У меня есть корневая файловая система (скомпилирована с помощью Buildroot). Я запускаю сервер openssh, выполнив /usr/sbin/sshd . /usr/sbin/sshd использует /etc/sshd_config для самостоятельной настройки. Параметры, включенные в /etc/sshd_config :

# This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin

# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented.  Uncommented options override the
# default value.

Я включил PermitRootLogin without-password но я все еще не могу войти. Это терпит неудачу со следующим состоянием ошибки:

PermitRootLogin without-password разрешает вход только с открытым ключом аутентификации. Установите «да», чтобы иметь возможность войти с паролем. Смотрите man-страницу sshd_config, раздел PermitRootLogin .

Изменить: Если вы уже пытаетесь войти через аутентификацию с открытым ключом, то я думаю, ваши ключи не совпадают.
