Server User Manual

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.
