Hey.

Im trying to get the HP iLO sensor to work to no avail.
Anyone knows how to fix it?

Getting this error message:

Judging by this error message that you are receiving, the SSL setup that you are using on the server iLO is somehow not being accepted / trusted by the Python ssl library

Lars_Eriksson · June 15, 2017, 1:51pm

I kinda figured the same.

Anyone knows how to solve it?

repvik · June 15, 2017, 6:42pm

The ILO cert is probably self-signed? My guess is that you’ll have to create your own Certificate Authority, add the CA to linux’s cert store, sign a certificate, upload this to ILO.
That, or find a way to make HA tell python to ignore invalid certificates.

I’d love to hear back if you succeed, as I have two 380G7 myself. Haven’t tried adding them yet, as I struggle with basic lightning controls so far

Lars_Eriksson · June 15, 2017, 8:45pm

Yeah, its the default cert that follows iLO 3 default installation

That might be, for the moment i use a script that pulls the iLO3 information an publishes it to my MQTT server, works fine and all but it would be nice to have native functionality.

Im just moving to a DL380e Gen8 with iLO4, might work better. or not… we will see

Hi, Have you been able to get this to work? I get the same error. SSLv3 handshake error.

Max_HASS · June 5, 2018, 3:49pm

Can you share the script you are using to publish ilo data to mqtt?

Lars_Eriksson · June 11, 2018, 11:54am

No i have not been able to get it to work yet, my script does the job for now.

Sure, it uses PHP and Linux CLI software ipmitool (i guess apt-get install ipmitool if you use Ubuntu), and this MQTT class for PHP: https://github.com/bluerhinos/phpMQTT

And heres the PHP code:

Not sure if anyone is still needing this, but my ML110 was giving a similar error.
In the end I edited

/usr/src/homeassistant/homeassistant/components/hp_ilo/manifest.json

Changing the python-hpilo requirement to 4.3

I then enabled Enforce AES/3DES Encryption on ILO3.

I can’t find this file in HA-OS:2021.7.4?

my error:

Latest iLO integration already have set python-hpilo requirement to 4.3.

github.com

home-assistant/core/blob/85bcf11aeb8e7af8045ca2081411b548c8e8a7a1/homeassistant/components/hp_ilo/manifest.json

  "documentation": "https://www.home-assistant.io/integrations/hp_ilo",
  "iot_class": "local_polling",
  "requirements": ["python-hpilo==4.3"]
}

Still can’t get ilo integration to work?

dimmuboy · March 22, 2023, 10:26pm

I have same issue SSLV3_ALERT_HANDSHAKE_FAILURE because I have od iLO 2.32 and I can use only ssl.PROTOCOL_TLSv1

Edit: I found some did that but I have no idea how

github.com/seveas/python-hpilo

python-hpilo can't connect anymore to an iLO2 server on python3.10

Hello. I use Home Assistant with the python-hpilo functionality to monitor so…me old servers in a dashboard. From what I have read, the supported versions of TLS have had the defaults changed to not allow anything "worse" than TLS1.2, so the old versions of SSLv3 that iLO2 uses doesn't work anymore in python 3.10 I tried changing some options in hpilo.py to enable SSLv3 but haven't been successful thus far and I am unsure how to proceed. Home Assistant has recently bumped its python version to 3.10 and downgrading to an older version isn't really an option, because even if I did downgrade, it would only be a stop gap solution. I'm not sure how to proceed and I've tried as much as I can to figure out the problem by myself. A potential workaround I could see is running a proxy webserver to sit between the two to "upgrade" it's TLS version, but I'm not sure. I would appreciate any help that you can provide.
