[ns] Nodes not viewable in NAM

[Martin McKenny <mkenny@mekb2.sps.mot.com>]

Hi All,

I am working through the NS tutorials. I am on example 2 and already I
have hit a problem.
The TCL script runs fine and NAM is called but then produces only a
blank screen. I have double
checked the TCL and it seems OK. There are no warnings or errors, Any
ideas anyone.....
