Hemos aprendido a utilizar varios incluso un gestor gráfico (Filezilla) y a través de un cliente web con (webmin).&lt;br /&gt;
En GNU/linux te viene instalado por defecto un cliente FTP que se usa por consola o pro una interfaz. Uso:&lt;br /&gt;
#ftp localhost&lt;br /&gt;
user:&lt;br /&gt;
pasword:&lt;br /&gt;
ftp&amp;gt;&lt;br /&gt;
Y ya estaríamos conectados y preparados para transferir archivos.&lt;br /&gt;
Podemos utilizar los siguientes comandos:&lt;br /&gt;
-?&lt;br /&gt;
-ascii (para texto plano: txt, html, css, xml...)&lt;br /&gt;
-binary (para resto de archivos: jpg, gif, odt...)&lt;br /&gt;
-cd&lt;br /&gt;
-lcd&lt;br /&gt;
-chmod&lt;br /&gt;
-!chmod&lt;br /&gt;
-close&lt;br /&gt;
-delete&lt;br /&gt;
-mdelete&lt;br /&gt;
-mkdir&lt;br /&gt;
-dir&lt;br /&gt;
-!dir&lt;br /&gt;
-ls&lt;br /&gt;
-prompt&lt;br /&gt;
-pwd&lt;br /&gt;
-!pwd&lt;br /&gt;
-quit&lt;br /&gt;
-rename&lt;br /&gt;
-rmdir&lt;br /&gt;
-size&lt;br /&gt;
&lt;br /&gt;
Pero los mas importantes son:&lt;br /&gt;
&lt;br /&gt;
-get (para descargar un archivo)&lt;br /&gt;
-mget (para descargar varios archivos)&lt;br /&gt;
-put (para subir un archivo)&lt;br /&gt;
-mput (para subir varios archivos)&lt;br /&gt;
&lt;br /&gt;
para saber mas ordenes permitidas utilizar la orden:&lt;br /&gt;

&lt;br /&gt;
&lt;ul&gt;
&lt;li&gt;Instalamos dhpc3-server:&lt;/li&gt;
&lt;ul&gt;
&lt;li&gt;#apt-get install dhcp3-server&lt;/li&gt;
&lt;/ul&gt;
&lt;li&gt;Editamos el fichero /etc/dhcp/dhcpd.conf:&lt;/li&gt;
&lt;ul&gt;
&lt;li&gt;#gedit /etc/dhcp/dhcpd.conf&amp;nbsp;&lt;/li&gt;
&lt;/ul&gt;
&lt;li&gt;cerramos y reiniciamos el servidor:&lt;/li&gt;
&lt;ul&gt;
&lt;li&gt;&amp;nbsp;#/etc/init.d/isc-dhcp-server restart&lt;/li&gt;
&lt;/ul&gt;
&lt;/ul&gt;
Comprobaciones del buen funcionamiento:&lt;br /&gt;
&lt;br /&gt;
&lt;ul&gt;
&lt;li&gt;Para comprobar errores:&lt;/li&gt;
&lt;ul&gt;
&lt;li&gt;#gedit /var/log/syslog&lt;/li&gt;
&lt;/ul&gt;
&lt;li&gt;Para comprobar si se ejecuta el proceso&lt;/li&gt;
&lt;ul&gt;
&lt;li&gt;#ps -ef | grep dhcp &lt;/li&gt;
&lt;/ul&gt;
&lt;li&gt;Para ver los contratos que has ejecutado:&lt;/li&gt;
&lt;ul&gt;
&lt;li&gt;#&amp;nbsp; grep -v ^# /etc/dhcp/dhcpd.conf | grep -v ^$&lt;/li&gt;
&lt;/ul&gt;
&lt;/ul&gt;
Comandos interesantes para esta practica:&lt;br /&gt;
&lt;br /&gt;
&lt;ul&gt;
&lt;li&gt;route: para la puerta de enlace&lt;/li&gt;
&lt;li&gt;ifconfig:para ip, mascara de red, red de difusion...&amp;nbsp;&lt;/li&gt;
&lt;/ul&gt;
Cosas a tener en cuenta:&lt;br /&gt;
&lt;br /&gt;
&lt;ul&gt;
&lt;li&gt;Asegurarse de la configuración manual (que coincidan la ip, mascara de red, dns, puerta de enlace)&lt;/li&gt;
&lt;li&gt;Asegurarse de al editar&amp;nbsp; &quot;dhcpd.conf&quot; comprobar las llaves {} los puntos coma ;&lt;/li&gt;
&lt;/ul&gt;
&lt;ul&gt;
&lt;/ul&gt;

&lt;ol&gt;&lt;ul&gt;
&lt;li&gt;#apt-get install dhcp3-server&lt;/li&gt;

&lt;li&gt;&lt;b&gt;Editamos el fichero /etc/dhcp/dhcpd.conf&lt;/b&gt;&lt;/li&gt;

