It's a machine running on Amazon's AWS some ordered only this year.  But
our IT has ordered RHEL 7, which is quite old.  I don't know the reason,
probably price or maintenance fees...

Sure, I can use my private Debian server.

Yes, but maybe we'll find the root course of the plinkx problem. :-)

But when it is an openssh implementation why do you need to distinct ssh
and sshx?  Doesn't the MS version know to use ~/.ssh/config?

On my Windows machine is openSSH already installed.  I'll have a look
and report the results next week.

PS: I lately copied some 250 images from a remote (Linux) server to my
local machine (Linux).  The files ranged from 1 MB to 60 MB.  After a
certain size (I think around 10 MB) Tramp is asking if one really wants
to copy such a large file.  Is there a custom variable to avoid such
queries?  Or couldn't you implement these nifty questions like ""yes
[y], no [n], yes to all [!]"?  Otherwise one has to wait for the whole
series to confirm the copying of individual files...
