ActiveMQ vs AMQP .NET Lite versions - activemq

ActiveMQ, as per line 151 in AmqpWireFormat, refuses connections with a AMQP protocol version other than 1.0.0.
AMQP .NET Lite, as per line 411 in Connection, sends 0.1.0.0. At the same time it claims to do Full control of AMQP 1.0 protocol behavior.
Obviously ActiveMQ refuses connections from AMQP .NET Lite with "Connection attempt from non AMQP v1.0 client. AMQP,0,1,0,0".
The client does:
Address address = new Address("amqp://localhost:5672");
Connection connection = new Connection(address);
Session session = new Session(connection);
And ActiveMQ logs:
2017-03-28 09:11:28,403 | DEBUG | Transport Connection to: tcp://0:0:0:0:0:0:0:1:54352 failed: org.apache.activemq.transport.amqp.AmqpProtocolException: Connection from client using unsupported AMQP attempted | org.apache.activemq.broker.TransportConnection.Transport | ActiveMQ Transport: tcp:///0:0:0:0:0:0:0:1:54352#5672

On the command line it says:
WARN | Connection attempt from non AMQP v1.0 client. AMQP,0,1,0,0
ActiveMQ then aborts the connection.
The ActiveMQ configuration includes:
<transportConnectors>
<transportConnector name="amqp" uri="amqp://0.0.0.0:5672" />
</transportConnectors>
This all looks to me like ActiveMQ expects version 1.0.0.0 and amqpnetlite sends 0.1.0.0.
Where to, from here?

By default ActiveMQ requires authentication. try
string queueName = "q1";
Connection connection = new Connection(new Address("amqp://user:pwd#localhost:5672"));
Session session = new Session(connection);
SenderLink sender = new SenderLink(session, "sender", queueName);
Message message = new Message("Hello World");
sender.Send(message);
connection.Close();
The user name and password should be in users.properties config file. Also it is recommended to use async API to avoid blocking I/O calls.

Both ActiveMQ and AMQP .NET Lite support the ISO/IEC Standard 1.0 version of AMQP. The protocol header "AMQP0100" indicates version 1.0 of the protocol. AMQP .NET Lite is known to work with ActiveMQ so I suspect you have some other configuration issue.

My assumption is that you haven't turned off the broker's enforcement of requiring the client to connect via a SASL handshake either via SASL anonymous or SASL plain depending on whether you've configured a real authentication plugin or not. I would bet that if you configured the broker by adding the options wireFormat.allowNonSaslConnections=true that it would probably work.
From the information you've provided the .NET client is not using SASL so the broker is rejecting it. The SASL header would be "AMQP3100"

RabbitMQ SSL Connection with Apring AMQP 1.4.3

I am trying to connect to RabbitMQ over SSL. I have followed the RabbitMQ SSL documentation linked [here}(https://www.rabbitmq.com/ssl.html).
As per RabbitMQ SSL documentation connecting using SSLv3 and TLSv1 is not recommeded due to known vulnerabilities. Due to this I have disabled these protocols on RabbitMQ as per instructions.
I am using Spring AMQP 1.4.3 to connect to RabbitMQ.
ApplicationContext context = new GenericXmlApplicationContext("classpath:/testConfig/testrabbit-context.xml");
RabbitTemplate template = context.getBean(RabbitTemplate.class);
MessageProperties messageProperties = new MessageProperties();
org.springframework.amqp.core.Message amqpMessage = new org.springframework.amqp.core.Message("Test".getBytes(), messageProperties);
String routingKey = "TEST.businessevent.route";
template.send(routingKey, amqpMessage);
My config:
<rabbit:connection-factory id="rabbitConnectionFactory"
connection-factory="clientConnectionFactory"
host="localhost"
port="5671"
username="username"
password="password"
virtual-host="test_host" />
<rabbit:admin connection-factory="rabbitConnectionFactory" />
<rabbit:template id="rabbitTemplate"
connection-factory="rabbitConnectionFactory" exchange="test_topic" />
<rabbit:topic-exchange name="test_topic" durable="true" />
<bean id="clientConnectionFactory" class="org.springframework.amqp.rabbit.connection.RabbitConnectionFactoryBean">
<property name="useSSL" value="true" />
<property name="sslPropertiesLocation" value="/testconfig/rabbitSSL.properties"/>
</bean>
rabbitSSL.properties:
keyStore=file:/client/keycert.p12
trustStore=file:/lib/security/rabbitStore
keyStore.passPhrase=testpassword
trustStore.passPhrase=testpassword
However when I use the above code and config to connect to RabbitMQ over SSL I am getting a fatal alert: protocol_version.
When I looked at the org.springframework.amqp.rabbit.connection.RabbitConnectionFactoryBean class that Spring is using to connect to RabbitMQ, I can see that the protocol appears to be hard coded to SSLv3.
SSLContext context = SSLContext.getInstance("SSLv3");
context.init(kmf.getKeyManagers(), tmf.getTrustManagers(), null);
this.connectionFactory.useSslProtocol(context);
This code works fine if I do not disable SSLv3 on RabbitMQ. However I need to connect to RabbitMQ using Tlsv1.2. Can I do that using Spring AMQP 1.4.3 or do I need to use another version.
Thanks for any help you can provide me with this issue.
While searching for RabbitMQ remote access I came across the below Spring application.properties configuration settings that can be done in Spring to configure the RabbitMQ connections.
https://www.oodlestechnologies.com/blogs/Connect-to-SSL-enabled-RabbitMQ-server-Springboot/
spring.rabbitmq.host=hostURL
spring.rabbitmq.port = hostPort
spring.rabbitmq.username = username
spring.rabbitmq.password = password
spring.rabbitmq.virtual-host=virtualHost
spring.rabbitmq.ssl.enabled=true
spring.rabbitmq.ssl.algorithm=TLSv1.2
https://www.baeldung.com/spring-remoting-amqp#2-configuration
I have opened a JIRA Issue for this.
In the meantime, the RabbitConnectionFactoryBean is just a convenience class to make configuring an underlying connection factory more "Spring friendly" with defaults.
Instead, you can perform this initialization in your own code (perhaps using a #Bean declaration using Java Configuration).
Okay, I was trying to connect by Spring Boot application(2.1.4.RELEASE) that uses spring-boot-starter-amqp (2.1.4.RELEASE) to an AWS Managed instance of RabbitMQ aka Amazon MQ and it would fail with a similar error. What worked for me was setting these properties.
spring.rabbitmq.ssl.enabled=true
spring.rabbitmq.ssl.algorithm=TLSv1.3
Setting these properties explicitly was not required in an application that was using Spring Boot and spring-boot-starter-amqp (2.7.8) and they worked out of the box. Here's a mention of the same in Spring AMQP Documentation.

