Next we will see a simple Internet Access scenario which will help us understand the basic steps needed to setup an ASA 5510. Assume that we are assigned a static public IP address 100.100.100.1 from our ISP. Also, the internal LAN network belongs to subnet 192.168.10.0/24. Interface Ethernet0/0 will be connected on the outside (towards the ISP), and Ethernet0/1 will be connected to the Inside LAN switch.

The firewall will be configured to supply IP addresses dynamically (using DHCP) to the internal hosts. All outbound communication (from inside to outside) will be translated using Port Address Translation (PAT) on the outside public interface. Let’s see a snippet of the required configuration steps for this basic scenario:

Step1: Configure a privileged level password (enable password)
By default there is no password for accessing the ASA firewall, so the first step before doing anything else is to configure a privileged level password, which will be needed to allow subsequent access to the appliance. Configure this under Configuration Mode:

ASA5510(config)# enable password mysecretpassword

Step2: Configure the public outside interface
ASA5510(config)# interface Ethernet0/0
ASA5510(config-if)# nameif outside
ASA5510(config-if)# security-level 0
ASA5510(config-if)# ip address 100.100.100.1 255.255.255.252
ASA5510(config-if)# no shut

Step3: Configure the trusted internal interface
ASA5510(config)# interface Ethernet0/1
ASA5510(config-if)# nameif inside
ASA5510(config-if)# security-level 100
ASA5510(config-if)# ip address 192.168.10.1 255.255.255.0
ASA5510(config-if)# no shut

Step 4: Configure PAT on the outside interface
ASA5510(config)# global (outside) 1 interface
ASA5510(config)# nat (inside) 1 0.0.0.0 0.0.0.0

Step 5: Configure Default Route towards the ISP (assume default gateway is 100.100.100.2)
ASA5510(config)# route outside 0.0.0.0 0.0.0.0 100.100.100.2 1

Step 6: Configure the firewall to assign internal IP and DNS address to hosts using DHCP
ASA5510(config)# dhcpd dns 200.200.200.10
ASA5510(config)# dhcpd address 192.168.10.10-192.168.10.200 inside
ASA5510(config)# dhcpd enable inside

The above basic configuration is just the beginning for making the appliance operational. There are many more configuration features that you need to implement to increase the security of your network, such as Static and Dynamic NAT, Access Control Lists to control traffic flow, DMZ zones, VPN etc.

In this article I will explain the basic configuration steps needed to setup a Cisco 5505 ASA firewall for connecting a small network to the Internet. We assume that our ISP has assigned us a static public IP address (e.g 200.200.200.1 as an example) and that our internal network range is 192.168.1.0/24. We will use Port Address Translation (PAT) to translate our internal IP addresses to the public address of the outside interface. The difference of the 5505 model from the bigger ASA models is that it has an 8-port 10/100 switch which acts as Layer 2 only. That is, you can not configure the physical ports as Layer 3 ports, rather you have to create interface Vlans and assign the Layer 2 interfaces in each VLAN. By default, interface Ethernet0/0 is assigned to VLAN 2 and it’s the outside interface (the one which connects to the Internet), and the other 7 interfaces (Ethernet0/1 to 0/7) are assigned by default to VLAN 1 and are used for connecting to the internal network. Let’s see the basic configuration setup of the most important steps that you need to configure.

Step1: Configure the internal interface vlan
——————————————————
ASA5505(config)# interface Vlan 1
ASA5505(config-if)# nameif inside
ASA5505(config-if)# security-level 100
ASA5505(config-if)# ip address 192.168.1.1 255.255.255.0
ASA5505(config-if)# no shut

Step 2: Configure the external interface vlan (connected to Internet)
————————————————————————————-
ASA5505(config)# interface Vlan 2
ASA5505(config-if)# nameif outside
ASA5505(config-if)# security-level 0
ASA5505(config-if)# ip address 200.200.200.1 255.255.255.0
ASA5505(config-if)# no shut

Step 3: Assign Ethernet 0/0 to Vlan 2
————————————————-
ASA5505(config)# interface Ethernet0/0
ASA5505(config-if)# switchport access vlan 2
ASA5505(config-if)# no shut

Step 4: Enable the rest interfaces with no shut
————————————————–
ASA5505(config)# interface Ethernet0/1
ASA5505(config-if)# no shut
Do the same for Ethernet0/1 to 0/7.

