KeyError: 'transfer-encoding'

I'm seeing this error message when trying to talk to a iLo3 on a rx2800 i2

You left your password in there. I edited it out, but you may want to change that password 😞

02.01.03 is not a known version number, are you sure this is an ilo? If you change line 509 to if header.get('transfer-encoding', '') == 'chunked': it should get beyond this point, but given that it's behaving quite differently from what I know, I don't know how far it will get.

According to HPSC iLO-3 Firmware Version: 02.01.03 is the most recent version for this server. HPE Integrity Servers are not so common so may be few have tried this.

[ although this iLo is not accessible from anywhere outside of a firewalled LAN it was silly of me to include the password and I have changed it ].

I would be disappointed but not entirely surprised to discover this server iLo is too prehistoric for this software

Heh, python-hpilo still supports the original ilo 1. But yeah, I only ever use(d) it on proliants, not integrity servers. It looks like the protocol autodetection thinks you should be using http to talk to the ilo, but actually doing this fails and you get some html document back. Can you try with --protocol raw ?

I guess the key part of that response is at the end "The requested method is not recognized by this server." Any thoughts on how to find out what methods are available ?
