Grande Debian, y grande screen

Este finde pasado he actualizado la Debian del Slug de Etch a Lenny. En remoto desde Alicante, a ratos y a lo largo de los tres días (viernes-domingo). XDDD

Cómo molan dos cosas:

  • dist-upgrade de una plataforma no sé si minoritaria, pero desde luego menos extendida y probada que i386, sin problemas. Todo a la primera. Yay!
  • screen. En remoto con una hardware tan justito y lento como el slug hubiera sido imposible. Con screen: abre sesión, “aptitude full-upgrade”. Apaga el ordenador, cena con amigos, vuelves a casa, ssh, screen … mira, pregunta algo. Respondes. Apagas y a dormir. Al día siguiente otra vez … luego desde casa de un colega …

Son pequeños detalles que al final te acostumbras a ellos y creo que no los valoras en su medida, si no te paras a pensar lo coñazo que hubiera sido tener que reinstalar, que la actualización no fuera bien y al reiniciar no arrancara, o no haber podido ir entrando y saliendo de la sesión durante tres días sin tener que mantener el ordenador encendido y la conexión ssh abierta (y sin cortes con un 3G de Yoigo!).

Bravo!

Adiós mldonkey…

…hello rTorrent!

In the end mldonkey was too heavy for the slug. While downloading just one or two torrents it behaved quite well, but with some more and one of them big (>1Gb) it started eating up more and more memory and the slug became… sluggish. X-D

So I’m trying with different alternatives. Right now I’m running rTorrent on the server and nTorrent as a GUI on my Mac. Looks promising. :-)

Mi nuevo servidor

Ladies and gentleman, let me please introduce you to my new server, the one I’ve been blogging about lately:

What? You don’t see it? Yes! The small grey box on top of the iomega disk, slightly bigger than the Fonera

In case you don’t know it yet, it’s a Linksys NSLU2, a small device around $100 that comes with two USB2 ports and an ethernet connection. Plug an external USB hard drive to it and it’ll become available over the network like a NAS share. And the best part is: you can flash its firmware and install Debian!! :-D

It’s not that powerful, it has an XScale (ARM) processor at 266Mhz and only 32Mb of RAM. There are pages explaining how to install up to 256Mb. Nevertheless, it works and is small, doesn’t make noise, and has a small electrical consumption.

Up to now I’m running the following on it and it works quite well:
