Subject: [Udpcast] loading modules per default
Message-ID: <4548787F.2040307@insecma.de>

Hello

I want to load some kernel modules per default.
I have add lines to "/init" in the /usr/lib/udpcast/tmpl-tree.

----- Ex.:
!/bin/sh

#mount -t devfs none /dev
modprobe sata_sis            <--- This is my new line
modprobe floppy
modprobe uhci-hcd
modprobe ohci-hcd
modprobe usbkbd
mount -t sysfs none /sys
/bin/udpc_dialog init
exec /bin/init
-----------

After making the initrd-image, and booting per PXE this image,
- i have include a prescript to make a pause before the menue appaers
(prescript: read dummy (for continue after keystroke)
At this time i activate a virtual console on ALT-2
and with lsmod my module isn't in memory.

How/where can/must i include my modprobe line to load it as soon as 
possible?

greeting
Uwe

I finally figured out the problem.  Thanks to all those who responded.
 In case you're in the same boat, here are the details:

After discovering the cast-o-matic tool (absolutely brilliant), I got
the idea to put in some modprobe commands in the "commands to be
executed before the udpcast menu" box on the second cast-o-matic page.
 I put in the following commands:

modprobe uhci-hcd
modprobe ohci-hcd
modprobe usbkbd

I'm not sure which or if all of them fixed the problem, but I was then
able to use the keyboard when booting udpcast.

So far the software has worked great!  goodbye zenworks, hello udpcast.

I've done some googling and found a few posts which seemed to indicate
that udpcast shouldn't have problems working with a usb keyboard.
Nonetheless, when I boot a pc from the cd or pxe, the keyboard does
not work.  Where should I start in troubleshooting this problem?  I am
very much a linux noob, but if someone can get me started, I believe I
can stumble my way through it.  Thanks.

Message-ID: <58110.192.168.1.72.1162839150.squirrel@192.168.1.241>

I'm C a programmer, looking for Linux UDP multicast programming
documentation.
Early I'm write some UDP multicast program for WIN32, using API, it is
working on NT4.0 (loop back does not work, you can not switch off own
packets), W2K and WINXP - where I/O completion port is exist.
In WIn32 API you can simply setup an UDP socket, bind on apropriate
interface address and after using IOCTL set ADD_MEMBERSHIP/DROP_MEMBERSHIP
you can "join" to many groups _ at most I have tested is 4 groups like
224.0.0.xxx on the same port number (for example 6000).
In Linux I had managed to use multicast UDP port but, it seem to be that
it could not "join" to many groups, to receive packets, only one and you
should bind on it (for example on 224.0.0.10:6000)!
Is this right? One UDP socket could receive UDP packets only from one
multicast group in Linux?

You can subscribe to as many multicast groups as you want. However, if 
you want to listen to the same address/port pair from two different 
programs, you need to set the SO_REUSEADDR flag before binding the 
socket. In C, you can do that as follows:

#include <sys/socket.h>
#include <netinet/in.h>
...
int reuse=1
...

if(setsockopt(master,SOL_SOCKET,SO_REUSEADDR,&reuse,sizeof(int)) < 0 ){
     perror("reuse");
     return -1;
}

Alain

I highly recommend the book "Unix Network Programming, Vol. 1: The 
Sockets Networking API" ISBN: 0131411551
It covers socket programming and has a chapter on udp multicast. 
Unfortunately it is windows winsock which does not conform to any 
standards and I am yet to find any thorough documentation on it.

I would suggest simply putting it into the prescript. Yes, this is not 
"as soon as possible", but it is the most "stable" alternative (i.e. it 
continues working, even after you upgrade udpcast).
Or is there any particular reason why you have to insert this module 
before anything else?

Regards,

Alain

Hi,


UDP CAST does not function with keyboard USB. 

Exists some solution for the problem?
