Few things stoke the emotions of computer fans like a good Mac-versus-PC smack down. Macs “could be” as vulnerable as Windows not are as vulnerable

as windows.

When you use a Macintosh, or indeed any Unix-based system, it’s comforting to know that your computer is more secure than Windows. It is, however, a mistake to equate “more secure” with “invulnerable.” Keep in mind that the hacker who does break into your system has more skills than the average script kiddy. And when this happens, what should you be looking for? Let’s assume that a malicious hacker wants one of two things:

1.To steal valuable data from your computer, such as credit card numbers or passwords.

2.Access to your system so that they can cover their tracks as they hack into other peoples computers.

In this article I attempted to fight for the Windows operating system, I feel like that article only strengthens my point that Mac’s are superior computer system. Why Apple is thought to be so secure is because virus writers would rather target the 90% of the population that have PCs rather than the 10% that are using Macs.

Some of the things that attracted me to a Mac are its looks, high memory capability and the stability in terms of security

The only thing in the article against Macs says that Macs “could soon be as vulnerable as Windows machines” not that they are already. Personally I think that “could soon” has a lot to do with the new ability to put Windows on them. OS X remains a secure operating system. Windows on the other hand is a security nightmare. The only way you’re going to have security problems on your Mac is if you feel like you have to put a crappy OS (Windows) on it.

It always traces back to Microsoft’s untenable policy of maintaining gaps in Windows security to avoid competing with 3rd party vendors and certified partners.

Apple’s taking a different approach: What users need is in the box: Anti-virus, anti-spam, encryption, image backup and restore, offsite safe storage through .Mac, and launched. Pretty soon any debate with Microsoft over security can be ended in one round when Apple stands up, says ‘launched’, and sits back down.”

If you think that your machine had been compromised there are tools you can use to scan your system for known root kits such as Root kit Hunter and chkrootkit. Root kit Hunter runs on OS X and chkrootkit does work on BSD-based systems, but not specifically OS X. These tools look for evidence of root kits by a variety of means, but are in part based around the idea of checking the size, permissions, and checksum of a known target file or program, such as ls, with a database of known good values.

With the user-friendly Linux distribution Ubuntu gaining popularity at an astounding rate, you may be considering making the move from Windows to Linux.

If you are, then you will have wondered how you will work and play without the applications and games you use every day in Windows.

Windows applications can be run in Linux, just not natively. You have two main options: Emulation and Virtualization. Neither are as effective as dual-booting but I will explain them here and their drawbacks.

Emulation allows you to run Windows applications through a “translation layer” which tricks the applications into thinking they are running on Windows. Although great advances have been made by the WINE Project and commercial offshoot, Cedega, many applications are still unsupported. Support for certain applications may even vary depending on your hardware configuration.

Virtualization takes running Windows applications on Linux a step further and is capable of running an entire Windows (or any other) operating system straight from your Linux desktop. With the free application VirtualBox, you can create a “virtual machine” and install any version of Windows you wish onto it.

A virtual machine is switched on and off exactly like a normal PC, except the entire operating system runs inside a window on your Linux desktop. You may then install any Windows applications you wish into the virtual machine and use them as you normally would.

Running applications natively in Windows, via a virtual machine, is far more reliable than running them through a translation layer, but virtualization has its drawbacks too.

When you run Windows in a virtual machine you are effectively running two operating systems, simultaneously, on one computer. This has obvious performance drawbacks. Although most office-type applications could be run this way, if your office insists on a particular piece of Windows-specific software, performance issues and lack of DirectX support severely hampers game applications.

The only way to successfully run all your Windows applications at their full capacity is to install Windows and Linux as dual-boot operating systems.

Dual-booting is the process of installing two operating systems side-by-side, to be run independently. By this method you will be presented with a menu listing your operating systems when you switch on your computer. this allows you to choose the OS most suitable for the tasks at hand, be it work or gaming.

I personally run Ubuntu 7.04 and Windows XP as a dual-boot system. I mostly use Ubuntu for day-to-day tasks and run Windows XP purely for gaming. This way, dual-booting grants me access to the best features of both operating systems and allows me to use my computer to its full potential.

Perfect Application to handle Real time scenarios

A real time operating system is based on the OS which has the capability

to perform a number of functions at a time. This RTOS only serves real-time applications. These real-time applications include robots, spaceships; research tools used by scientists and embedded systems like home appliances, cell phones and thermostat.

