[ns] what's appen when you type $ns node

[Davide]

hi @ all,

i'm learning to use ns-2 and i need to understand as well as possible how a
normal wired node works.
i've already read the manual section about nodes but when i'm trying to
analize the "Simulator instproc node" i haven't understood how the node can
be created, what is the "node_factory_" and then i don't know how to ad
another object between the "node entry" and the "classifier"

thaks in advance

Davide
