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. |

Check if you have several [SSHKeys] in your [SSH] agent (eg. with "<tt>ssh-add -L</tt>"). 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: |

"<tt>ssh $ilo</tt>" returns "<tt>shell request failed on channel 0</tt>": |

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

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), you can work around this by completely unsetting the <tt>LANG</tt> EnvironmentVariable: |

Note that "<tt>LANG= ssh -v $server</tt>" only sets the variable to the empty string which your [SSH] client will still send, which is enough to confuse iLO: |
