Introduction – IP Ranges

The IP Addresses page allows administrators to assign default profiles to unsigned users that access the MetaLib User Interface (/V). For example, users that access the UI from within the campus network receive a default profile of <Portal>-<LNG>-IN, while others receive the profile <Portal>-<LNG>-GUEST.

This page contains the following sections:•Create a New IP Range — allows you to add a new IP range for the specified institution•List of Defined IPs — displays the list of IP ranges that are defined for the specified institution

In addition, you can perform the following actions on each IP range:<E> — Modifying an IP Range <D> — Deleting an IP Range

•Select an Institution from the drop‐down menu on the IP Addresses page •In the Create a New IP Range section, use table below to enter the fields•Click SUBMIT to create the IP range •The new IP range displays in the List of Defined IPs section

IP Range This field defines the start and end IP address of the IP range. The following rules apply to IP ranges.Each IP address must be of the following format, where <nnn> is 0 to 255: <nnn>-<nnn>-<nnn>-<nnn>An IP range cannot overlap an address of another IP range.

Default Profile

This field assigns the default profile to the IP range.

Proxy This field indicates whether a proxy server is used for the range of IP addresses. Select one of the following options: No Need for ProxyUse Proxy Server

Institutions with proxy servers can configure their proxy servers to work with MetaLib via the Management Interface. Proxy servers are used in the following ways: •To link to the native interface of resources using HTTP access•For MetaLib searches in remote resources

From the Proxy Management screen , you can perform the following actions: •Add a new proxy by clicking the ADD PROXY button, which displays the Proxy Details page•Edit an existing proxy by clicking the E button next to the proxy that you want to modify•Delete a proxy by clicking the D button next to the proxy that you want to delete

MetaLib IP Ranges / Proxy ServersConfiguring Proxy Servers

MetaLib supports the use of proxy servers for the following purposes:•To allow users to link from MetaLib to the native interface of resources via the institutional proxy server. This means that MetaLib forwards URLs to the siteʹs proxy server so the proxy server can redirect them to the target resource

•For performing MetaLib searches via a local proxy server. This is especially important in a consortia environment, where the MetaLib server is located in one of the institutions of the consortia. In such cases, searches can be channeled via the relevant local institutional proxy server, enabling vendors to identify the institution from which searches are performed. Use of a proxy server for the link‐to‐native interface purpose can be controlled at the resource level by setting the proxy server flag in the IRD record and also by IP ranges. The use of a proxy server for search purposes can be controlled only at the resource level.

NOTE: The use of the search proxy server in MetaLib is supported for the HTTP based resources only.

Configuring Proxy Servers - Parameters

16

For each proxy, add the following parameters if they apply to your configuration: •Status ‐ A/I (Active / Inactive)•Used for ‐ Link to Native or Search•Type ‐ EZPROXY, EZPROXY‐SSO, EZPROXY‐TICKET, WAM, and SQUID•Filters ‐ IRD_SELECTIVE, IP_SELECTIVE, and LOCK (see slide 17)•Hostname:Port ‐ Maximum length 200 characters•Username ‐ Used for EZPROXY•Password ‐ Used for EZPROXY•Verification ‐ Verification of the password parameter•Notes ‐ Maximum length 200 characters


Configuring Proxy Servers - Filters

17

IRD_SELECTIVE: The proxy server should be used selectively. In this case, the system checks the flag in each IRD record to determine if the proxy should be used. The proxy server is used only if the Proxy Server Flag is set to Y in the resourceʹs IRD record for link to native interface using the proxy server, or if the Search Proxy Server Flag is set to Y in the resourceʹs IRD record for search using the proxy server. IP_SELECTIVE (used only for Link to Native proxies) This indicates that the proxy server is used selectively. The system checks the IP of the user. The proxy server is used only if the user is outside the IP ranges defined in the ./vir00/tab/ proxy_<institution>.config table. LOCK (used only for Link to Native proxies) This indicates that the users should be directed to the proxy server for the resources they are authorized to use.
