[ns] Running TCP scripts!!!!

[Vakul Goel <goelvakul@yahoo.com>]

Hi folks..

I was trying to run the inbuilt tcl script tcp-int.tcl.. and I gave the
command as 

ns tcp-int.tcl 

at the command prompt. I gave this command inside the ../tcl/ex
directory..

But it is giving me the follwing error..

n0=0
n1=1
n2=2
n3=3
variable class already exists
    (_o86 instvar line 1)
    invoked from within
"$self instvar -parse-part1 $var"
    (procedure "_o86" line 18)
    (Agent set line 18)
    invoked from within
"$udp1 set class 1"
    (file "tcp-int.tcl" line 44)

Since I have been strruct in theis problem for a while now; I would
greatly appriciate if some one can help me in this regard.. 

Thanks in advance for your time..

Vakul
