Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I have a linux workstation which has to stream huge MULTICAST traffic (mjpeg video) over a LAN.
In order to avoid multicast flooding, I have connected all the hosts (including the streamer) to a layer-3 switch with IGMP-snooping support. Therefore, I need that the streamer operates as multicast router.
I've noticed that my compiled kernel (2.6.x) isn't configured to work as a multicast router (CONFIG_IP_MULTICAST, CONFIG_IP_MROUTE etc. are not set) so, before starting a new kernel compilation/optimization (that could require some time) I would ask if this sequence of operations is correct, in order to make all work (without wasting too much time, since I already suppose that there is additional stuff to do):
1) firstly I recompile the kernel enabling MC support
2) then I install a MC routing daemon. I've found PIMd, mrouted and SMCRouter: which one do you suggest for 2.6.x kernel?
3) in order to make sure that the workstation is now operating a MC router i examine the result of this ping: ping 22.214.171.124
4) is there anything that I should check under /proc/net?
5) after 1,2 the layer-3 switch must detect the workstation's host as a MC router, right?
6) when streaming multicast traffic I can check if IGMP membership queries (not reports) are periodically sent from the workstation
Is this a good way of proceeding? Any help would be greatly appreciated,
