I am fairly certain the problem lies with IBM but I am no crypto expert. Is (for instance) the server rejecting the connection because (say) it does not understand ECDSA? Unfortunately I do not have an older instance of cygwin ssh to try that theory out. The failure is recent. I upgraded my cygwin instances over xmas. My primary concern is that the latter (linux) connection (after ~~~) may fail after a future upgrade.
