Got a new toy over the holidays (a Raspberry Pi), so I thought I'd try installing Nodelink on it.  I have some other apps I need to run that require Raspbian 8.  Does the install script for Nodelink care which version of Raspbian I'm running?

Possibly not, but I would do my best to upgrade everything first. It may save you a lot of time/grief  later. It's always free.

If you mean upgrade to Raspbian 9 ... unfortunately that's not an option for me just yet, as the other apps I'd like to run won't work in that environment.

Not sure why but Nodelink installed itself over or into a used node slot. I got it all sorted out. Forced it into the node I wanted and then uploaded the profile.zip from the polyglot and everything is as it should be.

Any chance you have the log of it?  I'd like to see what NodeLink detected when it grabbed the slot list.

It's gone, but I remember there was an error reading the node slot list and something about it trying to install in a prohibited node /ns/0.

I will be setting up another one tomorrow or Sunday and if it happens again I will at least get a screen shot.

NodeLink installation on a Raspberry Pi is now a lot simpler.  On a running Pi you type:

sudo curl -sSL http://automationshack.com/Files/install.sh | bash

That's it.  It updates the Pi, installs mono, downloads NodeLink and sets up the startup script.

I have a RPi running Polyglot. It took quite some effort (and lots of help from Beninsteon and others) to get this far. How exactly do I add "   sudo curl -sSL http://automationshack.com/Files/install.sh | bash  " ?

Run the terminal screen on your RPi

pls remind me how to get to terminal screen ?

My Polyglot works with perfection. Is there any risk to impact Polyglot when adding Nodelink ?

I run both without any problems.

If you are running headless, you use Putty to sign on to the terminal screen. If you are running the GUI, the Terminal screen is in the menu.

If you log onto your RPi from another computer using the 'ssh' command, then you're already at the terminal once you're logged in.  If you have your RPi hooked up to a monitor, keyboard and mouse, and you're looking at a GUI when you log in, then you should be able to find the program named "terminal" somewhere on the box.  Just run it, and you'll be presented with a command prompt in a terminal window.  Alternatively, you might be able to switch to a command line terminal (full screen) by pressing and holding the ALT+CTRL+F2 (or substitute the F2 with F3 through F5) keys.  Switch back to the GUI with ALT+CTRL+F1.

I've been running Polyglot, Nodelike and Weatherflow node servers on my RPi for many months with no issues at all.

Hi asbril,

I am running both NodeLink and Polyglot on my pi and have been for quite a few months now. I am even running Motion for ip camera recording which hogs a lot of cpu all the time.

You may already do this but just in case...back up your pi3 image from the sd card before installing Nodelink. That way if by some slim chance something goes wrong you can always restore the sd card image to a previous backup and everything will be as it was before. I am sure there are plenty of sd card image programs but the one I use is Win32 Disc Manager. I make a backup of the image before any upgrades or changes to the pi which has saved me a lot of grief over the years.

Google Win32 Disc Imager and download a copy to your win10 machine. Here is the link to SourceForge. Obtain a SD card to USB drive, similar in looks to a thumbdrive with a slot for the SD card. Here is a link to one but there are many different types and styles. Have Win32 Disc Imager running when you insert the SD-USB drive into the USB slot of the computer. Type a name for the image and a location on your drive then click "Read." The image of the SD card will be written to the location you selected on your win10 machine. Its really pretty easy. If you ever need to restore your SD card to a previous image the process is pretty much the reverse. You select the image you want to restore the SD card to and hit "Write"

I should caution you however. It is possible to accidently erase or over write your SD card if you are not careful and paying attention. So, don't do like I did one time, don't be in a rush. Take the time to double and triple check the process as you are reading/writing.

Port 3000 is unusual.  That's the port that Polyglot uses.  Maybe just leave the "Port" value blank and let it use the default, or specify port 22.  That's probably the port that your RPi is listening to for SSH connections.

Yes that did it. 

Sorry to be so ignorant.... Now the terminal shows "login as" ... what should I enter ?

Default rpi login is pi and password raspberry

If these work make sure you change your password by typing passwd at the prompt

I think that I made progress, but no luck with http://$hostip:$hostport" echo . I assume that use the IP of my RPi but I have tried with both port 22 and 3000. Is there a space between the IP address and echo ? Do UI actually enter this command http://$hostip:$hostport" echo in the RPi terminal or on my PC ?

Well, almost.  You're already logged in to the terminal.  What is being referred to is for you to login to Nodelink through your web browser. 

For Nodelink, I would point my web browser to: http://192.168.1.5:8090

For Polyglot: http://192.168.1.5:3000

Same machine, just different port numbers...

Once you're logged into Nodelink with your browser, you can begin setting up your devices that Nodelink will talk to.

I have tried several times, exactly as you suggest. I have Polyglot working and open at http://192.168.86.46:3000 and tried Nodelink with http://192.168.86.46:8090 but every time I get error message that 192.168.86.46 refuses connection. I even tried with firewall de-activated but no luck either.

That probably means that Nodelink isn't running on your RPi (possibly it never started).

I don't know how the install script sets up Nodelink, but there's a good chance that it starts on boot.  It might be easiest if you reboot your RPi.  Do you know if Polyglot is set to start on boot?

EDIT: I see in the very first post that Nodelink should start upon boot: "It updates the Pi, installs mono, downloads NodeLink and sets up the startup script."

I rebooted the RPi ("sudo reboot") but still same error message

Okay, something might have not gone correctly with the script.  If you can log back on to your RPi, and type the following command at the prompt to see if NodeLink is running:

Quote

ps aux | grep NodeLink

You should get output that looks like the following:

pi@raspberrypi:~ $ ps aux | grep NodeLink
pi        4693  0.0  0.0   4376   544 pts/0    S+   14:52   0:00 grep --color=auto NodeLink
pi       32043  1.5  5.7 101436 54348 ?        Ssl  03:43  10:36 /usr/bin/mono /home/pi/Nodelink/NodeLink.exe

The last line is the important one, that's what tells you that NodeLink has a process number and is indeed running.
