Я пытаюсь подключить рабочий стол (win7 x64) и note (debian wheezy x32). Сделал стандартную установку из ssh cygwin и debian. Создал ключ публикации и переместил его через usbflash в ~/.ssh/authorizwd_keys
и в ~/.ssh/
В cygwin сделал
cd ~/.ssh
chmod 700 id_rsa
Чем пытаться подключиться и иметь лог
debug1: ssh_ecdsa_verify: signature correct
debug1: SSH2_MSG_NEWKEYS sent
debug1: expecting SSH2_MSG_NEWKEYS
debug1: SSH2_MSG_NEWKEYS received

UPD Проверены права доступа к файлам, измените LogLevel на DEBUG. Чем я пытаюсь подключиться, но в журнале ничего не пишется только информация о сервисе перезагрузки

UPD попытался соединиться с командой "ssh -vvv" в cygwin и увидел штрихи
"debug3 Incorrect RSA1 identifer"
"debug3 Couldnt load "/home/A/.ssh/id_rsa" as RSA publick key"
