Buffalo High Power Routers with Linux Based Firmware For Large Home Network

blogger /

Buffalo WZR-HP-G300N & WHR-HP-G300N are high power routers and access points. The routers are powered by wireless n technology with DD-WRT Linux based open source firmware – ideal solutions for high-speed and large homes network coverage.

Should you build a wireless network environment for your large home for heavy duty applications such as streaming video and gaming, you need to search high performance wireless routers in delivering high speed and longer distance coverage. For heavy duty tasks, your router should be powered by the latest wireless technology for high-speed and longer distance coverage. The router should also include the Quality of Service feature to prioritize the video and gaming traffic.

Generally the high performance and high power routers are more expensive than ordinary home routers. Should your budget is limited; consider affordable high-performance routers: Buffalo WZR-HP-G300N & WHR-HP-G300N wireless routers.

Why Buffalo WZR-HP-G300N & WHR-HP-G300N?

Unlike high performance home wireless routers, the WZR-HP-G300N & WHR-HP-G300N are embedded with DD-WRT which means the routers are based on Open Source Linux firmware. DD-WRT is a Linux based alternative Open-Source firmware suitable for many types of wireless routers and other embedded systems for providing the easiest handling even by non-technicians, high-speed, and reliable and supporting a large numbers of functionalities to fulfill the demand of professionals.

Both routers are powered by the latest wireless 802.11n technology – the fastest wireless technology available in the marketplace. The routers can deliver high-speeds of up to 300Mbps in ideal conditions (the actual speeds may vary). The routers are powered by with the High-Power technology for extended wireless coverage and performance which are ideal for internet gaming and watching videos.

Now which one is suitable for your need? As general both wireless routers have the same features for high power wireless network environment but the WZR-HP-G300N is designed for heavy duty gaming and streaming HD media contents. The following are the main different between the two routers. Interfaces

The WHR-HP-G300N routers are equipped with the 10/100 Mbps Ethernet ports but the WZR-HP-G300N routers are Gigabit Ethernet ports both for LAN (4xports) and WAN (1xport) interfaces. You can use the Gigabit ports for high-bandwidth applications such as video and large bulk of files transfer. Should you require high speed wired connection, the WZR-HP-G300N is your router.

Another value for WZR-HP-G300N is the USB port with AirShare technology to allow you share the external USB storage across the network and even you can access it remotely. When you upgrade the more advanced firmware, it will support BitTorent capability.

Unfortunately, you can not attach a USB printer to the USB port for sharing. Should you need to share the printer, you need to buy separate print-server or wireless print-server, unless you need to configure the printer attached to one of your computer and share it across the network. Or if your printer is embedded with the Ethernet print-server, you can connect it to one of the router’s Ethernet LAN port and configure it for sharing. To provide higher power signal you can upgrade the external antenna with the high-gain directional antenna, but this apply only for WHR-HP-G300N.

Secure guest access is only available on WZR. With secure guest access, you can provide separate internet access to your friends without compromising your internal network. For small offices deployment this feature is very important. You create separate security boundary for your visitors who need internet access with their laptops when they visit your office.

Alternative solution when you need to share the printer and the external storage across the network – you can consider Trendnet TEW-673GRU. This router includes two USB ports to allow you share a USB printer and an external USB storage at the same time.

Best Beginners Linux Commands

There are many common Linux commands that will be to your benefit, if you ever even use your command line software in Linux. Many average users just use the graphical user interface instead which usually provides many tools and front-ends to Linux common commands. This Linux system tutorial on control commands will help the average user in the event X server accidents, fails, is not properly designed, etc. So stay with me for some of the more prevalent Linux bash instructions.
Some of the more Best free Linux tutorials. A Linux system Unix shell commands tend to be listed below for more information on each command you can always manage man [command] and this will bring up the manage for that command, you can also click on the requires listed for some frequent examples and format.
First before I list them virtually any syntax in [] will be needing some kind of input of your stuff normally, for example:
guy [command] you will want to actually change [command] with the shell order you want to read the guy page for: gentleman ls will give you the man page for the Linux covering command ls.
linux ls command is used to list files on the filesystem.
File command that will check the filetype, this will output to you what the file type is no matter what the extension is.
Mkdir command used to make directories on the filesystem.
cd is used for changing into a different directory in the Linux shell
cp is the Linux copy command, this shell command is used to copy files|directories from one location on the filesystem to another.
Mv the Linux terminal command to move files|directories. Like the cp command, but deletes the original source.
rm shell command in Linux to remove files|directories.
Linux cat command- this command is used to print|view the contents of a file to the screen|terminal.
Grep command used to search|find contents of a file and print|view on your terminal|screen.
Linux more and less commands that will allow you to read output of files, unlike cat that will output the entire file at once, even if it is too large for your terminal more and less will output only as many lines as the shell you are in can output, and allow you to scroll through the file contents.
Chown Linux command to change ownership of a file|directory.
Linux chmod command that allows you to change mode of user access|permissions, basically set read, write, and execute permissions.
Linux ps lists the current running processes on your Linux system
Linux kill and killall commands used to kill|terminate running processes

Importance Of Linux Knowledge In Present Interview Method Of Many Multi-national Companies

blogger /

Linux plays a major role in many technical interview around the world for every kind of job.Interview questions play an important role for students in college life and we know the importance of interviews which will be the starting point in your career. Many students will fear to face interview in the beginning stage but they will be used to it when they gain some experience by attending it frequently which will help them to gain experience. So it is a better practice of attending mock interviews before they attend real interviews. And it is also a good practice to read frequently asked interview questions so that you can be prepared to answers those questions when asked in original interviews and get selected easily in top mnc companies.

