Hi, I'm just getting started with Raspberry and I see that they have a new software version released on 12/24/14. I don't know what version that I have now (I got it in November). My primary goal is to pass on weather data from my Acurite Weather system to Weather underground. I also just purchased a 5" Eleduino display unit to use instead of my TV connection and it is supplied with it's own customized version of Raspbian to make installation easier....They also have the necessary scripts, so if you didn't want to use their version, you could manually change with the scripting.
My Current Questions:
1) Since I don't know either version number that I have, what happens if I use the the Eleduino .RAR file and apply the update. Will I lose the files that I currently have written?
2) Assuming the customized (for display) works fine, what happens when I go to Raspberry.org and install the latest version.....Will I lose all the changes that Eleduino put in to make their display work?
3) Programming question - I have started copying script (for my weather app) from http://nincehelser.com/ipwx/ and I've reached a point that has me stopped.
In this section: "To keep things orderly, I suggest creating a new user “ipwx” with its own home directory with the following commands:
sudo adduser ipwx (done)
Add an entry in /etc/sudoers file similar to the user “pi” to allow ipwx administrative privileges. .
ipwx ALL=(ALL) NOPASSWD: ALL (done)
Now log out and then log back in as the user “ipwx”
Create a new file “listener” with the following line. It may be hard to tell the ells from the pipes and zeros from the ohs, so you might want to cut-and-paste.
sudo tcpdump -A -n -p -l -i eth0 -s0 -w - tcp dst port 80 | stdbuf -oL strings -n8 | stdbuf -oL egrep "mt=5N1|mt=pressure"
(did that, but he didn't say where to put this file - so I put in the ipwx folder)
Make sure “listener” executable...
sudo chmod +x listener (done)
Now you can test to see if your Acurite Internet Bridge is working properly. (it is hooked up, isn’t it?)
./listener
Now, when I try it I don't know where to issue the ./listener command...Is it at the root, at the home directory level, or at the ipwx folder level?
I also have gotten the message that I don['t have permission to access that file, yet, as per above, I applied the Nopasswd command as stated above.
It doesn't matter if I am logged in as "pi" user or "ipwx" user.....I assume that I must be logged in as "ipwx" user since that's where the "Listener" folder is located.
Someone please help
Thank you
Bob
