Using LO100

Using SSL

SSL is a protocol used to transmit private documents through the Internet and uses a private key or
certificate to encrypt data transferred over the SSL connection. The Lights-Out 100 provides security for
remote management in distributed IT environments by using an industry-standard encryption protocol for
data traveling on unsecured networks.
SSL is available by installing the Lights-Out 100c Remote Management Card or purchasing the Lights-Out
100i Select Pack or the Lights-Out 100i Advanced Pack. For more information, see "LO100 optional
features (on page

6

)."

LO100 comes preinstalled with a certificate. To install a user-specific certificate, see the one-time
"Importing a certificate (on page

56

)" setup procedure.

If you cannot access the login page, you must verify the SSL encryption level of your browser is set to 128
bits. The SSL encryption level within the management processor is set to 128 bits and cannot be changed.
The browser and management processor encryption levels must be the same.
To use the preinstalled certificate, enter https://ipaddress in the address line of the browser, which

uses SSL-encrypted communication. Enter http://ipaddress to use non-SSL encrypted communication.

Using SSH

SSH is a telnet-like program for logging in to and executing commands on a remote machine, which
includes security with authentication, encryption, and data integrity features. The Lights-Out 100 remote
management processor can support simultaneous access from two SSH clients. After SSH is connected
and authenticated, the command line interface is available. LO100 supports two simultaneous SSH
connections.
SSH is available by installing the Lights-Out 100c Remote Management Card or purchasing the Lights-Out
100i Select Pack or the Lights-Out 100i Advanced Pack. For more information, see "LO100 optional
features (on page

6

)."

LO100 supports the SSH version 2 and the following client utilities:

PuTTY 0.54 or later.

OpenSSH

LO100 comes preinstalled with a certificate. To install a user-specific certificate, see the one-time
"Importing a certificate (on page

56

)" setup procedure.

Using the SSH utility

When using a SSH utility to connect to a server for the first time, the utility prompts you to accept the
server public key, sometimes referred to as a host key. Accepting this key authorizes the utility to store a
copy of the public key in its own database. The utility recognizes the server when future connections are
attempted by comparing the public key to the one stored in its database.
