open up the core file and see what does the stack tracing say. Maybe there
is a bug that you can fix it. Send the stack track and I'd be interested
to see it too.

Hi All,
As an example AODV new trace format logs REQUEST both in ARP level and

now I wonder, which one of the trace files are accurate? which

the best way to practice this, is to create a user with low privilages to
only a subdirectory in FS, an then install NS-2. if it tries to access

yet again, I don't think if it conflicts with anything else, I

one thing you can do is to delete any (object files) .o files from setdest
