First we make sure our system is up to date:

sudo apt-get update
sudo apt-get upgrade

Now we install all needed packages:

sudo apt-get install linux-source-2.6.31 kernel-package fakeroot kernel-wedge build-essential \
makedumpfile build-dep linux linux libncurses5 libncurses5-dev linux-headers-generic

We unpack the source files to a custom directory in our home directory:

mkdir ~/src
cd ~/src
tar xjvf /usr/src/linux-source-2.6.31.tar.bz2
cd linux-source-2.6.31

We want to reuse the existing config:

cp -vi /boot/config-`uname -r` .config

Now you can customize the kernel:

make menuconfig

Then we can build it:

make-kpkg clean
fakeroot make-kpkg --initrd --append-to-version=custom-1 kernel-image kernel-headers

Ensure that frame buffer drivers are loaded:

echo vesafb | sudo tee -a /etc/initramfs-tools/modules
echo fbcon | sudo tee -a /etc/initramfs-tools/modules

Install the new packages:

dpkg -i linux-image-2.6.31.4custom-1_2.6.31.4custom-1-10.00.Custom_i386.deb
dpkg -i linux-headers-2.6.31.4custom-1_2.6.31.4custom-1-10.00.Custom_i386.deb

This script creates users and requires this webserver setup:
addweb

You also need the following default files:
default-vhost
default-php5-fcgi-starte
php.ini

There is another script to delete users from apache and the system:
dellweb

Installation:

All files have to be saved in the same directory, to run the .sh files they must have proper rights:

chmod +x addweb.sh
chmod +x dellweb.sh

To run the scrips type:

sudo ./addweb username
sudo ./dellweb username

Then follow the dialog. On request the script could be writen dialog free as well.

First we refresh our package management and our packages:

apt-get update
apt-get upgrade

Then we have to install the basic packages:

apt-get install postgresql postgresql-server-dev-8.3 php5-pgsql

Now we have to do the basic setup of the postgresql server:

sudo -u postgres psql template1

Now you can define a passwort for the postgres user:

\password postgres

To leave the prompt enter:

\q

First we create a new user:

useradd -g ftpuser -d /var/www/pga -s /bin/ftp -m pga
chown pga.www-data /var/www/pga
chmod 750 /var/www/pga
mkdir /var/www/pga/conf
mkdir -p /var/www/pga/domain/{cgi-bin,exec,html,log,session,temp}
chmod 770 /var/www/pga/domain/temp
chmod 777 /var/www/pga/domain/session
chmod 700 /var/www/pga/domain/exec
chown -R pga.ftpuser /var/www/pga/*
rm -rf /var/www/pga/.b*
rm -rf /var/www/pga/.p*

Then we create a vHost for the new pga user:

cd /etc/apache2/sites-available/
vim pga

We add the following configuration:

<VirtualHost *:80>
        ServerAdmin webmaster@localhost
        SuexecUserGroup pga ftpuser
        ServerName www.domain.tld
        ServerAlias more.domains.tld
        DocumentRoot /var/www/pga/domain/html
        DirectoryIndex index.php index.html index.htm

        <Directory />
                Options FollowSymLinks
                AllowOverride None
        </Directory>

        <Directory />
                Order Deny,Allow
                Deny from All
        </Directory>

        <Directory /var/www/pga/domain/html>
                FCGIWrapper /var/www/php-fcgid-scripts/pga/php-fcgid-starter .php
                Options +ExecCGI
                order allow,deny
                allow from all
        </Directory>
        ErrorLog /var/www/pga/domain/log/apache_error.log

        # Possible values include: debug, info, notice, warn, error, crit,
        # alert, emerg.
        LogLevel warn

        CustomLog /var/www/pga/domain/log/apache_access.log combined
        ServerSignature On
</VirtualHost>

Now we create the fcgi configuration:

cd /var/www/php-fcgid-scripts/
mkdir pga
cd pga
touch php-fcgid-starter
chmod +x php-fcgid-starter
vim php-fcgid-starter

Now we add the configuration:

#!/bin/sh
PHPRC="/var/www/pga/conf"
export PHPRC
PHP_FCGI_CHILDREN=15
export PHP_FCGI_CHILDREN
exec /usr/bin/php5-cgi

We configure the proper rights:

chown -R pga.ftpuser /var/www/php-fcgid-scripts/pga
chmod 755 /var/www/php-fcgi-scripts/pga/php-fcgi-starter
chattr -V +i /var/www/php-fcgid-scripts/pga/php-fcgid-starter

We create a php.ini file for this vHost:

cd /var/www/pga/conf
wget http://www.naumann.cc/wp-content/uploads/2009/10/php.ini
chown root.root php.ini

Now we download the pgaPgAdmin interface:

cd /var/www/pga/domain/
su -m pga
wget http://downloads.sourceforge.net/project/phppgadmin/phpPgAdmin%20%5Bstable%5D/phpPgAdmin-4.2.2/phpPgAdmin-4.2.2.tar.bz2?use_mirror=mesh
tar xjvf phpPgAdmin-4.2.2.tar.bz2

