У меня есть простой сервер MQTT Mosquitto, работающий на моем Raspberry Pi в локальной сети, и машина Windows с простым приложением java в Eclipse IDE. Все работает нормально, если я запускаю тестовое приложение mosquitto_sub с моей Windows машины:
mosquitto_sub -h 192.168.1.8 -t sensor --cafile c:\projects\certs\ca.crt --cert c:\projects\certs\client.crt --key c:\projects\certs\client.key -p 8884 -d -u b -P b
Я получил исключение ниже, если я запускаю свою программу Java:

Я использовал те же сертификаты, что и с mosquitto_sub.exe.
Сертификаты были сгенерированы на сервере в соответствии с приведенной ниже процедурой:
openssl genrsa -des3 -out ca.key 2048
openssl req -new -x509 -days 3650 -key ca.key -out ca.crt -subj "/C=LT/ST=Some-State/O=KPV/CN=192.168.1.8"
openssl genrsa -out server.key 2048
openssl req -new -out server.csr -key server.key -subj "/C=LT/ST=Some-State/O=Internet Widgits Pty Ltd/CN=192.168.1.8"
openssl x509 -req -in server.csr -CA ca.crt -CAkey ca.key -CAcreateserial -out server.crt -days 720
openssl genrsa -out client.key 2048
openssl req -new -out client.csr -key client.key -subj "/C=LT/ST=Some-State/O=Internet Widgits Pty Ltd/CN=192.168.1.103"
openssl x509 -req -in client.csr -CA ca.crt -CAkey ca.key -CAcreateserial -out client.crt -days 720
Похоже, у меня проблема с именем CN в сертификате, но как это исправить и почему у меня нет проблем с souch в тестовое приложение mosquitto_sub.exe?
