my-devices/sdk

macchina.io REMOTE provides secure remote access via web (HTTP), shell (SSH), remote desktop (VNC, RDP) and other protocols to IoT devices behind routers or firewalls. No port forwarding, scarce public IPv4 addresses, or complex and inflexible VPNs required. This SDK contains the Device Agent and client tools.

WebTunnelSSH failed with SSL Exception in Ubuntu 20.04 x86_64

The WebTunnelSSH failed on Ubuntu 20.04:

$ WebTunnelSSH --username=$user --password=$pw --login-name=$luser https://${id}.my-devices.net
Failed to open forwarding connection: SSL Exception: error:14161044:SSL routines:state_machine:internal error 
kex_exchange_identification: read: Connection reset by peer

There is no different in the resulting error if the the SDK is build with the installer script $ curl https://raw.githubusercontent.com/my-devices/agent-installer/master/install.sh | bash or with the GNU Make script $ ./buildsdk.sh.

Start the WebTunnelCient works but connect with ssh on the forwarded port failed with the same error:

ssh -p $port $user@localhost
Failed to open forwarding connection: SSL Exception: error:14161044:SSL routines:state_machine:internal error

Install on Amlogic S905 tv box running LibreElec

Nice project...

This could be great to access TV boxes, a big market. I am running LibreElec.tv on my Amlogic S905 TV box and the problem is that LibreElec is a read only Linux JeOS ( just enough OS) for media player KODI.

However LibreElec can install the Entware opkg package manager. So how can I install your build via Entware?

Cheers,
😁

How to enable multiple http ports to Macchina?

I would like to enable multiple ports(services) in macchina. In the configuration file, it allows me to enable one http port. Is there anyway I can enable multiple http ports services to macchina?

SSH

I was able to get my remote connection going, but I was wondering if it were possible to SSH into them. According to the FAQ, I am suppose to run WebTunnelAgent on the client. I am trying to run the Windows 10 SDK but I get a "Not found: webTunnel.reflectorURI". I would really appreciate if I could get some guidance on this. Thanks.

Race Condition in Agent may lead to first data message to arrive at server before channel open confirmation

Master Solution for Whole Repository?

Is there any reason there is not an .sln file for the whole repository?

How to generate WebTunnel Configuration file automatically?

Hi Team,
I am using Macchina Remote Manager to connect my devices and access those on cloud. To register device I am downloading configuration file on Macchina Device Dashboard. Is there any way I can automate this downloading file by hitting API? or How to generate this file by my own?

configuring the device

I am following the steps in this link https://macchina.io/blog/internet-of-things/how-to-access-and-control-your-thing-remotely-and-securely/. I got my SDK to build and finished configuring the device.
When I run ./bin/Linux/armv7l/WebTunnelAgent command, I get no such file/directory.
Is there a particular way to run this command? Or am I missing a step here?

SDK build failed

Getting a "cannot find -lz" followed by bSDK build failed error while running ./buildsdk.sh command