RTOS system captures the real time events and brings out the results which may slightly differ from the reality. It’s processing and computation totally depends on the way it is programmed. RTOS can be judged as how quickly it performs the operation and how accurate the results are. Most important factors which increase the working of this system are low interrupt latency and a low thread switching latency.

The real time operating system is designed keeping in mind every aspect in mind of real life. This operating system is designed on two basic principles. First design pattern is that it should focus on event-driven programming so that tasks can process depending upon their scheduling priorities. Second design refers to time sharing feature so to process tasks on the basis of clock interrupts.

In RTOS allocation of memory is the most critical task. Two elements are of significant importance in case of memory allocation. First one is speed and second is the fragmentation of free region during the memory allocation process.

Resource sharing is entangled in a multitasking system, when two processes are accessing the same resource at a time. This may bring some confusing results in the form of inconsistency, unreliability and data duplication. Some solutions are suggested by developers to solve this problem

1. By disabling interrupts

2. By the process of message passing; one user can stop its working while other is in progress.

3. Binary semaphore

The latest Microsoft Windows operating systems have a time synchronisation utility installed by default called ‘Windows Time’. The Windows

time service allows a Microsoft network to provide time synchronisation of machines in a domain. This article introduces how to configure the Microsoft Windows 2000 and 2003 operating systems to operate as a SNTPNTP Time Server. The article discusses how to change Windows registry entries to configure the Time Service.

Before modifying any Windows registry settings, it is a good idea to save the registry. In the even of any difficulties, the registry can be restored to its former state.

Windows 2000 Time Service

Windows 2000 has an integrated network time synchronization service, installed by default, which can be configured to synchronize to a Time Server. In fact, by changing associated registry settings, the service can act as both a time client and a time server to synchronize other network time clients.

The Windows Time service should be present in the systems service list. The application executable is ‘w32time.exe’. The parameter list for time service should be present in the in the registry at:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW32TimeParameters

The Windows 2000 operating system can operate as a time client and synchronise to a time server by setting the parameter ‘NTP Server’ to the IP address of a Time Server.

By default, the Windows 2000 machine will synchronize to the specified time server every 8 hours, or 3 times a day. This may not be enough to maintain accurate synchronization and can be easily increased. Setting the ‘Period’ parameter to how many times each day synchronisation is required can reduce the period. Setting the ‘Period’ parameter to 48 will activate synchronization with the time server once every half hour.

The Windows 2000 operating system can also be configured to act as a time server by setting the ‘Local NTP’ registry setting to ‘1′.

After changing any of the registry settings for the windows time service, the service must be restarted for the settings to take effect. The time service can be started or stopped from the service control applet in the Administrative Tools menu. The service can also be controlled via the DOS net command thus:

‘net start w32time’ and ‘net stop w32time’

Windows 2003 Time Service

With Windows 2003, Microsoft has expanded on the original Windows 2000 SNTP time service by providing a true NTP implementation. The Windows 2003 time service, installed by default, can synchronise to a NTP Server. Indeed, by changing registry settings, the time service can act as both a time server and client to synchronize other time clients in the domain.

The ‘Windows Time’ service should be present in the systems service list. The application executable is ‘w32time.exe’. The parameter list for the Windows 2003 time service should be present in the registry at:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW32Time

To configure the Windows 2003 operating system to synchronize to an external time server, edit the following registry entries:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW32TimeParametersType

Set the ‘Type’ registry entry to ‘NTP’, which specifies synchronization to a NTP time server.

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW32TimeTimeProvidersNTPClientSpecialPollInterval

The ‘Special Poll Interval’ registry entry defines the period in seconds that the Windows 2003 operating system should poll the time server. A recommended value is 900, which equates to a polling period of every 15 minutes.

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW32TimeConfigAnnounceFlags

Set the ‘Announce Flags’ registry entry to 5 indicating a reliable time reference.

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW32TimeTimeProvidersNTPServerEnabled

Changing the ‘Enabled’ flag to the value 1 enables the NTP Time Server.

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW32TimeParametersNtpServer

The ‘NTP Server’ parameter is used to provide a list of DNS names or IP addresses, separated by a space, of time servers that the Windows 2003 operating system can synchronize to.

Troubleshooting the Time Service

A number of isuues may be encountered when configuring the Microsoft Windows Time Service. SNTP and NTP operates using the UDP protocol over TCP/IP. Therefore, the TCP/IP network protocol must be active for SNTPNTP to operate. Synchronisation issues may also arise when SNTPNTP attempts to synchronise to an inaccurate time server reference or if network delays are excessive.

