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

block ssh brute force attacs / prevent synflooding

With iptables module recent you can limit the count of tcp connection attempts. In my case i allow only 3 ssh connection attempts per minute. This stops script kiddies doing ssh brute force attacs.
iptables -N synflood
iptables -A synflood -p tcp --dport ssh -m recent --set --name SSH
iptables -A synflood -p tcp --dport ssh -m recent --update \
                     --seconds 60 --hitcount 4 --name SSH -j DROP

iptables -A INPUT -p tcp -m state --state NEW -j synflood
iptables -A FORWARD -i $OUT -p tcp -m state --state NEW -j synflood

apt-get install isdnutils-base

because ippp0 sets a default route we change to ippp1:

mv /etc/isdn/device.ippp0 /etc/isdn/device.ippp1
mv /etc/isdn/ipppd.ippp0 /etc/isdn/ipppd.ippp1

/etc/isdn/device.ippp1 (remove '# REMOVE'):
LOCALMSN='XXXXX'
REMOTEMSN=
isdnctrl ihup ${device} on
isdnctrl secure ${device} off

/etc/isdn/ipppd.ippp1 (remove '# REMOVE'):
debug
name YYYYY

/etc/ppp/chap-secrets:
# client server secret IP addresses
YYYYY HOSTNAME PASSWORD ""
