Netfilter has a module that can be loaded to extend its functionality so it can understand the FTP protocol Once this module is active, it will see when FTP traffic is operating and needs to establish an incoming connection It can allow this specific connection to succeed without having to open any new ports..

The firewall we will be looking at here only relates to IP version 4. It is possible to build a firewall that supports IP version 6, but this is still a relatively new field. IP version 6 also brings its own complexities, which are outside the scope of this book.

Listing 13-13. Simplifying Interop Using Marshaling // interop_messagebox_marshaling.cpp #include <windows.h> #include <msclr\marshal.h> using namespace System; using namespace msclr::interop; public ref class MessageBoxClass { public: property String^ Message; property String^ Caption; int DisplayBox() { marshal_context context; return MessageBoxW( 0, context.marshal_as<const wchar_t*>(Message), context.marshal_as<const wchar_t*>(Caption), MB_OK); } }; int main() { MessageBoxClass m; m.Message = "Managed string used in native function"; m.Caption = "Managed Code Using Win32 Message Box"; m.DisplayBox(); } The call to MessageBoxW is a transition to native code, just as in the case where P/Invoke was used to call MessageBox. As long as the native functions are called infrequently and the main action is in the managed code, this form of interop makes sense. If all you have is a binary, you don t have any other options available to you. In the next section, you ll see how if you have access to the source for the native library and can recompile it, you can avoid the context switch between native and managed code.

You can view the list of rules being used by netfilter at any by time by issuing the command iptables L n. The L says to list all the chains and rules in the table, and n will skip DNS lookups and show IP addresses only. You will see output similar to that shown in Listing 10-2.

So now you re finally ready to test! Along the way, you ll take a look at the background dehydration process.

At this point, you ve seen how to call native functions in two ways from managed code using P/Invoke and by linking with the appropriate binary and including the appropriate header. You ve gotten a taste of the conversions that are used and some of the concerns when calling native code, such as pinning movable data.

Ln will list a table called n and is not the same as iptables L n, which will list the default table in numeric form. For this reason it is recommended that you always specify each parameter separately.
