[Click] Quick newbie questions

[Kurtis Heimerl]

Hello, my name is Kurtis Heimerl and I recently began a project using Click.


I'm running in user-level as my application is only a proof of concept, and
I've been unable to get insmod to load the kernel module correctly.

Right now I'm focused only on getting something working. I currently have 5
VMs set up in a star configuration, with the center running click.

I'm hoping for an answer to two questions:

Is there a default configuration for a simple IP router? There is a perl
script which generates an IP click config file, but it's seemingly for
kernel mode only. I suppose I could modify it, but what i'm looking for now
is a known working case to help me understand what's going on. I can't seem
to find a default config for user space IP routing.

Secondly, what are my losses for running in user mode? I had assumed the
main loss would be efficiency, but some elements seem to require kernel
mode. Is this set in stone, or simply the default behavior?

Thanks a lot!