Synchronising Network Device and Components

In addition to synchronizing Microsoft Windows servers and workstations, time servers can also be used to synchronise network devices, such as switches, routers and hubs. Any network infrastructure that can synchronise to a NTP or SNTP time server can be pointed to the Windows time server to obtain synchronisation. In this way the whole network and accompanying infrastructure can be accurately synchronised to a time reference.

If you are an Internet junkie and surf nearly 24 hours a day, it may be to your benefit to understand how Web Browser hijacking works and what you can

be to prevent it as well as get rid of this nagging problem should you experience it.

The web contain sites that will override your browser’s homepage setting and then replace it with their own. You can correct this by opening Internet Options in Control Panel and under Home Page, click either use blank or you specify a site of your choice.

But correcting a hijacked home page is much easier than correcting a hijacked Web Browser itself.This happens when your Web Browser is taken over by software with you having little and sometimes no control over its actions.

This happens when you are hit by such browser hijacking programs as CWS or CoolWebSearch.This software appeared in 2003 and is now one of the most invasive browser hijackers.You know you have been struck when you experience the following actions in your browser.

There is a noticeable decrease in overall PC performance.

User’s homepages are Smartsearch or other hijacked files and attempts to remove these are blocked.

Suddenly there appears a new toolbar in your browser

You are bombarded with porn ads and porn is now being bookmarked in your favorites.

Your Internet Explorer browser quickly slows to a crawl.

All web searches are redirected to other sites, in nearly all cases they will be porn.

You will have little and sometimes no control over your web browser.Watch the files you download.

These programs may sometime arrive via a download. If this happens, you need to pay attention to where you are on the Internet and avoid these locations. Try to avoid downloading free screensavers for example.

Free screensavers or screensaver samples are often loaded with spyware, adware, and who knows what other insidious files that lurks within. If you do perform such download do a good virus, spyware scan.

What would be the remedy to get rid of this nightmare. You would not want porn pop-ups appearing on your PC when little Mary or David is nearby.

First go to http://www.helptogo.com and click on the link for a program named Hijackthis. Having this or other hijack removal files on disk will be your first line of defense.

And try to download CoolWebShredder to see if it will remove the program. However, even this may not work.

http://www.softpedia.com is where you can learn more and download this program.

If CoolWebShredder don’t work, you will have to do a complete reformat of your hard drive followed by a clean installation of Windows XP.

If you’re computer is working fine now, take the time to backup your critical files. If you have to perform a clean installation of Windows XP, you will lose programs you installed.

Web Hijacking is growing and fast becoming a real pain in the “you know what” and removing them are becoming more and more a big headache.

You can also go to Google and do a search for the term “web browser hijackers” and find other files you can get to be ready you should run into this annoyance.

Download the file and copy it on a cdrom or floppy disk, depending on the file size. Make two copies of the file and store it a safe place should you need it.

When you visit a site, you may be watched by what is known as a Web bug. This is a tiny graphic which sends information to another computer.It will have your IP and web site address and other data about you.

As you spend time on the Internet, stop and take time to learn as much as possible about these Web Bugs.This bugs may transmit your web site and email address, for example to the web bug’s main computer.

But being in the know ahead of time can save you lots of downtime using the Internet.Have that backup handy, and prepare an XP Recovery Kit and place in a safe and very secure place.

Network Time Protocol (NTP) provides algorithms and defines messages for the synchronisation of time clients to an accurate time reference. This article

discusses how to configure a Linux NTP Time Server to synchronise time with an Internet based public NTP Server.

NTP server systems fall into two categories: primary reference servers and secondary reference servers. Primary reference servers use an external timing reference to provide time, such as GPS or radio clocks. Secondary reference servers synchronise with primary reference NTP servers and offer slightly reduced accuracy. Primary reference servers are designated stratum 1 servers, while secondary servers have a stratum greater than 1.

The NTP Distribution

The NTP source code is freely available from the Network Time Protocol web site. The current version available for download is 4.2.4. NTP is available for the Linux operating systems with ports available for Windows NT. Once the source code is downloaded, it should be configured, compiled and installed on the host machine. Many Linux operating systems, such as RedHat, offer NTP RPM packages.

Configuring NTP

The ‘ntp.conf’ file is main source of configuration information for a NTP server installation. Amongst other things, it contains a list of reference clocks that the installation is to synchronise. A list of NTP server references is specified with the ‘server’ configuration command thus:

server time-a.nist.gov # NIST, Gaithersburg, Maryland NTP server

server time-c.timefreq.bldrdoc.gov # NIST, Boulder, Colorado NTP server

Controlling the NTP Server Daemon

Once configured, the NTP daemon can be started, stopped and restarted using the commands: ‘ntpd start’; ‘ntpd stop’ and ‘ntpd restart’. The NTP server daemon can be queried using the ‘ntpq –p’ command. The ntpq command queries the NTP server for synchronisation status and provides a list of servers with synchronisation information for each server.

