D-Link DP-301P+ Pocket Size Print Server

I bought today a D-Link DP-301P+, it may be a bit old, but does the job quite well. I think there are still many printers out there with parallel port (the one I use it is a copy machine).

It has a nice web-page to be able to configure, but also a build in telnet server. It can print text receiving via e-mail, and ftp too! I like it.

Transparent caching proxy

Let's say that you are a system administrator and your company is lacking enough bandwidth. You decide to start a caching web proxy to save bandwidth. But there is many workstations, and you don't want to reconfigure them one-by-one.

Here comes transparent proxy. Let's suppose you have already fired up squid on your router (witch is is linux box) and the final step is get transparency working.

Let's suppose your LAN is connecting to your box via eth1, then the magical iptables command is:

iptables -t nat -A PREROUTING -i eth1 \
-p tcp --dport 80 -j REDIRECT --to-port 3128


And voila! Your clients now using your proxy, without knowing about it.:)

Witch package provedies that file?

Let's say that you have edited a file and now you want to find out how the original looked like. You may think OK! I'll check it in the original package. But ohh... My file belongs to witch package? Heeelp!!

There's a way to find this out. For example you want the package's name whom provides the file /etc/init.d/checkfs.sh then the command for you is

stone@skynet:~$ sudo dpkg -S /etc/init.d/checkfs.sh 
initscripts: /etc/init.d/checkfs.sh
stone@eldorado:~$

so initscripts provides it!

This may work under all Debian based distros.

Fair NAT - Linux bandwidth sharper script

Fair NAT is a linux router shaper script which allows something like fair bandwidth sharing among clients in the local network.

With it you can add more bandwidth to interactive connections, limit P2P traffic, and control client wise bandwidth for your local network.

OpenGEU - When Gnome reaches Enlightenment

OpenGEU, previously known as Geubuntu, is a complete and fully functional operative system based on Ubuntu. OpenGEU, a project started and designed by the Italian artist Luca D.M.. OpenGEU mixes the power and simplicity of Ubuntu and parts of the Gnome Desktop with the wonder and astonishing eye-candy of Enlightenment DR17.

Try it! I personally like Enlightenment, I used it for years. It is was beautiful, and it is more beautiful nowadays, and it is very fast too. And putting it on Ubuntu it is something... phenomenal.
