IPMI ueber LAN auf Dell PowerEdge 2950 mit Ubuntu

Ich sitze hier gerade an einem Dell PowerEdge Server und versuche krampfhaft den Zugriff auf IPMI ueber LAN einzurichten. Allerdings musste ich feststellen, dass das zum Einrichten des LAN-Devices notwendige Skript (bmcautoconf.sh) nirgends zu finden ist. Weiss evtl. jemand die Befehlsfolge, die durch dieses Skript ausgefuehrt wird oder kann mir ein entsprechendes Skript zukommen lassen? Das IPMI ist soweit eingerichtet und funktioniert auch (siehe http://poweredge.blog.de/ ) nur der Zugriff uebers LAN will halt nicht so, wie er soll.

Code:
root@traumato:~# IPMI_PASSWORD=meinpasswort ipmitool -I lan -H localhost -E chassis status
Error: Unable to establish LAN session
ipmi_lan_send_cmd failed to open intf
Error sending Chassis Status command

Die selbe Meldung bekomme ich auch, wenn ich Remote von meiner Workstation einen Zugriff versuche. Bei mir laeuft ipmitool 1.8.7 und OpenIPMI 2.0.7.

Edit: Auch ein zweites Problem ist mir gerade noch aufgefallen:

Code:
root@traumato:/home/blogde# ipmitool -I open chassis power diag
Chassis Power Control: Diag

traumato kernel: [  291.961538] Uhhuh. NMI received for unknown reason 21 on CPU 0.

traumato kernel: [  291.996978] Do you have a strange power saving mode enabled?

Message from syslogd@traumato at Fri Jul 20 14:50:36 2007 ...
traumato kernel: [  292.030836] Dazed and confused, but trying to continue

Jemand eine Idee, woran das liegen koennte? Ein Energiesparmodus ist naemlich garnicht eingestellt.
 
Zuletzt bearbeitet:
Ich weiß nicht ob das hilft, aber ich habe hier noch ein bmcautoconf.sh file.

Zum zweiten Problem: Kann es sein dass das am RAM liegt? Meine ich irgendwo mal gelesen zu haben. Oder vielleicht an der Kühlung des Gerätes.

# specify network settings on the command line.
#
# If the wrong channel is used you could lose network access to the
# box because your BMC will be sending out bad Gratuitous ARP packets
# with the wrong MAC address. You will need to use a console or
# override your local ARP cache with the correct addr.

Danke für das Skript. Werde es mal damit probieren. Wie mir der Dell-Support mitteilte liegt Problem Nummer 2 wohl daran, dass der IPMI-Kram bei Ubuntu derzeit nur auf IBM-Maschinen fehlerfrei funktioniert. Ubuntu und Dell sind da aber schon in Verhandlung, so dass zu hoffen bleibt, dass in nächster Zeit auch die IPMI-Unterstützung für Dell-Server besser funktionieren wird.
 
Unter Debian dürfte das /usr/share/ipmitool/bmclanconf sein ...
