Dump1090 mutability 1-15 on Mint linux

[wiedehopf]

Yeah when you stop the service and run it on the console in interactive mode it won't provide the data for the webinterface.

First try this:
Clear Browser Cache (Ctrl+Shift+Delete) and Reload Browser (Ctrl+F5)

If you still get the warning "maybe dump1090in no longr running", then try this:

# List all the running instances of dump1090-mutability
pgrep -l dump1090

# Stop all instances of dump1090-mutability
sudo killall dump1090-mutability
sudo killall dump1090

# Restart single instance of dump1090-mutability
sudo systemctl restart dump1090-mutability

Open browser and point to
localhost/dump1090/gmap.html

Clear Browser Cache (Ctrl+Shift+Delete) and Reload Browser (Ctrl+F5)

I blacklisted Ubuntu's support for RTL-SDR DBV stick and re-booted. Now dump1090 seems to be running. I can see about 35 flights on terminal console. But still no planes on map.

Problem fetching data from dump1090.
AJAX call failed (error: Not Found). Maybe dump1090 is no longer running?
The displayed map data will be out of date.

May be wrong port number(s)?

Something is happening beyond my control. As I was closing some browser pages I realized the web display - be it lighttpd or gamin - is working!

I see Open Street Map, Switzerland centered, no planes. and this message:



I got to leave my desk right now, will be back in a few hours.

gamin is nothing to do with lighttpd, but another program/addon that has files in it needed to run lighttpd on non standard linux (Mint) that are missing things

And as such, is needed for lighttpd to start. So that confirms the web server (lighttpd) is now working - this also works independently of Dump1090

Which is why I mentioned with the dump1090 error occurring, You won't get any data, unless dump1090 is the sole USB stick user.

The give away is aybe dump1090 is no longer running?

Don't even touch lighttpd now until you can confirm you are even getting data it can use. However the earlier fix should have sorted it from not starting. You can still run the command wiedehopf suggested (and I) to restart lighttpd and see if it starts now.

But the whole thing won't go if dump1090 doesn't too

You need to understand what you are attempting to do (somewhat explained in abcds guide) vs just following commands here and there.

They are all separate programs

Dump10900-mutability - connect to stick, read data

lighttpd - create server, allow files made by dump1090 to view in web browser


If dump1090 cant run, And lighttpd cant start. You won't be going far at all.

So you need to work out why dump1090-mutability can't access the USB stick. Or find it's correct running status as it is, right now.

And once that is working. See if lighttpd can now restart with the earlier fix, and show the traffic it is getting on a webpage.

[wiedehopf]

lighttpd needs gamin to work.

so install both.

Anyway the usb_claim error occurs when another copy of dump1090-mutability or another dump1090 variety is already running.
(Or by using the receiver wiht other software)

If you get that error you can check if dump1090 is still running with this command:

pgrep -fa

But that interactive thing was just to make sure dump1090 is working, not about the webpage.

I don't have installed FR24feed on this laptop.

from https://bugs.launchpad.net/ubuntu/+s.../+bug/1453463:

FIX:
sudo apt-get install gamin

Please, add dependency of "gamin" to "lighttpd" package or remove dependency of gamin from lighttpd code.
Bug Watch Updater (bug-watch-updater) on 2019-02-23
Changed in lighttpd:
status: Unknown → Fix Released

What does this mean to me? Would it make sense to apt remove lighttpd and then apt install lighttpd again? Ot both lighttpd and gamin?

[Oblivian]

USB device in use. So either it didn't stop per the first line (sudo service dump1090-mutability stop), or you also have the FR24feed bundle/separate USB hoggging package installed taking over as soon as it does.

[Space Pilot]

sorry replying out of phase:

sudo service dump1090-mutability stop
sudo dump1090-mutability --interactive

usb_claim_interface error -6
Error opening the RTLSDR device: Device or resource busy

[Oblivian]

ok, let's give Mint another try.

apt install gamin

what next? How should I start it?

sudo service lighttpd restart

And then repeat

[Oblivian]

As for testing if dump1090 is fine.

sudo service dump1090-mutability stop
sudo dump1090-mutability --interactive

It will soon tell you if it's working with the stick

Ok, I see, dump1090-mutability is not for Linux Mint. I'll be back with RPI questions shortly :-)

Thanks for your patience.

ps
first RPI question: I've got an old Raspberry Pi 1 B with Raspbian Stretch installed and maybe an FR24 feeder of that time. Is the Pi 1 B still good enough for dump1090-mutability?

Huh?

Did you follow abcd4567 link earlier - Dump1090 is obviously working on Mint? That is reasonably cross platform. But your latest issue is the web page hosting dump1090s web portal isn't it. And I linked to a page that shows why, and the commands/other users who have experienced it and installed gamin
