tutorial - How to Backup your Blogger Blog Online for Free?

Yes, you can now Backup your Blog hosted on Blogger for free.

BlogBackupr is an online application that only needs a URL to create the full backing of any blog using feeds. It does not require a lengthy registration but needs your e-mail address so that you have access to a panel where you can see your backups. You can download back the backups in three formats (xml, txt and html), and even restore your blog if you have any problems.

The restoration feature works fine for Wordpress blogs and surprisingly also for blogs on Blogger. Well, I guess the restoration for Blogger is a novelty and is also a unique feature, that I know of that lets you do it automatically.

It's a great tool for blogs that do not provide a system backup / restore themselves.

tutorial - MythBusters - Switch to a Linux-based OS such as Ubuntu.

Computer operating systems loaded with stuff I don't want and will never use.

In the tech world this phenomenon is known as “software bloat” or “feature bloat.” It's a well-documented problem and a frequent complaint about Windows OSs—Vista in particular. In addition to being buggy, the extra features tend to bog down your system by demanding more processing power and memory. Computer-makers: Don't load up operating systems with features and then make us sweat to figure out how to get rid of the fat.

Most features can be set up as options. Why not start with a computer loaded with basic stuff that works 100 percent of the time? Then, give us the option of adding the bells and whistles. There's another solution available to consumers: Switch to a Linux-based OS such as Ubuntu. Since most Linux OSs are free, there's no business reason to bloat up the system with feature frills.

tutorial - Duplicating a disk

If you have two IDE drives that are of identical size, and provided that you are sure they contain no bad sectors and provided neither are mounted, you can run

dd if=/dev/hdc of=/dev/hdd

to copy the entire disk and avoid having to install an operating system from scratch. It doesn't matter what is on the original (Windows, LINUX, or whatever) since each sector is identically duplicated; the new system will work perfectly.

tutorial - Relative vs. Absolute Pathnames

Commands can be given file name arguments in two ways. If you are in the same directory as the file (i.e., the file is in the current directory), then you can just enter the file name on its own (e.g., cp my_file new_file). Otherwise, you can enter the full path name, like cp /home/jack/my_file /home/jack/new_file.

Very often administrators use the notation ./my_file to be clear about the distinction, for instance, cp ./my_file ./new_file. The leading ./ makes it clear that both files are relative to the current directory. File names not starting with a / are called relative path names, and otherwise, absolute path names.

tutorial - mkswap, swapon, and swapoff

The mkswap command formats a partition to be used as a swap device. For our disk,

mkswap -c /dev/hda5

-c has the same meaning to check for bad blocks.

Once the partition is formatted, the kernel can be signalled to use that partition as a swap partition with

swapon /dev/hda5

and to stop usage,

swapoff /dev/hda5

You Can have as many of them as you like. You can swapon many different partitions simultaneously.

tutorial - Limiting large requests in apache

Apache has several directives that allow you to limit the size of a request, this can also be useful for mitigating the effects of a denial of service attack.

A good place to start is the LimitRequestBody directive. This directive is set to unlimited by default. If you are allowing file uploads of no larger than 1MB, you could set this setting to something like:

LimitRequestBody 1048576

If you're not allowing file uploads you can set it even smaller.

Some other directives to look at are LimitRequestFields, LimitRequestFieldSize and LimitRequestLine. These directives are set to a reasonable defaults for most servers, but you may want to tweak them to best fit your needs. See the documentation for more info.

tutorial - HowTo boot the system into Resuce/Single-User or Emergency Mode

Booting into Rescue Mode

Rescue mode provides the ability to boot a small Linux environment entirely from CD-ROM, or some other boot method, instead of the system's hard drive.

As the name implies, rescue mode is provided to rescue you from something. During normal operation, your Linux system uses files located on your system's hard drive to do everything — run programs, store your files, and more.

Once you have booted using bootable disk, add the keyword rescue as a kernel parameter.

linux rescue

Booting into Single-User Mode

One of the advantages of single-user mode is that you do not need a boot CD-ROM; however, it does not give you the option to mount the file systems as read-only or not mount them at all.

