[ns] problems with no-slot{} default handler

[jonkeim@law.princeton.edu (Jonathan S. Keim)]

hi all,

i'm using ns-allinone-2.1b7 to try to make a modified version of example3.tcl from the ns tutorial.  every time i run my script, i get the following error:

using backward compatible Agent/CBR; use Application/Traffic/CBR instead
using backward compatible Agent/CBR; use Application/Traffic/CBR instead

                slot 4: _o440
        -1 default
---------- Finished standard no-slot{} default handler ----------

i can't see anything opb
viously wrong in my code, so i'm sort of stumped.

if you would like a copy of the code, let me know.
