The Intelligent Platform Management Interface (IPMI) specification is an Intel led standard which defines a set of common interfaces to a computer system which system administrators can use to monitor system health and manage the system.

DELL PE sc1435 have Standard Baseboard Management Controller with IPMI 2.0 support,so we can use this feature to manage our servers .

IPMItool is a command line utility for managing and configuring systems with IPMI support. This tool allows you the ability to communicate directly with the IPMI card installed in the server or over a network using TCP/IP.

First , Power On PowerEdge sc1435 server ,when BIOS check , input Ctrl-E to keyboard:

then configure IMPI to the server, and also you can refer this guide document:
http://www.dell.com/downloads/global/power/ps4q04-20040204-Murphy.pdf

then,start OS(Debian Lenny 5.0.3 amd64)

#apt-get install ipmitool

#apt-get install openipmi libopenipmi-dev

# modprobe ipmi_watchdog
# modprobe ipmi_poweroff
# modprobe ipmi_devintf
# modprobe ipmi_si
# modprobe ipmi_msghandler

Check if ipmi_xxx related kernel modules have loaded or not:

# lsmod |grep ipmi
ipmi_si 43628 2
ipmi_devintf 13200 0
ipmi_poweroff 13776 0
ipmi_watchdog 22896 0
ipmi_msghandler 38520 4 ipmi_si,ipmi_devintf,ipmi_poweroff,ipmi_watchdog

Now,as you see, it have loaded,create the IPMI device:

mknod /dev/ipmi0 c `cat /proc/devices | grep ipmidev | awk '{print $1}' ` 0

you can then use ipmitool now !

#ipmitool lan print 1

                        :     O=OEM

and you can reconfigure ipmi sets:

# ipmitool -I open lan set 1 ipsrc static

# ipmitool -I open lan set 1 ipaddr 192.168.101.154
Setting LAN IP Address to 192.168.101.154

# ipmitool -I open lan set 1 defgw ipaddr 192.168.101.1
Setting LAN Default Gateway IP to 192.168.101.1

# ipmitool -I open lan set 1 netmask 255.255.255.0
Setting LAN Subnet Mask to 255.255.255.0

# ipmitool -I open lan set 1 access on

#ipmitool -I open user set password 2 askwan.com

logo to another server,check the server's system event log:

# ipmitool -I lan -H 192.168.101.154 -U root -a sel list

net-snmp
下载地址：http://ncu.dl.sourceforge.net/project/net-snmp/net-snmp/5.4.2.1/net-snmp-5.4.2.1.tar.gz
解压然后编译，编译参数

如编译报错：

这是缺少libperl-dev开发库,安装上

然后make ;make install
可以用snmpconf配置snmpd.conf，也可用例子文件

然后根据需要修改此文件

启动


测试

Webmin is a web-based interface for system administration for Unix. website
ok 开始 1.安装必要的deb包2. 下载 webmin deb包update: 2010-03-15 the newest version is 1.5.1.03.安装根据自己需要修改vi /etc/webmin/miniserv.conf文件
4.使修改生效

OS: debian 4.0 etch
此问题比较普遍 故记录之 且供参考
一般都是在apt-get update 后出错：

按照提示 运行apt-get  update这个指令 很遗憾 无论运行多少次 都无济于事

为演示这一过程 先下apt-key指令 import当前的keys
# apt-key update


当前系统有4个keys

增加上面列出的key
gpg --keyserver wwwkeys.eu.pgp.net --recv-keys  9AA38DCD55BE302B && apt-key add /root/.gnupg/pubring.gpg

再来看看系统中的trusted gpg keys信息
# apt-key list
/etc/apt/trusted.gpg
--------------------

OK 5个 最后一行正是刚才加入的
再次apt-get update 就应该没有问题了

#apt-get update

Reading package lists... Done

还有一种情况就是 key过期的问题 那么这时候可以一个个先删除系统中的key
比如
apt-key list
apt-key del 55BE302B
apt-key del BBE55AB3
...
然后删除debian-archive-keyring包
dpkg –purge debian-archive-keyring
再次重新安装
apt-get install debian-archive-keyring
基本上都能解决这个问题
