I am setting up distributed testing in Linux machines with a master and a slave. Need your advice to overcome the below error message 

"Exception Creating a connection to 192.xx.xx. xx ;nested exception is java.net.NoRouteToHostException: no route to host ( Host Unreachable )"

I did the following steps

  1. Ensured Master and Slave has the same version of Jmeter
  2. Added the slave machine IP in Master's Jmeter.properites
  3. Created a keystore file in master and copied the generated rmi_keystore.jks to slave machine bin folder
  4. Run jmeter-server file in the slave machine ( There was an error hence added the slave machines ip in RMI_HOST_DEF=-Djava.rmi.server.hostname=192.xx.xx.xx)- success up and running
  5. Run the intended jmx file in master Run - Remote start - Slave machine
  6. Error Exception Creating a connection to 192.xx.xx.xx ; nested exception is java.net.NoRouteToHostException: no route to host (Host Unreachable )

I did check the connectivity between two machines when I ping i was able to reach each machine from one another,

Could be an issue with Firewall or port ? not sure

I have been banging my head , any pointers would be helpfull

thanks in advance

  • An OS networking error, can you ping those hosts on command line? – LMC Jul 25 '18 at 00:32
  • yes am able to ping master from slave & vice versa – Butner Jul 25 '18 at 08:16
  • Try to log the host IP from java code to make sure is correctly read from -D option. – LMC Jul 25 '18 at 12:22
  • Sorry, i coudnt get you, can you explain a bit more detail please – Butner Jul 25 '18 at 15:00
  • You are passing the host IP from command line as `RMI_HOST_DEF=-Djava.rmi.server.hostname=192.xx.xx.xx`, Try to log that value to check what it's really getting. – LMC Jul 25 '18 at 16:20

  1. check your Slave from Master

    example: nc -zvw3 192.168.1.31 1099

  2. if you get Ncat: No route to host then disable firewall on Salve and Master:

    • systemctl stop firewalld
    • systemctl disable firewalld
