IPv6 benefits - IPv6 has longer adresses than IPv4 — 128 bits (16 bytes), instead of 32 bits (4 bytes) — and thus provides a huge supply of Internet addresses
- A simplified header of seven fields versus 13 in IPv4 to allow routers to process packets faster
- Improved options with the new header, thus routers get another speedup with skipping options not intended for them
- Better security with improvements in authentication and privacy (Not much difference while retrofitted to IPv4).
- full QOS (quality of service) - the sense of urgency is greater

Although Joomla is one of the most advance CMS available, there are some things that I really don’t like/agree with. One of these things is the complex Access Control List. There are too many different user types and registered users have no permission to add content to the site. They need to be upgraded from "Registered" to "Author". Still, and Author can only create content, but not publish it. Only a Publisher can publish content. And between Author and Publisher there is still the Editor, that can create and edit content, but can’t publish. As you can see, there are too many different user types (and I forgot to mention the Manager and Administrator types also availabel for the frontend. On the backend, another long list exhists). |

This is a practical selection of the commands we use most often. Press <Tab> to see the listing of all available command (on your PATH).

Many of these "commands" can be accessed from your favourite GUI front-end (probably KDE or Gnome) by clicking on the right menu or button. They can all be run from the command line. Programs that require GUI have to be run from a terminal opened under a GUI. |

Two of the fundamental aspects of Linux system security and troubleshooting are knowing what services are running, and what connections and services are available. We're all familiar with ps for viewing active services. netstat goes a couple of steps further, and displays all available connections, services, and their status. It shows one type of service that ps does not: services run from inetd or xinetd, because inetd/xinetd start them up on demand. If the service is available but not active, such as telnet, all you see in ps is either inetd or xinetd: |
