Hi Fedora users!
Over the last years, there were several issues in the SCP protocol,
which lead us into discussions if we can get rid of it in upstream [1].
Most of the voices there said that they use SCP mostly for simple ad-hoc
copy and because sftp utility does not provide simple interface to copy
one or couple of files back and forth and because of people are just
used to write scp rather than sftp.
Some months ago, I wrote a patch [2] for scp to use SFTP internally
(with possibility to change it back using -M scp) and ran it through
some successful testing. The general feedback from upstream was also
quite positive so I would like to hear also opinions from our users.
It still has some limitations (missing -3 support, it will not work if
the server does not run sftp subsystem, ...), but it should be good
enough for most common use cases.
Today, I set up a copr repository with the current openssh from Fedora +
the patch [2] for anyone to test and provide feedback, either here on
the mailing list, or in the github PR according to ones preferences.
I am looking for any kind of feedback from the idea through the
usability, implementation. Is this something you would like to see in
Fedora soon? Do you have something against this? Is your use case missing?
