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.
ssh $ilo returns Received disconnect from ip.ad.dr.ess: 11: Authentication failed
Check if you have several ssh keys 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 ssh-agent (eg with "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. Workaround it with "unset LANG; ssh $ilo", or get and install a newer iLO firmware from the HP website.
