Everybody knows that, mainly two types of operating systems can be used for VPS set up. First one is Linux VPS and second one is Windows VPS. There are many arguments about  benefits of Linux VPS and  Windows VPS.

1. Windows is a highly commercial operating system. On the other hand Linux is a free and open source operating system. For this reason there is a cost difference. So Windows VPS is more costly than Linux VPS.

2. Windows VPS and Linux VPS both offer the remote desktop access. Windows VPS provide you the access to stay completely in control and fully conscious of what you are basically editing for your VPS. In case of Linux VPS user can use ssh as text-based remote access which is more difficult and challenging than windows VPS.

3. In case of reliability and security user can much more depend on linux than windows.

4. Windows VPS is not capable to give 100% uptime but Linux VPS is capable of providing a solid 100 uptime guarantee. As it is open source, you can customize your Linux server to handle load spikes together with loading software and programs that should take up less disk space than Windows VPS programs.

PHP (scripting language) , MySQL (Server database) , POP3 (local e-mail clients ) etc can run on both Windows server as well as Linux servers. But  ASP, FrontPage, ASP.NET environment, Windows Streaming Media, MS Access, MS SQL etc are run on only  Windows server.

I mentioned earlier that Linux is a cheap hosting option as compared to windows hosting. It offers the same powerful and high performance output as a windows server without costing too much. A linux VPS hosting proves to be a comparatively good deal as it is cheap, highly efficient and secure.

Virtual Private Server hosting is the golden mean for people who have outgrown their shared hosting resources yet cannot afford a fully dedicated server for their hosting requirements. When your business hosting needs to be upgraded yet you are looking for a cheap hosting option, VPS hosting is the perfect solution. You get customized hosting solution with scalability in terms of bandwidth and storage.

VPS stands for a Virtual Private Server. A virtual private server is created through virtualization technique where partitions are created within one physical server to create multiple virtual servers. Each virtual server has the appearance and capabilities of of running on its own dedicated machine. Each virtual server can run its own full-fledged operating system, and each server can be independently rebooted. Depending on your own particular requirements, you can opt for either managed VPS or unmanaged VPS services. A cheap VPS hosting plan with a popular control panel like Cpanel or Plesk is offered by every web hosting provider

What is the difference between the two types of VPS hosting and which one should I choose?

With unmanaged VPS hosting, you have full control of your virtual hosting environment. You are responsible for the setup, management, and operations of your virtual web server. If you are technically very sound with all aspects of web hosting and servers, you can go with unmanaged VPS. While this is great in terms of privacy and security, it poses another problem. If there is any problem with your VPS account, you will have to deal with it on your own. Whether the problem occurs with the software, hardware, server resources, or applications, the hosting service provider won’t come to your help. That means you have to invest time and effort to make sure someone is constantly monitoring your VPS hosting setup to ensure reliability, uptime, and server stability.

The advantage of unmanaged VPS is that it is very cost effective. Since the web hosting provider does not provide any softwares, and technical or customer support, you can save on those costs.

On the other hand, if you do not have the knowledge or time to manage and administer your own virtual server, you can purchase a managed VPS hosting plan. This is a perfect solution for people who just want to get the improved performance and output from their VPS without being bothered about the technical maintenance.

Your hosting provider will look after the server management, server monitoring, repairs and upgrades or patches that need to be installed. In addition you will get good quality, full time technical and customer support if you buy services from a reputed web hosting provider.

With managed VPS hosting, you only have to be careful about what websites you install on the VPS. The hardware maintenance will be taken care of by the web hosting company.

If you are running a rapidly growing business with increasing demands on your hosting resources, managed VPS hosting is ideal for you. You get fully scalable services as you can increase the storage capacity of the web site and other server resources when required.

As your server grows, all you need to do is inform your hosting company about your requirenment for more resources. They will add all the necessary resources, bill you the additional cost and you continue to concentrate on your business.

In conclusion, an unmanaged VPS hosting is ideal for you only if you have the skills, time or manpower to manage your hosting environment on your own. Otherwise, we recommend you opt for the hassle free, more comfortable option of managed VPS hosting services which leave you free work on your business growth.

Much better performance when compared to any shared or reseller hosting packages. You will be able to host in a custom environment. However, in most cases good amount of knowledge is required in order to host a VPS. If you have a fully managed VPS, that would do much help and also assist you with major operations.

