Run iLO remote console from shell

README.md

iLO Remote Console

This small script lets you start iLO Java-based console from shell.

But why not HTML5?

• iLO 2/3 doesn't have HTML5 console
• Mounting local (from the client computer) ISOs is PAINFULLY slow via HTML5 client

TL;DR

If you just start it, it will ask you for everything:

% ./ilo-console.sh
Connecting to iLO 4 (set ILO_VERSION to change)
iLO Host: foo
iLO Login: bar
iLO Password:

Config

You can set the following environment variables:

• ILO_VERSION: iLO version, 2, 3, and 4 are supported
• ILO_HOST: hostname/IP of the server, optionally with port (e.g. example.com, 10.0.0.3, example.com:1234)
• ILO_LOGIN: username for iLO
• ILO_SKIP_DEFAULTS: when set to anything it will auto-assume defaults

Examples

# Just use provided values
% ILO_SKIP_DEFAULTS=1 ILO_HOST=10.0.0.3 ./ilo-console.sh
Connecting to iLO 4 (set ILO_VERSION to change)
iLO Host: 10.0.0.3
iLO Login: foo
iLO Password:

# Suggest provided values
% ILO_LOGIN=foo ./ilo-console.sh
Connecting to iLO 4 (set ILO_VERSION to change)
iLO Host: 10.0.0.3
iLO Login [foo]:
iLO Password:

# Suggested values can be changed
% ILO_LOGIN=foo ./ilo-console.sh
Connecting to iLO 4 (set ILO_VERSION to change)
iLO Host: 10.0.0.3
iLO Login [foo]: bar
iLO Password:

Wait, what about ILO_PASSWORD?!

No.
Stop creating security nightmares.

ExitException: Unable to load resource ....

If you're getting an error similar to the one below:

It means your JRE has TLSv1.1 disabled. Newer versions disable it automatically upon update. Old iLO versions (<4) cannot use TLSv1.2, so the JRE download fails.

To re-enable TLSv1.1 support open Java Control Panel (e.g. on macOS it's under  -> System Preferences -> Java). Navigate to the "Advanced" tab and check "Use TLS 1.1".

It still doesn't work!

In this case you may be having JRE which doesn't support TLSv1.1 at all. The script has an option for that too - autoproxy. To make it work you need to have mitmdump (part of mitmproxy package) and socat installed in your system.

Then run the script with ILO_AUTOPROXY=1. It will automatically:

• Setup local proxy to your iLO web ignoring ancient TLS & self-signed certificates error
• Setup local proxy for iLO remote console
• Setup local proxy for iLO virtual media connection

On my ILO2 server I get:
++ curl -fsS --insecure https://host-redacted/json/login_session --data '{"method":"login","user_login":"barryn","password":"=1-v2/c2"}'
++ sed 's/."session_key":"([a-f0-9]{32})"./\1/'
curl: (22) The requested URL returned error: 404

• ILO_SESSKEY=
• [[ -z '' ]]
• echo 'Failed to retrieve key. Wrong password or banned?'
  Failed to retrieve key. Wrong password or banned?
• exit 1

When I try to open the URL https://host-redacted/json/login_session in Firefox which I am able to use to login and access my ILO page using the URL https://host-redacted/ I also get a 404 on https://host-redacted/json/login_session but logging in to https://host-redacted/ in Firefox works fine.

Not working unfortunately..macOS
