admin — Sun, 06 Dec 2009 17:26:28 +0000

Lately, we have been talking about the Linux Dedicated Servers, in this article I am going to show you the three important tools which are useful for your Linux Dedicated Server Hosting.

A fact that most of the people belonging to the website hosting industry knows that the products and applications released for Linux are FREE. The tools listed below are also free to download on Internet.

GRUB : Basically, this is boot loader application unveiled under GNU project available for free. If you wish to use 2 operating systems on one single machine, you will need an option to choose the OS you want to run on start of your machine. GRUB is one of the multiboot specification that can fulfil you needs. This is an application which lets you to install and run two different operating systems (OS) on the same machine.

You can see the option, only if the GRUB is installed on your Linux Dedicated Server, otherwise the feature will not work. One more advantage of this feature is that you can select various images of the kernel and pass boot time parameters on a single operating system partitions to such kernels.

Most of the Linux Dedicated Server Hosting providers will help you to install GRUB boot loader on your server. If not, there is a possibility that you will have to install the GRUB application of your own.

TCP Wrapper : This application is also a free tool that you can download via Internet. TCP Wrapper basically acts as a firewall for your own Linux based dedicated server hosting. A fact that the incoming packets are being monitored by the TCP Wrapper, hence it is stated as an acting firewall.

On linux dedicated server hacking attacks might be possible, hackers may attempts to login into your server. TCP Wrapper ensures it by checking the external source is aurthorized to connect your linux server or not. If the attempt is unauthorized, the application will denied the login permission.

It is also known as a domain computer program, one of the best programs by using it you can keep hackers far away from your Linux dedicated server.

Zend Encoder and Zend Guard are few software’s which encode specific files and Zend optimizer is a free linux application software which runs these files while boosting the running speed of PHP applications. Basically, it is an application required by most of the scripts to run the scripts on your linux dedicated server while decrypting and running them on the fly while increasing runtime performance.

How to Improve Security on Dedicated Servers?

admin — Wed, 02 Dec 2009 17:00:41 +0000

Server Security is the main concern for most of the clients or webmasters while choosing a web hosting service provider. Compare to other web hosting package, dedicated server security is much more secure. When you are using a shared hosting account, you have to share your server and resources so security concerns are already down.

On Dedicated Server Hosting you can avoid the hacking attempts by following the below security measures.

Changing Passwords : Changing your password is the first and important security measure to take with a dedicated server. While configuring your dedicated server, don’t forget to change the passwords as it is the primary step of security. To avoid the hacking attempts and malacious programs completely, you should change the passwords every quarterly. Make the password difficult by including numbers, alphabets in lower and upper case and few special characters so that guessing will be hard for hacker.

Use of SSH Instead of FTP : Disable the application you are not using. For example, if you aren’t using the FTP, just disable it, so that there will be no chance for security hole. Generally, hackers are always in search of dead holes and as soon as they get it, they sneak into them. However, if you do use FTP program, ensure not to send passwords or any private info via ftp, as because they are sent in plain text can be easily detected.

SSH is much more secure than Telnet. Telnet is one of the greatest security risks on a dedicated servers and make maximum usage out of your secure shell.

Firewall Protection : This is another important security tool for your dedidcated server. A good firewall can detect hacking attempts and notifies you while they are on their way. Though its windows or Linux both of them are not completely virus free, so make sure to update your firewall and softwares.

Data Backup : You may lose your valuable information or data by typing a wrong command. Make sure you take a backup of your data on monthly or weekly basis.

As an administrator just taking care of the above security measures is not enough, you will still need to carry out a regular maintenance on your own dedicated servers.

Mirroring of Dedicated Servers

admin — Thu, 12 Nov 2009 10:02:57 +0000

To describe server mirroring in a very simple way,it is the process of duplication of data between two servers.If the primary server fails, the mirrored server can immediately take its place without any down time.
Dedicated Server mirroring is a bit expensive but an effective strategy for achieving fault tolerance. The reason for being expensive is because each server must be mirrored by an identical server whose only purpose is to be there in the event of a failure. A less expensive technique that is becoming increasingly popular is clustering of the Dedicated Servers.
Dedicated Server mirroring is nothing but a real time process of data synchronization i.e.from one server which is called the primary server to the other called as secondary server.This technique ensures that an exact copy of the data available on the primary server is created on the secondary server. One can also put it as utilizing the secondary server as a backup server that synchronizes all the data of the primary server.Rsync technology is used to synchronize the data onto the other server.

There are few very useful advantages of Mirrored Dedicated Servers:

a)Dedicated Server mirroring architecture is effective for fault tolerance.
b)With the Mirrored server architecture users can achieve 100% uptime guarantee.
c)The data synchronization process of mirrored servers are done in real time,therefore one can have and updated copy of each data file on both the servers.
d)Rsync is an effective technology and can very well track the changes made to the data on the servers and replicate the change onto the secondary dedicated server.This is a noticeable feature that only the changes and not the entire file is backed up saving resources and time.
e)There is no downtime and hence no loss of data with this disk to disk synchronization of data.
f)This architecture enables an effective use of resources as both the servers are active and working together,this ads majorly to the redundancy of both the servers.

Use of RAID 1 with the Dedicated Servers can be an effective option to achieve fault tolerance.This architecture usually involves two webservers,primary server mirrored by an identical server,which would act as the primary server incase the primary server fails.

Media Streaming and Dedicated Servers

admin — Thu, 12 Nov 2009 07:54:35 +0000

Live audio and video streaming has been the very rapidly growing trend in the online world.Audio video broadcasting,teleconferencing,Internet radio,weather relay stations, etc which are a part of streaming are on the level of services.Inorder to flood the internet with the streaming services over the Internet,it is very important that have a good server to host your website.These should be high performance fast servers with ample resources to fulfill the resource intensive needs of the streaming applications as well as the traffic using these services.

The web hosting services you choose to host your streaming website should be capable of offering Dedicated Servers with the appropriate capacity.These servers are also known as shoutcast dedicated servers.These servers are ideal and capable of offering direct,secure and most importantly fast access to the users.These servers are also specialized in offering uninterrupted services to the users.

Installing shoutcast on Linux Dedicated Servers is as simple as installing it on Windows Dedicated Servers,below is how you go ahead doing it.

Client server model is what Shoutcast servers are based on,therefore,you musn’t run it as root,else it may create issues with the server security.You should alternatively create a shoutcast user and then proceed further.

The below procedure is what you can follow:

a)With SSH,you login to the root of the server
b)Then, adduser shoutcast
c)passwd shoutcast

You must login as new shoutcast user or as su USER

=================
su shoutcast
=================

You need to download Shoutcast from the nullsoft website :

http://www.shoutcast.com/downloads/sc1-9-2/shoutcast-1-9-2-linux-glibc6.tar.gz

Now you must extract the shoutcast:

tar -zxvf shoutcast-1-9-2-linux-glibc6.tar.gz

Use the following command now

=================
rm -rf shoutcast-1-9-2-linux-glibc6.tar.gz
mv shoutcast-1-9-2-linux-glibc6 shoutcast
cd shoutcast
=================

Further,configuring shoutcast onto the server is really simple.You can follow these simple steps for that purpose:

First of all,you need to edit the configuration file.

=================
pico sc_serv.conf
=================

or you can use vi which I prefer, a bit more advanced to use.

=================
vi sc_serv.conf
=================

You can set some important configuration options. Change these settings in the file:
MaxUser
Password
PortBase
uncomment AdminPassword and set an admin password.

You may make the required changes to the settings as per your requirements.Don’t forget to save it.This concludes the installation and configuration of shoutcast onto your dedicated server.

You can now use shoutcast using:

=================
./sc_serv sc_serv.conf
=================

Dedicated Server Migration

admin — Mon, 09 Nov 2009 22:09:09 +0000

Moving your Dedicated Server Hosting data is not complicated if you plan properly.

A complete migration of a website consists of transferring the website data itself, it means all the HTML and most probably PHP and MySQL files and CGI programs. For this you will also need to alter the DNS (Domain Name System)information for the website and for the routing of the website email. DNS (Domain Name System) keeps the information that translates IP addresses to human-readable domain names. For any Website migration, the two important DNS records are the address (A) record, which says the browser the IP address of the Web server, and the mail exchange (MX) record, which guides mail servers how to route the email.

