Common Access Problems
|
|
|
|
The most common access problems result in being prompted for authentication, inability to reach the authentication page itself, or receiving a message that collections are not authorized.
|
|
|
|
Incorrect or incomplete IP address ranges specified.
|
|
|
|
Double-check that your subscription manager includes the full list for your campus or institution. An IP address is made up of four numbers separated by three periods
The best way to supply IP address ranges is to use the CIDR format, e.g. 123.23.0.0/17. This format is compact, unambiguous, and globally recognized by network administrators.
A common alternative format which many find more intuitive is to use dashes and/or asterisks, e.g. 123.23.0-127.* (which is equivalent to the example above).

|
Incorrect proxy server configuration.
|
|
|
|
If your campus uses a proxy server, it generally needs to be configured with the host name and/or domain of our server. These are:
|
|
llmc.com
|
|
In addition, users at your campus or institution need to access the service via a connection through your proxy server, not directly. Your proxy server administrator can provide you with a proper URL for linking to our service; ensure that your users are entering via that URL.
|
|
|
|
Firewall configuration.
|
|
|
|
Access problems relating to firewalls can manifest themselves in a number of ways. If your network environment is firewalled, consult your firewall administrator to ensure that access to our service will not be blocked. Be prepared to share the URLs you use for access, and tell the firewall administrator that our services run on the standard HTTP ports 80 and 443.One emerging problem area is with NAT firewall routers, which are commonly used with ADSL and cable modem connections. These devices provide IP addresses to the workstations in the office or home network (typically 192.168.0.0/16 or some subset of that), but appear on the Internet with a different “external” IP address. For access to work, the external IP address(es) must be static, which is an arrangement you must make with your ISP, and must be supplied to your subscription manager. The internal IP addresses are irrelevant in this environment.