Then we copy all files into the html directory:

mv phpPgAdmin-4.2.2/* html/

Now we have to configure the postgresql server for the usage of phpPgAdmin:

vim /etc/postgresql/8.3/main/postgresql.conf

Ennable the following line:

listen_addresses = 'localhost'

Create a new user for phpPgAdmin:

sudo -u postgres createuser -D -A -P myuser
sudo -u postgres createdb -O myuser mydb

Change the authentication settings in the following file to allow access via phpPgAdmin via this user:

vim /etc/postgresql/8.3/main/pg_hba.conf

Add this line:

local   all         myuser                             md5

before:

local   all         all                               ident sameuser

First we update our package manager:

apt-get update
apt-get upgrade

Now that we have a current system we can install the new package:

apt-get install ddclient

Select your dyndns provider from the list, for me it’s www.dyndns.com.

Enter the domain name that should be updated into the following field.

Enter your user name and password.

In the next dialog you have to enter the network device whos ip where the domain name should be resolved to.

For me this is eth0.

You can change the settings also via the config file:

vim /etc/ddclient.conf

My file looks as follows:

# Configuration file for ddclient generated by debconf
#
# /etc/ddclient.conf

pid=/var/run/ddclient.pid
protocol=dyndns2
use=if, if=eth0
server=members.dyndns.org
login=username
password='password'
host.dyndns.biz

First we have to install the imapsync package:

sudo apt-get install imapsync

Then we have to trigger the migration:

imapsync --syncinternaldates \
  --host1 mail.source.tld --authmech1 LOGIN --user1 user@domain.tld --password1 secret \
  --host2 mail.target.tld --authmech2 LOGIN --user2 user@domain.tld --password2 secret

Now drink a coffee , because this can take a while.

sudo apt-get install ntp ntpdate

Than we have to do some basic configuration:

echo "ntpdate ntp.ubuntu.com pool.ntp.org " >> /etc/cron.daily/ntpdate
sudo chmod 755 /etc/cron.daily/ntpdate
echo "server ntp.ubuntu.com" >> /etc/ntp.conf
echo "server pool.ntp.org" >> /etc/ntp.conf

Have a look at this page for more ntp Servers.

I had to change my timezone as well, this can be done by changing a symbolic link:

ln -sf /usr/share/zoneinfo/Europe/Berlin /etc/localtime

Just replace Europe/Berlin by your timezone. You can find more information about changing timezones here.

sudo apt-get install build-essential linux-headers-$(uname -r) subversion

Now we can add the madwifi drivers for the wlan chipset:

cd /usr/local/src
svn checkout http://madwifi-project.org/svn/madwifi/trunk madwifi
cd madwifi
make
sudo make install
sudo modprobe ath_pci

You can find some additional Information of putting madwifi into a kernel at this page. (German)

We have to do some additional configuration first we have to add the module to /etc/modules:

echo "ath_pci" >> /etc/modules

I added some scripts following the howto.

apt-get install screen

We add the following at the end of the configuration file:

vim /etc/screenrc

hardstatus string "%h%? users: %u%?"
startup_message off
hardstatus alwayslastline "Redmine: %-Lw%{= BW}%50>%n%f*   %t%{-}%+Lw%<"
bindkey -k k7 prev
bindkey -k k8 next

Now you can open a screen session:

screen
screen -r
-> resume a screen session
screen -x
-> join a screen session

When you start screen:

CTRL - A then CTRL - D
-> exit screen
CTRL - A then CTRL - C
-> new tab
CTRL - D
-> close window (when all are closed screen will be terminated)
CTRL - A then CTRL-D
-> exit screen without terminating tabs

First we open a shell and install the necessary packages to create kernels under ubuntu:

sudo apt-get install kernel-package build-essential libncurses5-dev bin86 subversion-tools

Get the newest vanilla kernel, best practice would be to put it into /usr/src.

cd /usr/src
wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.30.tar.bz2
tar xjvf linux-2.6.30.tar.bz2
cd linux-2.6.30

Now we can update the symlink:

rm -rf linux && ln -s /usr/src/linux-2.6.30 linux && cd /usr/src/linux

The we load the old configuration and then we launch the command line interface:

sudo cp /boot/config-$(uname -r) .config && yes "" | make oldconfig
cd /usr/src/linux-2.6.30
sudo make menuconfig

Now you can change what ever you want for you own custom kernel, after this we can clean the kernel and then we can trigger the creation of our new kernel:

sudo make-kpkg clean
sudo make-kpkg --revision eee701 kernel_image

If you want to know more about make-kpkg, have a look at this page. (German)
Some ubuntu specific information can be found here.

To install the kernel run:

sudo dpkg -i linux-image-2.6.30_eee701_i386.deb
