Как уже упоминалось @manojlds, вы можете копировать SSH-ключи.Я лично делал это на машинах разработки.
Кажется, что время соединения связано с тем, что ssh-daemon не запущен.Чтобы убедиться, что вы можете подключиться к машине, пожалуйста, запустите следующую диагностику
ps -ef | grep sshd
Вы должны получить
root 726 1 0 08:07 ? 00:00:00 /usr/sbin/sshd -D
Если запущен sshd, дважды проверьте разрешения на ваших ключах и принудительно установите в0700.
cd .ssh
chmod -R 0700 * #Read only to the user only
Попробуйте запустить ssh -v <user>@<host>
, если вы получите
ssh -v 192.168.0.150

, значит, есть проблема с вашим sshdaemon, потому что первоначальное рукопожатие не удалось.Успешное общение выглядит так:
