-p <port>
Remote server UDP port to connect to. Default is 623.
-P <password>
Remote server password is specified on the command line. If supported, it will be obscured in the process list.
Note! Specifying the password as a command line option is not recommended.
-t <target_address>
Bridge IPMI requests to the remote target address.
-U <username>
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 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.
