NGEE December 2014 Barrow

12/5/2014

• 9:45 Arrive at Airport
• 11:15am Fly to Barrow, on Alaska Flight 2817
• 6:10pm arrival
• 7:00pm Safety Training & Barrow Introduction (maybe?)

12/6/2014

• 9am Snowmachine training
• 9:30am Snowmachine to control shed
• 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 of 4 should be on)
   • If no, check power supply, replace if necessary
   • If yes...
3. disconnect the port 1 ethernet cable, which connects to the webcam (disable wireless on toughbook)
   • connect another ethernet cable between port 1 on the dreamplug and the laptop
   • when you connect your laptop to the dreamplug if it is working fine it should dynamically supply an IP address using DHCP
   • IP address for the server will be 192.168.1.1; port initially is 22 (if we use the replacement dreamplug the port will be 20593); user will be bob
   • Open command prompt (cmd) and ping 192.168.1.1
   • If doesn't work, ipconfig. If ethernet adapter local area connection, Media state reads 169.... then need to set up static IP address

   • control panel> Network and internet> Network Connections ->right click local area connection, IP Version 4, properties

   • IP: 192.168.1.5
   • subnet: 255.255.255.0
   • default gateway: 192.168.1.1

   • Ping again
   • Download data with loggernet

   • change dreamplug IP to 192.168.1.1
   • change the file names to reflect the date.
   • collect the data for A-D.

4. Try using PUTTY to ssh to the dreamplug.
   1. 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. need to do this after changing interface file
      10. nano /etc/network/interfaces --> couple of changes I anticipate making:
          1. iface eth0 inet static
          2. address 199.165.126.165
5. if still not working swap dreamplugs

Tools list:

• charged laptop
• laptop power cable
• putty installed on it
• serial cable
• Network cable (5 -10 feet long to stretch from dreamplug mounted on wall to the desk.
• Cell phone and charger
• Camera
