OK, first at all, you need to find out what IP’s are used on the routers of that LAN. You could use some tracing tools like the Advanced IP Scanner which you could download free from: http://www.advanced-ip-scanner.com/
You have to key in the IP Range of the LAN system like 192.168.1.1 to 192.168.1.254. This you could find (if you didn’t know already) using in Windows Command Prompt (CMD) or PowerShell the command: ipconfig /all

Installing software on Ubuntu is really easy but sometimes we can have problems to uninstall it if we have not used the Package Manager (Synaptic till Ubuntu 9.04 and later through the Software Center) or a .deb package. To fastly uninstall all the software you do not need or you are not fond of, you can type in the Terminal:
sudo dpkg -r your_file
An alternative and powerful way is typing:
sudo apt-get remove your_file
(where your_file it is the name of the software you want to remove)
or, if you want to completely cancel also the configuration files:
sudo apt-get --purge remove your_file
If you want to check what software is installed on you Ubuntu you can use:
dpkg --list
and you will obtain a complete list of software and a very short summary for each package. 
Hace unos días he encontrado esta nueva aplicación para Linux, se llama CLI Companion. Aunque Linux ha evolucionado muchísimo y hay que reconocer que ya casi no hace falta hacer uso de la Consola para ejecutar programas y tareas varias, pero también hay veces que gracias al uso de la Consola se puede solucionar pequeños problema que de otra forma seria bastante mas complicado. En esos casos CliCompanion nos hecha una mano añadiendo una lista con diferentes comandos junto a nuestro terminal. La lista de los comando no es infinita, viene con unos cuantos; para cada comando hay una referencia donde se explica la función, también es posible añadir comandos y los parámetros correspondientes. Además CliCompanion tiene un apartado de búsqueda donde es posible encontrar el comando que mas nos interese en cada momento. Desde cuando lo instalé en mi Kubuntu 10.04, tengo que confirmar que es una muy buena aplicación y puede ser instalada con lo repositorios correspondientes y tener futuras actualizaciones o directamente através el paquete .DEB.
