2013-07-19 11:52:47 -0500 | asked a question | ros not communicating over sub-network Hello, I have a PC running Ubuntu 12.04 with three subnets with two physical adapters: eth0 is a private subnet. wlan0 is an Internet-connected subnet. I have ros Groovy on this PC which is acting as the server. It runs "roscore" which reports: I have a device connected over eth0 with the IP 192.168.11.3. I have run on this device: I can publish a message from this device (192.168.11.3) to the PC (192.168.11.2). But I cannot publish any message from the PC (192.168.11.2) to the device (192.168.11.3). It seems that ros on the PC doesn't use the 192.168.11.x subnet and it uses only the 192.168.10.x. Last important point, in the Ubuntu connection settings for eth0 (192.168.11.x), I have checked the box "Use this connection for resources on this network". Any idea what I could do to fix this problem? Many thanks in advance. |
