HowTo: Wake Up Computers Using Linux Command [ Wake-on-LAN ( WOL ) ]

Posted on in Categories Debian Linux, Linux, Networking, Ubuntu Linux last updated April 3, 2012

Wake-on-LAN (WOL) is an Ethernet networking standard that allows a server to be turned on by a network message. You need to send ‘magic packets’ to wake-on-lan enabled ethernet adapters and motherboards, in order to switch on the called systems. Make sure you connect the NIC (eth0 or eth1) with the motherboard, and enable the WOL function in the BIOS. This is a quick guide to enable WOL under RHEL / Fedora / CentOS / Debian / Ubuntu Linux.

However, each and every month visitors are switching to Firefox or Google browser and so on. So I would like to know your reasons for making switch from IE to another browser. Why did you switch and which browser did you switch to?

Woman Blames Dell and Ubuntu For Missing Online School Classes

Posted on in Categories GNU/Open source, Linux, Linux desktop, Ubuntu Linux, Windows, windows vista last updated January 15, 2009

Another clueless woman has claimed that Dell computer and Ubuntu Linux have kept her from going back to school via online classes. According to a story – a woman bought a Dell computer and realized she ordered it with the Ubuntu Operating System rather than MS-Windows. She tried to change OS to Windows but Dell refused. Her Verizon High-Speed Internet CD won’t load, so she can’t access the internet. She also can’t install Microsoft Word, which she says is a requirement for MATC’s online classes. As a result, with no internet and no Microsoft Word, Schubert dropped out of MATC’s fall and spring semesters. The full story is here including followup.

Now, I’ve no idea about Verizon’s modem and DSL connection but most A/DSL provider modem (router) comes with an Ethernet port. There is no need to use wizard or CD based installer. Other software such as MS-Word can be replaced with OO (I submitted all my school work using OO office writer and no one noticed the difference… ). Further both Verizon and MATC ready to help:

Verizon says it will dispatch a technician to try to assist her accessing the internet without using the Windows-only installation disk.

MATC also says it promises to accept any of Schubert’s papers or class documents using whatever software she has installed.

So what is the problem here?

Find and Control All Hidden Running Services on MS Windows Server 2003 / Vista / XP System

Posted on in Categories News last updated January 13, 2010

Under Linux / UNIX it is very easy to find out all running services and shutdown unwanted services. All you have to do it go through the following directories or configuration files:
=> /etc/init.d/
=> /etc/rcX.d/
=> /etc/xinetd./d
=> /etc/inetd.conf
=> /usr/local/etc/rc.d

You can also use tools such as CentOS / RHEL ntsysv tool / Debian / Ubuntu service configuration tool. Ultimately, netstat command always displays a list of all open ports:
# netstat -tulpn

Controlling Services under MS Windows Server

Shutting down services under Windows Vista or Server 2003 is not straightforward. Microsoft allows different ways to start an application at system startup or user login which results into a true messy system. MSConfig utility bundled with Windows Me and XP does a good job but it is not sufficient. There is a nice utility called Autorun:

This utility, which has the most comprehensive knowledge of auto-starting locations of any startup monitor, shows you what programs are configured to run during system bootup or login, and shows you the entries in the order Windows processes them. These programs include ones in your startup folder, Run, RunOnce, and other Registry keys. You can configure Autoruns to show other locations, including Explorer shell extensions, toolbars, browser helper objects, Winlogon notifications, auto-start services, and much more. Autoruns goes way beyond the MSConfig utility bundled with Windows Me and XP.

Autoruns’ Hide Signed Microsoft Entries option helps you to zoom in on third-party auto-starting images that have been added to your system and it has support for looking at the auto-starting images configured for other accounts configured on a system. Also included in the download package is a command-line equivalent that can output in CSV format, Autorunsc.

Use autoruns utility to manage all startup programs under Windows. You’ll probably be surprised at how many executables are launched automatically!
