Re: [ns] Bug in ns-2.1b7?

[Vikram Kanodia <kanodia@ece.rice.edu>]

 Thank you so much!!...i thought i was the only one who had observed this
bug...i had written apost earlier about this but it seemed no one else got
the problem...

I also wrote to debjyoti and he said that it was the users responsibility
to initilaise rng.....i compromised by adding the line rng_ as the first
line of the method command in pareto.cc and recompiled...no problems
since....
