Debian: online network interfaces reconfiguration with fallback to previous values
While inside screen:
/etc/init.d/networking stop; sleep 5; /etc/init.d/networking start; sleep 30; cp interfaces.old interfaces; /etc/init.d/networking stop; sleep 5; /etc/init.d/networking start
Limiting apt-get download speed
create file /etc/apt/apt.conf.d/76download with content:
Acquire
{
Queue-mode "access";
http
{
Dl-Limit "25";
};
};
That limits apt-get to 25KB/s

A good ol' from Ubuntu *and* Debian bugs:
Dimitrios Symeonidis wrote on 2008-10-14: (permalink)
this bug will soon celebrate it's 3rd birthday. it's marked as confirmed, high importance, and reported upstream (debian). are we going to do something about it, or are we just waiting for debian to resolve this?
(Emphasis added for extra lulz)
SoX, yeah!

Remove comments and empty lines sed one-liner
sed -e 's/#.*//' -e 's/[ ^I]*$//' -e '/^$/ d'
...so I don't have to think of it again.
Deluge Torrent and Etch Backports
Simply wonderful.
I don't have to get it from testing and "break" my stable box with mixed trees!
backports as default, stable as fallback
Add to /etc/apt/sources.list:
deb http://www.backports.org/debian etch-backports main contrib non-free
Add to /etc/apt/preferences:
Package: *
Pin: release a=etch-backports
Pin-Priority: 750
Package: *
Pin: release a=stable
Pin-Priority: 700
Add to /etc/apt/apt.conf.d/00Cache:
APT::Cache-Limit "33554432";
APT::Default-Release "etch-backports";
Do:
apt-get update
apt-get dist-upgrade
htmldoc
htmldoc --size a4 --linkstyle plain --webpage --no-jpeg --tocheader ... --tocfooter ... --top 0 --bottom 20 --right 20 --left 20 -f book.pdf *.html

Apt pinning: installing unstable packages on stable Debian
Minimal sources.list configuration.
/etc/apt/sources.list:
deb http://security.debian.org/ etch/updates main contrib
deb-src http://security.debian.org/ etch/updates main contrib
deb http://ftp.de.debian.org/debian stable main non-free contrib
deb http://ftp.de.debian.org/debian testing main non-free contrib
deb http://ftp.de.debian.org/debian unstable main non-free contrib
When updgrading, stable versions of packages need to stay on stable. unstable versions are usually newer, so they overwrite stable versions if this is not properly handled with using Pin-Priority as stated below. If not explicitly requested, "apt-get install" installs stable version of a package.
/etc/apt/preferences:
Package: *
Pin: release a=stable
Pin-Priority: 700
Package: *
Pin: release a=testing
Pin-Priority: 650
Package: *
Pin: release a=unstable
Pin-Priority: 600
To install f.e. unstable version of a package with dependencies from unstable as well (preferred method, AFAIK), do the following:
apt-get install package -t unstable
To install the same package, but to resolve it's deps from stable:
apt-get install package/unstable
