- 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
- Gain access to the control shed
- 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...
- 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.
- Try using PUTTY to ssh to the dreamplug.
- If you're able to log in... awesome!
- let's try a few commands then. Here are some commands:
- su root --> typing this will allow you to become the root user, which is used for configuration and advanced management.
- 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.
- 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
- important nano commands: <CONTROL><X> = exit & save
- <CONTROL><O> = save
- <ESCAPE><\> = fast forward to the last line of the program
- cat $filename = output to the terminal screen the contents of a file (like a text file)
- tail $filename = output to the terminal screen the last 10 lines of a text file
- 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.
- exit --> this is how you log out
- shutdown now -r --> slightly more complex, typing this will restart the dreamplug. need to do this after changing interface file
- nano /etc/network/interfaces --> couple of changes I anticipate making:
- iface eth0 inet static
- address 199.165.126.165
- If you're able to log in... awesome!
- if still not working, plug serial cable directly into toughbook
- save files into dropbox
- set up file retreival on loggernet
- show Umiaq personnel how to re-instal a dreamplug
- take pictures of current set up
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
