This type of configuration is when no proxy is required to connect to the
Internet. It means the application can connect directly to the Lenovo Help Center
servers.
EasyUpdate and Update Retriever support two types of proxies: HTTP proxy
and SOCKS proxy.
– Connection through an HTTP proxy -
In this type of configuration, EasyUpdate and Update Retriever connect to an
HTTP proxy server to access the Internet. Then the proxy server connects to
the Lenovo Help Center.
Note: HTTP basic and NTLM 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 each client to authenticate 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 uses the Login dialog whenever the HTTP
and proxy Authenticator needs the end user to provide a user name and
password in order to connect successfully to the Proxy server. SOCKS
authentication is not supported.
– Connection through a SOCKS proxy -
In this type of configuration, EasyUpdate 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.
