IPMI Tools

There are 4 notable ipmi sw tools and here is the compare ipmi tools compare

Usage EX:
Get sensors

  • ipmi-sensors -h 10.250.210.139 -u admin -p password -D LAN_2_0

  • ipmitool -I lanplus -U admin -P password -H 10.250.210.13 sdr list

  • ipmiutil sensor -c -F lan2 -N 10.250.210.13 -U admin -R password

How to build the reusable library of ipmitool…

  1. doenload ipmitool 1.8.15

  2. yum install openssl openssl-devel (For “lanplus : yes”)

  3. cd ipmitool 1.8.15 & CC=gcc4 CFLAGS=-m32 LDFLAGS=-static & ./configure

  4. (make clean) & make & make install

  5. cd src

  6. /bin/sh ../libtool –silent –tag=CC –mode=link gcc -fno-strict-aliasing -Wreturn-type -all-static -o ipmitool.a ipmishell.o ../lib/libipmitool.la plugins/libintf.la

  7. gcc -g -lm -lcrypto ipmitool.c -fPIC -shared -o libicdcipmi.so -L. ipmitool.a -I./ipmitool-1.8.15/include/

Build own libicdcipmi.so using ipmitool.a

ipmitool.c

8.cp libicdcipmi.so /usr/lib & ldconfig

9.go build icdc_ipmi.go
