Again Thanks Corey,
Now I am able to receive the responses properly. But sometimes I didn't get
the responses. Same timeout error is in output. Do I need to follow any
collision detection mechanism.
Also If I replaced the slave address as 0x20 (BMC ipmb address) with the net
function 0x0a and command 0x10 to fetch the FRU info from the BMC, I am
getting the same timeout error. Do u have any idea whts the problem with
this.
ipmb_addr.addr_type = IPMI_IPMB_ADDR_TYPE;
ipmb_addr.channel = 0;
ipmb_addr.slave_addr = 0x20; // BMC IPMB address
ipmb_addr.lun = 0x00;
req.addr = (unsigned char*)&ipmb_addr;
req.addr_len = sizeof(ipmb_addr);
req.msgid = 1;
req.msg.netfn = 0x0a; // storage net function
req.msg.cmd = 0x10; //fru info command

Oops, the identifier is required for 0x2c netfns, it is one byte and is zero
for PICMG.
Can you get the errno on a failure? Perhaps you are not initializing a data
item.
