Jmeter Distributed testing - unable to connect the remote (slave systems)
I am getting the below error
"non-JRMP server at remote endpoint"
It looks like an incorrect setup of RMI ports, JMeter master tries to connect to the slave machine using the hostname or IP address and port which is specified in the remote_hosts property or passed via -R command line argument.
The error means that something else, not JMeter's RMI registry is running on machine 192.168.0.103 on port 1099.
So you need to connect to your slave machine and check what's listening on port 1099 using netstat or equivalent and either terminate that application or amend JMeter configuration to use different port.

I try to run a distributed test using JMeter, I have 2 EC2 instances
Master Public IP: 54.xxx.xx.xx
Slave Public IP: 204.xxx.xxx.xxx
I have opened all the necessary ports that were used in the configuration.
I can ping each EC2 from the other one and the ping is successful.
But when I try to start the test, the server failed and return [No route to host (Host unreachable)].
My plan is to use more than 1 slave.
Error Return From Master Server
As per NoRouteToHostException exception description:
Signals that an error occurred while attempting to connect a socket to a remote address and port. Typically, the remote host cannot be reached because of an intervening firewall, or if an intermediate router is down.
So make sure that the RMI ports which JMeter slave is listening are:
Not dynamic
Open in your operating system firewall
Open in EC2 Security Groups

In centos environment I setup a rmi_keystore.jks in master device and copy it to the bin of Jmeter worker machine too.
In my master device's jmeter.properties file I only did below changes.
remote_hosts=10.54.225.200
server.rmi.localport=4000
However, In worker device, when I try to start the server.
by giving master's hostname is 10.54.225.190
cd apache-jmeter-5.4.1/bin
./jmeter-server -Djava.rmi.server.hostname=10.54.225.190
below error occurs. The port 4000 is not in used though.
If you need to use different SERVER_PORT instead of default 1099 I believe you need to amend your setup to something like:
Slave: jmeter-server -Jserver_port=4000
Master: jmeter -R 10.54.225.200:4000 -n -t test.jmx
See Using a different port user manual entry for more details if needed.

I'm Trying to setup Master Slave setup of Jmeter in Cloud.
Things I have done the setup in CLOUD for Master and Slave
I have created rmi.keystore.jks file in Master and copied the same to Slave machine.
I have installed the same versions of Java and Jmeter in both the Machines
I have added IP address of Slave machine in jmeter.properties file of Master
Please help me why I'm facing connection timed out error when trying to execute jmeter script in Cloud machine. Receiving:
Connection refused to host: 10.XXX.XX.XXX; nested exception is: java.net.ConnectException: Connection timed out: connect
If this is really in CLOUD then:
My expectation is that you need to use external IP addresses as I can only see Class B network-type address which most probably cannot be connected from the outer world
You need to ensure that the following ports are open in the CLOUD (whatever you mean by this term) and in operating system firewalls/security groups:
1099 (or whatever port you define as the server_port)
the port you define as the server.rmi.localport
the port(s) you define as the client.rmi.localport

Why am I getting the following error in PerfMon jmeter plugin?
"ERROR: java.io.IOException: Agent is unreachable via TCP"
how to configure perfmon plugin in Jmeter 4.0 version
Make sure to install Server Agent to the server you want to monitor and launch it
Make sure that default port of 4444 is open for TCP and UDP traffic in your operating system firewall.
In order to test connectivity you can send test message to the Server Agent using Telnet client software (you can use Putty if you don't have any Telnet client installed). If everything is fine you should see Yep response. JMeter should be able to connect to the Server Agent and collect the metrics of your choice:

I am trying do distributed testing on linux server using apache-jmeter 2.9
The default port (1099) is already used(by jboss)
I changed the port as 1097
I start jmeter-server on one machine for now and start test on single machine.
jmeter-server seems to start succesfuly
but when evern i trying to exceute script is shows following error.
[jboss#StagingSvr2 bin]$ ./jmeter -n -t CBL_Load/CBL_Admin_Load.jmx -l
.jtl -R 172.16.0.2

I have gone through google but not able to find exact solution that where I am doing blundder!
Make sure nothing is listening at the port 1097 using netstat or nc or telnet. Looking into non-JRMP server at remote endpoint something is present there which is not JMeter RMI endpoint. Try locating a free port using aforementioned tools and bind JMeter slave to it
With regards to bind JMeter slave I would recommend amending your startup command to something like:
./jmeter-server -Dserver_port=xxxx
where xxxx is a free port on your Linux system
Amend your Master startup command to include the port as well like:
./jmeter -R 172.16.0.2:xxxx -n -t CBL_Load/CBL_Admin_Load.jmx -l result.jtl
