Dear all,
I got a bit of a confusing situation with the BMC of some Intel motherboards
which we recently purchased and I am not quite sure what to make out of it.
We have install a generic user via the IPMI commands on the compute nodes and
I can access the BMC remotely, again via the IPMI
Does the BMC itself know its own hostname?

Jorg, the notes I have for setting up Intel BMCs are not of any use to you,
sorry. See below.
Regarding the PXE booting, t is easy to use the syscfg utility to print out
and to set the boot order.
But I do not think this is your problem.
Oh, I just love that hacker with the black mask on hunched over the laptop
(page 6).
That's a fail straight away. As soon as you see someone on your campus with
a black mask on you know he/she is up to no good.
Regarding separate physical IPMI networks I have seen it done both ways.

Hi Chris,
ok, you can change the 'hostname' of the BMC in the BIOS, but not in the GUI,
which I found interesting but here you go.
I changed it and I still got the same issue: I can login using the IP address
but not the hostname. Here login, with the correct credentials, will be
refused.
This sounds so much like a common JavaScript problem. I thought this might
be valuable here:
https://www.gnu.org/software/freeipmi/freeipmi-hostrange.txt
When test a JavaScript file the browser will shortcut to running the file
not the browser itself via a "server" resulting in s omething like
Jorg, this is probably veering very off topic.
Intel make available the source code for those BMC cards - which surprised
me.
I saw Redfish mentioned https://www.supermicro.com/solutions/Redfish.cfm
Maybe the Redfish standard makes the cards behave differently to old-style
BMC cards

Stu,
I gotcha. Thanks for the clarification.

Hi all,
On the subject of BMCs, in case you've not seen this & run HPE gear.

Hi John,
interesting idea, but how does it work when the IP address has not been set
yet?
Regarding hostname/IP for the GUI: see my email to Chris.
Thanks!

Jorg, recalling my experience with Intel. I did not come across the problem
with IP address versus Hostname which you have.
However I do recall that I had to configure the Admin user and the
privilege level for that user on the LAN interface. In that case the
additional BMC modules were being
Hi John,
thanks for the reply. I am aware you can install user and admin level, erm,
users on the BMC. I only install admin-level users as there is only a need for
an admin to access the BMC GUI.
However, that does not explain why the IP address is working and the hostname
is not.

Hello Jorg. As you know I have worked a lot with Supermicro machines.
I also installed Intel machines for Greenwich University, so I have
experience of setting up IPMI on them.
I will take time to try to understand your problem!
Also Intel provides excellent documentation for all its products.
Hi Tony,
nope. The GUI gives me a hostname, something like BMC23453234 and it is
greyed-out so I cannot change it. The string after BMC is basically the MAC
address without any hyphens or so.
However, given I can go to the login page and given I then get rejected by the
webserver and

For what it is worth, the source code shows the BMC card is running the
lighthttpd web server
The configuration file contains

Hi,
I am not sure why, if it is a java-script problem, it would work with the
older Supermicro nodes but not with the new Intel ones.
I got more and more the feeling it is probably a simple configuration somewhere
but we are looking at the wrong place here.
All the best
