Hint: With firefox use plugin ”FoxyProxy”. it makes working with proxies a lot easier.
In foxy proxy use these two patterns with this proxy: ”*130.233.42.*” and ”*quebec.niksula.hut.fi*"

3. Open the dashboard at http://quebec.niksula.hut.fi and login using your username and password.

Initially the username and password is same as with echo. You can change it using the dashboard

Set up command line access

1. Copy openstack credentials to echo.niksula.hut.fi

You can download the credentials file from Dashboard: Project -> Access & Security -> API Access -> Download OpenStack RC File
Save the file to echo. Filename does not matter. Example: openstackrc.sh
For transferring the file you can use command scp, on windows application WinSCP or just create new text file on echo (using text editor such as vim, nano or emacs) and copy-pasting the contents of downloaded settings file.

2. Source credentials in your terminal: "source openstackrc.sh"

You need to do this every time you open new terminal window on echo.

3. Try running some openstack commands

neutron net-list
nova list
If you did not get any errors, you are good to go!

4. Create ssh key pair for accessing instances

Dashboard: Project -> Access & Security -> Key Pairs -> Create Key Pair
Give name to the new key pair and save the private key file to echo as ~/.ssh/id_rsa
Add the private key to ssh-agent

ssh-add ~/.ssh/id_rsa

Accessing virtual machine instances in OpenStack

Note: You can do this only after you have created VM instance (Assignment A1 & B1)

Due to Aalto IT policy the virtual machines are secured with very restrictive firewall. This means that VM’s are not accessible from public Internet directly. Every connection must go through echo.niksula.hut.fi. However, outgoing connections are allowed, so your virtual machines can access internet normally (downloading software packages work as expected).

1. Connect to echo.cs.hut.fi (if you already haven’t done that) ”ssh username@echo.niksula.hut.fi"

You can open multiple simultaneous connections if you need. Just don’t try to create multiple socks proxies (the ”-D 9999” thing)

2. Make sure you have ssh-agent running somewhere, either on your own computer or on echo

command ”ssh-add -L” should work

3. Connect to your lab1 machine using the floating ip you assigned to your machine

”ssh ubuntu@lab1_floating_ip"

4. Enable agent forwarding on lab1

echo ”echo -e 'Host *\n ForwardAgent yes' >> .ssh/config"

5. Connect to lab2 & lab3 from lab1

”ssh ubuntu@lab2_ip"

Read the documentation!

OpenStack usage is well documented, see http://docs.openstack.org/user-guide/content/
Especially sections "1. OpenStack dashboard" and "2. OpenStack command-line clients" are useful

Useful OpenStack commands

”nova”: Manage OpenStack virtual machines (instances)
”neutron”: manage OpenStack virtual networks
”glance”: manage OpenStack virtual machine images

Hints

Learn to use tmux. It will make your life easier
- Launch multiple terminals on echo, keep each connected to different virtual machines
- Connections can be kept open even if you log out yourself
- Great tutorial
Customize shell login file (default ~/.bash_login)
- source credentials automatically
Add ssh public key to echo and your local machine as well
