Re: [ns] diff between Makefile.in, Makefile, makefile
Makefile.in is the real file to modify if you have to Makefile or makefile is created by configure, but only one should exists. The other makefile is makefile.vc, which is for Visual C++ in MS environment. Kavi priya K wrote: Hi all, I would like to know the difference between Makefile.in, Makefile and makefile.

Re: [ns] help..how to start ns?
That's a basic Unix/Linux question: you have to give the path to run. For example, type ./ns if you are at the directory you run make to build ns.

Re: [ns] Visualization tool for Wireless Networks
Hi Leo, can anyone give more information on Inspect and ad hockey .. which are visualizationtools for wireless simulations in ns2. i want to get hold of visualization tools for wireless network simulation in ns2. maybe you should state more clearly what information you're looking for. I mean, there are papers available on both of them, telling you quite a lot about the tools... And, BTW, there's also a third tool, Huginn (http://pi4.informatik.uni-mannheim.de/pi4/lib/projects/huginn/). For Huginn there's also a paper available (at the MSWiM 2005).

[ns] ns run time problem using pgm
Hi, had the following message output when trying to run a tcl script.

Im new to ns so this doesnt really make much sense to me at all.
Any ideas?
