Re: Re: [ns] how to dump routing talbe?

[Andrea Josi <mr_josi@yahoo.it>]

Hi,
I believe that a simpler way to write the nodes'
routing tables of that simulation would be to
"redirect" the result of the simulation into a file
from the command line:
when you run ns, instead of typeing 

                   ns vec.tcl

you could type

                   ns vec.tcl > log.txt

This has the effect of putting in the file "log.txt"
everything that was printed on the screen with the
other method.
Cheers,
                       Andrea.