Apache http core nio 4.3.3 reverse proxy SSL error

I am developing a reverse proxy using http core nio 4.3.3 and need to connect to a Secure/HTTPS endpoint via the proxy. I took the reverse proxy(Asynchronous HTTP reverse proxy)[1] and added SSL support as shown below.
SSLContext clientSSLContext =
SSLUtil.createClientSSLContext(TRUST_STORE_LOCATION,
TRUST_STORE_PASSWORD);
final IOEventDispatch connectingEventDispatch =
new DefaultHttpClientIODispatch(
clientHandler,
clientSSLContext,
ConnectionConfig.DEFAULT);
...
connectingIOReactor.execute(connectingEventDispatch);
When I send the request, I am getting this error,
java.io.IOException: SSL not supported
The Stack trace is given below.

I enabled SSL debug logs as well, but still could not figure out the issue.
Then I debugged this and found out that the proxy received the request from the client and drops due to an exception inside the handle method of HttpAsyncRequestConsumer. The exception is java.io.IOException: SSL not supported
Also note that the SSLContext was working fine with a reverse proxy written using the netty transport.
Any help would be appreciated.

Regards,

When using a connection pool on the client side to manage outgoing connections one needs to ensure that the connection factory used by the pool to create new connection objects is SSL capable. Please make sure that the connection pool is properly configured.
Thanks a lot for the advice. That solved the issue.
clientSSLContext =
SSLUtil.createClientSSLContext(TRUST_STORE_LOCATION,
TRUST_STORE_PASSWORD);
BasicNIOConnFactory connectionFactory =
new BasicNIOConnFactory(
clientSSLContext,
null,
ConnectionConfig.DEFAULT);
proxyConnPool = new ProxyConnPool(connectingIOReactor, connectionFactory, 5000)

ActiveMQ Amqp C# ConnectionFactory and IConnectionFactory

I am using Amqp with ActiveMQ, which requires version 1-0-, not the old version 0-9-
In the version 0-9-* with "RabbitMQ.Client" (I was using RabbitMQ and switching to ActiveMQ), the following C# code works to connect to one broker.
factory = new ConnectionFactory()
{
Protocol = Protocols.FromEnvironment(),
HostName = IpAddress,
Port = Port,
VirtualHost = VirtualHost,
UserName = User,
Password = Password
};
but with version 1-0-* in "Apache.NMS.ActiveMQ", this does not work,
(the example here use IConnectionFactory instead: http://activemq.apache.org/nms/examples.html
but could not input HostName, Port, VirtualHost, UserName, Password there. )
How can I use "Apache.NMS.ActiveMQ", and do the connection with username, password in the code.
Thanks :)
ActiveMQ is a multi protocol broker. AMQP 1.0 is one of the wire protocols it supports.
However, the Apache.NMS.ActiveMQ lib is using the OpenWire protocol (default port 61616 on AMQ). It's straight forward to connect using NMS to OpenWire, even with username and password.
IConnectionFactory factory = new ConnectionFactory("tcp://localhost:61616);
using (IConnection connection = factory.CreateConnection("user1234","s3cr3tp4ssw0rd")
{
using (ISession session = connection.CreateSession ())
{
// send a message or whatever
If you really want to connect using AMQP, I suggest the QPid proton lib instead of NMS. NMS has something going on as well, but it's not there yet.
There is now an Apache ActiveMQ released version of Apache.NMS.AMQP its available it Nuget.
https://www.nuget.org/packages/Apache.NMS.AMQP

Repeated log : Warn Transport Connection to tcp:<ip> failed: java.net.SocketException: Connection reset

I am running ActiveMQ 5.9.0 release on my local machine for dev purposes (Windows 7). I am using AMQP as the protocol and Apache qpid as the client to consume messages (publish subscribe) from activeMQ broker (AMQP 1.0 protocol).
Although I have commented out all the protocols except amqp in activemq.xml, still periodically I am seeing the below message in broker log (standard out):
WARN: Transport Connect to tcp://<ip> failed: java.net.SocketException: Connection reset
I did try to "uncomment" the openwire protocl definition in activemq.xml and append transport.useInactivityMonitor=false (based on googling around):
I still cannot get warning messages to disappear.
I haven't used it myself. But the amqp protocol is using the tcp transport under the covers. Use of the protocol is documented here. You can configure it to use nio as well. It is hardcoded to have useInactivityMonitor=false. You can modify the transport options on the amqp transport by setting those options in the connect uri. For example:
<transportConnectors>
<transportConnector name="amqp" uri="amqp://0.0.0.0:5672?transport.keepAlive=true"/>
</transportConnectors>
The tcp transport options are documented here.
