Raspberry Pi new install cannot download binary

Okay, so I followed this: https://www.outagesio.com/monitor-your-internet-with-raspberry-pi-nanopi-and-other-arm-devices/

And it fails with the following:

More interesting is what's in the otm.log

Ah, I see that we have to update some articles.
Just follow the steps when creating an agent, don't follow that article please and let me know what happens.

Okay, so cleared the otm directory completely to allow for a fresh download

root@pihole:/# mkdir otm
root@pihole:/# cd /otm
root@pihole:/otm# cd ~
root@pihole:~# systemctl daemon-reload
root@pihole:~# systemctl start otm.service

Popped into the otm directory, and starter was there:

root@pihole:~# cd otm
root@pihole:~/otm# ls
starter.sh

I had cleared the otm log, after this above execution, fresh output.

OutagesIO_Support

The reason this is showing us because it is the Linux binary that is being run, not the ARM one.

There might be a bug in the new method we've started using. It seems even when you select Pi, it's giving you the Linux binary.

I can have the developer that works on this look at it tomorrow and fix it. Once it's done, I can update this post.

We appreciate your letting us know because we were not aware of this issue.

jinapatton

I'm happy to be your test bed for this fix. I already have a script wrote to wipe both logs and the /otm folder.

OutagesIO_Support

Thanks for your patience. We'll certainly fix this tomorrow and update you also.

OutagesIO_Support

Question, what hardware exactly are you using? Which version of Pi, make and model please.

OutagesIO_Support

We see that everything is fine, the service is downloading the correct binary. We suspect that the hardware is not compatible with the aarch64 ARM binary.

For a test, please download the binary directly, then make it executable, then just run it like ./arm64_otm_1_81_2401

https://downloads.echonets.com/otm/arm64_otm_1_81_2401

Let us know the make/model of the Pi and what happens when you run it manually.

Raspberry Pi 3 B+ with 10 / Buster.

240K -rwxr-xr-x  1 root root 239K Sep 11 15:57 arm64_otm_1_81_2401
root@pihole:/otm# ./arm64_otm_1_81_2401
bash: ./arm64_otm_1_81_2401: cannot execute binary file: Exec format error

I can format it to 11 / Bullseye, but if that's still too old I can grab a new one, as I run a pi-hole I'll maintain a raspberry pi for my installation.

OutagesIO_Support

The Raspberry Pi 3 B+ typically runs a 32bit operating system by default, even though the hardware is 64bit capable.

If you're using a 32bit OS, the binary cannot work.

The binary is compiled as a 64bit executable, it won't run on a 32bit OS, which is likely the cause of the error you're seeing.

Here’s how you can check:

Confirm OS architecture: Run the following command to confirm if your OS is 32bit or 64bit:

uname -m

If the output is armv7l, it’s a 32bit OS. If it’s aarch64, then it’s 64bit.

Try running this against the binary that gets downloaded;

file /otm/otm_binary

OutagesIO_Support

Sorry, I didn't' see your reply before completing mine. Yes, you would need a 64bit OS running on the device for otm to run on this.

Hope this helps to solve the mystery.

All good, cleared up for now. Ordered a Pi 5, will be here tomorrow.

OutagesIO_Support

Great, let us know how that goes. It should work no problem.

jinapatton

Alright, we're in business. Purchased a Pi 5 for the PiHole / OTM client, working grand. The Pi 3 was formatted to the latest OS, and brought up as a purely OTM client.

Should I start a new thread about moving licenses and renaming things to let this be as something searchable for others in case they see this themselves?

OutagesIO_Support

If it's s different topic, best to start a new one otherwise, it gets lost in the thread. If you don't mind :).
