SSH overview

SSH is a telnet-like program for logging into and for executing commands on a remote machine, which includes security with authentication, encryption, and data integrity features. iLO 3 can support simultaneous access from two SSH clients. After SSH is connected and authenticated, the command line interface is available.

iLO 3 supports:

• SSH protocol version 2
• PuTTY 0.54, which is a free version of telnet and SSH protocol available for download on the Internet. When using PuTTY, versions before 0.54 might display 2 line feeds instead on a single line feed, when the ENTER key is pressed. To avoid this issue and for best results, HP recommends using version 0.54 or later.
• OpenSSH, which is a free version of the SSH protocol available for download on the Internet.

When upgrading the firmware, there is a one-time 25-minute delay before SSH functionality is available. During this time, iLO 3 generates the 1024-bit RSA and DSA keys. These keys are saved by iLO 3 for future use. If iLO 3 is reset to factory defaults, the RSA and DSA keys are erased and are regenerated on the next boot.
