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
ipmitool lan set 1 defgw ipaddr
ipmitool lan set 1 bakgw ipaddr

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:

/admin1-> console com2

Escape from the console with ^\

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