Reset a BMC User Password from Windows or Linux

This translates the source’s local, in-band IPMI procedure. It assumes authorized operating-system access and the correct IPMI driver/interface. Identify the actual account ID before changing a password; the example admin ID1 is not guaranteed on every BMC. Literal example passwords are replaced with placeholders.

Windows example

1. If the required IPMI driver is not installed, the source supplies IPMIToolWin.zip and runs its getlog.bat installer. This is the source’s legacy package, not a verified current driver for every Windows/server version; obtain and inspect the compatible vendor package.
2. Open Command Prompt, enter the package’s ipmitool directory and list users on the indicated channel:

ipmitool user list 1

Source example output:

ID  Name     Callin  Link Auth  IPMI Msg  Channel Priv Limit
1   admin    false   true       true      ADMINISTRATOR
2   default  true    false      false     NO ACCESS

Set the password for the verified account:

ipmitool user set password 1 <NEW_PASSWORD>

Linux example

The source links ipmitool-1.8.18.tar.gz.zip and illustrates a source build:

The image uses chmod 777 configure; broad world-write permission is unnecessary for making a script executable. Prefer the distribution’s compatible package or a reviewed build process; if building, use appropriate permissions such as chmod +x configure. make install changes system software, so use the intended prefix/privileges.

For the source’s local IPMI device access:

modprobe ipmi_devintf
modprobe ipmi_si
ipmitool user list 1

The source shows the same two-user table as above. Confirm the actual admin user ID, then:

ipmitool user set password 1 <NEW_PASSWORD>

Replace the placeholder with a password meeting the BMC’s supported length/complexity rules. Command-line password arguments may be exposed in process/history records; follow the platform’s approved credential-handling method. Verify access with the intended account and avoid assuming that local IPMI is available under every firmware lockdown policy.
