Dynamic DNS notifies the user’s domain that the IP address has been changed and needs to be updated. When someone remotely connects to the domain, they will get the right computer, even if the IP address changes regularly. The Linux command called nsupdate is a utility that allows the user to update a DNS zone without having to manually edit the zone file.

“nsupdate is a fantastic little utility that enable quick and secure DNS zone updates. Setup is quick and painless, and use is fairly intuitive for anyone remotely familiar with DNS, and skilled enough to admin their own Linux system.”

The common tendency of a gamer who wants to hosts multiplayer games is to setup a normal PC box in their home with a regular DSL or cable line. Although this may work for temporary servers or small to medium numbers of connections, gaming on a larger scale can be taxing on an ill-equipped PC and a a home network.

In such cases it might behoove the gaming host to get a dedicated line and server-class computer to host their games. The other option is to purchase a hosting account for a dedicated server. The server can either be an un-managed server with a free Linux distribution or a customized gaming server that has been setup for that specific purpose. Either way, the eventual result is higher quality gaming and more enjoyment for the players.

Hi i would plan to make something like YouTube (video sharing site) but restricted only for my members. Basically if let’s say there are 1000 users every day streaming videos on my site, how much bandwidth do I need and how big the server has to be considering this isnt just regular site but video sharing site for members?

Unfortunately, the answer isn’t simple. Videos take up more bandwidth than CPU or memory, so you will need a server with a lot of bandwidth. How “big” of a server is needed depends on the site’s traffic and size of the videos.

For a site just starting out, I’d probably rent a basic server and upgrade later on once I had a better idea of my needs. If the site grew to a large size, however, multiple servers with tier-1 dedicated bandwidth connections would be needed. Without a powerful connection, users wouldn’t be able to stream video. This sort of infrastructure is very expensive, explaining why video sites need to display so many ads to make ends meet.

Similar services include Domain Privacy at Namesco and Domains by Proxy at Go Daddy. Despite the differences in terminology, each service is exactly the same thing. There are no differences in the depth of privacy offered or the the methods used. Each company simply replaces your WHOIS contact data with theirs and in the event you are contacted using the data, lets you know. Your name, address, real email, and phone number are always kept hidden.

Even if a registrar offers a service like WhoisGuard for free, I would look at the yearly price of the service because generally it’s only no-cost for a year. At only £4.99 ($7.50 USD) per year, Namesco’s Domain Privacy is the cheapest I’ve found.

The administrative fee is charged to all .com, .net, .org, .biz, .info, .name, .jobs, .mobi, and .asia registrations. It is used to pay for the day-to-day operations of ICANN. It used to be quite a bit less, but has increased drastically over the last decade.

Is the fee fair? Every time you register or renew a name, you’re funding Rod Beckstrom’s $750,00 salary and $12.48 million travel budget. I think ICANN has a right to raise funds for its operation, but many domainers have criticized the charge because it gives the organization much more money than it realistically needs to operate. Unfortunately, registrants don’t have much say in the matter. Don’t like it? Then stop registering domains I guess.

Thankfully, every provider will tell you what type of sites are allowed up front. Sometimes the information will be on the sign-up page, but usually it will be listed in the terms of service. If in doubt, you can always ask a sales representative.

While adult sites can be profitable, a good many web hosts don’t want to deal with them for a variety of reasons. Some don’t want to be associated with the content while others have found that adult sites use up a lot of resources and are thus not profitable to host. Look around, however, and you’ll find that there is a decent number of hosts that don’t give a damn.

The benefits of having an entire TLD for adult sites is clear if you are in the adult industry, but what some may not have considered is that it can also have advantages for those trying to prevent children from accessing them. It also provides a definite advantage for tech security professionals who are often given the impossible task of trying to limit access.

Make no mistake, it will not solve all problems, and it is doubtful adult and pornographic sites will limit themselves exclusively to .XXX domains, but part of promoting themselves as legitimate businesses involves making a conscious effort to keep children away from their sites. This could work in favor of both sides of the argument if it is used to its full potential. ICANN is again considering it, and time will tell. But it is certainly worth a second thought.

1. Disable the root password on the real server. Users may decide to use root passwords on their VPS systems, but do not make it easy for attackers to get past them to the real system.

2. Create a user designed just for admin tasks and give it “sudo” rights.

3. Create an ssh user to handle any remote logins and an sftp user for uploads to the real server. Disable remote access for all other users.

4. Run OpenSSH on a port other than the default 22. You can use 2222 or something else.

5. Rely on SSH keys for the two secure users and disable clear password authentication.

“Guagua” is a Spanish nickname for a type of small bus common in urban areas. Often called dollar or commuter vans, these vehicles are privately owned and provide transportation in areas not well-served by public transit.

Other sales of note include pepe.com for €45,000 and gastronomie.com for €35,000. The ccTLDs risultati.it (results) and energieagentur.de (energy agency) each sold for €32,000 and €21,500 respectively. It’s been an active week for the domain market indeed.

At Go Daddy and many other large registrars, however, removing a domain from your account is quite simple. Read step-by-step instructions after the jump.

1. Log into your account. Go to the Domain Manager.

2. Check the domain or domains you wish to delete. Then click the right-most button that says “Delete Selected.”

At most registrars, a dialogue box will appear asking you to verify the action. Afterward, you should get an email confirming the deletion.

If your registrar’s control panel doesn’t have an option for deleting a name, you will have to contact the company directly to remove the registration. Unless you are within the 10-day grace period offered by ICANN, you will get no refund.

Go Daddy Domain Name Manager

Ideally, script installation should be fast, easy to use, and should be simple and direct, avoiding any hacks that make the installations incompatible with normal installations (in case the user ever needs to move their data to another server). But not all hosts are equal in these areas.

Go Daddy, for example, is a well known and highly advertised host, but their control panel scripts installation is mediocre at best. When a user sets up an installation of a script, Go Daddy’s control panel will queue it and make the user wait an undetermined amount of time before the script is actually installed. It is very slow and can be frustrating to a website owner who purchased an account expecting clean and fast script installation.

1. Use one of the gallery scripts supplied and installed by your web hosting provider (if available)
2. Download a free or commercial gallery application and install it on your server
3. Use a third-party photo sharing or gallery hosting site.

The advantage of a locally hosted gallery on your own server is that you can usually easily export your gallery and take it to another host. You also have full control over customization and features (especially if you are using an open source product). With option #1 the biggest disadvantage is that you are limited to whatever your web host provides, which may or may not be available if you switch to another host. The disadvantage of #2 is that you are responsible for updates and maintaining the security and stability of the gallery.

Option #3 eliminates the disadvantages of #1 and #2. Your gallery is maintained by another company and hosted on a remote server. You never have to worry about upgrades. The big disadvantage is that you do not have control over your own content and may not be able to easily export it and take it to another host or gallery.
