[ros-users] [Discourse.ros.org] [General] Rosservice_echo.py a wannabe tool to imitate rostopic echo with services

[Sam Pfeiffer]

Hey everyone,

Trying to make the best use of my jetlag I was playing around and made:

[rosservice_echo](https://github.com/uts-magic-lab/rosservice_echo)

As the README says:

> Just like rostopic echo /your_topic but with services.
> 
> Well, similarly.
> 
> You need to run it as root from a machine that is either doing the service calls or exposing the server. That's because it internally uses scapy to sniff network packets.

It looks something like:

    rosrun rosservice_echo rosservice_echo.py /rosout/get_loggers
    [roscpp/GetLoggersRequest]:

    [roscpp/GetLoggersResponse]:
    loggers: 
      - 
        name: ros
        level: info
      - 
        name: ros.roscpp
        level: info
      - 
        name: ros.roscpp.roscpp_internal
        level: info
      - 
        name: ros.roscpp.superdebug
        level: warn
    ---

Maybe someone else is interested. It may be a baby step in order to have rosservice bag tool someday. Or just a fun toy project to discover [scapy](http://www.secdev.org/projects/scapy/).
