proto_pptp_setup is responsible for loading the required modules to establish
a pptp connection to a foreign peer. The function checks whether all required
modules are already loaded, before actually loading them.
It seems that the filter being used to accomplish this, is not restrictive
enough in some cases. For instance when pptp nat helper modules are present on
a system, and already loaded before a pptp connection is enabled. Then the
search filter (possibly) returns the following for module=pptp, where actually
no matches are expected, resulting in the pptp.ko module not being loaded,
thereby failing to establish the pptp connection.
# module="pptp" ; grep "$module" /proc/modules

nf_conntrack_pptp 3072 1 nf_nat_pptp, Live 0x86cb9000

The search filter can be made more accurate/restrictive, by requiring the
occurance of the exact name of the module at the beginning of a line in
/proc/modules.
# module="pptp" ; grep "^$module " /proc/modules

This is the buildsystem for the OpenWrt Linux distribution.
Please use "make menuconfig" to configure your appreciated
configuration for the toolchain and firmware.
You need to have installed gcc, binutils, bzip2, flex, python, perl
make, find, grep, diff, unzip, gawk, getopt, libz-dev and libc headers.
Run "./scripts/feeds update -a" to get all the latest package definitions
defined in feeds.conf / feeds.conf.default respectively
and "./scripts/feeds install -a" to install symlinks of all of them into
package/feeds/.
Use "make menuconfig" to configure your image.
Simply running "make" will build your firmware.
It will download all sources, build the cross-compile toolchain,
the kernel and all choosen applications.
You can use "scripts/flashing/flash.sh" for remotely updating your embedded
system via tftp.
The OpenWrt system is documented in docs/. You will need a LaTeX distribution
and the tex4ht package to build the documentation. Type "make -C docs/" to build it.
To build your own firmware you need to have access to a Linux, BSD or MacOSX system
(case-sensitive filesystem required). Cygwin will not be supported because of
the lack of case sensitiveness in the file system.
Sunshine!
