Is it possible to reset the password on a SuperMicro IPMI interface?

Question

Is it possible to reset the password on a SuperMicro IPMI interface? My motherboard is model X8STI-F.

If you access it locally you can specify a new password. On Linux this would be done via ipmitool. Something like this should work:

ipmitool -I open lan set 1 password NEWPASSWORD

If you don't know which channel is your ethernet interface, just page through them one at at time, like so:

# ipmitool -I open channel info 1
Channel 0x1 info:
  Channel Medium Type   : 802.3 LAN
  Channel Protocol Type : IPMB-1.0
  Session Support       : multi-session
  Active Session Count  : 0
  Protocol Vendor ID    : 7154
  Volatile(active) Settings
    Alerting            : disabled
    Per-message Auth    : disabled
    User Level Auth     : enabled
    Access Mode         : always available
  Non-Volatile Settings
    Alerting            : disabled
    Per-message Auth    : disabled
    User Level Auth     : enabled
    Access Mode         : always available

Note that the medium type is "802.3 LAN". That's the one you want. Other channels may look like this:

# ipmitool -I open channel info 2
Channel 0x2 info:
  Channel Medium Type   : Serial/Modem
  Channel Protocol Type : IPMB-1.0
  Session Support       : single-session
  Active Session Count  : 0
  Protocol Vendor ID    : 7154
# ipmitool -I open channel info 3
Channel 0x3 info:
  Channel Medium Type   : System Interface
  Channel Protocol Type : KCS
  Session Support       : session-less
  Active Session Count  : 0
  Protocol Vendor ID    : 7154

I just had to deal with this same issue yesterday, I was not able to log into my SuperMicro IPMI web interface because I had not used it frequently and forgot the password. The command in Insyte's answer did not work for me but it was close. This command worked to reset the ADMIN account's password:

ipmitool -I open user set password 2 ADMIN

The number 2 there is the user id. The ADMIN account defaults to user id 2. So I'm setting user id 2's password to ADMIN which is the default, but you could put any other password there.

Thank you to Insyte for pointing me on the right track of using ipmitool, after a few searches online I was able to find this working command. Hopefully it will help someone else that stumbles on this question.

Best way is to reset to defaults with SuperMicro native tool, like so:

./ipmicfg-linux.x86_64 -fd

(All this may take a few seconds to take effect, so wait between commands!)

Now turn off the default on DHCP restored from factory defaults with

./ipmicfg-linux.x86_64 -dhcp off

then, restore your network settings with:

./ipmicfg-linux.x86_64 -m $IP_ADDRESS
./ipmicfg-linux.x86_64 -k $NETMASK
./ipmicfg-linux.x86_64 -g $GATEWAY_IP

You'll have to configure the IP/Netmask/Gateway again with the same tool, but this is the only way I could make it work.
OpenIPMI and IPMITools did not work for me on Debian Squeeze. I've tried resetting the password, cold resetting BMC, to no avail. However, they are good for setting IP and reading sensor data.

You can get the appropriate version for your OS from SuperMicro FTP:

If you rarely use the IPMI interface it's possible it's still using the default username/password ADMIN/ADMIN (case sensitive).
