iHost allows users to build websites with database backend in a shared LAMP hosting platform. Please refer to Web Hosting Solution Overview for more information.

Choose a Domain Name

Faculties or departments that wish to host their website on iHost can apply for a domain name in the ust.hk name space for easy reference. A valid domain name registration request must meet the following criteria

  • The domain name is primarily requested in the interests of HKUST rather than for personal use.
  • The requested domain name should not contain any reserved or sensitive wording.
  • Obscene names are not allowed.
  • Alphabets, digits and hyphens can be used, but a hyphen should not be used as the first character of a domain name string. Upper and lower case letters can be used but the domain name string is case insensitive.
  • Use the shortest domain name as far as possible. A domain name should be three to 20 characters.
  • To minimize the chance of duplicating domain names, you are advised to choose a unique domain name (usually an abbreviation) that can best represent the function/nature of your service or event.
  • All domain names are registered on a first-come-first-served basis.
  • You should inform ITSC if the requested domain name is no longer needed.
  • Some departments may have their own delegated sub-domain (for example, “cse.ust.hk”, “math.ust.hk”, “bm.ust.hk”,). If you want to form a domain name under a delegated sub-domain (such as “xxx.cse.ust.hk”), you may need to contact the system administrator of the relevant department managing the sub-domain.
  • When necessary, domain name applicants may be asked to provide further information to support the request.
  • ITSC reserves the right to make the final decision on approving a domain name.

Apply for an iHost Account

To apply for an iHost account together with a relevant domain name representing your site, please submit an online request via Application for HKUST iHost Service.

Assign a New Password/Password Reset

Once you receive your iHost account information, you are strongly recommended to change the account password before publishing any web pages for security reasons. To assign the account a new password:

  1. Log on to the iHost server through any SSH application e.g. “PuTTy" (please note that previous Secure Shell Client does not work with the latest version of the Ubuntu OS).
  2. Change the password using the following command:
  3. Type in the new password and re-enter again for verification.

If you forgot the password and need to reset your iHost account password, please send an email to cchelp@ust.hk. 

Check Your Quota

Follow the steps below to check the available disk space of your iHost account:

  1. Log on to the iHost server through PuTTy
  2. Use the command below to check your quota:
    quota -u <account_name>

e.g. quota -u webitsc if you have the “webitsc” iHost account.

Publish Your Web Pages

Your iHost account already provides a public_html directory with proper access rights. You can publish your web pages under the public_html directory using any applications that support secure FTP, such as FileZilla, or Dreamweaver.

After you have published your home page, you can access it through the following URL:

e.g. http://itsc.ust.hk for an “itsc” domain name.

The web server returns the index.html file under the “public_html” directory as the default web page. If the file index.html cannot be found, a “Forbidden” page will be displayed.
