Hello,
I´m driving myself crazy with nam. I´m trying to do some simulation with different local area networks (LAN). The problem is that nam draws these networks very messy when I let it automatic position. And, when I try to fix the position with orient righg for example, it puts all LANs together is there any way of setting the position of nodes? Is anyone using a different tool to visualize the networks? Thank you very much!!

Hello, I´m doing my first steps in ns2. I´m trying to construct a protocol for ARQ. After some tries, I´ve managed to compile it. The thing is that when I run the .tcl script I have the following message: Scheduler: attempt to schedule an event with a NULL handler. Don't DO that at time I guess it´s because an object is sending a packet with handler=NULL. My problem is that I don´t really know who is doing it, since when the handler arrives to the Scheduler function I´ve lost all context. I dont pretend you to solve my problem, I just would like to know if there´s any non-written procedure for this situation to trace who´s doing it back.. Than you in advance.