When you desires to migrate your Web site to another Dedicated Server hosting provider, you will have to update DNS to point browsers to the new location of your website. All though, it can take at least 12-48 hours for DNS updates to propagate to all DNS servers on the web.

A lot of times the domain name is registered through a 3rd party domain name registration company. When you transfer the website, your domain name and company remains as it is, the only thing that changes is your web hosting provider. If your domain name originally came with hosting, you may need to contact your old hosting company to see if you can separate the hosting package from the domain name.

Proper preparation and planning is the best way for successful migration. Before moving you must inform your users or customers of the upcoming upgrade. It is always a good decision to prepare a “server down for upgrade” page for your old website. Please note the IP addresses of your new and old servers; these will come in handy when DNS is still in flux.

First decide the time when you wants to upgrade, meaning when your server is least busy. If you have website statistics, use those to determine the best time. To reduce down time, it is best to make the DNS changes several hours before you actually move the domain. As long as your mail server is running on the new server, you will not lose any email messages. If you have a static website, you can copy over the data before you switch DNS and no one will ever know your hosting provider changed.

The DNS changes you will need to do are updating the MX and A records to point to your new server. For that, you will have to access the cpanel provided by the domain name registration company from which you obtained your domain name. new MX record will need to point to the new server. For instance, a records. MX records can take some time to propagate through the Internet. To avoid mail loss you will need to check your old mailbox at least once a couple of days after the move. You will also need to use the IP address of the old mail server rather than its domain name, as you won’t be able to rely on mail.domain.com to check the old mailbox, as that will point to your new server. Depending on how much control you have of your old server, you could shut down the mail server after modifying the MX records, in which case incoming mail would get in line until the new mail server is running, at which point it would be delivered without any problems.

How to move a website files?

As soon as you have changed the DNS figures, after that it’s time to deal with the data itself. HTML and PHP files are not hard to move; just use a good FTP program and copy the data from one server to the other. If you have SSH access to both of the servers you can copy the files directly. If you don’t, you will have to download the files to a local machine and then upload them to the new server.

How to move Database from one dedicated server to the another?

1)Moving databases is a little bit complicated. For example if you are using MySQL, there are lots of ways to copy over the data. One is to do a dump of the data into a file and then copy that file to the new server and populate the new database. To do this you use the mysqldump command:

$ mysqldump -p -u username mydatabase > mydata.sql

Once copied onto the new server your can populate your new database with the mysql command:

$ mysql -p -u username mydatabase < mydata.sql

2) If you are not having SSH access to your server hosting package then you will not be able to use these MySQL commands, but you can still use a tool such as phpMyAdmin which handles MySQL administration over the Web. phpMyAdmin has excellent dump and restore features, though for the restore there is a maximum upload file size of 2,048KB. You can use compression to maximize your chances of squeezing all of your data into 2MB.

3) If you do not have SSH access and you have too much data for phpMyAdmin to handle, go for a MySQL synchronization tool called SQLyog Job Agent (SJA).

4) If all of the above fails you will need to ask the support team of your old hosting company to dump your database for you. Then you will need to ask the support team of your new hosting company to populate the new database.

If you have a website with active data, such as an e-commerce website, you will need to make special provisions for the DNS update delays. As the DNS changes propagate through the Internet some people will see your new website and others your old. This could create problems for you. Suppose if a customer placing an order on your old website after you have moved all the data over to your new website.

You can take care of this problem by 2 different ways.

The first thing you need to do is stop taking orders from the old website once you have started the move. At the checkout stage display a respectful notice asking customers to come back in a couple of hours, after which they should be taken to the new website. If you don’t have that kind of control over your website then the best thing is to close down the old website by replacing its index.html with a notice saying the server is down for upgrades and will be back soon. An alternative solution is to use a synchronization tool like SJA to make sure any changes made on the old website get propagated to the new one.

At last, watch out for incompatibilities between the software on your old server and that on the new. Try to confirm that any difference in versions of important software like MySQL and PHP won’t create any problems.
