Re: [ns] problem with ns

[Parveen Kumar Patel <ppatel@cs.utah.edu>]

I am doing just that. I am able to create my node using the existing
tcl files for DSR. I get this error only if i instantiate a particular
class in the class declaration of my agent. if i change this variable to
some other type of variable it works, e.g. i am able to do some limited
functionality if i make it a nsaddr_t. 

what exactly is it that causes the port Classifier in ns to raise this
error?

thanx,
-parveen.
