   MNC - Multicast NetCat

                            ------------------------



1. Introduction



mnc is a simple, one-direction-at-a-time, "netcat"-like application using

multicast. The aim is to provide a tool for easy debugging and testing when

setting up a multicast network or host. MNC supports IPv4 and IPv6

any-source-multicast and single-source-multicast, but depending on your

platform some of those features may not be available:

       

       L = Listen (Implies IGMP/MLD mupport)

       S = Send

       | Win2k3   |  L + S   |  L + S   |    S     |    S     |

2. Supported platforms



As of September 2004, mnc has been compiled and tested with Linux 2.6.8

kernels, the BSD KAME stack and Windows XP Profesional. Currently automatic

interface selection does not work on a KAME-based host and you will need to

specify the interface when in listening mode.



3. Installing mnc from source on UNIX:



	./configure ; make ; make install



4. Compiling from source on Windows:



nmc is compilable with free utilities available from Microsoft. You need to

download and install the free (as in beer) MS Visual C++ command-line tools

from:

	

	http://msdn.microsoft.com/visualc/vctoolkit2003/



and the SDK relevant to your platform from:



	http://www.microsoft.com/msdownload/platformsdk/sdkupdate/



You can run a Visual C++ command-line session, and use:



	cl /DWINDOWS=1 /TC /c *.c 

	link /fixed /out:mnc.exe *.obj ws2_32.lib



to compile a working mnc.exe. The Windows version of MNC does not yet fully

support IPv6 due to underlying limitation in the Operating System.



5. Reporting problems



Any problems, bugs or suggested features should be mailed to colm
