Re: [Freeipmi-devel] About KCS driver

Hi

Thanks for the advice. I realized i did a silly
mistake of using 0x0F  and instead of 0x07 - as the
LAN channel number. And it worked :-)


Like i mentioned about bmc-config (by mistake i had
typed bmc-info in my last email) , when i executed
"bmc-config --checkout" - it gave me a complete
listing of BMC config but IP address was still
0.0.0.0.
But using the client app i was able to get/set the
required BMC address.

Thanks
biju
