Why would my dedicated server need a firewall?Aziby30 Apr 2008

Ultimately everyone needs a firewall if your computer is connected to the internet. Having a server connected online without one nowadays is just the same has leaving your car doors open at night with the engine running in a bad neighborhood, you just don’t do it. Something as simple as enabling a basic firewall can save you days if not weeks of having the clean up the mess of an un wanted user gaining access to your system and causing trouble. A basic firewall would have the effect of atleast stopping someone who is randomly scanning servers and comes across yours to test it for any vulnerable spots. Simplest of rulesets in place should effectively deter any mild or casual intruder. However depending on the level and determination of the unwelcomed guest, a more advanced configuration may need to be used.

When using a Windows or Linux-based server, the firewall built-in will allow you to select basic settings to stop unknown users from connecting via RDP(Remote Desktop Protocol) which essentially is the Linux equivalent to gaining root access on your system. Other services such as IIS, MSSQL, MySQL, FTP, Email, or Apache can all be thoroughly filtered to not only block unauthorized access, but explicitly only allow connections to these services from trusted IP addresses. So if your co-workers, development team, or just yourself need access to the server. Then a simple firewall filter will be there to save the day. Depending on your particular needs for the system things can indeed get a little bit advanced when it comes to setting these rulesets up.

For a more advanced server setup and firewall configuration, your best choice will be to utilize a Cisco PIX. The PIX firewall is like one of the Swiss army knives of the internet. It delivers robust user and application policy enforcement, attack protection, and secure connectivity services in cost-effective, easy-to-deploy solutions. These purpose-built security appliances provide multiple integrated security and networking services, including:
-Advanced application-aware firewall services
-Robust site-to-site and remote-access IPSec VPN connectivity
-ward-winning resiliency
-Intelligent networking services
-Flexible management solutions

Here at SingleHop we offer a few choices for firewall.s which can effectively better secure your network. Both windows and linux based machines have their built-in firewalls which can be managed both by us or yourself if need be. Just as mentioned above, if a more robust configuration is needed then you also have the choices of the PIX-501 and 506-E models. The choice will be yours to decide which firewall service better fits your needs.

What are the differences between Windows Server 2003 Standard and Web editions?ericby29 Apr 2008

Windows Server 2003 LogoAfter you have decided to go the Windows route while shopping for a dedicated server, you will be presented with multiple options for the platform. We provide the Windows Server 2003 Web, Standard, and Enterprise editions for use on our servers, with the 32 and 64 bit flavors of Standard and Enterprise. Most people will only need either Web edition or Standard, depending on what their needs are. Enterprise is used as well, but it is far less common than the latter two. Enterprise is built more for people that know exactly what they need from the operating system, such as clustering, so I will just be covering Standard and Web editions today.

Good Food Quick!Ronald Cotoniby28 Apr 2008

There are many ways you can have really good food really quick. It usually makes people think that you have taken a very long time for preparation. I can usually make a meal for 2-4 people with around 10-15 minutes of preparing the food. The most time is actually spent cooking something. I usually use my oven as you can go do other things while the food is cooking. This can be talking to your guests, or cooking something else.

I generally like to have a few different things in my meal. I have to include some veggies in everything I cook. I also like to include a meat and some Carbohydrates if I can. I am going to give you a recipe of one of my favorite things I like to cook, that meets most of these requirements. I like quick meals as I am always coming up with new ideas for SingleHop. I do not have a lot of time to cook, but I love to eat and cook for friends. This is especially important as I am often on call.

Help! My Website is Outgrowing my Dedicated Server!Garett Murphyby25 Apr 2008

Some people may think that their website is so small and insignificant that it will never become as big, or as popular, as a site like YouTube or MySpace. With the slashdot and digg effects, even the smallest of blogs could become extremely popular (or just receive tons of unexpected traffic) overnight. But even then, most people don’t expect their site to become as big as some of the more popular sites and, as such, don’t plan for it.

Fedora, FreeBSD, or CentOS?Ronald Cotoniby24 Apr 2008

Greetings, SingleHop Customers!

Today, I’d like to explain the similarities, differences and details of some of the most popular Unix-based operating systems available, as denoted in the title of this post.

To begin, let me go over some of the things each have in common. Each of the operating systems are based on an Enterprise-level Unix Operating System and are very much suited to running a Web Server or any other type of server. They all have the same software available to them. You can compile anything from source or install a binary package. Some examples of those packages are Apache, PHP, MySQL and Exim.

What is a Hyper-Threaded Processor and Does it Matter?Samby22 Apr 2008

There is a lot of confusion these days with all the new processor technology that has come out over the last few years. Intel has released a great amount of different technologies such as Hyper-Threading, the Core series, as well as VT technology. Now, I’m sure after reading these terminologies that Intel has coined you’re thinking “what does that mean for me?” Well I am so glad you asked!

