At first time i deployed all hono services via minikube and helm chart on my local pc and i was able to use any services. But when i deploy hono services on remote server, i couldnt start Hono Command Line Client as a consumer from my local pc to remote server. i got this message;
09:22:42.438 [vert.x-eventloop-thread-0] WARN o.e.h.c.impl.ConnectionFactoryImpl - can't open connection to container [null] at [amqp://10.0.1.68:15671, role: unknown]: underlying connection was disconnected while opening AMQP connection

unlike the eclipse-hono-dispatch-router-ext services, i can use other services like device registry and mqtt client adapter.Also i tried to run
java -jar hono-cli-*-exec.jar --hono.client.host=$AMQP_NETWORK_IP --hono.client.port=15672 --hono.client.username=consumer#HONO --hono.client.password=verysecret --spring.profiles.active=receiver --tenant.id=$MY_TENANT
this command line on remote server via ssh connection, i got same result.
Can anyone help me? if asked additional information, i will send it.

I have an elastic apm server version 7.17.1. There are only to Django application on the server. The APM service is using about 140MB of memory. When connecting new agents, I receive a timeout error.

If I use flask or Django or PHP, new apps are registered.
(I couldn't find logs from Go, but that APM agent failed as well.)
APM server logs did not appear relevant as the errors occurred in both instances
Check your IPS. In our env, we saw the IPS swatting down packets from Java and Go-based apps. I'm no developer, but once we got those sources white-listed, we saw the Agents information coming through :)
Here is the scenario:
My kafka server and the zookeeper are running and working fine on the remote server as long as I launch the process on the same remote server.
I don't have any connectivity issues between my local machine and the server. I can ssh and access all other applications on my remote server from my local machine.
When trying to connect a client to the remote zookeeper directly from my local machine I get a connection timeout. Debugging shows that a NoRouteToHost exception is being thrown.
The client logfile contains the following lines:
org.apache.zookeeper.ZooKeeper: Initiating client connection, connectString=remotehost:2181 sessionTimeout=120000
watcher=org.I0Itec.zkclient.ZkClient#62807a4d
org.apache.zookeeper.ClientCnxn: Opening socket connection to server
remotehost/192.13.12.1:2181. Will not attempt to authenticate using
SASL (unknown error)
Note the "remotehost/192.13.12.1:2181". The URL I'm specifying is remotehost:2181. He appears to resolve the hostname to IP correctly and then... slapping a forward slash and the IP on to the URL which looks weird to me. Is this how he should resolve and pass down the URL to the socket?? Or is this the cause of my problem.
Found the issue. The zookeeper listen port was not open to the firewall.
Unable to communicate with server - I/O error on GET request for "https://api.ng.bluemix.net/info":Connect to 10.81.82.132:80 [/10.81.82.132] failed: Connection timed out: connect; nested exception is org.apache.http.conn.HttpHostConnectException: Connect to 10.81.82.132:80 [/10.81.82.132] failed: Connection timed out: connect
I am getting this error when trying to create a Bluemix server in Eclipse, specifically on click of Validate Account button. I have downloaded and installed the IBM Bluemix for Eclipse plug-in but still having connectivity issues. Any help is appreciated.
The connection error is depending from the wrong IP address your internet ISP/provider is returning for api.ng.bluemix.net
Check your DNS configuration, you could run the following command
nslookup api.ng.bluemix.net
to check which DNS server is returning the wrong IP address.
Steps followed to installed Load Agent on AWS.
Firewall Exception from controller for port 50500 , 54345, 443 and 3389 on load agent machine.
Installed Load Runner Setup [ as Load agent Process is also a part of Load Runner Setup]
Allowed all the programs [Agent Process, Agent Service.. etc] from Windows Firewall.
Tried to connect from Load Controller. Error received on controller is
Communication error: The Client failed to send packet. The socket has been shut down.
As per OPs team, the agent is trying to establish a connection back to a server 54.xxx.xx.xxx[Unknown AWS IP] on port 10051 and failing eventually where as this particular server is unknown to us.
Version of Loadrunner on Agent and Controller is same.
Please tell how do i have to install or configure MI LISTENER or AGENT PROCESS over firewall.
Turns out, it was a firewall exception mess made by the IT department. The above mentioned steps will clearly allow a communication with the LR Controller and Agent.
I have WAS MQ 7.1 Server installed in windows. My application running on unix is trying to connect to this server during which it gives the error "MQ Connect failed 2195" in the application logs. On debugging the code , i found it is while connecting to the q manager that it is throwing this error.
I tried to run a netstat on the MQ Server port no. and do a telnet to check if there is any connection being established . But I could not see any connection being established to the q manager .
The possible issues could be
1. Que Manager has not been started
2. Listener not started
3. Initiation queue not started or created or attached(usually optional depending on set up)
4. Listening to the wrong Port or IP
5. Firewall stopping traffic to Port or IP
6. Queue Manager not created on destination
7. Not authorized to Queue manager and/or channel and/or queue
8. Trial MQ copy expired.
9. Wrong Queue manager name
10. Wrong channel name or password or queue or queue type
Have done the following to check if it is working fine .
1. Tried to put a message from windows to the MQ Server which was successful.
2. Gave auth(setmqaut) permission to Request queue that was created.
3. There is no firewall between application and MQ Server.
4. Channel name , q manager , IP and port no.s are correct.
In my windows MQ Setup i have created the Server connection channel and Client connection Channel.
export the mqm lib to SHLIB_PATH.
Added the application user to mqm group and also the windows user through which I had created the MQ Server setup
Had copied the AMQCLCHL.TAB to the unix machine containing the client program.
exported MQCHLTAB to the table filename
exported MQCHLLIB to the path containing the table name
exported the MQSERVER=QMgrName/CHANNEL1/hostname from the client machine.
Please let me know if I am missing anything w.r.t connection of the application(in Unix) to the MQ Server(in Windows).
2195 is MQRC_UNEXPECTED_ERROR. It implies something that should not have happened, even if you set it up wrong. It may well be accompanied with an FDC file in the errors directory. You should raise a PMR with IBM Service.
