iptables -L -t nat

-L, –list [chain]
List all rules in the selected chain.  If no chain is selected, all chains are listed. Like every other iptables command, it applies to the
specified table (filter is the default), so NAT rules get listed by

This  option  specifies  the  packet matching table which the command should operate on.

dmidecode: Finding Out Hardware Details

December 11th, 2011

Dmidecode reports information about your system’s hardware as described in your system BIOS according to the SMBIOS/DMI standard.
This information typically includes system manufacturer, model name, serial number, BIOS version, asset tag as well as a lot of other details of varying level of interest and reliability depending on the manufacturer.
This will often include usage status for the CPU sockets, expansion slots (e.g. AGP, PCI, ISA) and memory module slots, and the list of I/O ports (e.g. serial, parallel, USB).

Beware that DMI data have proven to be too unreliable to be blindly trusted. Dmidecode does not scan your hardware, it only reports what the BIOS told it to.

Default theme CSS files and their purposes

November 13th, 2011

Default theme CSS files and their purposes

application.css :-
application.css Contains default styling having to do with components of applications. This includes the tabs, expandable trees, dialog overlays, and the results grid (that is, search container). Much of the markup for these styles is created by Liferay’s tag libraries.
base.css :-
base.css Contains default styling for standard HTML tags, such as paragraphs, headings,tables, and more. This file also contains styling for some Liferay-specific page elements, such as errors, warnings, tooltips, the loading animation, and more.
dockbar.css :-
dockbar.css Contains default styling for the Dockbar, which floats at the top of the page when a user is logged in.
custom.css :-
custom.css A blank file that is loaded last. As a best practice, theme developers should put their custom styles here to override default styles provided by Liferay in the other theme  CSS files.
forms.css :-
forms.css Contains default styling for all form elements.
layout.css :-
layout.css Contains default styling used by layout templates.
main.css :-
main.css Contains no styling, but imports the rest of the files.
navigation.css :-
navigation.css Contains default styling for the main navigation elements.
portlet.css :-
portlet.css Contains default styling for the portlet windows.
