Commands to determine OS.png

Init-function is available in Debian based OS. Seems it is missing from your OS. You can add it by following commands.

After adding init-function, run the command "sudo fr24feed-status"

Code:

sudo mkdir -p /lib/lsb  

sudo wget -O /lib/lsb/init-functions "https://github.com/abcd567a/fr24feed-Fedora-OpenSUSE-CentOS-amd64/raw/main/fr24/init-functions"

If you want to see the contents of init-functions file which will be downloaded to your NASDS118 Synology (ARM64) computer's directory "/lib/lsb/", click this link:

Thanks, I can now execute fr24feed-status. It seems the first check there already fails: Process . . . Failed!

I also checked which services are running using "systemctl --type=service" and can see the following: fr24feed.service loaded failed failed Flightradar24 Decoder & Feed

I figured maybe something during the installation was incomplete, and when I install the package again I get the following output:

/usr/lib/fr24/fr24feed_updater.sh: line 13: apt-get: command not found
/usr/lib/fr24/fr24feed_updater.sh: line 14: apt-cache: command not found

Seems like I'm missing some dependencies. Would you happen to have these as well?

Seems your OS is NOT a Debian-based OS. I am not sure, but think name of the OS which is installed on your DS118 Synology (ARM64) is Linux named DSM7

If you receive a "command not found" message when trying to run an apt command (such as "apt" or "apt-get" or "apt-cache"), the first thing to consider is the Linux distribution you are using.

The "apt" is a software package management tool for Debian or Debian-based Linux systems, and is not available in many other Linux OS, such as Fedora, Red Hat, CentOS, OpenSuse, etc, etc.

(1) Please tell us how you installed fr24feed 1.0.34-0.

(2) Please post output of following command

Code:

sudo find / -name fr24feed.service

**rroos** · 2023-03-21, 09:40

Really appreciate your help on this.

For context, here's what is running: Linux vault 4.4.180+ #42962 SMP Tue Jan 31 23:16:54 CST 2023 aarch64 GNU/Linux synology_rtd1296_ds118 (upon executing uname-a)

For context, initially I tried using fr24feed 1.0.23-8 by manually unpacking the .deb file and registering the service myself. That didn't seem to work as I would get an error on executing "sudo systemctl start fr24feed".

I therefore opted to go for the latest version and install the package using "sudo dpkg -i fr24feed_1.0.34-0_armhf.deb"
With that version installed, I could actually run "sudo systemctl start fr24feed" without errors, however subsequently checking fr24feed-status shows that the service while loaded isn't active or running.

When I run "sudo find / -name fr24feed.service" I get the following.

/opt/fr24feed/fr24feed_1.0.23-8_armhf/etc/systemd/system/fr24feed.service
/volume1/@Entware/opt/fr24feed/fr24feed_1.0.23-8_armhf/etc/systemd/system/fr24feed.service

Good.

TRY THIS:

(1) In "/etc/systemd/system/fr24feed.service" file, disable User=fr24 and Group=fr24 by placing # at start of line, as shown in red above.
(2) Save file
(3) Give following commands

Code:

sudo systemctl daemon-reload  

sudo systemctl restart fr24feed  

sudo systemctl status fr24feed  

sudo fr24feed-status

**rroos** · 2023-03-22, 12:34

First two commands work without issue. The 3rd command has significantly improved as the ExecStart='usr/bin/fr24feed now runs. I still get errors though

Upon running "sudo systemctl status fr24feed" I now get:

Code:

● fr24feed.service - Flightradar24 Decoder & Feeder
Loaded: loaded (/etc/systemd/system/fr24feed.service; enabled; vendor preset: disabled)
Active: activating (auto-restart) since Wed 2023-03-22 22:13:38 AEST; 742ms ago
Process: 20926 ExecStart=/usr/bin/fr24feed (code=exited, status=0/SUCCESS)
Process: 20920 ExecStartPre=/usr/lib/fr24/create_missing_directories.sh (code=exited, status=1/FAILURE)
Process: 20914 ExecStartPre=/usr/lib/fr24/unregister_kernel_modules.sh (code=exited, status=0/SUCCESS)
Process: 20906 ExecStartPre=/usr/lib/fr24/install_dump1090.sh (code=exited, status=127)
Main PID: 20926 (code=exited, status=0/SUCCESS)

