I *think* I see how it works. Like this, right?
ipmi_sim_lancontrol get name1 name2 ...
prints:
name1: val1\n
name2: val2\n
...
ipmi_sim_lancontrol set name1 val1 name2 val2 ...
I'll do some debugging and get teh values. That's for getting and setting
the properties of the interface that ipmi_sim is listening on, right?
Right now I'm stuck on this:
sudo ipmi_sim -d -c lan-ipmi1.conf
IPMI Simulator version 1.0.13
No bmc_ipmb specified or configured.
Here's my config. Where does "bmc_ipmb" go?
name "ipmi1"
set_working_mc 0x20
startlan 1
addr :: 9001
priv_limit admin
allowed_auths_callback none md2 md5 straight
allowed_auths_user none md2 md5 straight
allowed_auths_operator none md2 md5 straight
allowed_auths_admin none md2 md5 straight
guid a123456789abcdefa123456789abcdef
lan_config_program "./ipmi_sim_lancontrol ipmi1"
endlan
serial 15 localhost 9011 codec VM
startcmd "/home/noel/local/usr/bin/qemu-system-x86_64 --enable-kvm
