Ouch.  Ouch!  That must not have been a pleasant experience in any sense
of the word.  Knowing all too well how these things tend to go, the
errors you get from the SSH log probably were very unhelpful, mostly
stemming from C's bad ole practice or returning a generic unhelpful
"failed" error code for all failures indiscriminately.  I had to work on
SSH-based code recently, and it's just ... not a nice experience overall
due to the way the C code was written.
