apt-get install libgeoip-dev php5-dev php5-geoip php-pear
pecl update-channels
pecl upgrade-all
pecl install geoip

Add "extension=geoip.so" to your 'php.ini' (at the end of the file). My 'php.ini' is located at '/etc/php5/apache2/php.ini'.

Download GeoIP Databases (if they aren't there already):

cd /usr/share/GeoIP
wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz && gunzip GeoLiteCity.dat.gz
wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCountry/GeoIP.dat.gz && gunzip GeoIP.dat.gz

Unfortunately there is something wrong with the paths, so I had to rename one of the files to make it work:

mv GeoLiteCity.dat GeoIPCity.dat

You can see all database files with the following command:

<?php
var_dump(geoip_db_get_all_info());
?>

I couldn't figure out where to change this list. Maybe I will find a way in the future...

Finally let's see where the client is located:

<?php
var_dump(geoip_record_by_name($_SERVER['REMOTE_ADDR']));
?>

# gcc -o code code.m -I /usr/include/GNUstep/ -L /usr/lib/GNUstep/ -lgnustep-base -fconstant-string-class=NSConstantString

But, in my case there was an error: 'error: #error The current setting for native-objc-exceptions does not match that of gnustep-base ... please correct this.'
To solve this problem, do the following:

# vim /usr/include/GNUstep/GNUstepBase/GSConfig.h

:set nu

Go to line number (in my case) 221, or search for:

#define BASE_NATIVE_OBJC_EXCEPTIONS 1

Replace the line with:

#define BASE_NATIVE_OBJC_EXCEPTIONS 0

Now the compiler should work without problems!

# apt-get update && apt-get upgrade

# apt-get install memcached php5-memcache

# /etc/init.d/apache2 restart

Now test it. Start a new memcache instance:

# memcached -u root -d -m 24 -l 127.0.0.1 -p 11211

This instance starts as root user using 24 MB as maximum cache size, listening on port 11211.
On my system, I have this process running now:

13919 ? Sl 0:00 /usr/bin/memcached -m 64 -p 11211 -u memcache -l 127.0.0.1

We can test our running memcache process by connecting via Telnet:

# telnet 127.0.0.1 11211

An overview of the availiable commands, you can find here: http://lzone.de/articles/memcached.htm
If you like to change your default memcached configuration, do the following:

# vim /etc/memcached.conf

Don't forget to restart memcached afterwards:

# /etc/init.d/memcached restart

At this point you would have to start all memcached instances manually. That's a thing I wouldn't like to worry about. So move the commands to rc.local:

# vim /etc/rc.local

Add lines like this before 'exit 0':

memcached -u your-user-name -d -m 16 -l 127.0.0.1 -p 11211

Make sure every instance listens on a different port. For example: 11211, 11212, 11213... etc.

# apt-get update

# apt-get install debconf

# dpkg-reconfigure locales

# adduser christoph

User christoph will be able to gain access via SSH just as every other user.

# pw usermod christoph -G wheel

By putting this user in de group wheel, the user gains the right to change to root via:

# su

# sysinstall

# vi /etc/rc.conf

hostname="shiva.local"
ifconfig_em0="inet 10.0.0.10 netmask 255.255.255.0"

# /etc/netstart
