Web Hosting – Mistakes & How to Solve Them?

   Posted by: Anand Maheshwari   in Internet

Web hosting is a very strategic decision for any business and therefore, it should be very cautious in choosing the right kind of service provider. Entrepreneurs tend to be quite prudent about opting for the web hosting company but still they tend to commit some simple mistakes. Here is a list of the most common mistakes that should be avoided by any prospective web master:

Every one gets attracted to the cheaply priced websites, but there are many disadvantages that come along with these servers, like denial of common services. This usually occurs because mostly in the case of low priced servers, the owner has oversold the bandwidth. As a result, due to a large number of sites on the same server, the server often gets into a downtime. Try to be a smart Webmaster and use judgment to avoid falling into the trap of buying these websites. These kind of amazingly low charging websites can also prove to be a hindrance in coping up with increasing traffic due to their limited technical resources.

Often, webmasters tend to go for the purchase of websites without a specific enquiry on their part on what are the actual needs of their website. So, to make sure that you get a deal with the right web host just make a list of all the resources that your site will require when you decide to go for an up gradation. This will actually facilitate an expansion of your website as then you can discuss your needs with the provider.

Another common mistake that the users tend to do is purchasing the space from an auction. These deals are quite attractive but they usually come with a plethora of in-built conditions and regulations that curb any future expansion of the site in terms of disk space.

A very simple fallacy that all the webmasters usually indulge in is not having the contact numbers and e-mail addresses of the service providers. This leads to huge problems in times of server downtime in restoring the server. If you have the requisite contact numbers, getting in touch with the technical personnel for troubleshooting can be expedited. A key to choosing the optimal service provider is always to go through the host’s website. It will give you important clues about how he/she is going to develop your website. Any poorly designed host’s website clearly indicates that they are not going to devote much efforts to the user’s website.

A website’s key strength is its software because it defines the resistance of the site. One should always try to have the latest versions of software installed on the website to protect it from any kind of virus and hacker’s attacks. Ask the host to have a back up of the site, so that it can be replaced easily in the case of a system failure or crashing.

In the end, try to check whether the testimonials published on the set are authentic or not. You can get these numbers from the web hosting service provider, but if they are reluctant in providing them to you, then definitely the reviews are definitely fake.

Web Hosting & Online Business

   Posted by: Anand Maheshwari   in Internet

With the coming up of Internet in such a big way, online presence has almost assumed a paramount amount of importance for any business. There are two key aspects of making any online business successful, creating a high quality, user-friendly and an informative website i.e. web designing and secondly, managing the site well that refers to web hosting services.

The market is brimmed with a high range of web hosting services that includes both free as well as paid services. Well, the features offered certainly vary with the charges of the service provider. Certainly, every business needs to choose the package according to its specific needs like scale of the business, data security, amount of technical support and uptime. Since, a web hosting service provider is critical for the success of any business, one cannot choose it in a haphazard manner. What one needs to do is to find the best assortment of features at the lowest possible rates.

The market can surely offer a business a very large number of discount web hosting services, but it needs to look out for the highest quality package. The costs are easily condensed with the help of such budget service providers, because you are sharing the server with an umpteen number of other clients. But, the downside of such a deal is loopholes like lower uptimes owing to frequent server crashing, lower disk space and bandwidth, unreliable and in continuous customer support. With a lower uptime, a site can often lose a large percentage of the business. But with paid packages, higher uptimes are a sure-shot guarantee.

A very important factor for choosing any service provider is the fact that some online businesses usually require help in setting up a site. For such businesses, choosing up site hosting companies with free website build up features with wizards, templates, and easy to follow tutorial software can really be an added advantage. All these features including free domain name listing can really go in favor of a user and anticipated by it in a package before choosing a web hosting company.

Most of the businesses that are dealing in online sales need to have user-friendly features like shopping carts on their site. For them, it is very necessary that customers are easily able to make payments online through credit cards after purchasing products and services. Without any shopping cart feature, online sales for such businesses would be nearly impossible and their profits would be seriously reduced. For businesses keen to cut costs on the shopping cart feature, licensed downloadable shopping cart facility is also available.

With services offered by professional web designers included in paid packages, you can easily make your site more alluring for the customer, and also expedite your business transactions and operations. An attractive, website with clear-cut user-information and features is a great marketing tool that can help in expanding the traffic and sales of a business in a very effectual way. Therefore, web hosting companies offering such services should always be preferred by any online business and here, benefits do take an override over the costs.

The Weider X-Factor Home Gym Fitness Product

   Posted by: Aimee Jones   in Health and Well Being

The new year is upon us and now is the time to get back in shape. You’re probably thinking about starting a new diet or exercise plan, and you’re definitely considering what different kinds of equipment you might be interested in.

A new fad and fitness equipment is what is known as a door gym. These kind of started with the pull up or chin up systems where you would have a device that will connect them to your door frame to help you be able to do a pull up. Now, these systems have advanced to the point that they now have resistance bands and can function as a full home gym system.

