Adalbert:
I just began checking as you suggest only to find that ssh is
working normally this morning! It did not work when I needed it
and as a result I lost all my Thunderbird mail files attempting
to work around the problem. Result much inconvenience and extra
work! However here we are a week later and it's working as it
should? I even tried different ethernet cables, different ports
on the ethernet switch, everything I could think of to no avail ...
Thank you for delineating a test procedure. I have copied it
into my Linux notes and will do as you suggest if/when the
problem reoccurs.
Thank you.
Bob
