# Usual directory for downloading software in ProtoGENI hosts is `/local`
cd /local
#Get the hostname to see if we are at the server or the client
hn=`echo $HOSTNAME | cut -d'.' -f 1`

##### Check if file is there #####
if [ ! -f "./installed.txt" ]
then
       #### Create the file ####
        sh -i -c `sudo touch "./installed.txt"`

       #### Run  one-time commands ####

       #Install necessary packages
        sudo apt-get update
        sudo apt-get -y install apache2 iperf & EPID=$!
        wait $EPID 

       # Install custom software
       ## Customize apache installation


       ## Reboot the host if needed
fi
##### Run Boot-time commands
# Start services
# If this is the server then start the iperf and configure and start the http server
if [ $hn == "server" ]
then

   # Enable web server stats
   sudo /usr/sbin/a2enmod status
   sudo rm /etc/apache2/mods-enabled/status.conf
 
   echo "<Location /server-status>" | sudo tee -a /etc/apache2/sites-available/default > /dev/null
   echo "   SetHandler server-status" |sudo tee -a /etc/apache2/sites-available/default > /dev/null
   echo "   Allow from all" | sudo tee -a /etc/apache2/sites-available/default > /dev/null
   echo "</Location>" | sudo tee -a /etc/apache2/sites-available/default > /dev/null
   echo "ExtendedStatus On" | sudo tee -a /etc/apache2/conf.d/extendedstatus > /dev/null

   # Copy the website under /var/www/
   sudo cp -R ./website/* /var/www/
   sudo rm -rf /var/www/html
   sudo ln -s /var/www/ /var/www/html

   # Start the webserver
   sudo /usr/sbin/apache2ctl restart
   sudo service apache2 restart

   # Start the iperf server
   sudo mkdir -p /var/www/iperflogs
   iperf_server_log="/var/www/iperflogs/iperf-server.log"
   sudo bash -c "iperf -s -i 10 &> $iperf_server_log"
else
  # If this is the client start the script for transfers
  # Wait 60 seconds just to give some time to the server to come up
  sleep 60
  ./scripts/client-wget.sh&
  ./scripts/client-iperf.sh&
fi
# Start my service -- assume it was installed at /usr/local/bin

2. Establish the Environment

  1. Execute these commands:
        $ cd mydir
        $ ssh my.host.com
    

Expected Output

   This is the output that I should see

3. Obtain Resources

  1. Use diagrams and screenshots to show topologies and user interfaces. Label your figures for easy reference.
    Login information for a VM

    Figure (1)
  1. Videos are a great tool to illustrate multi-step visual processes. Make sure to also include the textual steps, however, in case they are not able to play the video.
Login to Flack Video
  1. Go to http://www.protogeni.net/flack and press the Log in button
  2. From the select authority drop down menu, select the site authority for your GENI account, most probably pgeni.gpolab.bbn.com and press the Download button
  3. Answer yes in the pop-up window
  4. Login to the new window using your GENI account
  5. Reload the Flack tab and repeat steps 1 and 2
  6. After your private key and certificate are loaded, type your GENI passphrase in the box
  7. Select the sites you want. For this tutorial we only need the utahemulab.cm site.
