    Sometimes I find you need to completely shut down the Pi (sudo shutdown -h now) remove the power and restart. Sometimes I still need to restart the FR24 software from within the control panel @ :8754.
    In fact as I am writing this I found although I was still online there were no aircraft being decoded - it appeared that dump1090 had stopped working as VRS on port 30003 showed nothing. Also viewing Dump1090 output direct at 8080 brought up an error webpage.

    pi@raspberrypi ~ $ service fr24feed status
    [ ok ] FR24 Feeder/Decoder Process: running.
    [ ok ] FR24 Stats Timestamp: 2015-12-21 19:45:36.
    [ ok ] FR24 Link: connected [UDP].
    [ ok ] FR24 Radar: T-EGMC14.
    [ ok ] FR24 Tracked AC: 32.
    [ ok ] Receiver: connected (44 MSGS/0 SYNC).
    [ ok ] FR24 MLAT: ok [UDP].
    [ ok ] FR24 MLAT AC seen: 0.

    So I thought I'd try:

    pi@raspberrypi ~ $ killall dump1090
    dump1090(5278): Operation not permitted
    dump1090: no process found
    pi@raspberrypi ~ $ dump1090 --net --net-http-port 8080
    -bash: dump1090: command not found

    But strangely even though it says command not found all has started working again.

    I have no idea where Dump1090 lives - it's not in the root directory and I have no ideas ??

    Anyone help ??

    Glad to hear you are working now, I seem to have a problem again with Dump1090 as this morning although I am still connected to FR24, I have no A/C and I do not see the Dump1090 web screen.

    Anyone here know the correct commands (see my last post) Like a lot of users I am a total novice with Linux.

    Thanks

    John

    Hmmm.... After writing this post everything is up and running again ???????

    hello
    i did setup a new raspberry Pi2 with USB RTL receiver, according the official FR24 instructions, sadly i always get this information:
    pi2.JPG
    i did try to find some help thru forum, and the trick with the Modprobe.d /exclusion list change is not getting me help.
    any idea?

    i'm not an expert in linux, so i don't know how to proceed!

    thank you

    Regarding the yesterday problem we had a technical issue where connections would not be authenticated properly. It resolved automatically for those of you who run more recent version of our feeding application. Others may need to stop and start it again.

    alemino: please make sure there is no other application using the SDR dongle, if this doesn't help please contact our support.

    Please plug in your USB RTL device and then post the output of
    Code:
    lsmod | grep dvb
    in a terminal.
    Note | is not a numeral "one" or letter "Ell", it is the "pipe" character, on my UK keyboard it is at the bottom left, above the \ character
