Why do you have deb http://ftp.de.debian.org/debian etch main within your /etc/apt/sources.list and not deb http://ftp.nl.debian.org/debian etch main ? By the way i think you can comment it out with a #.

These three lines should be enough for the Debian current stable branch:
deb http://ftp.nl.debian.org/debian/ stable main
deb-src http://ftp.nl.debian.org/debian/ stable main
deb http://security.debian.org/ stable/updates main
