household_objects_database remote access issue
I am trying to access household_objects_database remotely following the tutorial here
I launched the remote connection script
roslaunch household_objects_database objects_database_remote_client.launch
However when I try to run the following command
rosservice call /objects_database_node/get_model_list REDUCED_MODEL_SET
I get the error: Unable to communicate with service [/objects_database_node/get_model_list], address [rosrpc://grasp.willowgarage.com:15432]
It says in the tutorial that server might be down. However website (grasp.willowgarage.com) seems to be up. I try to ping to port 15432 and here is the result
nmap -p 15432 grasp.willowgarage.com
Starting Nmap 5.21 ( http://nmap.org ) at 2012-11-02 13:02 EET

So, what am I doing wrong? Is this