These new types of equipment are very cost effective and offer an interesting alternative to the much larger and bulkier home fitness systems that many people grew up with. It might not reproduce everything you can get in the gym, but it does offer something different.

The Weider X-Factor is the latest innovation from Weider to hit the market. This gym is similar to others yet. It is designed perhaps maybe a little bit better. Also, it is cheaper than most gyms.

The setup process is incredibly simple. You just clip the door to the resistance bands via the corner clips, and now your home gym system is ready to go. Instead of spending hours setting up a traditional home gym system this only takes minutes. Also, the whole system can fit in your gym bag. Good luck trying to do that with a Bow flex.

The Weider X-Factor also comes with a series of fitness DVDs that you can use to help you get started with the system. There are three different DVDs, and they focus on completely different areas. If you rotated them in your weekly workouts, you probably get in shape fairly quickly.

The price is fantastic at only around $100 if something almost anyone can afford. When you compare that to a gym membership or different piece of home fitness equipment is extremely price competitive. The only system I’ve seen that might even be a better deal as the P90X.

That being said, the Weider X-Factor is a great value and a very interesting new product. If you’re looking to get in shape, you really should consider this system. After all, if you just do this three times a week for 30 minutes of time, you?d be in shape before you know it.

Cisco Exam Certification: How To Build A CCNA Home Lab

   Posted by: Bob Marshall   in Internet

Many people ask me what would make a good CCNA lab? Well, that can be a tricky question based upon your budget and future Cisco aspirations. So lets start off with a few basic concepts I hope we can all agree on. Real Routers

You need a physical router as the simulators just dont have the ability to give you the hands on you need to see what happens when you disconnect a cable, put a cable in the wrong location or just plain configure the interface incorrectly. Dependant on what you do by mistake, you may see either the interface or protocol go down and based upon that it should give you a clue of where to start troubleshooting(hint, what layer is the interface at and what layer is the protocol at?). Anyway, you will come to find quite quickly that mistakes you make on Router 1 are affecting Router 4 all because you did not screw in a cable properly. No simulator can simulate that, so a router is invaluable.

I also get occasionally asked if someone can use their D-Link router or such in their lab. That class of home router generally does not support protocols such as RIP, OSPF, IGRP, etc. nor do they support the Cisco IOS which is a majority of the CCNA exam. So the answer is they are not really applicable to building your Cisco CCNA lab.

How Many Cisco Routers Do I Need?

Two routers really are required to see if anything works. If you have a very limited budget, you can receive value from only purchasing a single router over working with a simulator. However, you will not be able to see the main thing we are trying to accomplish. The propagation of route tables and the routing of data! The only way you can see if your configurations work, is to have at least two routers. That said, if you can afford a kit with more than two routers, it will enable you to exercise more complex scenarios. Therefore, I strongly recommend that you purchase a dual router kit or better that comes with all the accessories you need. Otherwise you can spend days or weeks trying to find all the little extra pieces you need to get your lab up and running. I mention this as some other resellers are selling their kits with 2500 routers and they are not including transceivers. Well how will you use the Ethernet AUI ports without them?? So this is basically how I view it. One router will give you the ability to run the commands on it and allow you to memorize the correct syntax and context in which to run the commands. Two routers will allow you to be able to see route table information propagate, data propagation and path election. In addition, you will see basic device elections. With three or more routers you will get all of the above and full device elections. Hopefully these tips will help you pick the right CCNA lab kit for you budget.

Can We Build A Lab That Will Cover Every Single CCNA Exam Concept?

We get this question quite often. Yes, we can, but it is not realistic for most customers who are self studying as this will cost well in excess of $5,000. If you have that sort of budget available, we suggest you pick on of the CCNP kits as that will get you through your CCNA exam and well on your way to your CCNP certification.

How Many Cisco Routers & Cisco Switches Do I Need To Complete Your CCNA Lab Workbook?

Our CCNA Lab Workbook was designed with the knowledge that most of our customers cant afford a large lab. Keep in mind, that you will see a variety of labs that were written for three of four routers below. That does not mean you cant complete most of them. It just for the most part means they will not be as complex as they could be.

Number of labs requiring only one router ” 7

Number of labs requiring two routers ” 11

Number of labs requiring three routers ” 19

Number of labs requiring four routers ” 4

Number of labs requiring one or more switches – 8 What Are Some Things I Need To Consider For My CCNA Lab?

Two new topics have popped up for the new Cisco CCNA 640-802 exam. They are IPv6(IP Version 6) and SDM(Security Device Manager) which is a GUI based way to configure your routers and switches. A common question is can the Cisco 2500 series routers support IPv6? Yes, they can if they are maxed out with 16MB of DRAM and Flash. Here are some more specs on Cisco routers and required DRAM and Flash to support IPv6 assuming you have the correct IOS.

As mentioned before, SDM is Ciscos Security Device Manager and is the GUI option to configure your routers. It is not supported on some of the older models. But the good news from a lab perspective is that you do not need it on every router to get a good grasp on how SDM works. The Cisco 3640 router is going to be the cheapest way to get SDM with a 10mb Ethernet interface and the Cisco 2600XM series seems to be the cheapest way to get SDM with a 100mb Ethernet interface.

Finally, I also have an IOS version column. As you can see above, the Cisco 2500, 2600 and 3620 models only support 12.3 whereas the Cisco 2600XM and 3640 units support 12.4. So if you want to have exposure the latest IOS that is running on routers in the real world, right now that is 12.4. But if your budget does not allow for it, you will still find value in the routers that are running the older 12.3 IOS.

Why Do You Sell Routers With Memory That Cant Run IPv6?

Not everyone has the budget to support every feature. So you will see that we still offer Cisco 2500 router kits with 8MB of DRAM and 8MB of Flash as being able to practice on routers that support 85% of the concepts is better than nothing at all if you budget is tight. Anything Else You Can Suggest?

Well, a few things. The Cisco 2500s are serviceable routers for your CCNA studies still as long as you have the proper IOS and maxed out memory with all the accessories you need. You might say, but they are only 10mb routers. True, but they still work. The major drawback besides the aforementioned lack of SDM and 12.4 support is that with 10mb routers you cant do your inter-vlan routing labs with them(which is true of any of the 10mb routers). So just make sure you have at least one 100mb router in your lab so you can do inter-vlan routing and that takes care of that issue and helps to keep the cost of your lab down for those with a tight budget!

You want to make sure your router can support IPv6 as doing those labs will really help the IPv6 concepts sink in. Finally, SDM is more than likely the wave of the future, so you might as well start to get used to it now! Do I Need A Switch?

This can be debated a few different ways. First some people will say that 80% of the test is based on routing. To which I will agree. But with only a small margin of error between passing and failing, not fully understanding switching concepts such as VLANs, STP, and root elections could be the one question that stands between you passing and failing your exam. There will be some switch questions which are memorization based such as What is a Layer 2 protocol used to maintain a loop-free network? Thank goodness we memorized STP. That said, it would be nice for us to be able to actually see the switching concepts work. So this is basically how I view it. One switch will give you the ability to run the commands on the switch and allow you to memorize the correct syntax and context in which to run the commands. It will also allow you to do some of the VLAN labs. Two switches will allow you to see VTP Domain & VLAN information propagate. In addition, you will see basic device elections. With three or more switches you will get all of the above and full device elections. Remember, we are only at the CCNA level right now so we will not need a Layer 3 switch like a 3550 just yet. But it is a cool concept of your CCNP studies. Finally you may ask why do some of my dual router kits not have switches in them. Well because you can quite simply go to the section on our site labeled Switches and add the switch you would like to be a part of your kit. The switches don’t need extra transceivers, ports and such so I don’t really have to kit them up with the routers. We do have some of the larger kits that have both routers and switches in them too. What Switch Should I Get?

This is one that there is so much debate on these days. I will give you my thoughts on it and there are a hundred different ways you can build a lab. I will give you the information and let you decide how you want to build your lab.

The Cisco 2950 switch is the switch that is covered on the test and has the exact IOS command set that you will see on the lab. So if you can afford one, it is great to get. But sometimes when customers only have a $200 budget, I cant suggest for them to get a switch and forego the routers. After all, the test is 80% routing! Back to the Cisco 2950, this is the best switch for the test if you can afford it.

But lets say you cant afford that switch , but still want a switch, what is next? We have the Cisco 2900 series. This is a step down from the Cisco 2950 and supports all the same CCNA test commands except the switchport and global vlan command. So with that knowledge, this switch may just work for you.

Finally, there is the Cisco 1900 series switches. There is not a lot of demand for these so they can be purchased very cheap. Some people say they have absolutely no value in a CCNA lab. I tend to disagree for the most part. You may ask me, hey, what are you smoking? The IOS that the Cisco 1900 series switches support is not the IOS that is on the test so how can it be useful? Well, lets go into knowing that they IOS commands on the 1900 series are not the ones that are on the test. Ok, so we are not going to focus on them(remember, there are only a very few switch IOS commands on the CCNA exam in regard to syntax), but concepts that I find many people having a hard time understanding in how STP works, how the device elections are handled and such. Those concepts work exactly the same way on a 1900 as they do on the 2950 switch. Not to mention that you can do your VLAN, VTP and other similar labs on the switch to get an understanding on how they work. So hopefully you can see why I still carry them to help customers who are on a tight budget get exposure to such concepts. *Note, as of January 2009 the prices have come down on the 2900 series switches to the point it does not seem to be of great value for us to still carry the 1900 switches. The price between the two switch types is so close it is better to spend the extra few dollars and get a 2900 series switch.
