SSH overview

SSH is an advanced feature that is available on ProLiant ML150 G2 and ProLiant ML110 G3 servers by installing the Lights-Out 100 Remote Management Card, or on ProLiant DL140 G2 servers and ProLiant DL145 G2 servers by purchasing the Lights-Out 100i Select Pack or the Lights-Out 100i Advanced Pack.

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 the following protocols:

•SSH protocol version 2

•PuTTY 0.54, which is a free version of telnet and SSH protocols available for download on the Internet. When using PuTTY, versions earlier than 0.54 might display two line feeds instead on a single line feed, when the Enter key is pressed. To avoid this issue, and for best results, use version 0.54 or later.

•OpenSSH, which is a free version of the SSH protocol available for download on the Internet.

NOTE: Logging in to an SSH session could take up to 90 seconds. Depending on the client used, you might not see on-screen activity during this time.

LO100 comes preinstalled with a certificate. To install a user-specific certificate, see the one-time "Importing a certificate (on page 21)" setup procedure.

Using SSH

When using a Secure Shell utility to connect to a server for the first time, the utility will prompt you to accept the server's 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 will automatically recognize the server when future connections are attempted, by comparing the public key to the one stored in its database.

To access the remote management processor using SSH:

1.Open an SSH window.

2.When prompted, enter the IP address or DNS name, login name, and password.

Using OpenSSH

To start an OpenSSH client in Linux, use:

ssh -l loginname ipaddress/dns name

Using PuTTY

•To start a PuTTY session, double-click the PuTTY icon in the directory in which PuTTY is installed.

•To start a PuTTY session from the command line:

oTo start a connection to a server called host:

putty.exe [-ssh -telnet -rlogin -raw] [user@]host

oFor telnet sessions, the following alternative syntax is supported: putty.exe telnet://host[:port]/

oTo start an existing saved session called sessionname:
