2011-06-23 04:52:09 -0500	answered a question	ROS cannot communicate over network under Natty Alright... it was a rather pathetic network problem. Actually I don't know why, but after the update to Natty, my `/etc/hosts` file didn't contain the IP adress from my local network anymore. The following entry fixed this. `192.168.1.XXX hostname`
2011-06-23 03:23:03 -0500	asked a question	ROS cannot communicate over network under Natty After updating to Natty, ROS can't communicate locally via network ports no more. `Unable to contact my own server at [http://hostname:48064/].` Changing/setting the variables `ROS_MASTER_URI`, `ROS_HOSTNAME` and `ROS_IP` according to this question didn't help. The tests according to the ROS network troubleshooting guide were partially successful. `ping` works for `127.0.0.1`, for `localhost` and for the hostname. `netcat` works for `127.0.0.1` and for `localhost`, but not for the hostname. Sorry, in case this is a rather pathetic network problem. Maybe it's something specific to Natty?
