Re: [Freeipmi-users] Send Message using FreeIPMI

[Phil_Chidester]

Hi Al,

Thanks for the quick response. I am using a similar command to yours however I 
am getting :
Unable to send command: Invalid argument

What I am doing is having two BMCs talk to each other over IPMB. Currently both 
addresses are 0x20 however.

I tried this command as well for bridging sdrs :

ipmitool -m 0x20 -t 0x20 sdr

However it just returned the host sdr not the peer sdr.

Do I need to change the address of the peer controller to something besides 
0x20 and provide a SRC Type 12 (Management Controller Device Locator Record)?

Thanks in advance,

Hi Phil,

Are you trying to program a raw command via libfreeipmi?  What problems are you 
having?

It's sort of hard to describe a raw command to do it, since one normally uses 
it to encapsulate another command for bridging, and its dependent on the 
channel and addresses you're sending to.  Here's an example of a send message, 
bridging a sensor read, on a motheboard I have.

ipmi-raw 0 6 0x34 0x06 0x2c 0x10 0xc4 0x20 0x4e 0x2d 0x1a 0x4b

Here's the packet I created it from.
