Specifying the password as a command line option is not recommended.

Bridge IPMI requests to the remote target address.
-‐U

Remote server username, default is NULL user.
-‐v
Increase verbose output level. This option may be specified multiple times to increase the level of debug output.
If given three times you will get hexdumps of all incoming and outgoing packets.
-‐V
Display version information.
If no password method is specified, then
ipmitool
will prompt the user for a password. If no password is entered at the
prompt, the remote server password will default to NULL.
SECURITY
The
ipmitool
documentation highlights that there are several security issues to be considered before enabling the IPMI
LAN interface. A remote station has the ability to control a system's power state as well as being able to gather certain
platform information. To reduce vulnerability, we strongly advise that the IPMI LAN interface only be enabled in 'trusted'
environments where system security is not an issue or where there is a dedicated secure 'management network' or
access has been provided through an
console server
.
Further, we strongly advise that you do not enable IPMI for remote access without setting a password, and that that
password should not be the same as any other password on that system.
When an IPMI password is changed on a remote machine with the IPMIv1.5
lan
interface, the new password is sent
across the network as clear text. This could be observed and then used to attack the remote system. We recommend
that IPMI password management only be done over IPMIv2.0
lanplus
interface or the system interface on the local
station.
For IPMI v1.5, the maximum password length is 16 characters. Passwords longer than 16 characters will be truncated.
For IPMI v2.0, the maximum password length is 20 characters; longer passwords are truncated.