Step 5: Configure PAT on the outside interface
—————————————————–
ASA5505(config)# global (outside) 1 interface
ASA5505(config)# nat (inside) 1 0.0.0.0 0.0.0.0

Step 6: Configure default route towards the ISP (assume default gateway is 200.200.200.2)
—————————————————————————————
ASA5505(config)# route outside 0.0.0.0 0.0.0.0 200.200.200.2 1

The above steps are the absolutely necessary steps you need to configure for making the appliance operational. Of course there are much more configuration details that you need to implement in order to enhance the security and functionality of your appliance, such as Access Control Lists, Static NAT, DHCP, DMZ zones, authentication etc.

These are the 5 tips with which you can “speed up your windows”. By following these simple tips your windows will run faster.

(A) “speed up your windows” by Performing a Boot Defragment

The following is the simple way to ‘’speed up XP startup”: make your system do a boot defragment, which will put all the boot files next to one another on your hard disk. When boot files are in close proximity to one another, your system will start faster.

On most systems, boot defragment should be enabled by default, but it might not be on yours, or it might have been changed inadvertently. To make sure that boot defragment is enabled:

1 Run the Registry Editor

2 Go to HKEY_LOCAL_MACHINESOFTWAREMicrosoftDfrgBootOptimizeFunction

3 Set the Enable string value to Y if it is not already set to Y.

4 Exit the Registry

5 Reboot

(B) “speed up your windows” by using a Flash Memory to Boost Performance

This is an other way for your “windows speed up”. To improve performance, you need to install additional RAM memory. It’ll let you boot your OS much quicker and run many applications and access data quicker. There is no easiest and more technically elegant way to do it than use eBoostr.

eBoostr is a little program that lets you improve a performance of any computer, powered by Windows XP in much the same way as Vista’s ReadyBoost. With eBoostr, if you have a flash drive, such as a USB flash thumb drive or an SD card, you can use it to make your computer run better. Simply plug in a flash drive through a USB socket and Windows XP will use eBoostr to utilize the flash memory to improve performance.

The product shows the best results for frequently used applications and data, which becomes a great feature for people who are using office programs, graphics applications or developer tools. It’ll surely attract a special attention of laptop owners as laptop upgrade is usually more complicated and laptop hard drives are by definition slower than those of desktops.

(C) “speed up your windows” by Removing Fonts for Speed

This is the tip number three to ” speed up your windows”.Fonts, especially TrueType fonts, use quite a bit of system resources. For optimal performance, trim your fonts down to just those that you need to use on a daily basis and fonts that applications may require.

1 Open Control Panel

2 Open Fonts folder

Move fonts you don’t need to a temporary directory (e.g. C:FONTBKUP?) just in case you need or want to bring a few of them back. The more fonts you uninstall, the more system resources you will gain.

(D) “speed up your windows” by Optimizing Display Settings

This is tip numer four and important one to “speed up your windows” .Windows XP is a looker. But it costs you system resources that are used to display all the visual items and effects. Windows looks fine if you disable most of the settings and leave the following:

1 Show shadows under menus

2 Show shadows under mouse pointer

3 Show translucent selection rectangle

4 Use drop shadows for icons labels on the desktop

5 Use visual styles on windows and buttons

(E) “speed up your windows” by Detecting and Repair Disk Errors

This is my last tip for you and very important one.Over time, your hard disk develops bad sectors. Bad sectors slow down hard disk performance and sometimes make data writing difficult or even impossible. To detect and repair disk errors, Windows has a built-in tool called the Error Checking utility. It’ll search the hard disk for bad sectors and system errors and repair them for faster performance.

1 Follow Start > My Computer

2 In My Computer right-click the hard disk you want to scan and click Properties

3 Click the Tools tab

4 Click Check Now

5 Select the Scan for and attempt recovery of bad sectors check box

6 Click Start

I hope you like these tips and these will be helpful for you in “speed up your windows”.

If you have an older computer that tests the memory every time you boot and goes through multiple startup screens there is a way to eliminate that. Restart your computer and enter the bios. Look for boot options and enable quick boot. This will enable you to skip all the unnecessary startup screens and other sequences.

Not all PCs have that option. Next you will want to look at your antivirus program. Going to the options menu and make sure it is not scanning every time you start your computer. If it is disable this option, this can really slow down your boot time.

You’ll also want to do a general cleaning up your hard drive. You can do that by selecting your hard drive and running the disk cleanup. You can also remove any old programs that you no longer use, the less software your PC has to load, the faster it will be. Next you will want to eliminate any startup programs that you do not absolutely need. The problem is Windows XP made this difficult. There really is no easy way to do it. You can download a third-party program like tweak UI. Or most registry repair programs will enable you to remove startup programs safely.

