Comment (by johnstonf):

 Here is section from my server log with people trying to hack in (as
 normal) and my SUCCESSFUL Cyberduck on a mac that is working (see session
 7610), which proves it is showing in the /var/log/auth.log)... but i get
 NOTHING AT ALL when trying to connect from the mac in question (again, it
 WORKED when i first installed it , then suddenly just STOPPED, and the
 error pops up IMMEDIATELY (I don't think it is getting out past the local
 mac)... (so only 1 line of importance below)...
