Hi,
I'm using ns2.33 too. But I use piece-by-piece installation rather
than all-in-one. And I'm running ns2 on ubuntu Linux, with nam 1.13,
the latest release. I'm lucky enough to generate proper nam trace for
wire-linked scenarios as well as for some wireless scenarios,
including those adopted from Geris' tutorials some of which need
slight modification for new ns2 releases.
Below I'll paste a snippet from the trace file, generated by
exampl1b.tcl, for your reference.