In single-user mode, your computer boots to runlevel 1. Your local file systems are mounted, but your network is not activated.

use the following steps to boot into single-user mode:

1.At the GRUB splash screen at boot time, press any key to enter the GRUB interactive menu.
2.Select Linux with the version of the kernel that you wish to boot and type a to append the line.
3.Go to the end of the line and type single as a separate word (press the Spacebar and then type single). Press Enter to exit edit mode.

Emergency Mode

In emergency mode, you are booted into the most minimal environment possible. The root file system is mounted read-only and almost nothing is set up. The main advantage of emergency mode over single-user mode is that the init files are not loaded. If init is corrupted or not working, you can still mount file systems to recover data that could be lost during a re-installation.

To boot into emergency mode, use the same method as described for single-user mode, with one exception, replace the keyword single with the keyword emergency.

tutorial - HowTo make Installation Boot CD-ROM (RedHat)

isolinux is used for booting the Red Hat. To create your own CD-ROM to boot the installation program, use the following instructions:

Copy the isolinux/ directory from the Red Hat Enterprise Linux DVD or CD #1 into a temporary directory

cp -r /isolinux/

Change directories to the directory you have created:

cd

Make sure the files you have copied have appropriate permissions:

chmod u+w isolinux/*

Finally, issue the following command to create the ISO image file:

mkisofs -o file.iso -b isolinux.bin -c boot.cat -no-emul-boot \ -boot-load-size 4 -boot-info-table -R -J -v -T isolinux/

Burn the resulting ISO image (named file.iso and located in ) to a CD-ROM as you normally would.

tutorial - HowTo execute the program during Linux startup

The /etc/rc.d/rc.local script is executed by the init command at boot time or when changing runlevels. Adding commands to the bottom of this script is an easy way to perform necessary tasks like starting special services or initialize devices without writing complex initialization scripts in the /etc/rc.d/init.d/ directory and creating symbolic links.

tutorial - HowTo Resize a Partition

Before resizing a partition, boot into rescue mode. Read this for booting into rescue mode.

Start parted, where /dev/sda is the device on which to resize the partition:

parted /dev/sda

View the current partition table to determine the minor number of the partition to resize as well as the start and end points for the partition:

print

To resize the partition, use the resize command followed by the minor number for the partition, the starting place in megabytes, and the end place in megabytes. For example:

resize 3 1024 2048

After resizing the partition, use the print command to confirm that the partition has been resized correctly, is the correct partition type, and is the correct file system type.

After rebooting the system into normal mode, use the command df to make sure the partition was mounted and is recognized with the new size.

tutorial - HowTo get the firstboot screen again in Fedora/RedHat

The first time the system boots, the /sbin/init program calls the /etc/rc.d/init.d/firstboot script, which in turn launches the Setup Agent. This application allows the user to install the latest updates as well as additional applications.

The /etc/sysconfig/firstboot file tells the Setup Agent application not to run on subsequent reboots. To run it the next time the system boots, remove /etc/sysconfig/firstboot and execute

chkconfig --level 5 firstboot on.

tutorial - HowTo Verifying Signature of RPM Packages

To check the GnuPG signature of an RPM file after importing the builder's GnuPG key, use the following command (replace with the filename of the RPM package):

rpm -K

If all goes well, the following message is displayed: md5 gpg OK. This means that the signature of the package has been verified, and that it is not corrupt.

tutorial - USB drivers going GPL-only in kernel 2.6.25

USB drivers for Linux will be GPL-only with the release of the upcoming kernel 2.6.25.. USB maintainer Greg Kroah-Hartman writes:

"Over two years ago, the Linux USB developers stated that they believed there was no way to create a USB kernel driver that was not under the GPL. This patch moves the USB apis to enforce that decision."

So, Just wait for 2.6.25 kernel release from kernel.org,
Apply the patch or compile the new one to have a full support for your USB systems.

tutorial - HowTo Password Protect the GRUB

The main reason to password protect the GRUB boot loder is to Prevent Access to Single User Mode — If attackers can boot the system into single user mode, they are logged in automatically as root without being prompted for the root password.

