• Any other odds or ends?
• @ the control shed

How I think things will work

1. Gain access to the control shed
2. Look to see if the lights are active on the dreamplug (ie is it getting power)
3. If yes...
   1. Try using //PUTTY// to ssh to the dreamplug.
   2. First, disconnect the port 1 ethernet cable, which connects to the webcam
   3. connect another ethernet cable between port 1 on the dreamplug and the laptop
   4. when you connect your laptop to the dreamplug if it is working fine it should dynamically supply an IP address using DHCP
   5. IP address for the server will be 192.168.1.1; port initially is 22; user will be bob
   6. If you're able to log in... awesome!
      1. let's try a few commands then. Here are some commands:
      2. su root --> typing this will allow you to become the root user, which is used for configuration and advanced management.
      3. ifconfig --> this will output to the screen the current ip address of the dreamplug. there is a lot of information that will be spit out. eth0 = connection to the greater internet & eth1 = connection to the webcam.
      4. nano --> this is a simple text editor. To use it, from the command line type nano followed by the file name. for example nano textfile.txt
         1. important nano commands: <CONTROL><X> = exit & save
         2. <CONTROL><O> = save
         3. <ESCAPE><\> = fast forward to the last line of the program
      5. cat $filename = output to the terminal screen the contents of a file (like a text file)
      6. tail $filename = output to the terminal screen the last 10 lines of a text file
      7. cd = change directory. so, like cd .. or cd /etc/ or cd /home/bob/bin. invoking that command will take you different places. Also, to denote directories in linux you'll use the forward slash as shown there so /home/bob/bin is three directories in from the root directory.
      8. exit --> this is how you log out
      9. shutdown now -r --> slightly more complex, typing this will restart the dreamplug.
      10. nano /etc/network/interfaces --> I
