Hi,

I have an (old) SMC-001 IPMI device on an (old) X6DVL-EG2 motherboard. My problem is that I cannot access the BMC from LAN. I'm also getting some interesting output from ipmitool.

First, the setup. I enable Console Redirection in the BIOS, turn BIOS Redirection after POSt to "disabled". I then modprobe'ed for ipmi_msghandler, ipmi_devintf and ipmi_si. I then found ipmi0 under /dev. So far so good. Since I want console redirection over serial, I modified /boot/grub/menu.lst:

I then modified "/etc/inittab" as follows:

S1:12345:respawn:/sbin/agetty -L 19200 ttyS1 ansi

Networking I set as following, using "ipmitool"

ipaddr:  192.168.3.164
netmask:  255.255.255.0
defgw:  192.168.3.1

The above are correct for my environment.

To test it I do:

ipmitool -I open chassis power off

which responds by powering off the machine.

When I to access from another computer on the network, however, I get an error message:

host# ipmitool -I lanplus -H 192.168.10.164 -U Admin -a chassis power status
Error: Unable to establish LAN session
Unable to get Chassis Power Status

"Admin" seems to be a valid user name:

host# ipmitool -I open user list 1
2   Admin            true    false      true       USER

The interesting output from ipmitool I initially mentioned:

host # ipmitool -I open lan set 1 access on
Set Channel Access for channel 1 failed: Request data field length limit exceeded

Also,

newload4:/home/gjones # ipmitool channel info 1
Channel 0x1 info:
Channel Medium Type   : 802.3 LAN
Channel Protocol Type : IPMB-1.0
Session Support       : session-less
Active Session Count  : 0
Protocol Vendor ID    : 7154
Get Channel Access (volatile) failed: Request data field length limit exceeded

The output of "ipmitool -I open lan print 1" is here:

Any help/suggestions is greatly appreciated; I've been working with this thing for a few hours now with no success.
