For a r4xx version Dell server with an iDrac6 Express controller installed.
o configure the ip interface
o configure the admin user
o test a serial console connection

To enable the ipmitool on the host server:


modprobe ipmi_msghandler
modprobe ipmi_devintf
modprobe ipmi_si

Then configure the ip info for the iDrac:


ipmitool lan set 1 netmask 255.255.255.0
ipmitool lan set 1 defgw ipaddr 192.168.1.1
ipmitool lan set 1 bakgw ipaddr 192.168.1.2

Then configure a basic user on the system:


sudo ipmitool user list 1
sudo ipmitool user set password 2

SSH should be accessible now on the iDrac, ssh in and start a console on serial1:


ssh
/admin1-> console com2

Escape from the console with ^\

be sure to also configure the getty on the host server too.
