[ns] ns-2.1b6 on Linux

[Szabo Tibor <tipcsi@sch.bme.hu>]

Hello,

I have installed ns-2.1b6 on a Linux system, and when trying to run a
tcl script I receive the following:

ns: _o37 unknown-flow 0 1 0: no value given for parameter "hashbucket" to
"_o37"
    (_o37 unknown-flow line 1)
    invoked from within
"_o37 unknown-flow 0 1 0"

I have searched the word "hashbucket" in the code of ns, and it appears
only twice, and what is more, both are commented. To make sure, I have
deleted this commented lines and recompiled ns, but the same problem
persists. Now I think that it's more than strange. Could anyone help me?

Thanks in advance,

Tibor
