Network
  • Save the file (C-x C-s) and quit Emacs (C-x X-c)
  • Next we'll need to change the permissions on the file we've just created, so only you can see it.
chmod 600 ~/.smbcredentials
  • And next we'll need to edit a file called /etc/fstab so it knows where the Windows Share is
  • Open it in emacs
sudo emacs /etc/fstab
  • Add this line to the bottom of the file
  • Note the difference between your Linux and Windows username. Also note that you need a $ at the end of your Windows username.
//brgras005/WindowsUserName$ /media/windows cifs credentials=/home/LinuxUserName/.smbcredentials,iocharset=utf8,sec=ntlm 0 0
  • Let's make a symlink to the /media/window folder
ln -s /media/windows ~/windows
  • And now mount the drive
sudo mount -a
