iServer has authored an interactive web content manager and file browser, iManager, which allows a Virtual Server administrator to use their favorite browser client (Netscape Navigator, MSIE, etc.) to perform simple file manipulation tasks such as uploading files, copying files, deleting files, and much more. The iManager "wizards" walk you through a step by step process for each task.
The iManager utility will allow both root administrative access as well as access for each of your POP user accounts. However, the POP users are restricted to operate in the home directory that they are assigned. Thus each POP user is afforded the convenience of using the iManager wizard interface, and the administrator is assured that security is maintained.
iServer Interactive Root (iRoot) Utility
iServer has also authored an interactive Virtual Server administrator utility,
iRoot, which allows a Virtual Server administrator to remotely perform routine
administrative tasks such as adding POP accounts, removing POP accounts,
adding and deleting e-mail aliases, and many more.

You can now order your Virtual Server with iManager preinstalled as one of the basic configurations. If you do not have it installed at the time you order your Virtual Server, you can install it later by following the following steps.
To install iManager, telnet or SSH to your Virtual Server and perform the following steps:
- Make your home directory the current working directory, type
"
cd" at your telnet prompt and then hit the return key. - Untar the iManager archive file, type the following:
tar -xvf /usr/local/contrib/imanager.tar - Customize the look and feel of iManager by modifying
the files
headerandfooterwhich contain the open body tag,, and close body tag,respectively. (Hint: use iManager to edit these files- see instructions below).
You can now use the iManager utility on your Server by accessing the URL:
http://your_domain_name/cgi-bin/admin/gateway.cgi
You can either open the URL with your browser directly, or link the URL to either text or an image on one (or more) of your web pages. You may have noticed a hidden image at the bottom left of each of the iServer web pages. The image, which represents the greek letters for "ISI" (for Internet Servers Inc), is linked to our copy of the iManager utility (yes we use it too). Click on the image to check it out. (Please note: you will not be allowed permission to use our iManager gateway. After you have installed iManager on your site, you will simply use your URL (http://your_domain_name/cgi-bin/admin/gateway.cgi) to access your copy of the iManager gateway.

iManager AuthenticationAfter you have installed iManager on your Virtual Server, open up the URL listed in the installation section. You will be asked to provide a valid login/password pair and some path information. The login/Password pair can be one of any found in your "~/etc/passwd" file. Therefore you can either use your root or administrative login and password or one of your POP users can use his or her login/passwd pair to gain access to the iManager utilities.
The Path Specification is the directory or file that iManager will use as its current working directory or currently selected file (see Using iManager for an explanation of the Currently Selected File and the Current Working Directory). If a non-root login is specified, the Path Specification is checked against the home directory of the user (as listed in the ~/etc/passwd file). If the path specification is outside of the user's home directory, access is denied. Each non-root user is restricted access to the iManager utilities inside of his or her home directory. There is no such restriction placed on the root or administrative login.
To illustrate authentication with iManager consider the following examples:
-
Using your Administrator Login and Password
Authenticate yourself with your administrator login and password and set the path specification to "/www/cgi-bin/admin/". A list of the contents of the "/www/cgi-bin/admin/" directory will be displayed including the
header and footer files (mentioned in
the installation instructions above).
Select the "[ED]" link beside the header or
footer entries. This will load the contents of
the selected file into a form. You can then simply edit the
contents and upload the changes back to the Server.
Using a POP Login and Password
If you are using a Fully Functional
Virtual Server (Server B) you have the capability of adding
individual POP accounts to your Server. Each POP account has an
entry in your Virtual Server's "~/etc/passwd" file which includes
the full name of the user, the user's password (crypted of course),
the user's home directory specification, and his or her disk quota
if FTP privileges have been granted.
Any of your POP account users may enter in their POP account name and password to authenticate themselves. However, they must specify a path specification that is valid for their account or they may leave the path specification blank, in which case iManager will determine their home directory. Thus they are restricted access only to their home directory or subdirectories in their home directory. This allows your POP users the convenience of iManager utilities without compromising the security of your Virtual Server. Since POP authentication is supported in iManager, your POP users can do for themselves what you as the Server administrator used to have to do for them by hand.
