User Guide - Kaspersky Lab

ADVANCED OPTIONS 267
Automatically detect the proxy server settings. If this option is
selected, proxy server settings are autodetected using the WPAD
(Web Proxy Auto-Discovery Protocol) protocol. If the above
protocol is unable to determine the address, Kaspersky Internet
Security uses the proxy server settings specified for Microsoft
Internet Explorer.
Use specified proxy server settings: use a proxy server other than
the one specified in the browser connection settings. Enter an IP
address or a domain name in the Address field and a proxy server
port number in the Port field.
Not to use a proxy server for updates from local or network directories,
check Bypass proxy server for local addresses.
• Specify whether the proxy server uses authentication. Authentication is a
procedure to verify user account information for the purposes of access
control.
If authentication is required to connect to the proxy server, check Use
authentification and enter user name and password in the appropriate
fields. This will result in an attempt to perform an NTLM-authorization
followed by a BASIC authorization.
If the check box is unchecked, NTLM authorization will be attempted
using the login under which the task (such as an update, cf. Section 6.6,
p. 67) is running.
If the proxy server required authorization, and user name and password
are not specified or rejected by the proxy for whatever reason, a dialog
requesting user name and password will be displayed. If authorization is
successful, the specified user name and password will be remembered
for subsequent use. Otherwise, authorization information will be
requested again.
If an ftp server is used to update, a passive connection to the server is
established by default. If this connection attempt returns an error, an attempt is
made to establish an active connection.
By default, the update server connection timeout is 1 minute. If connection fails,
an attempt will be made to connect to the next update server once this timeout
expires. This enumeration continues until a connection is successfully
established or until all available update servers are enumerated.
