Keisuke,
Are you sure that your network is configured correctly for ROS? Can
your Linux machine ping "ihcikuy". If not, you may need to set ROS_IP
on the Windows machine.

hope this helps,

>
> ----------------------
>
> My environment is as follows.
>
> ------
>
> 1. Windows side
>
> Windows XP Professional SP3
>
> Copied compiled roslib, rospy, std_msgs, talker.py, and listener.py. (All
> are compiled in Linux OS with the version cturtle)
>
> The line "roslib.load_manifest("package_name")" of talker.py and listener.py
> is commented out.
> (
> The code is base on

> )
>
> ROS_MASTER_URI=http://192.168.0.6:11311
>
> ROS_ROOT is correctly modified.
>
> PYTHONPATH for roslib, rospy and std_msgs is correctly set.
>
> python2.6 and Pyyaml for python2.6 installed.
>
> ------
>
> 2. Linux side
>
> Ubuntu 10.04
>
> #uname -a
> Linux ubuntu 2.6.32-24-generic #39-Ubuntu SMP Wed Jul 28 06:07:29 UTC 2010
> i686 GNU/Linux
> Installed ROS cturtle
>
> IP : 192.168.0.6
> hostname : ubuntu
>
> ROS_MASTER_URI=http://localhost:11311
>
> # python --version
> Python 2.6.5
>
> ------
>
> When I run roscore on the Linux side and both listener/talker on the Windows
> side, the messages between two nodes are correctly sent.
> I could see the messages for both terminals in Windows OS.
>
> On the linux side
> # rostopic list
> /chatter
> /rosout
> /rosout_agg
>
> so I tried to see
> # rostopic echo /chatter
> but I couldn't see anything even when I could see messages on the two
> terminals in the Windows side.
>
> When I run
> # rxgraph
> I saw strange nodes.
> Nomally all nodes contains just one black circle,
> but the nodes created on Windows OS contain double red circles.
> When I clicked the talker node, I got following error.
>
> ERROR: Communication with node[http://ihcikuy:1586/] failed!
>
> The lister node on rxgraph has different name like "listener_1104_128...."
> and also surrounded by double red circles.
> When I clicked the lister node, I got
>
> ERROR: Communication with node[http://ihcikuy:1586/] failed!
>
> Since ROS_MASTER_URI on the Windows machine was set to be "192.168.0.6", it
> cannot be "ihcikuy".
>
> ------
>
> Does anybody has same kind of experience?
> What's the problem?
>
> ----------------
>
> Also, I tried to run lister.py on Linux and talker.py on Windows,
> but I couldn't get any results.
>
> Did I make mistakes following the tutorial?
>
> Any information are welcome.
>
> Thanks in advance,
