Bluetooth using the gui in Ubuntu

Bluetooth is of course a well-known mechanism for connecting mobile phones and pda’s to computers and laptops. It is low-power, easy to setup, and works out of the box on most systems. Until recently setting up serial over bluetooth in ubuntu/debian wasn’t a trivial task. I was by all means doable, but for many people meant creating and copying, downloading and tailoring some command-line scripts. This difficulty is mostly still noticeable when looking at the sheer amount of blogposts and articles and wiki’s about this setup. The tools are there (bluez has been in development for years) and work great, but setup is not for Joe / Jane Average.

When I revisited using my mobile phone’s GPRS modem on my netbook via bluetooth (an Acer Aspire One, running Ubuntu Intrepid, 8.10), I found hundreds of articles detailing the aforementioned edits… and a couple about achieving the same with a gui. The sysadmin-side of me prefers console solutions as these can be used over ssh (so I can set this up for others), my advocate-, user-and blogging-sides wanted a gui.

I found Blueman (http://blueman-project.org/). I first read about it last november (at version 0.6) and was impressed, at time of this writing it is now at 1.02 and working even easier than before, thumbs up!

In this article I’ll have a look at setting up Blueman “the easy ubuntu way”, i.e. mostly from a gui, with package signatures and without using a terminal (I will have to cheat though :-( ).

Lightweight & fast webmail client

My main home server is a measly pentium II class machine running (now) on Debian Etch. Not the fastest machine but it works, uses little power and is cheap while setup from left-overs. Among other things it serves me my email when not at home using RoundCube Webmail. With the low-end hardware I am using it is key to keep it as fast and lightweight as possible. The server is behind a DSL connection at home so compression comes in handy as well.

Pre-loading debconf values for easy installation

Debian’s configuration management might take some getting used to, but after you learn your way around /etc/{default,init.d,} it makes good sense.

Now when you have to do the same thing over and over again (ever said yes 25 times to Sun’s java license?), or you find that after a dist-upgrade your ldap configurations are gone because you pressed ‘enter’ one too many times…; you could either keep lots of tarballs or digg deeper. The latter could be done with debconf. Debconf keeps all answers to questions packages can ask during installation, both the ones you gave yourself and the implied or low-priority ones chosen by the packager.

You can set those values yourself quite easily, once you know how.
