Sounds good enough, unless you expect to test the kernel version of our 
OBOS stack!

The /dev/net/server is the driver gateway between apps linked against 
libnet.so (R5.0.x apps) or libsocket.so (BONE apps) and the userland 
version of the stack, hosted by net_stack_tester app.

That means for the OBOS stack to works, you *need* to start this app:

$ cd Desktop/OpenBeos/current/tests/add-ons/kernel/network
$ net_stack_tester &

Looks goods too.

Here lies the problems:
- the libraries should be place under a "lib" sub-folder, not at same 
level than apps. Create a "lib" folder here and move the libnet.so & 
libnetapi.so into it.
- we switch recently all our network tools to be BONE compatible, not 
R5 compatible. That means there are linked against *our* libsocket.so 
and libbind.so, not libnet.so anymore. So you should place x86.R1/beos/
system/lib/libsoket.so to the previous "lib" subfolder.
- As you are using the userland version of the stack, you have to tell 
our libsocket.so (that's true for libnet.so too) to use /dev/net/server 
driver (default is /dev/net/stack) to interface with the stack:

$ export NET_STACK_DRIVER_PATH=/dev/net/server

Last remarks :
- give a look at current/docs/develop/net/index.html
- we have a "ready to install and play with" networking kit package, 
it's maybe time we document how to use it.
  However, to build and assemble it:
  $ cd cd Desktop/OpenBeos/current/
  $ jam openbeos-networkingkit-cvs

  Then, you should find a package under packages/x86.R1/openbeos-
  But, beware, installing it will also install our drivers, some of 
them may overwrite an already installed one.