Next you will want to do a full virus scan and also a scan for spyware and ad aware. If you haven’t performed maintenance on your computer for a while you might be shocked at what it finds. All of the above suggestions may help, but in most cases, the biggest problem for slow boot is a corrupted or damaged Registry. You will need a good registry repair program to fix it.

Your computer’s registry contains all the files and settings that your software needs to reference every time it loads. Over time, from uninstalling and installing software your registry collects a lot of orphaned files. These need to be cleaned or repaired. Improper shutdowns, viruses, crashes, improper uninstalls, or spyware will cause your registry to become corrupt or bloated over time.

When you boot your computer, the startup sequence refers to the registry to load software. It may be looking at a corrupted files and software that is no longer working or on your computer. In most cases this is the reason why Windows XP boots
so slow. You should perform regular maintenance on your registry to keep it fully optimized. Doing so is like giving your computer or a tuneup. You will be amazed at the increased performance and speed up your computer.

• First of all check the configuration of your PC or Laptop. Properly verify whether your system’s configurations meet the minimum criteria of running Windows 7 or not. If you don’t have the required configuration first you need to enhance that in order to run Windows 7 properly.

• If you upgrade you software and hardware
then you will definitely see a number of magical changes in operating the Windows 7. As it is the most recent operating system available in the market, Windows 7 requires supports of latest software and hardware.

• If a less spiffy interface is OK with you then stop using Aero in your Windows 7. You know well that Aero is a wonderful interface that comes with Windows 7. This effect is very attractive, eye-candy and gives lots of special-effects, but it consumes lots of RAM. If you have a large quantity of RAM then it’s ok, but if you don’t have then you are advised to remove this effect you’re your Windows 7.

• You are suggested to clean all your temporary files on a regular basis. Everyday at least once go to “msconfig” and remove all your unnecessary programs from taskbar. This will enhance the operating speed of Windows 7.

• Properly see whether your system has registry problem or not, if you found any kind of registry problem then first resolve it, otherwise the OS problem will not be resolved.

• Uninstall all the programs and software that you do not need. Through this way you will be able to free up hard-disk space, which will help you to run Windows 7 properly.

• Do not install lots of software in your computer that will not help you in future works.

If you follow the aforementioned processes then you will not face any kind of problem while working in Windows 7 platform. If, after following all of them properly, you face any further problem in your OS then do not hesitate to call a remote tech service provider. The Remote computer repair service providers will resolve all kinds of Windows 7 related problems in easiest of manner.

Setting up a wireless printer is not a complicated matter to accomplish. It can take as short as five steps to get the whole thing done.

Step #1: The Location of the Wireless Printer.

Since more than one computer would be making use of the wireless printer. It makes sense to figure out the best place to put it. The wireless printer should be set up at a place at home or in the office that is accessible to everyone and where there is ample space for paper, printer ink and other such paraphernalia.

Step #2: Bluetooth or Wi-Fi?

There are two connectivity choices when it comes to setting up a wireless printer, and these two choices are none other than Bluetooth or Wi-Fi. Most new computers and printers nowadays are equipped with either Bluetooth or Wi-Fi capacities, but if not, it is easy to get a wireless card that can be plugged using a USB port. The only difference is that Bluetooth printers has a smaller range than Wi-Fi.

Step #3: Enable Printer Sharing

The server computer’s operating system must be informed that the printer that will be added to its network is a wireless printer. In Windows Vista, this is done by accessing the network settings in the Control Panel and then activating file and printer sharing in the local area network settings.

Step #4: Share the Printer.

The other computers on the network must also be set up for using the wireless printer. To do this in Windows Vista, open the Control Panel in the classic view and then open Printers. Right click on the printer that is going to be shared, and then open Properties. In Properties, check the box that allows the printer to be a shared device.

Step #5: Continuous Troubleshooting

Wireless networks are prone to interruptions, and so it is important for whoever it is that is maintaining the wireless network at home or at the office to keep the connections to the wireless printer active. Nothing is more irritating that setting up a wireless printer and then encountering numerous glitches afterwards.

Intel disclosed the attack in a regulatory filing late Monday. It doesn’t necessarily mean that Intel was infiltrated or that the attackers were the same ones that targeted Google.

Intel spokesman Chuck Mulloy said Tuesday that the attack on Intel wasn’t broad-based like the one that hit Google. He said Intel isn’t aware of any intellectual property being stolen.

Intel, like other major corporations, faces constant computer attacks. Mulloy said the company was only pointing out there was a connection in terms of the timing of the Google attacks as part of a disclosure to investors about the company’s risks.

