ipmitool - utility for controlling IPMI-enabled devices


Easy way:

yum install ipmitool
apt-get install ipmitool

Harder way (source code): (

yum install gcc make compat-glibc-headers
tar -jvxf ipmitool-1.8.14.tar.bz2
make clean
make && make install

Load kernel module:

modprobe ipmi_devintf    # CentOS 6.5 module name


Sensor Data

sdr command - Print Sensor Data Repository entries and readings

# ipmitool sdr
P0 Temp          | 36 degrees C      | ok
P1 Temp          | 36 degrees C      | ok
P0 TjMax         | 86 degrees C      | ok
P1 Tjmax         | 86 degrees C      | ok

sensor command - Print detailed sensor information

# ipmitool sensor
P0 Temp          | 37.000     | degrees C  | ok    | na        | na        | na        | na        | 84.000    | na
P1 Temp          | 36.000     | degrees C  | ok    | na        | na        | na        | na        | 84.000    | na
P0 TjMax         | 86.000     | degrees C  | ok    | na        | na        | na        | na        | na        | na
P1 Tjmax         | 86.000     | degrees C  | ok    | na        | na        | na        | na        | na        | na

Control Remote BMC

ipmitool -I lanplus -H [BMC_ADDRESS] -U USERID -P [PASSWORD] sensor

Note, my configuration was incorrect and this would timeout:

# ipmitool -I lanplus -H i-myserver -U USERID -P mypassword sensor
Error: Unable to establish IPMI v2 / RMCP+ session
Get Device ID command failed
Unable to open SDR for reading

i2c access

If you know the bus and address of a target i2c device: (server/device specific)

usage: i2c [bus=public|# [chan=#] <i2caddr> <read bytes> [write data]

Example: (temperature sensor, there is a conversion required to get to C)

# ipmitool i2c bus=1 0x3e 1 1

User List

ipmitool user list [CHANNEL_NUMBER]
# ipmitool user list 1
ID  Name             Callin  Link Auth  IPMI Msg   Channel Priv Limit
