(1) The dump1090-mutability’s init script specifies that it is controlled by user dump1090
.
(2) Th user dump1090
is created during installation of dump1090-mutability.as a system user with no home directory and no groups. You can check it by following command:
$ groups dump1090
dump1090 : nogroup
(3) In order for dump1090-mutability to be able to use DVB-T, it must be member of group plugdev
, but by default it is not. Unfortunately the maintainers of the dump1090-mutability (DEB_VER) have not yet removed this bug.
(4) To add user dump1090
to group plugdev
following commands are required:
$ sudo usermod -a -G plugdev dump1090
$ sudo reboot
Now check:
$ groups dump1090
dump1090 : nogroup plugdev
-
The engine (decoder) in both versions is more or less same, so performance wise there is not much difference.
-
Yes, the SkyView map appearance is much better than that of dump1090-mutability map, and has many more display facilities which dump1090-mutability lacks.
Please brows this thread:
Dump1090-mutability ver 1.15~dev package now available in Repository!
NOTE: The Debian package maintainers have renamed it to EB_VER
(actually DEB_VER
with D
missing due to a bug )
Nothing is broken, this is normal.The map of dump1090-mutability at port 8080
is not available. It is available at ip-of-computer/dump1090/gmap.html
.
NOTE:
-
In my previous post, after adding dump1090 to group plugdev, I have asked to restart dump1090-mutability. This in many cases is not sufficient, and a positive way is to REBOOT the computer.

To configure/reconfigure dump1090-mutability and add your Longitude & Latitude, please issue following command.
$ sudo dpkg-reconfigure dump1090-mutability
The above command will open a dialog, and ask to enter parameters/choices. Just keep on pressing ENTER key to accept defaults till you reach Latitude & Longitude questions. Here you have to enter actual values, then press Enter key. Continue pressing Enter key till the dialog closes.
At one stage pressing Enter key may not move the dialog to next stage. Press TAB key to make
<ok>
of dialog red, then press Enter key to move on.Once you have added Latitude & Longitude values, go to map
ip-of-computer/dump1090/gmap.html
and reload browser (Ctrl+F5). The map will start showing your station marker with 3 concentric rings (100nm, 150nm, 200nm). TheDistance
column in table at right of map (which was empty) will now populate with distances of aircrafts from your location.
