HAN FAQ - Frequently Asked Questions
Here you can find the frequently asked questions:ยท
General Information
 Administrator: Some of my Internet resources (such as e-journals, for example) require a user login. Do I have to supply all of my users with the required user name and password?
 H+H: No. This login data is exchanged exclusively between your HAN server and the Internet resource provider's Web server. Your users do not see the login happening. Even the "login" Web page remains invisible (see Chapter 5, "HAN Administration" for details).
Administrator: A lot of my Internet resources (such as e-journals) require the IP address(es) of the computer(s) used to access them (i.e., the range of IP addresses used at a given enterprise, campus or other university facility). Do I have to notify the Internet resource provider every time something is changed in these addresses?
H+H: No. All the provider needs is the IP address of your HAN server. With HAN, any changes in your own IP-address structure remain a company-internal matter.
Administrator: The e-journals that are accessible based on client IP address can be called up at any time from any of our campus computers. Can our users access these same resources from home, or while attending an out-of-town conference?
H+H: Yes. For just such cases, HAN offers the option of authenticating users in the HAN system (e.g., using an NT domain account, over an LDAP interface, etc.).
Administrator: Can I block selected computers in my system from accessing specified resources (e.g., particular e-journals), even if these computers are within the permitted IP address range?
H+H: Yes. With HAN, you have the option of making selected e-journals available to a limited group of users, independent of the user data registered with the resource provider. You can define access permissions based on such cri-teria as NT group membership, IP address, NT domain, etc.
Administrator: Is the HAN server a proxy server that I have to configure in all my cli-ent browsers?
H+H: No. The HAN server is not a proxy; no client-side configuration is necessary.
Administrator: Some of the e-journals we subscribe to permit only limited parallel user access. Is there any way to have HAN apply the same limits and automatically block access as needed in order to keep within the agreed access limits?
H+H: Yes. HAN is equipped with special license control functions so you can specify the maximum number of users that will be able to access a given e-journal at any one time. If this maximum is set to 5, for example, and a 6th user in your network attempts to access the e-journal in question, an information page generated by HAN is opened in the user's browser in place of the requested e-journal page. You can design this information page yourself.
Administrator: Can I generate statistical evaluations concerning the e-journals ac-cessed from within my network?
H+H: Yes. HAN comes with powerful statistics tools that let you process Web traffic statistics, such as frequency of calls, duration of access, and data volume downloaded, in a variety of tables and graphs.
Administrator: I have several different e-journal subscriptions for which the resource provider has assigned identical login data. Do I have to enter this data for each e-journal separately?
H+H: No. In HAN you have the option of grouping e-journals that have similar proper-ties. This means you can edit the account data for all group members simultaneously.
Administrator: When my users are unable to access an e-journal due to a problem on the side of the resource provider, they are often presented with a confusing error message opened in their browser. As a result, I get a lot of phone calls from users who are not sure whether there is anything they can or should do about the problem themselves. Can HAN help me to avoid these time-consuming misunderstandings?
H+H: Yes. With HAN, you can deactivate access to the e-journal yourself as soon as a problem is detected, and compose the error message opened by HAN when the e-journal is requested.

EJL Interface
Administrator: Our solution pertaining e-journals has been administrated over the Regensburg EJL. Can both systems, HAN and EJL, work together?
H+H: YES. In cooperation between the Regensburg EJL and H+H a special interface has been developed so that EJL and HAN ideally work together. Thereby all of the EJL assets remain unchanged, and, in addition, all of the HAN functions are available.
Administrator: How much effort would it take to integrate my present EJL system in HAN?
H+H: To integrate your EJL in your HAN-Server you merely need to make a few settings in the EJL administration and set up an email account on your mail server (POP3) for the data interchange. To put it into operation you simply create a list of titles in the EJL administration and import of the list to your HAN-server. After that all you need is a mouse click to divert the requests to the EJL-e-journals to your HAN-Server. The entire administrative work is reduced to these mouse clicks in a running EJL-HAN-Installation.
Administrator: If an e-journal changes, in particular, its URL, do I have to manually change this data on my HAN server?
H+H: No. The HAN-relevant data will be transmitted automatically to all HAN-servers known to the Regensburg EJL. This happens automatically. You merely have to setup the email interface EJL/HAN once.
Administrator: Will I be notified that the data on my HAN-Server have automatically been changed over the EJL/HAN-interface?
H+H: Yes. You can be informed about this kind of changes over an email sent to you. In addition, there is a protocol of this sort of changes that can be seen later in the HAN-protocol view. BTW: If you have setup special accounts and you do not want any automatic changes made there, then you can block such accounts for the EJL/HAN-interface.
