SSH connection failure between Qt Creator and Linux Device

[maher_electronic]

Hello,

I'm trying to connect Qt Creator with a Beaglebone Black, but when I test connection between host and target I get an error message that says SSH connection failure.

My host is a PC with Ubuntu 14.04 and Qt Creator 3.0.0.
My target is a Beaglebone Black with Debian 9.5.

The connection between QtCreator and the target is set to use a password. The connection via terminal between host and target is ok (ssh root@192.168.7.2).

The first time that I try to communicate host and target I get the following message:

If I close Qt Creator and open it again then I get the following message:

However, communication between the host and a Beaglebone Black with Angstrom works perfectly.

Could someone help me solve this problem?. Thanks.

Hi,

You should check the version of OpenSSH on your device. There might be a configuration issue with regards to the protocols available on your target and the one authorized on your host.

Hello SGaist,

Version of OpenSSH on host => OpenSSH_7.4p1, OpenSSL 1.0.1f 6 Jan 2014
Version of OpenSSH on target => OpenSSH_7.4p1 Debian-10+deb9u7, OpenSSL 1.0.2l 25 May 2017

Thanks.

Hi @maher_electronic,

are you really limited to such old program versions?

• Ubuntu 14.04 is no longer supported, 20.04 is just around the corner
• Creator 3.0.0 is also quite old, we have seen 16 major releases since then

Regards

Hello aha_1980 ,

I'm using old versions because I compiled Qt 4.8.5 libreries for Beaglebone Black with Angstrom 5 years ago and I have continued using these versions.

Now I have decided to try a newer operating system for Beaglebone Black because I want to solve a problem that I have detected in my project.

Thanks.
