I have had the same problem. I made a template to an agent that is very useful. Just insert your stuff into the template, update the Makefile and recompile ns(ok, you need some Otcl stuff too...:). The template cannot do anything useful by itself, but adding stuff into it results in magic... hehehe... cheers!

	SkelAgent();
	void recv(Packet*, Handler*);
