<p>By default, fink&#8217;s TeTeX installation does not enable Spanish language support, like hyphenation and translation of english strings in macros to spanish. To enable support for Spanish, edit the following file:</p>
<p><code>/sw/share/texmf/tex/generic/config/language.dat</code></p>
<p>and change the line that reads</p>
<p><code>%! spanish sphyph.tex</code></p>
<p>to</p>
<p><code>spanish sphyph.tex</code></p>
<p>Now, we need to tell TeTeX to reconfigure itself to accomodate the changes by running the following command as root:</p>
<p><code># texconfig init</code></p>
<p>The output resulting from running the previous command should give no errors and look like this:</p>
<p><code>...<br />

<p>The last step is trying to parse a TeX file using pdflatex and the Spanish language to see if it works. For example, try feeding the following TeX file to pdflatex:</p>
<p><code>\documentclass[11pt,a4size,twoside]{report}<br />
%Incluye soporte para graficos.<br />
\usepackage{graphicx}<br />
%Controla que el primer parrafo despues de una seccion este indentado.<br />
\usepackage{indentfirst}<br />
%Incluye soporte para los comandos \verb y \url.<br />
\usepackage{url}<br />
%Cambia el tipo de letra a Palatino con soporte para simbolos matematicos.<br />
\usepackage{palatcm}<br />
\usepackage[spanish]{babel}<br />
\setlength{\parskip}{3pt}<br />

\author{Felipe Alfaro Solana\Ricardo Osses Da Silva}<br />
\date{\today}<br />
\maketitle<br />
\chapter{Estudio de Viabilidad del Sistema}<br />
\section{Establecimiento del alcance del sistema}<br />
Nuestro cliente, de ahora en adelante \cliente, pretende implantar un sistema de informaci'on integral que le permita automatizar la operativa diaria derivada de la gesti'on y mantenimiento de los servicios de la Estaci'on de Esqu'i, entre los que se incluyen:</code></p>
<p><code>Gesti'on integral de reservas, tanto en lo referente a la estancia de usuarios en un hotel, como la compra o alquiler de equipo, contrataci'on de un seguro m'edico o de accidentes, etc.</code></p>
<p><code>\subsection{Estudio de la solicitud}</code></p>
<p><code>El cliente pretende implantar un sistema de informaci'on integral que automatice la operativa correspondiente a la parametrizaci'on del sistema, la gesti'on de intervinientes (clientes de la estaci'on de esqu'i, proveedores, etc.), gesti'on de compras y ventas de material (de esqu'i, sanitario, alimentaci'on, fungible, etc.), planificaci'on de cuadrantes horarios para los empleados, gesti'on de servicios (clases e instructores de esqu'i, alquiler de equipo, contrataci'on de seguro m'edico y atenci'on en pista, etc), soporte m'inimo de informes dirigidos a facilitar la toma de decisiones y evaluar la sitaci'on y la solvencia de la empresa.</code></p>
<p><code>Actualmente, no se han detectado restricciones de car'acter econ'omico, aunque la oferta presentada al cliente determinar'a si 'este acepta el desarrollo.</code></p>
<p><code>Respecto a las restricciones t'ecnicas y operativas, el cliente ha especificado las siguientes:</code></p>
<p><code>\begin{itemize}<br />
\item El sistema de informaci'on deber'a ser transportable e independiente, en la medida de lo posible, de la arquitectura hardware. Si en un principio se opta por una plataforma basada en procesadores IA-32 de Intel, deber'a ser posible, por ejemplo, poder migrar el sistema de informaci'on a una plataforma basada en un sistema iSeries de IBM, por ejemplo.<br />
\item El sistema de informaci'on deber'a permitir especificar distintos niveles de acceso al sistema, tales que permitan distinguir entre operadores de cada una de las distintas 'areas o departamentos (administraci'on, tienda, hotel, etc.), gerencia y administradores del sistema.<br />
\end{itemize}</code></p>
<p><code>No se han detectado restricciones de car'acter legal, exceptuando aquellas derivadas de la vigente ley de la protecci'on de las comunicaciones telem'aticas como la LSSI y leyes de protecci'on de datos de car'acter privado como la LOPD.</code></p>
<p><code>\end{document}</code></p>
<p>pdflatex should generate a beautiful typesetted PDF document as the result, formatted cleanly, translated into Spanish and with the correct hyphenation.</p>

<p>While reading the UNIX-HATERS Handbook, I read the following phrase:</p>
<blockquote><p>No, those were the real days of computing. And those were the days of Unix. Look at Unix today: the remnants are still there. Try logging in with all capitals. Many Unix systems will still switch to an all-caps mode. Weird.</p></blockquote>
<p>What&#8217;s more weird is that I tried logging in onto my Gentoo 2004.3 Linux system using all capitals and, to my surprise, the whole session switch to an all-caps mode: the output of the &#8220;ls&#8221; command, even the &#8220;vi&#8221; editor. Astonishing.</p>

			<content:encoded><![CDATA[<p>To allow for remote, Xvnc-based sessions from the network to a Linux machine using <em>vncserver</em>, we can leverage the <em>xinetd</em> infrastructure to dynamically, and on-demand, spawning Xvnc servers for incoming remote connections. To do so, create a file named <i>/etc/xinetd.d/xvncserver</i>:</p>
<pre>  # cat > /etc/xinetd.d/xvncserver
  service vnc
  {
    protocol    = tcp
    socket_type = stream
    wait        = no
    user        = nobody
    server      = /usr/bin/Xvnc
    server_args = -inetd -query localhost -once \
                  -geometry 800x600 -depth 16 \
                  -desktop fab.felipe-alfaro.com \
                  -securitytypes=none
  }</pre>
<p>Then, add the following line to file <i>/etc/services</i>:</p>
<pre>  vnc             5901/tcp</pre>
<p>Port 5901/tcp corresponds to the first display of an VNC server, that is, display :1. Thus, when using the vncviewer client, the :1 parameter must be passed to specify this display.</p>
<p>The last step is to restart the <em>xinetd</em> daemon by running:</p>
<pre>  # service xinetd restart</pre>
<p><b>NOTE:</b> For this to work, XDCMP support must be enabled for XDM/GDM/KDM or whatever login manager is being used. This is due to Xvnc using <em>-query localhost</em> in order to present a login screen.</p>
