Chapter 3. Configurations This chapter provides you with conceptual information and procedures to configure connectivity settings, repository locations, and the user interface. Connection configurations System Update and Update Retriever support three types of connectivity configuration: direct connection, static proxy connection, and automatic configuration script. • Direct connection This type of configuration is used when no proxy is required to connect to the Internet. It means the application can connect directly to the Lenovo Help Center servers. • Static proxy connection System Update and Update Retriever support two types of proxies, HTTP (Hypertext Transfer Protocol) proxy and SOCKS (Socket Security) proxy. - Connection through HTTP proxy In this type of configuration, System Update and Update Retriever connect to an HTTP proxy server to access the Internet. The proxy server connects to the Lenovo Help Center. Note: HTTP basic and NTLM (NT LAN Manager) authentications are supported. The following elements are obtained from the system configuration: - Proxy server name or IP address - Proxy server port The proxy server might require to authenticate each client before it can be granted access to the Internet. In that case, the end user must additionally provide a user name and password. The user name and password values can be set for the end user by the administrator. The HTTP proxy authenticator, an integrated component in System Update, displays a logon dialog whenever System Update detects that the HTTP proxy server needs the end user to provide a user name and password in order to successfully connect to the proxy serve. After providing the correct user name and password, the end user will be authenticated to connect to the HTTP proxy server. SOCKS authentication is not supported. - Connection through a SOCKS proxy In this type of configuration, System Update and Update Retriever connect to a SOCKS server and then the SOCKS server connects to the Lenovo Help Center. The following elements must be configured: - Server name or IP address - Server port Note: Only SOCKS 4 without authentication is supported. • Automatic configuration script By enabling Use automatic configuration script in the Internet Explorer® Web browser, System Update and Update Retriever can access the Internet according to the automatic configuration script file. Configuring System Update Configurations for System Update can be done through the registry, Active Directory®, or the start.reg file. If you are configuring just one system, you can use the registry to configure System Update. If you © Copyright Lenovo 2009, 2014 15
