Actually, the default routing interface can be anything you want.
For modem users, it is ppp0. I can't assume that the computer is
connected to the internet through its ethernet card.
Look at the "route" command to see what I mean.

Most programs never ask you "what is your default routing interface?.
So, I know that there is a way to do it, and it would make our deamon
much more user-friendly, instead of "write the interface in the .anet file"...

No. Just something other than "cout" or "printf". From what I know, when
you output something, it is to some terminal device, which, in turn, may do
fun things like colors, highlighting and so on for displaying text on
screen. It's because, usually, scanf is blocking, and you can't call printf
until the user press return. So, basically, I'd like to be able to do
screen output like vim does on the terminal(with color, bold characters...).
