Mosquitto 在使用 CRL 文件时阻止所有连接

Question

我在 linux 服务器上托管 MQTT 代理。到目前为止，none 的 MQTT 客户端在连接 (sub/pub) 时遇到任何问题，直到我在 Mosquitto 配置文件中添加了“crlfile”行。当我在配置文件中设置“crlfile”时，none 的客户端可以连接。奇怪的是 CRL 文件实际上没有撤销证书。但是，所有客户端都会出现此错误：

Error: The connection was lost.

我正在使用 Mosquitto 2.0.12，这是我的 Mosquitto 配置文件：

# For listener with port 1883
#listener 1883

# Set 8883 as the listener (port)
listener 8883

# Path to the password file
#password_file /etc/mosquitto/passwords

# Path to the cafile
cafile /etc/mosquitto/certs/ca.crt

# Path to the broker cert file
certfile /etc/mosquitto/certs/broker.crt

# Path to the broker key file
keyfile /etc/mosquitto/certs/broker.key

# Path to the CRL file
crlfile /etc/mosquitto/certs/ca.crl

# Whether a certificate is required to connect (Set to true for TLS)
require_certificate true

# Allow anonymous connection (Set to false for TLS)
allow_anonymous false

# Path to Dynamic Security Plugin
plugin /usr/lib/x86_64-linux-gnu/mosquitto_dynamic_security.so

# Path to Dynamic Security config file
plugin_opt_config_file /etc/mosquitto/conf.d/dynamic-security.json

# Whether each listener has the same settings
per_listener_settings false

我设法解决了这个问题。 CRL 文件是使用 Python 的加密库生成的。问题是，当我设置上次更新和下一次更新日期时间时，我使用本地时间设置了它，而我应该根据 UTC 时间设置它。所以我改变了我的代码

crl_builder = crl_builder.last_update(datetime.utcnow())
crl_builder = crl_builder.next_update(datetime.utcnow() + timedelta(days=365000))

至

crl_builder = crl_builder.last_update(pytz.utc.localize(datetime.utcnow()))
crl_builder = crl_builder.next_update(pytz.utc.localize(datetime.utcnow()) + timedelta(days=365000))

现在我的 Mosquitto 经纪人工作正常:)
