    Hello Sir,

    I have followed the same instructions as on the article for ssh connectivity to VM1 to VM2 and VM1 to VM3.
    Also the permissions are 700 for .ssh directory on both the VMs as well as on the VM1.

    Thanks

      @Raman,

      If you’ve followed instructions correctly, then it should work without any issues, please cross check again…If you still unable to connect, try to re-upload pub key to VM3 and see..

    Hello,

    I wanted to run the script through ssh on two VMs, via another VM.
    When i configure ssh passwordless on VM1 to run the script on VM2 it works fine , but when i configure VM1 to run the scriptn on VM3, it overrides hence fails and prompts for the password.

    Goal is to access two or more than two VM2 and VM3 through VM1.
    Individually it works fine but while configuring the both VM2 and VM3 it only runs the script on the latest VM configured.

    Thanks
    Raman

      @Raman,

      Have you followed the same instructions for VM1 to VM2 and VM1 to VM3? could you check the .ssh/authorized_keys file permission on both VM’s? it should be 700 permission on .ssh directory.
