Ziti-edge-tunnel binary for Teltonika RUT956 unable to connect with Openziti controller after successfully built

Tunneler Apps Ziti Edge Tunnel
1

I've successfully built ziti-edge-tunnel binary to run inside Teltonika router RUT956. My original source of info was this Netfoundry blog: https://support.netfoundry.io/hc/en-us/articles/4413015431949-NetFoundry-for-Zero-Trust-IOT-Edge-embedded-Networking

After that, I've tried to connect to my openziti controller. In the meantime every tunneler has successfully connected: macOS, Linux, Windows. But ziti-edge-tunnel is unable to enroll the JWT identity from the controller.

This is the error message:

I know troubleshooting like this could be hard, so I need help for how to document this case and which part of the compilation, maybe like:

  • SDK version

  • Target

  • Toolchain version

  • TLS: mbedTLS version

  • ziti-tunnel-sdk-c version

I'm not looking for easy/magical way to troubleshoot this case, but I'm willing to help someone in this forum who would like to give me the systematic way to solve this problem. But if any of you who already has tested Teltonika RUT956 ziti-edge-tunnel binary which successfully enrolled and run the openziti tunnel, and can give me the file & dependencies to tried it out, I'm more than welcome.

Hi @affanzbasalamah, welcome to the community and to OpenZiti!

My guess is that you're hitting some kind of bad crypto type error. (i edited your post btw for clarity). Can you try running the tunneler with something like:

ZITI_LOG="6;tlsuv=6" ziti-edge-tunnel run -i tlsuv.json 2>&1

For example you should get a lot of extra debugging:

$ ZITI_LOG="6;tlsuv=6" ziti-edge-tunnel run -i tlsuv.json 2>&1 | grep "tlsuv\:"

Thanks Clint for your response.

After see your example, I tried to enroll the identity in other Linux VM, and use the identity with ziti-edge-tunnel run command. The command generate lots of logs and running on loop. I give you the snippet below:

Do I need to provide configuration & logs from the controller (that I've set up myself), and which one?

Best regards,

Affan

Is there any chance that you have endpoint protection software running or something that might get in the way of that handshake completing?

(6071)[ 28.883] VERBOSE tlsuv:http.c:391 httpzerotrust.salamahsystems.com:1280: starting TLS handshake

(6071)[ 35.237] WARN tlsuv:http.c:463 httpzerotrust.salamahsystems.com:1280: connection timed out

seems pretty odd to me. On your controller, are there any logs that are useful at the time you perform this operation?

On your 'regular' machine, are you able to enroll an identity (not on the RUT956)? let's take your build out of the equation and just make sure OUR build of ziti-edge-tunnel is able to work against your controller first to reduce the parts we need to focus on.

If stock (provided by us) ziti-edge-tunnel works, well we'll know that it's somehow entirely your build that is the problem.

This is the log for root@RUT956:~# ZITI_LOG="6;tlsuv=6" ziti-edge-tunnel run -i /tmp/rut956-claude.json 2>&1 | grep "tlsuv:" , I've put it in here: log of ziti-edge-tunnel with tlsuv filter - Pastebin.com

the regular log still ends at segfault:

I noticed that you're building with mbedTLS(v2.28.9).
We are no longer supporting that (and mbedTLS v2.x versions are out of support).
You should change your build to use OpenSSL.

Thank you Eugene for your help,

I've been using this script to build https://raw.githubusercontent.com/netfoundry/iot_build_scripts/main/build_teltonika.bash and it still using mbedTLS.

Give me the clue how to update it using OpenSSL?

Thanks!

Dear @TheLumberjack and @ekoby, @PhilipGriffiths emailed me few days ago and tell me to use the methods from this Github: https://github.com/NicFragale/NetFoundry/tree/main/Utilities/OpenZITI-OWRT

And I've successfully compiled it, and it managed to enroll the identity and run the tunneler using the identity. Right now the RUT956 SSH and web GUI management can be accessed from Openziti client, and service at the same LAN can also be advertised through Openziti.

Thank you so much for your generous help,

Affan

Hi, I also tried to build OpenZiti for Teltonika RUT206 (RUTE_R_00.07.23) but not succeed.

Here is what I did

# quide says tested on Ubuntu 22.04, but it has  too old CMAke version...
docker run -it ubuntu:24.04
apt update && apt install git -y
git clone https://github.com/NicFragale/NetFoundry.git
cd NetFoundry/Utilities/OpenZITI-OWRT/
# RUT206 cat /etc/os-release
# VERSION="21.02.0"
# OPENWRT_BOARD="ramips/mt76x8"
bash OWRT_Builder.bash "21.02.0" "ramips" "mt76x8" "latest"
