<P dir=ltr>Hi Ken,</P>
<P dir=ltr> </P>
<P dir=ltr>I changed ROS_IP to 127.0.0.1, but the problem is persisting. Are there any steps/procedures to ensure the proper network configuration for ROS besides those outlined in the wiki?</P>
<P dir=ltr> </P>
<P dir=ltr>Thanks!</P>

Hi Alexis,<BR><BR>For some reason 'localhost' isn't resolving on your machine. I would recommend trying using <BR><BR>ROS_IP=127.0.0.1<BR><BR>instead of ROS_HOSTNAME=localhost. NOTE: this will disable your ability to connect to remote machines with ROS.<BR><BR> - Ken<BR><BR><BR>
