How to Add Swap Space

21 08 2010

You can either use a dedicated hard drive partition to add new swap space, or create a swap file on an existing filesystem and use it as swap space.

How much swap space is currently used by the system?

Free command displays the swap space. free -k shows the output in KB.

# free -k
             total       used       free     shared    buffers     cached
Mem:       3082356    2043700    1038656          0      50976    1646268
-/+ buffers/cache:     346456    2735900
Swap:      4192956          0    4192956

Swapon command with option -s, displays the current swap space in KB.

# swapon -s
Filename                        Type            Size    Used    Priority
/dev/sda2                       partition       4192956 0       -1

Swapon -s, is same as the following.

# cat /proc/swaps
Filename                        Type            Size    Used    Priority
/dev/sda2                       partition       4192956 0       -1

Method 1: Use a Hard Drive Partition for Additional Swap Space

If you have an additional hard disk, (or space available in an existing disk), create a partition using fdisk command. Let us assume that this partition is called /dev/sdc1

Now setup this newly created partition as swap area using the mkswap command as shown below.

# mkswap /dev/sdc1

Enable the swap partition for usage using swapon command as shown below.

# swapon /dev/sdc1

To make this swap space partition available even after the reboot, add the following line to the /etc/fstab file.

# cat /etc/fstab
/dev/sdc1               swap                    swap    defaults        0 0

Verify whether the newly created swap area is available for your use.

# swapon -s
Filename                        Type            Size    Used    Priority
/dev/sda2                       partition       4192956 0       -1
/dev/sdc1                       partition       1048568 0       -2

# free -k
             total       used       free     shared    buffers     cached
Mem:       3082356    3022364      59992          0      52056    2646472
-/+ buffers/cache:     323836    2758520
Swap:      5241524          0    5241524

Note: In the output of swapon -s command, the Type column will say “partition” if the swap space is created from a disk partition.

Method 2: Use a File for Additional Swap Space

If you don’t have any additional disks, you can create a file somewhere on your filesystem, and use that file for swap space.

The following dd command example creates a swap file with the name “myswapfile” under /root directory with a size of 1024MB (1GB).

# dd if=/dev/zero of=/root/myswapfile bs=1M count=1024
1024+0 records in
1024+0 records out

# ls -l /root/myswapfile
-rw-r--r--    1 root     root     1073741824 Aug 14 23:47 /root/myswapfile

Change the permission of the swap file so that only root can access it.

# chmod 600 /root/myswapfile

Make this file as a swap file using mkswap command.

# mkswap /root/myswapfile
Setting up swapspace version 1, size = 1073737 kB

Enable the newly created swapfile.

# swapon /root/myswapfile

To make this swap file available as a swap area even after the reboot, add the following line to the /etc/fstab file.

# cat /etc/fstab
/root/myswapfile               swap                    swap    defaults        0 0

Verify whether the newly created swap area is available for your use.

# swapon -s
Filename                        Type            Size    Used    Priority
/dev/sda2                       partition       4192956 0       -1
/root/myswapfile                file            1048568 0       -2

# free -k
             total       used       free     shared    buffers     cached
Mem:       3082356    3022364      59992          0      52056    2646472
-/+ buffers/cache:     323836    2758520
Swap:      5241524          0    5241524

Note: In the output of swapon -s command, the Type column will say “file” if the swap space is created from a swap file.

If you don’t want to reboot to verify whether the system takes all the swap space mentioned in the /etc/fstab, you can do the following, which will disable and enable all the swap partition mentioned in the /etc/fstab

# swapoff -a

# swapon -a

How to install Google video Chat in linux

21 08 2010

The Video chat feature for GMail in Linux is currently supported only on Ubuntu and Debian based systems. (RPM releases to come soon).

1. As with Windows and Mac, you have to download a Linux compatible plugin for GMail videochat. You can either download the Linux Plugin for GMail Videochat from the Videochat page or download it directly from this link. [.DEB File, 5.6 MB Download].

2. After the download is over, you can double click the .DEB file you just downloaded to start the Package Manager and install the plugin.

