Here is how i made the patch for inclusion:

git config --global user.name "Peter Holik"
git config --global user.email "peter AT holik.at"

check kernel out with git

git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git

first i had to export usbnet_get_ethernet_addr from usbnet.c
and to fix cdc_ether.c

git commit -am "export get_ethernet_addr from cdc.ether.c in usbnet"

then copy my new driver int51x1.c to /usr/src/linux-2.6/drivers/net/usb/ and modify /usr/src/linux-2.6/drivers/net/usb/Kconfig and /usr/src/linux-2.6/drivers/net/usb/Makefile

git add /usr/src/linux-2.6/drivers/net/usb/int51x1.c

git commit -am "usb driver for intellon int51x1 based PLC like devolo dlan duo"

git format-patch -s origin/master

Then mail the created file to linux kernel mailinglist:

cat 0001-export-usbnet_get_ethernet_addr-from-usbnet-and-fixe.patch | \
mail linux-kernel@vger.kernel.org

cat 0002-usb-driver-for-intellon-int51x1-based-PLC-like-devol.patch | \
mail linux-kernel@vger.kernel.org

Many thanks to the guys at linux-kernel@vger.kernel.org for suggestions and improvements.

Undo last commit with git reset --soft HEAD^

My driver will be part of linux kernel 2.6.31

Clusterssh opens for each connection a xterm and sends a keystroke to each window.

You can also work in only one xterm.

#> apt-get install clusterssh

I use approxd for caching .deb's using port 9999. This port is not reachable by all my hosts,
therefore i use remote port forwarding from ssh.

I can type

#> cssh -o "-R9999:approxy:9999" host1 host2 host3

or create a default config

#> cssh -u > $HOME/.csshrc

You can define different clusters aliases. Each alias consists of some hosts:

clusters = apt mon
apt = host1 host2 host3
ssh_args= -x -o ConnectTimeout=10 -R9999:approxy:9999

now i only type

#> cssh apt


a small patch makes "retile windows" working for me:

I could not run the ubuntu live installcd and also the alternate hang sometimes. After a successful install X freezes. I tried to boot with various boot options. Only with acpi=off my system seams to working but with fan running and no battery info. An older knoppix was running, so i decided to install older ubuntu kernels and saw my system running with a gutsy kernel (2.6.22) but not with a hardy kernel (2.6.24).

What changed inside the kernel?

After searching a lot i found pci=nommconf.

It seams that something in the way pci is configured has changed.

Searching for a rescue system that creates a bootable CD to restore my system i found mkcdrec. Because sometimes things (mkcdrec/debian/ubuntu) changes and i had to test and patch for new mkcdrec versions, so i droped it.

Then i started to make a live CD with debian-live and make my install script by myself. I also dropped it (long boottime and had too much to hack to let it work like i wanted).

Now i had the idea to build my own script that tar's my system and builds a bootable cd. I liked the idea of initramfs to extend it like i will and it boots much faster. The only drawback is that all things are hardcoded and have to be changed for every system i backup. But its only a single script: Read More...
