I am developing a application in C++ using Qpid C++ Messaging API. The application should send messages to another .net application running amqpnetlite.
However, when initiating the connection, on the C++ side, I got this security error:
[Security] error Expected SASL frame; got type \0x00
[Security] error Unexpected descriptor in SASL negotiation: unknown-descriptor (0x10).
I was wondering anyone has any thoughts about the error?
Additional Info:
- I confirm that the C++ application speaks AMQP 1.0.
- I also have this python script (using Qpid Proton 0.10) that speaks AMQP 1.0 and sends essentially the same message to the .net application. This python script works just fine.
- I set up a C++ AMQP broker with
qpidd --auth no. Now both the python script and the C++ application (connection configured with{sasl_mechanism:ANONYMOUS}) could send messages through.
Any or all help would be appreciated!
EDIT
Find the solution myself.
When initiate the connection on the C++ application side, the SASL_MECHANISMS must be set to NONE explicitly, as amqpnetlite defaults to disable any authentication (not even the ANONYMOUS mode) when listening for incoming connection.
This can be done in the C++ code by doing
connection.setOption("sasl_mechanisms","NONE");
or by supplying the option from the command line.
./send.o localhost {protocol:amqp1.0\,sasl_mechanisms:NONE}
The NONE option for sasl_mechanisms is documented nowhere in the Qpid C++ API documentation. It has to be found out by looking into the source code.
