Hi,

====================== I already sent this message, but I get troubles using the other email... ======================

I don't succeed in giving two options through apend boot cmdline. Here is my cmdline:

label u1auto kernel vmlu26 append initrd=udprd root=01:00 persoparams=oui lang=FR kbmap=FR dhcp=yes compr=lzop port=9002 umode=snd disk=/dev/hda1 auto_reboot=always enableDiskmodule=yes diskmodule=AUTO netmodule=AUTO udpcparam=--max-wait=300--min-receivers=2

A script is launched using predialog. It writes the /udpcfg.txt file.

With the above cmdline, I get:

udpsender -p lzop --file /dev/hda1 -P 9002 -i eth0 --max-wait=300--min-receiver=2

instead of

udpsender -p lzop --file /dev/hda1 -P 9002 -i eth0 --max-wait=300 --min-receiver=2

And it doesn't work.

===========================

I've tried:

And my predialog script does:

udpcparam=`echo "$udpcparam" | sed -e "s/|/ /g"` echo "udpcparam=$udpcparam" >> /udpcfg.txt

But it doesn't work. /udpcfg.txt contains ... umode=snd udpcparam=--max-wait=300 --min-receivers=2

And I get

Udp-sender 2007-12-28 --min-receivers=2: not found Using mcast address 232.168.52.210 Compressed UDP sender for /dev/hda1 at 192.168.52.210 on eth0 Broadcasting control to 192.168.52.255

and it fails.

How could I get both options working?

I did those tests using 2.6.23 kernel and udpcast-mkimage-20080107-1.i586, udpcast-20070602-1.i586 I'll try again using udpcast-20071228-1.i586 udpcast-mkimage-20080911-1.i586 kernel-udpcast-2.6.26.3-1.i586

Yes, that's what you typed... see above.

Makes sense.

^ You need a space there. Try putting the parameter between quotes to avoid it being interpreted as two parameters: udpcparam="--max-wait=300 --min-receivers=2"

...

And my predialog script does:

udpcparam=`echo "$udpcparam" | sed -e "s/|/ /g"` echo "udpcparam=$udpcparam" >> /udpcfg.txt

Why don't you put this directly into udpcfg.txt?

...

But it doesn't work. /udpcfg.txt contains ... umode=snd udpcparam=--max-wait=300 --min-receivers=2

correct (no need for quotes here, as the different parameters are line-separated)

...

And I get

and it fails.

Works for me (just tried it out by editing the SYSLINUX.CFG on a floppy image)

I know. But udpcparam=--max-wait=300 --min-receiver=2 doesn't work in boot cmdline.

I can't. The boot cmdline is put in /tftpboot/pxelinux.cfg/01-ADDRESS_MAC PHP web interface is used to build 01-ADDRESS_MAC the way I wan't to clone this or this.

It's a part of sambaedu3 project. I use udpcast in se3-clonage package.

Argh?

You're right. It's OK if I put: udpcparam="--max-wait=300 --min-receivers=2" in 01-ADDRESS_MAC