3. The Installation requires a dependency: libglew 1.5. But you need not worry as your Ubuntu / Debian package manager will handle it for you.

4. After the installation is over, make sure you restart your Browser for the settings and new changes to take effect. Bingo! you can now start Video chatting with you friends right away from  Linux too :-)

Clone a partition of Hard Drive Using an Ubuntu Live CD

11 06 2010

Whether you’re setting up multiple computers or doing a full backup, cloning hard drives is a common maintenance task. Don’t bother burning a new boot CD or paying for new software – you can do it easily with your Ubuntu Live CD.

Not only can you do this with your Ubuntu Live CD, you can do it right out of the box – no additional software needed! The program we’ll use is called dd, and it’s included with pretty much all Linux distributions. dd is a utility used to do low-level copying – rather than working with files, it works directly on the raw data on a storage device.

Note: dd gets a bad rap, because like many other Linux utilities, if misused it can be very destructive. If you’re not sure what you’re doing, you can easily wipe out an entire hard drive, in an unrecoverable way.

Of course, the flip side of that is that dd is extremely powerful, and can do very complex tasks with little user effort. If you’re careful, and follow these instructions closely, you can clone your hard drive with one command.

We’re going to take a small hard drive that we’ve been using and copy it to a new hard drive, which hasn’t been formatted yet.

To make sure that we’re working with the right drives, we’ll open up a terminal (Applications > Accessories > Terminal) and enter in the following command

sudo fdisk –l

We have two small drives, /dev/sda, which has two partitions, and /dev/sdc, which is completely unformatted. We want to copy the data from /dev/sda to /dev/sdc.

Note: while you can copy a smaller drive to a larger one, you can’t copy a larger drive to a smaller one with the method described below.

Now the fun part: using dd. The invocation we’ll use is:

sudo dd if=/dev/sda of=/dev/sdc

In this case, we’re telling dd that the input file (“if”) is /dev/sda, and the output file (“of”) is /dev/sdc. If your drives are quite large, this can take some time, but in our case it took just less than a minute.

If we do sudo fdisk –l again, we can see that, despite not formatting /dev/sdc at all, it now has the same partitions as /dev/sda.


Additionally, if we mount all of the partitions, we can see that all of the data on /dev/sdc is now the same as on /dev/sda.

Note: you may have to restart your computer to be able to mount the newly cloned drive.

And that’s it…If you exercise caution and make sure that you’re using the right drives as the input file and output file, dd isn’t anything to be scared of. Unlike other utilities, dd copies absolutely everything from one drive to another – that means that you can even recover files deleted from the original drive in the clone!

How to change the location of close button from left side to right side?

1 05 2010

In Ubuntu 10.04, the close button is on the LEFT side! How do you change that? We’re much more used to the button on the right side. I just upgraded from 9.10.

To move all the buttons back to the right hand side, run the following in a terminal:

gconftool-2 –set “/apps/metacity/general/button_layout” –type string “menu:minimize,maximize,close”

To it via GUI,

Gnome provides the means to your end with gconf-editor.

Use ALT-F2 to bring up the Run Application window, enter gconf-editor and click Run. Browse to apps > metacity > general and find the button_layout field.

You can use any combination of six values: : (colon), menu, minimize, maximize, spacer, and close. Button names need to be separated with commas. The colon denotes the separation between the left and right corners. Following are some examples.

The default Lucid layout.

The previous layout that we’ve been familiar with looks broken as the minimize button is designed to be sandwiched between the maximize and close buttons.

Here’s the previous look with Lucid’s button order.

A spacer can be added. Although it too slightly breaks the design, it may still be helpful to keep the close button separated slightly from the others. The menu button has been removed in the following example.

One alternate layout is to keep the minimize and maximize buttons to the left and pushing the close button to the right.

With gconf-editor, you can find whatever combination you’re most comfortable with. You can also use the command line tool gconftool-2 to set the value of the layout quickly. To get the pre-Lucid layout:

gconftool-2 --set /apps/metacity/general/button_layout --type=string :minimize,maximize,close
