Download stock debian linux kernel source from apt.
Untar the linux source found in /usr/src.
Enter kernel source directory.
Edit Makefile and add for example 'netboot' to extra version

#apt-get install build-essential
copy the config file from /boot directory to the kernel source directory
#make oldconfig

#make menuconfig
Under networking add dhcp options as buildt in.
under filesystems add nfs and nfs root as buildt in.
A copy of a working config can be found here.

This is some data gathered while doing some performance testing on the disks.
My setup.
-----------------

All servers are running debian Lenny.

Fileserver:
- Role is iscsi target server. ietadm version 0.4.17
- Tyan motherboard, 512MB ram, Intel(R) Pentium(R) D  CPU 2.66GHz, 3ware 9550SX raidcontroller, 4 sata disks in raid 10.

Xen servers:
- Role is xen dom0's.

Allways liked the idea about clustered machines.
Bought some Via Mini-Itx cards...why ? The answer is simple, atleast to me it
is. The price is ok (the most expensive part yet is the Cisco 2950, but the
plan is to replace it with 2 smaller switches:), nice power consumption, perfect
size (17x17cm), and no fan's to create noise.

The idea was to build something like this,
and a 'reallife' picture of the server now looks like this

As everyone else I wanted Adsl,
but since your line length cant be more than 5km to the telephone central it couldn’t be done, they said (the length to me is 11km from the central).
This winter I (2003) I started thinking about making a long distance wireless link, and a lot of people started smiling when I told about my idea.
The idea was to find a nice person who lived somewhere where adsl was available, and that he's (or her's;-) house was visible from my house.
