Share Internet between Ubuntu and VmWare Windows

On my Ubuntu 9.10 I use Vmware Server 1.09, I use that 'NAT' setting under the Ethernet option in the virtual machine settings. That means that the guest operating system uses the same IP address etc as the host.
It's working.

Checking Disk Space From Gnome and Ubuntu

Disk Usage Analyzer is a graphical menu driven application that reports disk usage in Gnome and Ubuntu environments. DUA can scan the entire file system tree or individual directories, either local or remote. DUA is also dynamic, in that it will report in real time any devices that are mounted and unmounted.

To access Disk Usage Analyzer in Gnome, click on Applications \ Accessories \ Disk Usage Analyzer

When launched, DUA will start up in a stand by state, showing you total system capacity, used and available disk space.

To view the entire file system including usage by individual directories, click the Scan Filesystem icon on the toolbar. When the scan is completed, the full tree of your file system will be displayed.

From this display, you get a nice picture of the disk usage on the entire file system. You can also expand the top level directories and drill down to see sub-directoires and their disk usage, and sort each column to view each directory usage, size and contents. In the right window pane, a graphical layout is displayed. Moving your mouse over a block will display the directory and size.

Selecting Edit \ Preferences from the menu, allows selection of any additional devices connected to your Computer that can be enabled or disabled from being monitored.

A feature that I like with Disk Usage Analyzer, is the ability to right click and open the directory by launching Nautilus File Browser.

Checking Disk Space From The Command Line

Another way to view disk usage in Ubuntu is from the Terminal window by clicking on

Application \ Accessories \ Terminal from the panel in Gnome.

Unlike Windows, finding available disk space, from the command prompt, is much easier in Ubuntu using the df command when connected locally or remote via an SSH session.

DF command reports how much free disk space is available for each mount you have. When executing

DF, I like to use the -h option, which returns the output in a more readable format:

greg@lt1:~$ df -h

Filesystem Size Used Avail Use% Mounted on
/dev/sda5 116G 61G 50G 56% /
tmpfs 1.5G 0 1.5G 0% /lib/init/rw
varrun 1.5G 148K 1.5G 1% /var/run
varlock 1.5G 4.0K 1.5G 1% /var/lock
udev 1.5G 176K 1.5G 1% /dev
tmpfs 1.5G 412K 1.5G 1% /dev/shm
lrm 1.5G 2.2M 1.5G 1% /lib/modules/2.6.28-15-generic/volatile/dev/mapper/truecrypt1

DF can also report free disk space for individual directories by entering the following command at the prompt:

ds -h /nameofdirectory

Using df at the command prompt is most usefull when checking disk space on remote computers.

To view more available options with df, enter df –help at the command prompt.
