    Kindly suggest.

    no it is expect to have 2 way communication for the product to work.

    You will not be able to configure the probe and robot settings out of the box that way.

    If you setup a passive robot you can do this.

    Hi Gene,

     

    Robot is not setup as  a passive. In addition, I tried the steps you mentioned above but the robot is already showing in the robot list. Even in the controller.log, i can see that robot is able to establish connection with Hub.

     

    Problem is this that from hub we are unable to telnet to this linux box on port 48000

     

    We have checked and found that tracert is fine and there is no firewall or blockage between the hub and robot.

     

    Any more suggestion please?

     

    Regards,

    Hi Imran,

     

    There are more chance of local firewall [iptables] is enabled on the Linux robot and blocking the same. So if possible you can disabled the local firewall or allow your Nimsoft network on the Linux robot to communicate with hub.

    You need to take help from SA to disable or verify, as its required root permission.

    To check iptables you can use command:  iptables -L