Also, be assured that you need more information on the VPS in order to host it. Best way is to gain as much knowledge from the host as possible. At the time of signup, please make sure you select the right options in order to meet your requirements. Wise selection of hosting package are always good for your pocket. Once you are aware of the vps you need to signup, please make sure the hosting provider can install it for you. You should not host any application or software that can likely over-load the VPS at the end of the day.

Complete isolated environment and indivualism is maintained on a vps at any point of time. Bodhost provides fully managed VPS Hosting package which are monitored 24×7 round the clock. For more information, please have a look at this link VPS Hosting

[root@linux2 etc]# fdisk /dev/hdb

Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won’t be recoverable.

The number of cylinders for this disk is set to 4865.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

Create ext3 File System

The next step is to create an ext3 file system on the new partition. Provided with the distribution is a script named /sbin/mkfs.ext3. Here is an example session of using the mkfs.ext3 script:

[root@linux2 root]# mkfs.ext3 -b 4096 /dev/hdb1
mke2fs 1.27 (8-Mar-2002)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
4889248 inodes, 9769520 blocks
488476 blocks (5.00%) reserved for the super user
First data block=0
299 block groups
32768 blocks per group, 32768 fragments per group
16352 inodes per group
Superblock backups stored on blocks:
32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,
4096000, 7962624

Writing inode tables: done
Creating journal (8192 blocks): done
Writing superblocks and filesystem accounting information: done

This filesystem will be automatically checked every 36 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.

Mounting the File System

Now that the new hard drive is partition and formated, the last step is to mount the new drive. For this example, I will be mounting the new hard drive on the directory /db.

NOTE: You will first need to create the /db directory before mouting the disk! (e.g. mkdir /db)

What I typically do is to edit the /etc/fstab file and add an entry for the new drive. For my example, I will create the /dev/hdb1 entry as follows:

LABEL=/ / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
none /dev/pts devpts gid=5,mode=620 0 0
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0
/dev/hdb1 /db ext3 defaults 1 1
/dev/hda2 swap swap defaults 0 0
/dev/cdrom /mnt/cdrom iso9660 noauto,owner,kudzu,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,owner,kudzu 0 0

After making the entry in the /etc/fstab file, it is now just a matter of mounting the disk:

[root@linux2 /]# mount /db

[root@linux2 /]# df -k
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/hda3 37191660 11016692 24285724 32% /
/dev/hda1 101089 12130 83740 13% /boot
none 515524 0 515524 0% /dev/shm
/dev/hdb1 38464340 32828 36477608 1% /db

By just observing the result of it for your domain you can find that at which node you are getting the data loss higher.

So that’s where you need to proceed with the further investigation about the packet loss for your network.

1) The client should have a dedicated IP for his domain to get the anonymous FTP to work properly.

2) /etc/sysconfig/pure-ftpd needs to be edited to allow anonymous uploads. The ftp server needs to be restarted after this change. Also the public_ftp/incoming directory needs a permissions/owner change, then you will be able to use anonymous ftp with pure-ftpd np. This can be done by :

pico /etc/sysconfig/pure-ftpd

comment –anonymouscantupload

# disallow uploads for anonymous users
# –anonymouscantupload

Save and restart

/etc/rc.d/init.d/pure-ftpd restart

4)At the bottom of the next page, select the group (type) of logical servers to be placed on this physical server.
E.g.: If you add only web servers and mail servers, you won’t be able to add a DNS server to this physical server in the future.
Note: Win, Win Real and MS SQL server groups are not compatible with other groups, and each of them requires a separate physical server.
5)Select Add P.Server in the E.Manager menu to see the newly added server in the list of all physical servers in the system.

After this you will need to add the logical server,

To add a new logical server to H-Sphere, do the following:

1)Go to your admin control panel.
2)Click Add L.Server in the E.Manager menu.
3)On the page that appears, enter the properties of the logical server:
Name: The domain name of the logical server;
Group: The group of logical servers you are adding this server to.
Type: The type of the server.Physical Server: The box where the logical server is installed. If nothing is available in the dropdown box, add this server group to the physical server first.
Description: The note that will help you identify this server among others.
File Server: Reserved for future implementation.
File Path: Reserved for future implementation.
4)Add DNS records for this logical server, as suggested in the DNS Configuration guide.
5)If you are adding a web server, select Shared SSL Manager in the E.Manager menu, click the Edit icon next to the domain name and enter the certificate key and certificate file in the Install completely new certificate key and file pair boxes. Then click the Upload button. This will update the shared SSL certificate installation on all servers, including the newly installed one