NTP Access Control

Access to the NTP server can be restricted using the ‘restrict’ directive in the ntp.conf file. You can restrict all access to the NTP server with:

restrict default ignore

To only allow machines on your own network to synchronize with the server use:

restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap

Multiple restrict directives can be specified in the ntp.conf file to restrict access to a specified range of computers.

Authentication Options

Authentication allows a matching passwords to be specified by the NTP server and associated clients. NTP keys are stored in the ntp.keys file in the following format: Key-number M Key (The M stands for MD5 encryption), e.g.:

1 M secret

5 M RaBBit

7 M TiMeLy

10 M MYKEY

In the NTP configuration file ntp.conf, specify which of the keys specified above are trusted, i.e. are secure and you want to use. Any keys specified in the keys file but not trusted will not be used for authentication, e.g.:

trustedkey 1 7 10

The NTP server is now configured for authentication.

Client Configuration for Authentication

The client needs to be configured with similar information as the server, however, you may use a subset of the keys specified on the server. A different subset of keys can be used on different clients, e.g.:

Client A)

1 M secret

7 M TiMeLy

trustedkey 1 7

Client B)

1 M secret

5 M RaBBit

7 M TiMeLy

10 M MYKEY

trustedkey 7 10

Essentially authentication is used by the client to authenticate that the time server is who he says he is, and that no rogue server intervenes. The key is encrypted and sent to the client by the server where it is unencrypted and checked against the client keys to ensure a match.

This is not about to turn out as an article on Ten Things I Hate About Vista. There is already a great number of technically enlightening pieces that

will do that for anyone. This article will instead focus on what basic common user observations point out as unfortunate Vista innovations from old XP features. Some of the items are humorously simple and superficial. They should not be ignored though because a great majority of people around the world are not technology experts and can only make basic observations. Sometimes though, basic observations are what can make or break a product simply because there are more average people than computer geniuses.

XML

Shockingly, some user tests show that .net applications simply run faster in XP than in Vista. If you have to process great amounts of data on .net applications, you may get frustrated with Vista. Users feel that in this respect, Vista only beats XP in the “looks” category. XP is still on top on the aspect of performance.

Shell

XPs Luna shell has now been dethroned by Vista’s Aero. The elegant 3D look and feel of Aero is probably an effective marketing strategy for average users. Experts point out however that a shell is still a shell and does not show real system capabilities. The Luna shell may have looked plain but it did not point to XPs real performance ability.

Battery Life

In another user comparative test, the battery life of laptops seemed to have held on much longer with XP than with Vista. Vista’s heavy graphics apparently drain more energy than the simpler XP graphics.

Icons and Tumbnails

XPs static icons have now gone six feet under with the introduction of Vista’s live icons and thumbnails. This is good right? Some users feel though that there was absolutely nothing wrong with the unresponsive icons of XP. Again, this is more an issue of superficiality. Live icons and thumbnails don’t mean anything on the performance arena.

Sounds

Users apparently put a lot of thought on system sounds. This is because some feel that sounds can better communicate computer generated messages like battery low or log on or off. XPs grand, booming sound is no longer around. It ha been replaced by more soft and subtle sounds that some users do not find indicative of whatever the system wants to say.

Boot

It is surprising to note that XP seems to boot faster than Vista in some cases. People, of course, want to know why and are wondering if there are also other things that are slower in Vista.

Hardware Requirements

The best thing that is in XP that is not in Vista is that it has lower hardware requirements. Vista is simply too high end in everything. This means that if you have a unit that cannot live up to what is required then you should just forget Vista unless you like having headaches. Users therefore who use their units for basic actions do not need to replace XP at all.

Mail

XPs Outlook Express is no longer around. It is still questionable however, if Windows Mail can really do any better as some claim it should.

Photos

The Picture and Fax Viewer of XP are no longer around. Vista now has Photo Gallery. For ordinary users however, there seems to be no sense in improving the Picture Viewer if all you wanted was to keep pictures. Major editing is still commonly done with other kinds of software.

Search

XP had no indexing feature to help with searches. XP is generally slow with searches. Computers for ordinary use however, do not always need the fast indexed searches provided by Vista.
