Proxy for Server Update
Configure server programs hosted on the server computer to use proxy settings when
downloading updates from the Trend Micro ActiveUpdate server. Server programs
include the OfficeScan server and the integrated Smart Scan Server.
To configure proxy settings:
PATH: ADMINISTRATION > PROXY SETTINGS > EXTERNAL PROXY TAB
1. On the OfficeScan Server Computer Updates section, select the check box to
enable the use of a proxy server.
2. Specify the proxy protocol, server name or IP address, and port number.
3. If the proxy server requires authentication, type the user name and password in the
fields provided.
4. Click Save.
Server Component Duplication
When the latest version of a full pattern file is available for download from the Trend
Micro ActiveUpdate server, 14 "incremental patterns" also become available.
Incremental patterns are smaller versions of the full pattern file that account for the
difference between the latest and previous full pattern file versions. For example, if the
latest version is 175, incremental pattern v_173.175 contains signatures in version 175
not found in version 173 (version 173 is the previous full pattern version since pattern
numbers are released in increments of 2. Incremental pattern v_171.175 contains
signatures in version 175 not found in version 171.
To reduce network traffic generated when downloading the latest pattern, OfficeScan
performs component duplication, a component update method where the OfficeScan
server or Update Agent downloads only incremental patterns. See Update Agent
Component Duplication on page 4-42 for information on how Update Agents perform
component duplication.
