iLO - Integrated Lights Out

iLO is the management interface used on many HewlettPackard servers. These often allow you to remotely power a machine up or down, and connect to the machine's local console.

Random Notes

"ssh $ilo" returns "Received disconnect from ip.ad.dr.ess: 11: Authentication failed"

Check if you have several SSHKeys in your SSH agent (eg. with "ssh-add -L"). Each time your agent tries a key that is not in the iLO's list of authorised keys counts as a failure, and after 3 failures it will close the connection. Either install your keys in the iLO's key management system, or run SSH without your agent:

SSH_AUTH_SOCK= ssh $ilo
"ssh $ilo" returns "shell request failed on channel 0"

If you run "ssh -v $ilo", you'll see that the last debug message before failing is something like

debug1: Sending env LANG = en_NZ.UTF-8

This confuses old versions of the iLO. If you don't want to install a newer iLO firmware (you can get it from the HP website), work around it with

LANG= ssh $ilo