The disclosure comes amid heightened fears of state-sponsored espionage targeting corporate computer networks. Google revealed last month that its network was attacked from inside China and that the intruders stole intellectual property — an attack that Google says could cause it to leave China.

Google said at least 20 other companies were targeted as part of the attack, but those companies weren’t identified. Software maker Adobe Systems Inc. and Rackspace Inc., a Web hosting service, have acknowledged being targets.

Intel is the world’s largest maker of microprocessors, the “brains” of personal computers and servers, with about 80 percent of the worldwide market for those chips.

The first iPads are due to hit the market in March but it was revealed at the Mobile World Congress in Barcelona that several other iPad-like tablets from major PC manufacturers would also hit the market this year, running a range of operating systems including Google’s Android and Windows.

At the recent TED conference in California, Wired became the first magazine to show off a complete, specially designed version for tablet devices, which readers can browse using touch. Many other major titles, including The New York Times, GQ, Vanity fair and Sports Illustrated, have tablet apps in the works.

Wired creative director Scott Dadich worked with Adobe’s senior experience design manager, Jeremy Clark, over six months to design the digital version of the magazine with the help of Adobe’s AIR software.

Aunty expresses interest

In an interview in Barcelona, Clark said he had received an email from the ABC this morning seeking to strike up a similar partnership.

“They think they have a lot of interesting content that they’d like to get out to tablet devices,” he said.

Adobe has already worked with Britain’s public broadcaster, BBC, to bring iPlayer – which lets viewers stream the network’s programs from the last seven days – to desktops using Adobe AIR.

Clark said Australian newspaper publishers had also expressed interest but he could not provide further details. He believed tablet versions of Australian newspapers would be available in the second half of this year, once tablet devices are available to buy.

Clark has not yet heard from any Australian magazine publishers but he expects this to change rapidly as Wired’s tablet edition becomes more well-known.

“The point here is that we are entering a new era of media, where we finally have a digital platform that allows us to retain all the rich visual features of high-gloss print, from lavish design to glorious photography, while augmenting it with video, animations, additional content and full interactivity,” said Wired editor Chris Anderson.

Prepare for tablet onslaught

Aside from the iPad, other vendors are preparing to release similar tablets based around Nvidia’s powerful Tegra chip, which can play full high-definition 1080p video and even run PC games such as Unreal Tournament 3.

Nvidia’s senior technical marketing manager for Tegra, Sridhar Ramaswamy, said he expects 10-15 tablets, most running Google’s Android, to hit stores this year, starting in April.

“It will be a worldwide launch – we’re working with major OEMs so I fully expect these products to be available in Australia,” he said.

In the Wired tablet edition, which will be available mid-year, readers can flick through pages of the magazine by swiping their finger on the tablet’s touchscreen both horizontally and vertically. Because the content is digital, video and photo galleries can be embedded into pages and ads can also be interactive.

One demo showed an ad for Camaro and readers can use touch to rotate the advertised car 360-degrees.

“Right now what we’re seeing is this perfect storm of the classic slate form factor devices that are large enough that they are almost the size of the printed media, so it has the visual impact that you need,” said Clark.

“The touch capabilities make it as intuitive as using a physical book or magazine. People have really become accustomed to the iPhone and all the touch gestures.”

Publishers can retain their familiar workflow

Adobe software tools such as InDesign are already the predominant tools used by publishers to design printed magazines. The same designers can use these tools to create the digital tablet version, while additional staff are employed to build the interactive elements such as video.

The iPad’s Safari browser does not support Flash but Adobe has developed tools to allow Flash-based content to work on the device, provided that the apps are accepted by Apple on its App Store.

Clark said publishers had been putting their content online for free under the belief that online advertising would be enough to sustain their businesses, but the revenues were much lower than expected and online banners ads were not effective in terms of brand awareness.

“Over time as these web ads have been using certain standards people know how to block them out of their brain while they surf the web,” he said.

Furthermore, today, when newspaper and magazine content is published online, the design from the print product is stripped away and the content loses some of its design integrity.

“It’s heart breaking for print designers who spend a week or two designing something and look at their website and see that none of their designs are reflected there. It’s stripped out, it’s boring, it doesn’t really have a visual impact,” he said.

Magazines delivered to tablets using Adobe’s software will still contain ads but these will be better designed, richer pages like those featured in printed editions.

“I think it will be closer to the magazine ad model where there’s almost as much ads as there is editorial content and people value the ads,” said Clark.

But Clark believes not just tablets, but desktops as well, could benefit from rich digital magazines and newspapers that more resemble the printed product.

“A lot of publishers have given up on the desktop because they associate it with the web,” he said.

