You want to configure your iManager to be able to access the Internet (for those plug-ins) through a proxy (such as squid or BorderManager).
1. Open imanager\bin\iManager.bat
2. Find the line that has ":DONE_VAR" in it.
3. Add the following just above that line. Obviously, replace "yourproxyipaddress" and "yourproxyport" appropriately.
set CATALINA_OPTS=%CATALINA_OPTS% -Dhttp.proxyHost=yourproxyipaddress
set CATALINA_OPTS=%CATALINA_OPTS% -Dhttp.proxyPort=yourproxyport
4. Find the line that has "start %JAVA_EXE% -Xms256m -Xmx512m" at the start and edit it to have " %CATALINA_OPTS% " between the "%JAVA_EXE%" and the "-Xms256m". The completed line should look something like this:
start %JAVA_EXE% %CATALINA_OPTS% -Xms256m -Xmx512m -Xbootclasspath/a:%BPATH% -cp
-Djava.library.path=%NATIVE_LIB_PATH%;%SWT_LIB_PATH% %DEBUG_PARAMS% %MAIN_CLASS% %1 %2 %3
%4 %5 %6 %7 %8 %9
5. Start your iManager and you'll see that it shows NPM's to download!
