Tool/software:
I have noticed much of the SDK documentation & the Linux Academy uses scp for file transfers.
"According to OpenSSH developers in April 2019, SCP is outdated, inflexible and not readily fixed; they recommend the use of more modern protocols like SFTP and rsync for file transfer. As of OpenSSH version 9.0, scp client therefore uses SFTP for file transfers by default instead of the legacy SCP/RCP protocol."
We should use one of the other 2 protocols.
