I am using the same client connection properties for Producer and Consumer. But while I am able to Produce messages to RabbitMQ, getting following error for Consumer side. I have read many solutions all say check out connection properties, firewall etc. But I have working producer.
Consumer side connection codes:
String userName = "myuser"; // not guest
String password = "mypassword"; // not guest
String virtualHost = "/";
String hostName = "one_of_rbmq_ip";
Integer portNumber = 5672;
ConnectionFactory factory = new ConnectionFactory();
// "guest"/"guest" by default, limited to localhost connections
factory.setUsername(userName);
factory.setPassword(password);
factory.setVirtualHost(virtualHost);
factory.setHost(hostName);
factory.setPort(portNumber);
Connection conn = factory.newConnection();
Error gives at last line (conn)

I have changed my code like following it worked
Address[] addrArr = new Address[]{ new Address("10.28.94.117", 5672)
, new Address("10.28.94.118", 5672)
, new Address("10.28.94.119", 5672)
};
ConnectionFactory factory = new ConnectionFactory();
factory.setUsername("rabbitmq");
factory.setPassword("qa");
Connection connection = factory.newConnection(addrArr);
Channel channel = connection.createChannel();

A message is displayed indicating that the process of waiting for the key to be updated times out when JSCH is used for SSH connection
Here is my configuration:

config.put("StrictHostKeyChecking", "no");
//get the JSCH session
Session session = connectInfo.getJSch().getSession(serverConfig.getUsername(), serverConfig.getHost(), serverConfig.getPort());
session.setConfig(config);
//set password
session.setPassword(serverConfig.getPassword());

channel.setInputStream(null);
channel.setErrStream(System.err);
channel.connect();

I found the right answer！Error caused by my Linux server time inaccuracy,Synchronizing the exact time can solve this problem.

Why is the Ignite port listening not authenticated?
How can I set authentication?
Two parts:
It has to open the connection so that it can be told what the credentials are. If they're not valid, Ignite will disconnect
Ignite can only authenticate thin-clients out-of-the-box. I have not checked the code, but this could be a server or thick-client code path
I'm trying to connect to ActiveMQ Amazon broker via SSL. My application is written in C#.
Previously, I connected via TCP to localhost ActiveMQ broker, which worked:
using Apache.NMS;
using Apache.NMS.ActiveMQ;
using Apache.NMS.ActiveMQ.Commands;
void Connect()
{
String brokerUri = "activemq:tcp://" + host + ":" + port + "? transport.useLogging=true&wireFormat.maxInactivityDuration=0&userName=myUsername&password=myPassword";
NMSConnectionFactory factory = new NMSConnectionFactory(brokerUri);
IConnection connection = factory.CreateConnection();
connection.Start();
}
To connect to ActiveMQ Amazon broker via SSL, I have modified the code in the following way:
void Connect()
{
String brokerUri = "ssl://" + host + ":" + port + "? transport.useLogging=true&wireFormat.maxInactivityDuration=0&userName=myUsername&password=myPassword";
SslTransportFactory transportFactory = new SslTransportFactory();
Uri uri = new Uri(brokerUri);
ITransport transport = transportFactory.CreateTransport(uri);
transport.Command = Command;
transport.Exception = Exception;
transport.Start();
ConnectionFactory factory = new ConnectionFactory(brokerUri);
IConnection connection = factory.CreateConnection();
Connection con = (Connection)connection;
con.ITransport = transport;
con.Start(); => Here the exception is thrown: User name [null] or password is invalid.
}
private void Exception(ITransport sender, Exception command)
{
}
private void Command(ITransport sender, Command command)
{
}
However, upon starting the connection, User name [null] or password is invalid. Exception is thrown.
Please advise.
You're currently passing user credentials via the URI. However, I don't see any reference to username or password in the URI reference documentation. Also, the fact that the exception indicates the user name is null indicates the user credentials in your URI are simply being ignored.
Instead you should pass the user credentials in the CreateConnection method as documented here, e.g.:
IConnection connection = factory.CreateConnection("myUsername", "myPassword");
I have installed "erlang" and "rabbitmq" in my windows 7 machine. But when I am trying to run this code I am getting One exception.
package com.rabbitmq;
import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.ConnectionFactory;
public class SendMessage {
private final static String QUEUE_NAME = "hello";
public static void main(String[] argv) throws Exception {
ConnectionFactory factory = new ConnectionFactory();
factory.setHost("localhost");
Connection connection = factory.newConnection();
Channel channel = connection.createChannel();
channel.queueDeclare(QUEUE_NAME, false, false, false, null);
String message = "Hello World!";
channel.basicPublish("", QUEUE_NAME, null, message.getBytes("UTF-8"));
System.out.println(" [x] Sent '" + message + "'");
channel.close();
connection.close();
}
}
I am getting this Exception.

see the broker logfile.

When I am trying to list the users I am not getting any existing user and add_user is also not working in cmd link
In your ConnectionFactory you need to set your username and password, if your have created any or you can use the default user "guest" with password "guest", which can be accessible only from localhost.
you can create new user (userA) and password (userA123).
And set
factory.setHost("your_pc_ip");
factory.setUsername("userA");
factory.setPassword("userA123");
in sender and receiver classes.
I am trying to connect to a remote external server using TCP sockets in WCF code
My WCF service is the client which has code using sockets to connect to an external server.
This code sends a request to an external server and receives the server response
int byteCount = 0;
Socket m_socClient;
try
{
string query = "My Request String";
m_socClient = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
System.Net.IPAddress remoteIPAddress = System.Net.IPAddress.Parse("127:0:0:0");
System.Net.IPEndPoint remoteEndPoint = new System.Net.IPEndPoint(remoteIPAddress, 1234);
EVCommon.Log("COnnecting to" + IPSelected + Port);
m_socClient.Connect(remoteEndPoint);
try
{
if (m_socClient.Connected)
{
EVCommon.Log("Connected to" + IPSelected + Port);
var reQuestToSend = string.Format("POST /ZZZZZ HTTP/1.1\r\nContent-Length:{0}\r\n\r\n{1}", query.Length, query);
byte[] bytesToSend = Encoding.ASCII.GetBytes(reQuestToSend);
byteCount = m_socClient.Send(bytesToSend, SocketFlags.None);
byte[] bytesReceived = new byte[1024];
byteCount = m_socClient.Receive(bytesReceived, SocketFlags.None);
Response271 = Encoding.ASCII.GetString(bytesReceived);
m_socClient.Disconnect(false);
m_socClient.Close(5000);
}
}
catch(Exception ex)
{
EVCommon.Log(ex.Message);
}
}
If I make a windows application with the same client code to connect to the remote server, it is successful. I am able to connect, send and receive
This error occurs only when I bring WCF into the picture. The code fails at if(m_socket.Connected). So it is not able to connect successfully.
A request to send or receive data was disallowed because the socket
is not connected and (when sending on a datagram socket using a sendto call) no address was supplied.
Thank you
The difference is that the windows applications runs in the identity of the logged in user and the WCF service runs in the identity of the application pool.
What is probably happening is that the application pool is running as NETWORK SERVICE which does not have the right to open a port.
Try changing the identity of the app pool to your user to check if this is the problem.