To do this, open a shell prompt, log in as root, and type:

/sbin/grub-md5-crypt

When prompted, type the GRUB password and press Enter. This returns an MD5 hash of the password.

Next, edit the GRUB configuration file /boot/grub/grub.conf. Open the file and below the timeout line in the main section of the document, add the following line:

password --md5

Replace with the value returned by /sbin/grub-md5-crypt

tutorial - Is Linus is the real author of LINUX?

“A couple of years ago this guy called Ken Brown wrote a book saying that Linus stole Linux from me… It later came out that Microsoft had paid him to do this…”

–Andrew S Tanenbaum, father on MINIX

The Alexis de Tocqueville Institution released a report based on a forthcoming book by Ken Brown, "Samizdat: And Other Issues Regarding the 'Source' Of Open Source Code", which challenges the claim that Linus Torvalds write Linux.

Linus responded in a LinuxWorld interview with his typical sense of humour: "Ok, I admit it. I was just a front-man for the real fathers of Linux, the Tooth Fairy and Santa Claus." He also added that he is relieved that he can return to his chosen profession: "the exploration of the fascinating mating dance of the common newt."

The story which broke the news about the report states that "Brown's account is based on extensive interviews with more than two dozen leading technologists including Richard Stallman, Dennis Ritchie, and Andrew Tanenbaum." Newsforge, however, carried a story stating that "The greater part of Brown's sources are personal Web pages of people who are not considered experts in the field of Unix, Linux, GNU, or other related subjects, home pages of people who are considered experts but were speaking generally about the subject of the history of Unix, and quotes taken grossly out of context from interviews that Brown did not conduct or take part in."

Andrew Tanenbaum, however, was directly interviewed by Ken Brown. As soon as news about the report broke, Tanenbaum wrote to Slashdot to provide a link to a page on his website which details what exactly went on in this interview.

In this page, Tanenbaum says that he quickly became suspicious of Brown and his motives. Brown, he says, was evasive about his reasons for the interview, and would not reveal who was providing his funding (though Wired have speculated that Microsoft are one of AdTI's main sponsors). He also found that Brown knew nothing about the history of Unix. Later in the interview, Brown came to his reason for being there, asking questions like "Didn't he steal pieces of MINIX without permission?" Though Tanenbaum tried to explain the actual influence that Minix had on Linux, the Newsforge story says that much of the report relies on claims that Linux contains stolen Minix code.

Tanenbaum later provided another page, with the results of a code comparison Alexey Toptygin conducted for Brown, comparing Minix and early versions of Linux. The results are pretty clear: there were only four similar sections of code, one based on the ANSI C standard, two based on POSIX, and the last in the code to access the minix filesystem - code which must be similar to work.

This fresh accusation, on top of those already laid by SCO, has caused Linus to adopt new measures before accepting code into Linux: the Developer's Certificate of Origin, which requires that each contributor state that they are entitled to contribute their code.

tutorial - HowTo get information about your filesystem?

At times, you need some information about your file system. There is a utility dumpe2fs which can give you number of information about Linux file system. For example, if you want status of bad blocks on a device containing Linux file system, run dumpe2fs with option –b. It will check for bad blocks and give you information about the bad blocks it finds in a dumped file. Dumpe2fs has various arguments and options and you can get the information you need about your file system for a quick diagnosis. For more information on dumpe2fs, see its man pages.

tutorial - Network Configuration Files in RedHat and Fedora

The primary network configuration files are as follows:

/etc/hosts

It can also be used to resolve hostnames on small networks with no DNS server. For more information, refer to the hosts man page.

/etc/resolv.conf

This file specifies the IP addresses of DNS servers and the search domain. For more information about this file, refer to the resolv.conf man page.

/etc/sysconfig/network

This file specifies routing and host information for all network interfaces.

