Hi Tommy,

There are some examples in the linux_networking stack. They are still

C++
https://code.ros.org/svn/ros-pkg/stacks/linux_networking/trunk/wpa_supplicant_node/src/nodes/wpa_supplicant_node.cpp

Python
https://code.ros.org/svn/ros-pkg/stacks/linux_networking/branches/linux_networking_pnetworks/network_monitor_udp/nodes/udpmonsourcenode.py
