[Linux-cluster] ipmi activates session, but no talk.

[Emmanuel Thomé]

Hi.

I'm trying to set up ipmi (1.5) management using the bmc on ibm
eserver326 machines. Yes, these machines are old.

So far, I've been able to access the bmc with ipmitool, and configure it
as correctly as I could for remote access.

When trying to access it from afar, I successfully activate a session,
but further requests are unanswered.

Some dumps of ipmitool commands are included below.

If anybody has an idea of what's going on, that would be greatly
appreciated.

I might also try to flash the bmc firmware, as it seems that ibm released
a newer firmware for these servers. But I'm already a bit puzzled by
the situation so far.

Thanks,

E.

I'm trying to access the bmc with IP 152.81.4.81 from the host with IP
152.81.3.83. The BMC piggies-back on the eth0 NIC which has IP
152.81.3.81 for the system. Thus the BMC and the system both have
different MAC and IPs. Seems to work fine as some kind of conversation
occurs.

Here's the output of a remote ipmi request:

On the machine I'm trying to talk to, I have in particular:
