UNIX-Style Directory Listings

To configure Auto Update using an FTP server, the FTP server must provide directory listing responses
in UNIX style. MS-DOS style directory listing is not supported by the sensor Auto Update feature.

Increasing the Memory Size of the Java Plug-In

To correctly run IDM, your browser must have Java Plug-in 1.4.2 or 1.5 installed. By default the Java
Plug-in allocates 64 MB of memory to IDM and ASDM. IDM and ASDM can run out of memory while
in use, which can cause IDM and ASDM to freeze or display blank screens. Running out of memory can
also occur when you click Refresh. An
whenever this occurs.
You must change the memory settings of Java Plug-in before using IDM and ASDM. The mandatory
minimum memory size is 256 MB.
