General Questions and Answers / remote execution of QuantumATK scripts for Windows

« on: June 15, 2021, 10:42 »

Hi everyone,

I am recently trying to setup remote execution of QuantumATK scripts within two Windows computers. However, I've faced some problems while setting up the remote machine. It says that a bash shell binary does not exit on the server in the Diagnostics in Machine Settings. Although I tried to install bash from Windows Subsystem for Linux package and Ubuntu on my server computer,  it stills doesn't work.

Could anyone teaches me more about this, or suggested me any other method to get thru this problem?

Thanks in advance for any help.

After some investigation, I found that it is the problem of Default shell of OpenSSH.

• Using powershell.exe as default, I will just get stuck with the error of bash shell binary doesn't exit on the server in the Diagnostics in Machine Settings with the sshd logs:

• Using bash.exe as default, I would be able to have all checks in the Diagnostics but get stuck at the Copying file phase. The reason is bash.exe isn't working with sftp-server.exe properly. Here attached with the sshd logs:
