This directory contains an example of how a project using lwIP might
|
||
|
|
look. It is also the development platform of lwIP, since it can be run
|
||
|
|
as a user process under FreeBSD or Linux. There are also a number of
|
||
|
|
example applications (including a simple web server) in the apps/
|
||
|
|
directory.
|
||
|
|
|
||
|
|
Some short instructions on how to build and run lwIP on a FreeBSD or
|
||
|
|
Linux host. For FreeBSD, the tap interface must be enabled in the
|
||
|
|
kernel configuration and the kernel must be recompiled. The tap
|
||
|
|
interface is enabled by adding the line "pseudo-device tap" in the
|
||
|
|
kernel configuration. See Chapter 9 in the FreeBSD handbook for
|
||
|
|
instructions on how to build a custom FreeBSD kernel.
|
||
|
|
|
||
|
|
* Compile the code. This must be done by using GNU Make. Under
|
||
|
|
FreeBSD, GNU Make can be found in the ports collection under
|
||
|
|
/usr/ports/devel/gmake (type "make install distclean" to
|
||
|
|
install). Under Linux, GNU Make is the default "make".
|
||
|
|
|
||
|
|
> gmake (FreeBSD)
|
||
|
|
|
||
|
|
> make (Linux)
|
||
|
|
|
||
|
|
* The compilation process produces the executable file "simhost". To
|
||
|
|
run this, you have to be root.
|
||
|
|
|
||
|
|
> su (Type password for the root account)
|
||
|
|
# ./simhost
|
||
|
|
|
||
|
|
* The lwIP TCP/IP stack is now running with IP address
|
||
|
|
192.168.0.2. Some things that you can try:
|
||
|
|
|
||
|
|
To see the packets that are going to and from the lwIP stack, run
|
||
|
|
tcpdump:
|
||
|
|
|
||
|
|
# tcpdump -l -n -i tap0
|
||
|
|
|
||
|
|
You can ping lwIP:
|
||
|
|
|
||
|
|
> ping 192.168.0.2
|
||
|
|
|
||
|
|
For a telnet shell, run:
|
||
|
|
|
||
|
|
> telnet 192.168.0.2
|
||
|
|
|
||
|
|
Finally, "simhost" also includes a simple web server; the URL is
|
||
|
|
of course http://192.168.0.2/.
