To access the internet and reach the Symantec LiveUpdate servers you have to configure a proxy server.
The proxy settings need to be configured in 2 locations on the DCS Manager machine:
1- To download Titanium information, SymEFA and Revocation lists:
Browse to <Server installation folder>\liveupdate
and start command prompt.
"..\jre\bin\java.exe" -classpath jlu.jar com.symantec.liveupdate.config.editor.ConfEditor
A new dialog box opens.
In the dialog box, add a new property as:
Property name: proxy.
Property value: proxyhost:proxyport.
Click Ok
Click Save
2 - To download Reputation Data:
Go to <Server installation folder>\Symantec\Data Center Security Server\Server\tomcat\conf\
Edit sis-server.properties
Add the following lines (they are already present but commented out with #)
sisserver.http.proxyset=true
sisserver.http.proxyhost=192.168.2.2
sisserver.http.proxyport=3128
Save and exit.