&lt;li&gt;#gedit /etc/dhcp/dhcpd.conf&amp;nbsp;&lt;/li&gt;
&lt;/ul&gt;
&lt;/ol&gt;
&lt;ul&gt;
&lt;li&gt;&lt;b&gt;Añadimos el rango de dir. IP que queremos asignar al final del doc.&lt;/b&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;ul&gt;&lt;ul&gt;
&lt;li&gt;subnet 172.20.0.0 netmask 255.255.0.0&lt;br /&gt;{&lt;br /&gt;range 172.20.202.160 172.20.202.169;&lt;br /&gt;}&lt;/li&gt;
&lt;li&gt;&lt;i&gt;(Importante que tenga la misma red que el equipo)&lt;/i&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;/ul&gt;
&lt;ul&gt;
&lt;li&gt;&lt;b&gt;Reiniciar el servidor:&lt;/b&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;ul&gt;&lt;ul&gt;
&lt;li&gt;#/etc/init.d/isc-dhcp-server restart&lt;/li&gt;

&lt;ul&gt;&lt;ul&gt;
&lt;li&gt;#ps -ef | grep name&lt;/li&gt;
&lt;li&gt;#vi /var/log/syslog&lt;/li&gt;
&lt;/ul&gt;
&lt;/ul&gt;
&lt;ul&gt;
&lt;li&gt;&lt;b&gt;reiniciamos la tarjeta de red y en terminal comprobamos&lt;/b&gt;&lt;/li&gt;

&lt;li&gt;Para configurar las DNS en linux existen 2 formas:&lt;/li&gt;
&lt;ul&gt;
&lt;li&gt;Manual: (modo comando)&lt;/li&gt;
&lt;ul&gt;&lt;ul&gt;
&lt;li&gt;&lt;b&gt;/etc/resolv.conf&lt;/b&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;/ul&gt;
&lt;/ul&gt;
&lt;/ul&gt;
&lt;ul&gt;&lt;ul&gt;
&lt;li&gt;Gráfico:&lt;/li&gt;
&lt;ul&gt;&lt;ul&gt;
&lt;li&gt;Desde conexiones de red en ajustes de ipv4&lt;/li&gt;
&lt;/ul&gt;
&lt;/ul&gt;
&lt;/ul&gt;
&lt;/ul&gt;
&lt;br /&gt;
&lt;ul&gt;
&lt;li&gt;Para crear un servidor de DNS utilizamos &quot;bind9&quot;, para ello bien lo instalamos desde el centro de SW o linea comando:&lt;/li&gt;
&lt;ul&gt;&lt;ul&gt;&lt;ul&gt;
&lt;li&gt;&lt;b&gt;apt-get update&lt;/b&gt;. &lt;i&gt;(para actualizar los repositorios)&lt;/i&gt;&lt;/li&gt;
&lt;li&gt;&lt;b&gt;apt-get install bind9&lt;/b&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;/ul&gt;
&lt;li&gt;para saber que bind9 se esta ejecutando escribiremos en terminal:&lt;/li&gt;
&lt;ul&gt;&lt;ul&gt;
&lt;li&gt;&lt;b&gt;ps -ef | grep bind&lt;/b&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;/ul&gt;
&lt;li&gt;para detener iniciar o reiniciar bind9 escribiremos:&lt;/li&gt;
&lt;ul&gt;&lt;ul&gt;
&lt;li&gt;&lt;b&gt;/etc/init.d/bind9 (stop/start/restart)&lt;/b&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;/ul&gt;
&lt;/ul&gt;
&lt;/ul&gt;

&lt;u&gt;&lt;b&gt;nslookup &lt;/b&gt;&lt;/u&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Te permite hacer peticiones sobre servidores de DNS.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
2 tipos:&lt;/div&gt;
&lt;ul&gt;
&lt;li&gt;No interactivo:&lt;/li&gt;
&lt;ul&gt;
&lt;li&gt;#nslookup &quot;nombre dominio&quot; (te devuelve la I.P.)&lt;/li&gt;
&lt;li&gt;#nslookup &quot;I.P.&quot; (te devuelve el nombre del domino)&amp;nbsp;&lt;/li&gt;
&lt;/ul&gt;
&lt;/ul&gt;
&lt;br /&gt;
&lt;ul&gt;
&lt;li&gt;Interactivo:&amp;nbsp;&lt;/li&gt;
&lt;ul&gt;
&lt;li&gt;#nslookup &quot;Servidor DNS (opcional)&quot;&lt;/li&gt;
&lt;li&gt;a partir de aqui puedes usar diferentes comandos en el orden que desees, ejemplos:&lt;/li&gt;
&lt;ul&gt;
&lt;li&gt;#&quot;I.P.&quot; (te da el nombre del dominio)&lt;/li&gt;
&lt;li&gt;#&quot;nombre&quot; (te da la I.P.)&lt;/li&gt;
&lt;li&gt;#set type =SOA (tiempo,&amp;nbsp; nombre y correo del propietario)&lt;/li&gt;
&lt;li&gt;#set type =NS (DNS)&lt;/li&gt;
&lt;li&gt;#set type&amp;nbsp; =A (I.P., nombre)&lt;/li&gt;
&lt;li&gt;#set type =MX (servidores de correo)&lt;/li&gt;
&lt;/ul&gt;
&lt;/ul&gt;
&lt;/ul&gt;
&lt;ul&gt;
&lt;li&gt;Anotación: un dominio puede tener varias direcciones&amp;nbsp; I.P.&lt;/li&gt;
&lt;/ul&gt;