Manufacturers clearly value the open-source nature of Android, which they can customise to their hearts’ content. But Microsoft’s Windows Phone 7 is definitely a contender and it will be interesting to see what devices the phone makers can come up with by the end of the year.

Here are my top 10 mobile announcements and phones from the show:

Windows Phone 7 – There’s a lot riding on Microsoft’s next mobile operating system. For the last 18 months Windows Mobile has lagged newer rivals like the iPhone, BlackBerry and Android. Its market share has dropped.

Microsoft CEO Steve Ballmer’s keynote speech at the Consumer Electronics Show in Las Vegas was dry and lacked major new announcements, so I was skeptical about whether Microsoft could pull it off in Barcelona.

The jury is still out as we wait until Christmas to see some final handsets but from the early Windows Phone 7 prototypes at MWC, it’s clear Microsoft has wiped the slate clean and started fresh with a new platform and a revamped, innovative user interface.

The demo version I saw was an early version and slightly buggy but i’m impressed with the tight integration with social networking sites and online email and calendar sites. The inclusion of Xbox Live for multiplayer gaming and a Zune music player puts it squarely in iPhone territory.

But Microsoft’s insistence on manufacturers keeping its tile-based UI may limit phone makers like HTC, which has done wonders to dolly up Windows Mobile 6.5 with its Sense interface. And the inability to upgrade existing Windows Mobile phones to Windows Phone 7 may frustrate those who recently shelled out for a 6.5 device.

Samsung Wave – Samsung is going out on a limb by introducing a completely new phone platform, banking on developers supporting it with enough interesting and useful apps to compete with iPhone and the open-source Android platform from Google.

It’s risky. But the 3.3-inch Super AMOLED touch-screen display is gorgeous and Samsung will have complete control of both the hardware and software, which has definitely been beneficial for Apple with the iPhone.

Sony Ericsson Xperia X10 mini pro – Looking at this handset in a picture is deceiving. While other smartphone makers are moving to bigger screens, like the HTC HD2’s giant 4.3-inch display, this one is tiny at 2.6-inch.The device measures just 90×52x17mm.

But big phones aren’t for everyone and Sony Ericsson makes it work with a good touchscreen user interface and the Timescape app, which puts friends’ Facebook posts, Tweets, messages and calls into a single stream. Other apps can be downloaded from the Android market.

HTC Legend – Most phones have a front and back that clip together but the Legend’s casing is machined out of a single block of aluminium. As soon as I saw it I wanted one. The Legend is an Android phone running HTC’s highly customised, intuitive Sense user interface.

HTC Desire – It’s not as pretty as the Legend but while the Legend has just a 600MHz processor, the Desire offers a much gruntier 1GHz chip. It runs the latest version of Android, 2.1, and features a 3.7-inch screen – the closest you’ll get to the Google Nexus One, which hasn’t yet been launched in Australia. The Desire will be available in Australia from Telstra in April.

HTC HD mini – Think of this one as a smaller version of the giant HD2. Like its sibling, the HD mini runs Windows Mobile 6.5 and includes the unique ability to launch a personal WiFi hotspot, which users can connect to on a laptop to browse the web over their mobile’s 3G network from anywhere.A very cool feature that I would love to see replicated by other manufacturers.

Samsung Beam – It doesn’t look like this phone will come to Australia any time soon but it’s worth a mention because it’s one of the first handsets to include a built-in projector for viewing content stored on the phone on any wall.

Samsung definitely gets points for innovation but the market for this one may be somewhat limited and the projector is only really effective in darker rooms. The battery is drained in about three hours with the projector on.

Asus-Garmin Nuvifone A50 – This is the fruit of a partnership between electronics maker Asus and GPS navigation specialist Garmin, so it’s designed to replace the GPS device in your car and double as your primary mobile. It runs the Android operating system but the interface has been completely redesigned to the point that it barely resembles other Android phones.

Sony Ericsson Vivaz – The Vivaz has a QWERTY keyboard and 3.2-inch touchscreen but, unlike most phones, is also capable of shooting high-definition 720p video and includes an 8-megapixel camera.

Motorola Milestone – Motorola has been extremely quiet in Australia over the last few years but i’m hoping it comes to market with the Milestone, which is similar to the Droid that Motorola launched in the US.

It runs Android 2.0 and has iPhone-like multitouch support, with users able to pinch the 3.7-inch screen to zoom on web pages, maps and photos. The phones comes with Motorola’s turn-by-turn GPS navigation software, MOTONAV, a slide-out QWERTY keyboard and a 5-megapixel camera.
