Agent Log
A log file that stores data about agents used to enter the site — such as browsers or any other Internet-based software — and all related data.

Anonymous FTP
This feature allows to give public FTP access to a dedicated directory in your account. This allows users without accounts to access files by entering the username anonymous, along with their email address as a password. Because anyone can access files that have been set up for anonymous FTP, it is necessary to be careful to use it only for files meant for public consumption. See also FTP Subaccount and Virtual FTP.


(also referred to as SpamAssassin)The system that allows to trace, filter out and delete spam messages coming to your mailbox. It doesn’t delete messages recognized as spam but only marks them as spam and delivers them in a regular way, which is why these messages also count against your summary traffic.


(also referred to as ClamAV)A resource that checks incoming mail for viruses and if detects any, sends e-mail notification about it and deletes the virus mail. Antivirus resource can be enabled for all mail domains in your account, for specific maildoman and for mail resources of specific maildomain.

A server that contains a master set of data. When there is a change in the data, the authoritative server is updated. See also Primary Server and Secondary Server.
A utility that automatically sends a preset message in reply to all mail sent to the autoresponder’s e-mail address. It doesn’t store the incoming mail as mailboxes do, nor can it be used to send messages other than the preset autoresponse.

Background Job Manager
A utility that allows enabling, starting and disabling selected cron jobs from the admin control panel only.


In website hosting, bandwidth is the amount of information downloadable from the webserver over a prescribed period of time, i.e. a month, a week. If you download a total greater than allowed bandwidth per month, the bandwidth limit will have been exceeded.


Billing Email
Email address set by the user to receive all order confirmations, billing statements, account notifications etc.


Billing Info
Contact information used for billing. It is entered at signup and later can be edited in user CP in Billing -> Billing profile. See below Billing Profile.


Billing Period
Billing period determines how far in advance recurrent fees for billing period resources are prepaid. One-month billing period comes with every new plan by default. You can create multiple billing periods of different length for your customers which allows more flexibility in pricing.


Billing Profile
A billing profile is a set of billing details such as credit card information and billing info. It is required to collect payments and to contact you on financial or related matters. You can have several billing profiles and use them in turn, activating the one you would like to be charged. You can share one billing profile between your accounts, if you have more than one.


Billing Statement
A billing statement is a detail comulative record of paid activity reflecting all charges and credits incurred during a billing period. This means each billing statement represents user’s paid activity during the billing period.


Billing Type
Billing types indicate whether and how users pay for hosting services (Credit Cards, Online Payment Systems, Checks, Trial, No Billing). Plans in H-Sphere can be commercial and free. Free plans are typically used to host your corporate site, use an external billing system, or to disable billing for any other reasons. Commercial plans require payments by credit cards or checks, allow trial hosting for a limited period of time.


Bounce Message
A notification message returned to sender indicating that an email message could not be delivered.

Control Panel
(also referred to as H-Sphere) is the interface provided to maintain and monitor the hosted website. It allows providing a heterogeneous operating system environment to your customers across multiple servers located in various data centers. The CP consists of many subsystems: DNS/Server Management, User Signup, Billing, Merchant Gateways, User/Account/Domain Management, Resellers.

Credit Card Processor

Dedicated IP
An IP address that is set aside specifically for one domain. This means that if someone types in the numeric form of the IP address the same domain will always appear in the browser. See also Shared IP.

DS (Dedicated Server) Hosting
This feature is available in H-Sphere 2.5 and up. Unlike in shared hosting where many client sites are located on the same server and share network bandwidth, here users have their own server and fixed amount of bandwidth limited only by their agreement with the provider. This allows them to choose server software according to their own preferences. Dedicated server is a good solution for those site owners whose profit depends on high load perfomance of their sites e.g. online store runners etc.

DS Bandwidth Billing
There are two approaches to bandwidth calculation: average and 95th percentile. It can also be measured either in megabits per second or in gigabytes. Bandwidth billing type is chosen for a dedicated server plan i.e. all users signed to a particular plan will be billed according to this type determined by the provider.

DS Maintenance
Involves backup manager that receives client backup requests and trouble ticket system through which requests for server upgrade, cancellation, reboot and adding extra IPs are sent. Such requests should be processed manually.

DS Plan

DS Status
Indicators successively assigned to each dedicated server in the system, whether manually or automatically: Disabled -> Available -> In use -> On hold -> Clean up. They help administrators manage and motinor their servers.

DS Template
To simplify billing and managing of dedicated servers with the same parameters, they are added to the system from templates where server’s operating system, RAM and disk space are specified. When setting a dedicated server plan, provider chooses templates to be available in it. As some clients may have special needs, there is also a possibility to add custom-built dedicated servers assiged directly to such clients but not sold via plans.


Delegated Shared SSL
An SSL certificate type that allows your resellers to offer their customers your service domain for third level hosting and wildcard certificate installed on it.


Directory Indexes
A tool that allows to set your own index pages instead of those specified in the default settings. In other words, you can tell your visitors’ browsers which page to load as they hit your domain. Usually, it’s /index.html by default, but you can set any other custom welcome page.


Disk Quota
Disk space in H-Sphere is allocated to customers through quotas, which are set separately for user’s home directory on the web server and each user mailbox and database. Quotas are obligatory plan resources and can’t be disabled. Customers can’t upload and store more MB than the resource quota allows (except for My/Pg SQL DBs) and will get an error message if they try to do so.


Disk Usage
Every 24 hours a cron script scans end user’s FTP home directory, all mailboxes, and DBs to summarize the disk space and make up summary disk usage for the last day. Summary readings of each daily scan are added up and divided by days elapsed from the beginning of the billing month. The resulting amount makes up user’s average summary disk usage.


Disk Usage Limit
User’s initial summary disk usage limit is made up by summary disk usage free units. If by the end of billing month user’s average summary disk usage exceeds it, they will be charged usage (overlimit) fees. To prevent it, users can increase their summary disk usage limit and be charged recurrent fee for monthly resources which is usually less than usage (overlimit) fees.

The Domain resource is responsible for DNS hosting and is required by all specific domain types, such as Domain Registration, Domain Transfer, Third Level Domain, etc. See also Subdomain.

Domain Alias
(also referred to as stack domain) An extra domain name that points to a ‘primary’ domain. Domain alias can have its own DNS zone, custom DNS records and their own mail service.
