discovered using SNMP will report physical processors, and the
systems discovered using CIM will report logical processors.
* IT Assistant can receive and process alerts from systems with IPv4
address format.

Software Updates
---------------------------------------------------------------------
NOTE: IT Assistant does not support the software update task on the
management station. This is because a software update may require a
reboot that may affect other scheduled tasks that are run on the
management station. You can perform software updates using the
"Dell Systems Management Tools and Documentation" DVD after closing
the IT Assistant application.

Software Updates for Linux
---------------------------------------------------------------------
To perform a remote Linux software update, IT Assistant uses Plink
for SSH communication. By default, IT Assistant passes your
password as a command-line parameter to Plink.
NOTE: This occurs only on the IT Assistant management station.
Passwords are always encrypted when transferred to the managed
system.
If passing passwords through the command line on the IT Assistant
management station is of concern, you can configure the updates to
use RSA keys instead of passwords. A blank password in IT Assistant
will trigger SSH authentication using the RSA keys.
To create RSA keys, perform the following steps:
NOTE: It is assumed that you are running an SSH2 server and are using
the RSA2 keys.
1. Run PuTTYgen (or your preferred mechanism) for generating public/
private key pairs. You can save your private keys (".ppk" files)
to any location on your system.
The following is a sample public key that you would put in a file
that you create called "authorized_keys2 for RSA2 keys."

Linux ships with other utilities for creating public/private key
pairs. You can download PuTTYgen from the following Web address:
