    Hi there,
    I'm very new to all this, i'm trying to get FR24 to work with my Pi but it gives me this after the command "FR24AUTHIP=83.140.247.20 ./fr24feed_arm-le_233s --fr24key=YOUR_SHARING_KEY":

    -bash: ./fr24feed_arm-le_233s: Permission denied

    When I start it with the sudo I will get:

    sudo: ./fr24feed_arm-le_233s: command not found

    Any ideas how to fix this?

    Thanks guys!

    Hi Robert,

    Does this happen when you run fr24.sh script, or are you doing the commands manually perhaps?
    You need to be in the right directory to execute them.
    I see you posted colons ( not sure if that is what you are giving the Pi, or just typing it here for clarity ?

    Part of my fr24.sh:

    cd /home/pi/dump1090
    /home/pi/dump1090/dump1090 --enable-agc --modeac --aggressive --net-http-port 8090 --net --net-sbs-port 30003 --quiet --lat -27.912 --lon 25.162 > /dev/null &
    cd ~
    export FR24AUTHIP=83.140.247.20
    /home/pi/fr24feed_arm-le_233s --fr24key=7my-key-here > /tmp/fr24feed.log &

    Hi Robert,

    Did you find this (now long) thread - http://forum.flightradar24.com/threa...e-to-feed-FR24

    Generally it has everything you need on the first page - the rest is mainly discussions about problems people have had ... mostly where things haven't quite worked correctly, but usually relating to factors other than the basic software setup.

    ---

    Should you keep having problems, it might be good to set aside your pi SD card use another than do the install starting from installing the the Rasparian Wheezy image (not the pre-built ... not that there's anything wrong with it )

    This takes you through everything you need and explains why we're doing it and can remove some of the mystery that surrounds Linux.

    To build from nothing will take 1 1/2 - 2 hours.

    Question Linux Newbie questions

    I dunno if this is the right place to ask for this question, but since my decoder is Raspberry-Pi based, there it goes:

    I managed to install fr24 package and make it run. I've edited the startup scripts only fr24 after start (since dump1090 is already powered up per instructions stated in http://www.satsignal.eu/raspberry-pi/dump1090.html. I also added this to crontab:

    Code:
    @reboot sleep 5;/etc/init.d/fr24feed.sh            ## calling the startup script
    0 */2 * * * /etc/init.d/fr24feed.sh                ## restart every two hours
    My fr24feed.sh is as follows:

    Code:
    #!/bin/bash
    ### BEGIN INIT INFO
    # Provides: fr24
    # Required-Start: $remote_fs $syslog $time
    # Required-Stop: $remote_fs $syslog $time
    # Should-Start: $network
    # Should-Stop: $network
    # Default-Start: 2 3 4 5
    # Default-Stop: 0 1 6
    # Short-Description: Start 1090dump and fr24 at boot time
    # Description: Start the RTL-SDR decoder and FlightRadar24 feeder at boot
    ### END INIT INFO
    #
    #updated 2013-08-29 - write /tmp/fr24feed.log
    #updated 2013-09-23 - Add INIT INFO section supplied by Jayant
    #
    #make sure fr24feed and dump1090 software are not running
    #
    killall fr24feed_arm-le_233s
    #
    #start dump1090 we dont want output so throw it into a black hole
    # (the null device)
    #the symbol at the end of the line says dont wait for this to finish, just move
    # onto  the next command
    #
    #start the fr24 feeder(use you own key)
    #log output to /tmp/fr24feed.log ... this is actually im memory
    #create a new file each time we start
    #view the file using tail -f /tmp/fr24feed.log
    #(dont do this with dump1090 ... too much output ... will fill memory)
    #
    #
    export FR24AUTHIP=83.140.247.20
    /home/pi/dump1090/fr24feed_arm-le_233s --fr24key=----mykey---- > /tmp/fr24feed.log &
    (Yes, I've moved fr24feed_arm-le_233s to the dump1090 directory)

    I edited the crontab as root and by using ps aux | grep fr24 I got that root is the owner of this process, after a fresh restart. So far, so good. So, my questions are:

    1) Will the fr24 app start every two hours as root, since I edited crontab as root ?
    2) I noticed that with no traffic my feed appears as offline on the Your Account page. Is that correct ?
    3) Is there any order of preference for choosing a feed (i.e. FR24 receivers x RTL-RPI ones) ?

    Sorry for such a bunch of basic questions, but I am totally new in here. Am I doing things ok or am I screwing up things ?

    My feed is available at http://sbfiadsb.no-ip.org.

    Any help will be much appreciated.

    The fr24 feed software talks to dump1090 using tcp/ip so as long as both are running on the same machine (localhost), the actual account used shouldnt matter. I dont know if there is a parameter in the fr24 feed that allows you to access dump1090 on another machine.

    Cron should work as root, to check what fr24 feed is doing examine /tmp/fr24feed.log

    The sleep at the start of the @reboot line was to ensure tcp ip (give it time) was ready when we started dump1090 & fr24feed people using wifi might need to increase the delay.

    If you still have problems, consider rebuilding the software on another sd card ... that alows you to revert to the present config at any time by just swapping the card back.

    It is working as it should, but FR24 didn't use any packet of mine yet - at least I didn't see any yet. Are FR24 receivers preferred over RTL+RPI ones ?

    You have to make sure the PI is set on timezone UTC. Adjust your time to that and make sure its reports your current time minus time zone difference.
    In my case, when I type in DATE:
    pi@raspberrypi ~ $ date
    Thu Nov 28 09:02:35 UTC 2013


    ... with my timezone being +2, indeed local time now 11:02

    Its all to do with how many other receivers/feeder stations there are. The F-feeders do have a faster processing and upload time than the T- feeders, but if its only you that have an AC, sure your data will be used and displayed.