/etc/sysconfig/network-scripts/ifcfg-

For each network interface, there is a corresponding interface configuration script. Each of these files provide information specific to a particular network interface.

tutorial - HowTo Install GRUB

If GRUB was not installed during the installation process, it can be installed afterward. Once installed, it automatically becomes the default boot loader.

Before installing GRUB, make sure to use the latest GRUB package available or use the GRUB package from the installation CD-ROMs.

Once the GRUB package is installed, open a root shell prompt and run the command /sbin/grub-install , where is the location that the GRUB Stage 1 boot loader should be installed. For example, the following command installs GRUB to the MBR of the master IDE device on the primary IDE bus:

        /sbin/grub-install /dev/hda

The next time the system boots, the GRUB graphical boot loader menu appears before the kernel loads into memory.

source:http://linuxpoison.blogspot.com/2008/03/13578175802867.html

tutorial - Alternative Boot Loaders

If you do not wish to use a boot loader, you have several alternatives:

LOADLIN

You can load Linux from MS-DOS. Unfortunately, this requires a copy of the Linux kernel (and an initial RAM disk, if you have a SCSI adapter) to be available on an MS-DOS partition. The only way to accomplish this is to boot your Linux system using some other method (for example, from a boot CD-ROM) and then copy the kernel to an MS-DOS partition. LOADLIN is available from

ftp://metalab.unc.edu/pub/Linux/system/boot/dualboot/

and associated mirror sites.

SYSLINUX

SYSLINUX is an MS-DOS program very similar to LOADLIN. It is also available from

ftp://metalab.unc.edu/pub/Linux/system/boot/loaders/

and associated mirror sites.

Commercial boot loaders

You can load Linux using commercial boot loaders. For example, System Commander and Partition Magic are able to boot Linux (but still require GRUB to be installed in your Linux root partition).

tutorial - Run Linux on Windows seamlessly without virtualizers

andLinux is a complete Ubuntu Linux system running seamlessly in Windows 2000 based systems (2000, XP, 2003, Vista [32-bit only])

andLinux uses coLinux as its core which is confusing for many people. coLinux is a port of the Linux kernel to Windows. Although this technology is a bit like running Linux in a virtual machine, coLinux differs itself by being more of a merger of Windows and the Linux kernel and not an emulated PC, making it more efficient. Xming is used as X server and PulseAudio as sound server.

andLinux is not just for development and runs almost all Linux applications without modification.

tutorial - Boot Process Performance Visualization

Bootchart is a tool for performance analysis and visualization of the GNU/Linux boot process. Resource utilization and process information are collected during the boot process and are later rendered in a PNG, SVG or EPS encoded chart.

Bootchart provides a shell script to be run by the kernel in the init phase. The script will run in background and collect process information, CPU statistics and disk usage statistics from the /proc file system. The performance data are stored in memory and are written to disk once the boot process completes.

tutorial - Dell’s Ubuntu Linux PCs aren’t setting the world on fire

OK, so Dell’s desktop Linux PCs aren’t setting the world on fire. The PC giant has sold about 40,000 of the Ubuntu Linux PCs since introducing them at the end of July. That’s a run rate of about 8,000 per month. And one of those systems was sold to The VAR Guy. So what will Dell do next? End the Linux experiment based on slow sales? Guess again.

Instead of backing off its Ubuntu Linux commitment, Dell continues to see big promise in the technology. The company will likely certify its servers to run Ubuntu Linux. The VAR Guy first reported over the summer and again in October that Canonical — Ubuntu’s promoter — planned to make a small business server push sometime in late 2007 or 2008. Now, reports are circulating that Dell will jump on that bandwagon.

Smart move. There’s a void in the small business server market. Windows Small Business Server is too complex for some small businesses. And neither Red Hat nor Novell have effectively mobilized their businesses to fully unlock small business opportunities.

Canonical working with Dell provides a rather interesting market alternative. Plus, there are strong indications that Canonical’s small business server will involve LAMP (Linux, Apache, MySQL, PHP, etc.), the server stack that’s so freakin’ popular in large enterprises and universities.
