link dynamics bug

[Hyogon Kim <hkim@bellcore.com>]

Hi, I installed ns-2.1b2 on SunOs 4.1.4 platform, and I am 
having trouble modelling link going up and down. First, I found
a bug in tcl/rtglib/dynamics.tcl in line 208. It was written
"lindes" instead of "lindex". I fixed it and them recompiled,
but I still get other errors for all three below:

	#ns rtmodel Exponential {1 0.1} $n0 $n1
	ns rtmodel Deterministic {0.5 2.0 1.0 200.0} $n0 $n1
	#ns rtmodel Manual {2.0 down} $n0 $n1

the error message is 

	Unknown operation down or subbordinate operation failed

Did anyone try this and succeed? Or 2.1b2 is not stable yet
for link dynamics modeling? I will greatly appreciate any
tip.

Thanks in advance,
Hyogon
