Greetings! I observed strange qpidd behavior. It is started from systemd with following command line:
/usr/sbin/qpidd --config /etc/qpid/qpidd.conf qpidd.conf contains following options: pid-dir=/var/run mgmt-enable=yes require-encryption=yes ssl-cert-db=/etc/qpid/certs ssl-cert-name=qpid.logit-ag.de ssl-port=5671 auth=no Daemon listens on both ports (5671 and 5672) but when I try to access it using eg. qpid-tool -q I'm getting the expected results: qpid-stat -b amqps://localhost:5671 -q -- works qpid-stat -b amqp://localhost:5672 -q -- fails (as expected) with 'encryption required' error. One of my colleagues claimed that he was able to send a message successfully to this broker using *unencrypted* connection to port 5672. I captured the traffic to this broker and to my surprise I have seen a message in plain text, which was successfully delivered to receiver. He used this package to send the message: https://mvnrepository.com/artifact/org.apache.qpid/qpid-jms-client/2.0.0 Now what do I miss in my qpidd configuration? qpidd version used is 1.39.0 Best regards, -- Michael Ivanov
