Hi there,
I'm trying to drop packets under some conditions I want. What I've done is,
change the recv function's code in connector.cc so that when the conditions
I set are met, I use drop(p) to drop the packet.
The problem is that those packets vanish from the logs, which is obviously
something
To provide some more info:
Suppose I have the following topology:

What I want is node D to drop packets from some specific nodes. What I've
done is the following:
I added one variables in the node.cc && node.h to define if the packets from
th
first of all you should determine which layer is responsible for dropping
the packet?
I suppose it's routing agent, for example. then, put this line wherever you
want to drop the packet p:
drop(p, DROP_RTR_YOUR_REASON);
put this at line 97 in file %NS_DIRECTORY%/trace/cmu-trace.h
#define DROP_RTR
Thanks for your responce,
in my case I have a wired scenario and I use the default (static) routing.
As I say in the previous post, I do all the work in the connector class. I
don't really care from which layer the packet is dropped, as long as I have
access to the packet to read the information
After a closer look I saw that in the trace files the packets are delivered
normally. They only don't show up in the nam trace after the node that is
supposed to drop them...

Thanks for the help. After all I managed to do what I wanted. I created a new
type of queue that I use to do the job of a firewall. At least it works :P
