9 Secure Shell<br />
SSH overview<br />
SSH is a Telnet-like program for logging into <strong>and</strong> executing comm<strong>and</strong>s on a remote machine,<br />
which includes security with authentication, encryption, <strong>and</strong> data integrity features. The <strong>iLO</strong> firmware<br />
can support simultaneous access from five SSH clients. After SSH is connected <strong>and</strong> authenticated,<br />
the comm<strong>and</strong> line interface is available.<br />
<strong>iLO</strong>3 supports:<br />
• SSH protocol version 2<br />
• PuTTY is a free version of the SSH protocol, <strong>and</strong> is available for download on the Internet.<br />
When using PuTTY, versions before 0.54 might display 2 line feeds instead of a single line<br />
feed when the ENTER key is pressed. To avoid this issue, <strong>and</strong> for best results, <strong>HP</strong> recommends<br />
using version 0.54 or later.<br />
• OpenSSH, which is a free version of the SSH protocol available for download on the Internet.<br />
When upgrading the firmware, a one-time 25-second delay occurs before SSH functionality is<br />
available. During this time, <strong>iLO</strong> generates the 1024-bitDSA keys. These keys are saved by <strong>iLO</strong> for<br />
future use. If <strong>iLO</strong> is reset to factory defaults, the DSA keys are erased <strong>and</strong> are regenerated on the<br />
next boot.<br />
<strong>Support</strong>ed SSH features<br />
The library supports only version 2 (SSH-2) of the protocol. Table 25 (page 136) shows the SSH<br />
features supported by <strong>iLO</strong>.<br />
