ssh-copy-id Не запрашивает пароль, а перебирает ключи - как исправить (Too many authentication failures)

Наблюдаем ситуацию при попытке отправить ключ на сервер:

/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "mazalov.pub"
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
Received disconnect from ..... port 22:2: Too many authentication failures
Connection to ..... closed by remote host.

Решение

Можно использовать опции

ssh -o PreferredAuthentications=password \
-o PubkeyAuthentication=no

На самом деле достаточно использовать первую:

ssh -o PreferredAuthentications=password 

Например:

ssh-copy-id -i mykey.pub -o PreferredAuthentications=password fauser@155.155.155.155
