I am learning development with QT and have started my first project. I am running a Hypervisor based Windows OS with QT5 on it. What I want to do is when I click a button, I want to copy my linux script over to the linux side with its ip 192.168.0.200 and then ssh into root and execute the script.

Now, the problems that I am facing is, I have my GUI and application set up, but when I try to run the SCP and SSH command using system() it gives me the following error:

FOR SSH: I am ruuning system("PATH=%some path that I want to set% && ssh -T -o StrictHostKeyChecking=no root@192.168.0.200");
Its giving me: Warning: Permanently added '192.168.0.200' (RSA) to the list of known hosts
Permission denied, please try again
Permission denied, please try again
permission denied (publickey,gssapi-keyex,gssapi-with-mic,password)

FOR SCP: I am running system("PATH=%some path that I want to set% && scp -o StrictHostKeyChecking=no cygdrive/c/somepath root@192.168.0.200:/tmp/");
Its giving me: Could not create directory '/home/user/.ssh'
Failed to add the host to the list of known hosts
permission denied, please try again
permission denied (publickey,gssapi-keyex,gssapi-with-mic,password)
lost connection

I have been trying to find a solution since long. Would be really glad if someone could help me out.

Thank you in advance.