When we consider engineering groups, linux interview question plays an important role in every department which is the back-bone of computer engineering.Linux is a operating system which should be known by technical guys and with the development of linux,it gave way to shell scripting language.So linux plays a important role in computer technology even if many advanced systems has been found. Usually linux will be thought in school days through which students will try to show interest to explore and master linux as soon as possible. Many books are also available to master it but when we consider for job interview ,the amount of preparation for it will be very less due to lack of time to cover all technical stuffs before we attend the interview So as a blogger I posted easy and complex linux interview questions with answers in my blog Linux Interview Questions with answers which contain questions related to shell scripting and so on.All questions and answers discussed in my blog are verified from my teachers and so my sincere advice is too read those questions at high priority and I guarantee that hr of different companies will mostly concentrate on the questions that are given in that site so this would be a easier way to impress Hr without any trouble. So its a better practice of reading these kind of blogs rather than reading the entire book before attending an interview. I hope you will like my work in it and pass this valuable information to your friends who is need of it.Kindly post your comments in my blog so that I can improve my blog further.

Automatic Installs Of Turnkey Linux Appliances On Virtual Private Servers

blogger /

Or How to set up a fully working Joomla, Drupal, LAMP, LAPP, Zimbra, Torrent server etc., in a couple of minutes)

Turnkey Linux comprises a set of free, Ubuntu-based software appliances that are primarily available for server-type usage scenarios, such as setting up database, web, forum, wiki and photo gallery servers. Each appliance is preconfigured to work out of the box, with ease of use being the primary goal behind the Turnkey Linux project.

This is extremely useful in itself, but if you wanted to experiment with these appliances, potentially to evaluate or otherwise test them, it would be great if you could perform installations with the absolute minimum of effort.

Using Turnkey Linux on Virtual Private Servers

A number of hosting providers, including GigaTux and GPLHost, provide Linux VPS services, which usually enable users to have their own virtual server with automatic provisioning of major Linux distributions, such as Debian, Ubuntu or CentOS. Work has been performed by GigaTux in conjunction with the Turnkey Linux team and has managed to take the automatic installation concept one step further to enable this to work with all Turnkey Linux appliances. This is made possible by using frameworks provided by the excellent server open source control panel, DTC.

Turnkey Linux appliances enable users to easily deploy primarily web-based applications within an entire Linux kernel and Ubuntu-based package set. Once a distribution is chosen within the control panel, the install is fully completed within a few minutes and ready to be customised. This enables a rapid deployment of a tested setup, with full update and security support provided by the Turnkey Linux and Ubuntu package maintainers.

Our efforts are available to all using the DTC control panel, with Debian packages for Lenny being provided. Additionally, scripts have been written such that when new or updated appliances are released, new deployable packages for the DTC control panel are created and made available in our repository automatically.

Technical Script Details

It is not actually too difficult to configure images to work for automatic deployment, but performing this manually for every appliance is a time consuming process. The scripts we have written will automatically perform the following steps for each appliance:

Create a new directory with a name similar to the actual release version, e.g. turnkey-core-2009.02-hardy-x86.

Copy across common template files. These include the following:

custom_os: Customises each appliance by configuring basic networking, spawning gettys on the right devices and setting a customised MOTD with the VPS number and hostname.

install_os: Custom instructions to install this appliance, which essentially involves untaring the provided image into the VPS.

setup_network: Custom instructions called when setting up the network. Because Turnkey Linux uses resolveconf for DNS configuration, this reads information from /etc/resolv.conf from the dom0 (this is designed for use with Xen) and copies it to /etc/network/interfaces in the domU.

debian/*: These are the files changelog, control, compat, copyright, files, install and rules which are required to create a.deb packages. These have substitution variables (e.g. for the package name) which are overwritten by our script.

Copy the preinstalled image (a.tar.bz2 file).

Tailor the template files (as above).

Invoke dpkg-buildpackage in this directory to create the actual.deb file.

Call reprepro, a tool we use to manage Debian repository directory structures, to remove old versions of this appliance and add the new one.

It’s as simple as that. If you are interested, the raw scripts are downloadable. They will need some customisation for your setup as there are hard coded directories in there.

I want to play with one!

If you are happy playing with just one appliance, you can of course just download it from the Turnkey Linux website and install it on your PC (or use a Virtualisation solution like Xen or VMWare).

However, if you want to rapidly try out a variety of appliances using the setup we have made, the quickest way would be to rent a VPS. Alternately, you can install the DTC control panel yourself and add our Debian repository to your /etc/apt/sources.list. This setup requires you to run a fully featured Xen setup and requires significant configuration.
