[ns] Scenario generator bug report

[Michael Welzl <michael@tk.uni-linz.ac.at>]

There seems to be a problem with the scenario generator and version
2.1b6 of ns; the example scripts create tcl files which use an ns
command called
duplex-link-of-interfaces

... and this command does not seem to exist any longer.
I tried exchanging it with a plain duplex-link, and it works.
Are interfaces really needed in the scenario generator?