So I had a look at the "create_missing_directories.sh" and it fails on the last command in that script which gives me

Code:

chown: invalid user: ‘fr24:fr24’

Sounds like that has something to do with what I just outcommented. How should I update that .sh file?

The "install_dump1090.sh" seems to fail because it wants to install dump1090 again. That's weird because I have that installed through entware and it exists in "/opt/bin/dump1090", which is reflected in my /etc/fr24feed.ini file. So according to the comments in the .sh file it should look for my version of dump1090 but it doesn't do that. I actually don't understand how the script knows to look in a different folder. It seems hardcoded to look in /usr/lib/fr24/dump1090 ?

I tried to be clever and commented out the ExecStartPre=-/usr/lib/fr24/install_dump1090.sh in the fr24feed.service file but still no luck.

**abcd567** · 2023-03-22, 13:26

While manually installing fr4feed, you did NOT create user fr24, that is why fr24feed.service faied to start. When you commented out "User=fr24", the service now started by user "root".

Also command chown failed because user fr24 does not exist

Create user fr24 by following command:

Code:

sudo useradd --system fr24

After creating user fr24, remove both # you have put in file "fr24feed.service" on my instructions in my last post, save file, then give following commands again

Code:

sudo systemctl daemon-reload

sudo} systemctl restart fr24feed

sudo systemctl status fr24feed

sudo fr24feed-status

}

**rroos** · 2023-03-23, 10:41

Ok so creating the group and user made sure that the chown command worked. The service however still doesn't seem to work.

Upon the command 'sudo systemctl status fr24feed' I now get

Code:

● fr24feed.service - Flightradar24 Decoder & Feeder
Loaded: loaded (/etc/systemd/system/fr24feed.service; enabled; vendor preset: disabled)
Active: activating (auto-restart) since Thu 2023-03-23 20:15:39 AEST; 75ms ago

Process: 10254 ExecStartPre=/usr/lib/fr24/unregister_kernel_modules.sh (code=exited, status=0/SUCCESS)

Main PID: 10266 (code=exited, status=0/SUCCESS)

That's not surprising as the script is looking for dump1090 in /usr/lib/fr24/dump1090 whereas my dump1090 lives in opt/bin/dump1090.

If I change the script to look in that location, the error on the script is gone as expected, but the service still doesn't work. I can't seem to find a log file with more detailed info. When I run "systemctl" I can see that the service is loaded but not active or running (both are shown as failed).

Should I copy my dump1090 installation to /usr/lib/fr24/dump1090 ? It's odd because if I simply run sudo fr24feed, the application works?

The dump1090 in /usr/lib/fr24/ is only a soft link (also known as symlink) to the actual binary wherever it is located.

My binary's physical location is:
/usr/bin/dump1090-mutability

(1) Which decoder you have installed?

(2) Please post output of following command.
Note: Replace fr24key value by xxxxxx when posting in forum

Code:

cat /etc/fr24feed.ini

(3) What is output of command shown in screenshot below?

In file "/etc/fr24feed.ini" change

to
logmode="1"

Save file, restart fr24feed, then check log

**rroos** · 2023-03-25, 01:22

Ah thanks, I fixed that symlink that didn't exist.

1. The decoder I have installed in dump1090, which I installed via Entware. I'm running dump1090-fa 4.0.

2. cat /etc/fr24feed.ini gives me

3. ls -l /usr/lib/fr24 gives me (and yes, I created the dump1090 here manually)

4. Unfortunately, starting the service doesn't create a log file. I do get a log file when I manually run 'fr24feed'....
