Как я могу установить успех соединения ssh на все времена?
Я делаю удаленную связь с моим Raspberry Pi, используя SSH.
Большую часть времени я могу подключиться. Но иногда я получаю ошибку соединения, так как "сессия не работает".
Иногда "в соединении отказано". Почему у меня такая ошибка соединения, и мне нравится иметь соединение почти на 100%. Теперь я часто получаю эту ошибку. Я искал и обнаружил, что мне нужно проверить мой sshd_config и запустить ps -ax | grep ssh .
Мой ps -ax | grep ssh вывод
pi@raspberry ~ $ ps -ax | grep ssh
warning: bad ps syntax, perhaps a bogus '-'?

# Set this to 'yes' to enable PAM authentication, account processing,
# and session processing. If this is enabled, PAM authentication will
# be allowed through the ChallengeResponseAuthentication and
# PasswordAuthentication. Depending on your PAM configuration,
# PAM authentication via ChallengeResponseAuthentication may bypass
# the setting of "PermitRootLogin without-password".
# If you just want the PAM account and session checks to run without
# PAM authentication, then enable this but set PasswordAuthentication
# and ChallengeResponseAuthentication to 'no'.
