Manual Install of dump1090-fa on Fedora 28, x64_86 (Intel PC)

FlightAware ADS-B Flight Tracking
1

I faced two issue, one resolved, other still un-resoved

  1. Dump1090-fa failed to start by systemctl, both at boot and by manual command. I solved it by commenting out line User=dump1090 in file dump1090-fa.service. I dont understand why as I have created user dump1090 by command sudo adduser --system dump1090. Please see details below. Oliver @obj may shed some light.

  2. Lighttpd integration of dump1090-fa is giving headaches. I followed the same method as I have used for Debian 9.5 x86_64, which work ok on Debian, but no success on Fedora28 x86_64.

(1) ENABLED SSH AND INSTALLED NANO

sudo dnf install openssh-server
#Package openssh-server-7.7p1-2.fc28.x86_64 is already installed, skipping.
sudo systemctl enable sshd.service
sudo dnf install nano

(2) INSTALLED PACKAGES TO FULFILL DEPENDENCIES & TOOLS TO BUILD

sudo dnf install libusb-devel   
sudo dnf install ncurses-devel  
sudo dnf install rtl-sdr
sudo dnf install cmake

(3) BUILT LIBRTLSDR FROM SOURCE (FEDORA REPOSITORY DOES NOT HAVE IT)

sudo mkdir ~/build-librtlsdr   
cd ~/build-librtlsdr  
sudo git clone https://github.com/steve-m/librtlsdr.git   
cd librtlsdr  
sudo mkdir build && cd build  
sudo cmake ../  
sudo make  
sudo make install 

sudo cp /usr/local/lib/pkgconfig/librtlsdr.pc  /usr/share/pkgconfig/librtlsdr.pc

(4) BUILD DUMP1090-FA EXECUTEABLE FROM SOURCE CODE

sudo mkdir ~/build-dump-fa  
cd ~/build-dump-fa  
sudo git clone https://github.com/flightaware/dump1090.git  
cd dump1090  
sudo make BLADERF=no

(5) ADDED MISSING RTL-SDR.RULES

sudo wget -O  /etc/udev/rules.d/rtl-sdr.rules "https://raw.githubusercontent.com/osmocom/rtl-sdr/master/rtl-sdr.rules"   

sudo reboot

(6) TESTED

cd ~/build-dump-fa/dump1090
sudo ./dump1090

(7) CONFIGURATION

sudo adduser --system dump1090 

sudo cp -r ~/build-dump-fa/dump1090/dump1090  /usr/bin/dump1090-fa  
sudo cp ~/build-dump-fa/dump1090/debian/dump1090-fa.default /etc/default/dump1090-fa  
sudo cp ~/build-dump-fa/dump1090/debian/dump1090-fa.service  /lib/systemd/system/dump1090-fa.service  
sudo systemctl enable dump1090-fa.service  



sudo reboot

Did not succeed yet. Facing many issues. Will post method when succeed to resolve issues.

I would guess it is a permissions problem, you may need to add the dump1090 user to a special group (“plugdev”, possibly) to get access to the rtlsdr USB device.

Thanks Oliver for the tip.
Right now I am away from my computer, will try it tonight or tommorow.

ATTEMPT-1:

I did not find any group named “plugdev” in fedora when I listed all groups by following command

[abcd@fedora ~]$ cut -d: -f1 /etc/group | sort 

abcd
abrt
adm
apache
audio
avahi
bin
brlapi
cdrom
cgred
chrony
colord

However I found group “audio”, and added it to “dump1090” by following command

[abcd@fedora ~]$ sudo usermod -a -G audio dump1090

[abcd@fedora ~]$ groups dump1090
dump1090 : dump1090 audio

.
Un-commented line User=dump1090, and rebooted.
Checked status of dump1090-fa, found FAILED
.

ATTEMPT-2

Listed devices, found dvb listed there, with owner root and group root.

Added group root to user dump1090

[abcd@fedora ~]$ sudo usermod -a -G root dump1090
[abcd@fedora ~]$ sudo reboot

After reboot, checked dump1090-fa status, FAILED

FINALLY in file /lib/systemd/system/dump1090-fa.service commented out line User=dump1090, and it is working ok.

That’s because without the user line, you’re running it as root, which is not a great idea.

You’ll need to dig into /sys and see what the permissions on the USB bus devices are

SUCCESS!

First thank you @obj for help and guidance. I really appreciate it.

Here is what happenned:
it was an oversight that I missed rtlsdr in groups list.
Just after posting my last post, I reviewed the groups list again and caught rtlsdr.

[abcd@fedora ~]$ sudo usermod -a -G rtlsdr dump1090

[abcd@fedora ~]$ sudo nano /lib/systemd/system/dump1090-fa.service
#UN-COMMENTED LINE "User=dump1090"

[abcd@fedora ~]$ sudo systemctl daemon-reload
[abcd@fedora ~]$ sudo systemctl restart dump1090-fa
[abcd@fedora ~]$ sudo systemctl status dump1090-fa -l

Took further steps to remove unnecessary groups, leaving only groups dump1090 and rtlsdr.
Rebooted, and checked status.

[abcd@fedora ~]$ groups dump1090
dump1090 : dump1090 audio root rtlsdr

[abcd@fedora ~]$ sudo gpasswd -d dump1090 root
[abcd@fedora ~]$ sudo gpasswd -d dump1090 audio

[abcd@fedora ~]$ groups dump1090
dump1090 : dump1090 rtlsdr

[abcd@fedora ~]$ sudo reboot

.
.
Status after reboot, working OK.

[abcd@fedora ~]$ sudo systemctl status dump1090-fa -l