FM-200 RULES! To the Devil with Flames!Ayseby21 Apr 2008

As is universally acknowledged, fires in buildings are pretty awful things. But something truly awful, is a fire in a data center. I previously wrote a blog post about how America has the 4th most network integrated economy in the world. A fire in a data center can truly be catastrophic. The possible loss of data and equipment damage, plus the lives put in danger are truly frightening prospects.
Although, to move out of dark territory, there are amazing prevention methods to avoid this:

There are a few methods of waterless fire protection in data centers, as well as strategic structure preparation. The most common reasons for data center fires are:
- Accumulations of underfloor combustible materials, such as unused wiring insulation and connectors
- Paper storage and supplies within data center space
- Tape storage materials stored outside of the designated storage space
- Improper storage and maintenance of fuel for emergency generators
- Failure of personnel to adhere to stated guidelines
- Fuel system piping leaks
These are things that are easily remedied by not running wiring under the floor, but rather where it is visible and then basic vigilance in terms of data center maintenance and staffing. We are proud to say that at SingleHop, we absolutely demand all of these safety measures, as well has having a truly awesome (as in inducing gasping awe) generator system in the event of power disruption.

Also, there are state of the art and not quite so state of the art fire suppression systems. The older waterless fire suppression system was known as Halon. It was introduced in 1973 and was one of the first gaseous fire suppression agents. These systems are still around in some places, though not too much anymore considering it was banned in 1994, as it is an ozone depleting substance and requires a breathing apparatus (gas mask) when it is released in high concentrations.

We definitely don’t use Halon at SingleHop. We take pride in using a data center that is as up to date as possible and environmentally friendly. We use a gaseous fire suppressant known as FM-200 (Heptafluoropropane), which looks like this:
FM-200
And:

This compound prevents this:
FIRE!
FM-200 is a great fire suppression agent used in more than 70 countries. FM-200 is insanely fast at suppressing fire, often in 10 seconds or less, and can stop ordinary combustible, electrical, and flammable liquid fires before they cause significant damage that make buildings look like this:

FM-200 is the fastest fire protection available, meaning less damage, lower repair costs, less disruption, and, most importantly, the protection of human life.

FM-200 can also be safely stored and used where people are present. It doesn’t require a gas mask like Halon. It’s stored in cylinders as a liquid and pressurized with nitrogen, meaning that it saves huge amounts of storage space.

Shared Hosting or Dedicated Hosting?Zakby20 Apr 2008

admin

Shared hosting is right for a lot of people! It’s a great way to save money for other things that might be more important to you, but keep in mind that there are restrictions. A friend sent me a link to this video:
http://www.youtube.com/watch?v=0sWFgRIDliY&feature=relatedcrammed

That is exactly what shared hosting is. Hundreds if not thousands of websites are crammed on to one server, and for 99% of them it works. If your site receives a lot of visitors though, or if reliability is important to you than you should upgrade to a dedicated server. Just like this video shows, profitability to the hosting provider relies on getting as many websites on one server, and many times resources run short.

So You’ve Decided to Start a Shared Hosting Company…Dan Ushmanby17 Apr 2008

Dan

In this post, I will explore the various technical aspects that you should consider when launching a shared hosting company. I won’t discuss marketing or sales tactics, because that is an entirely different conversation.

Many business people who want to start Web Hosting Businesses go for reseller accounts. Reseller accounts offer a very inexpensive and simple way to get into the business, requiring nothing more than a Pay Pal account and a reseller account at any number of providers. If this sounds like your plan, then you may want to continue reading.

Reseller accounts are great because they have a very low cost (low entry barrier would be the business term.) However, they don’t offer the control or security that one would need to really start a business. Here are some things to consider:

- In most reseller setups I have been able to review, the company hosts their billing software on the same server as their clients.
- That same server hosts the billing and customers of other hosting providers who resell for the same firm

This creates two very big problems. First, if another companies users abuse the server and take it down, you’re down, your support is down and your billing is down. Second, if some other user does something that results in the server being compromised, then you are also at the mercy of the hackers.

The solution for this would be to start a hosting business with two servers. The first server should be ‘locked down’ and should only handle billing and support ticketing. Ideally you would separate these two also, however it gets expensive then. The second server would be your first shared account server, and you would put your customers on it. This separates the two aspects of your business (administrative and customer websites) and decreases the likelihood of data breach.

Marketing, sales, design, and everything else aside, one could start a hosting business on the purely technical side by leasing two dedicated servers and building a website, installing a commercial billing system such as ModernBill, Ubersmith, Client Exec or many others (SingleHop uses the Ubersmith system, but that is an entirely different story on its own.)

The next thing you need is proper system administration. You need advanced system administrators to handle your servers and keep them running. Dedicated Servers are like pets, you have to feed them, give them attention, keep them alive or they will die. This includes pro-active monitoring of hardware as well as keeping software up-to-date. Since you don’t want to start with to much overhead, hiring an administrator to handle your servers on day-one would be a bad move. Instead, you should consider a managed server which basically means that your provider (be it SingleHop or whoever) will use their system administrators to monitor and manage your servers.

I hope this short post helps anyone thinking of entering the market for Shared hosting.

Best wishes,

Dan
