Maybe something has changed? http://sourceware.org/ml/cygwin/2005-10/msg00672.html http://sourceware.org/ml/cygwin/2005-11/msg00732.html Anyone else see this or know how I can get around this? Key-auth can be done on those hosts that it's feasible for all other laziness I'll have to try to see if I can get this work.... Thanks Cygwin, Dennis O.
