lm_sensors インストール （2004年8月28日）
サーバ機の温度、電圧、ファン回転速度などの情報をGETしてみる！！
その情報を得るには、lm_sensors と言うソフトが必要だそうで^_^;
インストールしてみることに・・・
OS環境は、Fedora Core1（カーネル 2.4.22-1.2199.nptl）です。
まずは、yumで、lm_sensorsをインストールします。
# yum install lm_sensors

I will do the following:
[install: lm_sensors 2.8.1-1.i386]
Is this ok [y/N]: ← ここで、Enterキー

環境を読み込んで、下記の様な設定の質問攻めに合います（￣ー￣）ニヤリッ
Yesと入力して答えてみました・・・
Enterキーでも、可能ですのね(^^ゞ
# sensors-detect
This program will help you determine which I2C/SMBus modules you need to
load to use lm_sensors most effectively. You need to have i2c and
lm_sensors installed before running this program.
Also, you need to be `root', or at least have access to the /dev/i2c-*
files, for most things.
If you have patched your kernel and have some drivers built-in, you can
safely answer NO if asked to load some modules. In this case, things may
seem a bit confusing, but they will still work.
BIOS vendor (ACPI): AOPEN
We can start with probing for (PCI) I2C or SMBus adapters.
You do not need any special privileges for this.
Do you want to probe now? (YES/no): YES
Probing for PCI bus adapters...
Use driver `i2c-i810' for device 00:02.0: Intel 82815 GMCH
Use driver `i2c-i801' for device 00:1f.3: Intel 82801BA ICH2
Probe succesfully concluded.
We will now try to load each adapter module in turn.
Load `i2c-i810' (say NO if built into your kernel)? (YES/no): YES
Module loaded succesfully.
Load `i2c-i801' (say NO if built into your kernel)? (YES/no):
Module loaded succesfully.
Do you now want to be prompted for non-detectable adapters? (yes/NO):
To continue, we need module `i2c-dev' to be loaded.
If it is built-in into your kernel, you can safely skip this.
i2c-dev is not loaded. Do you want to load it now? (YES/no): YES
Module loaded succesfully.
We are now going to do the adapter probings. Some adapters may hang halfway
through; we can't really help that. Also, some chips will be double detected;
we choose the one with the highest confidence value in that case.
If you found that the adapter hung after probing a certain address, you can
specify that address to remain unprobed. That often
includes address 0x69 (clock chip).
Next adapter: I810/I815 I2C Adapter (Bit-shift algorithm)
Do you want to scan it? (YES/no/selectively):
Next adapter: I810/I815 I2C Adapter (Bit-shift algorithm)
Do you want to scan it? (YES/no/selectively):
Next adapter: I810/I815 DDC Adapter (Bit-shift algorithm)
Do you want to scan it? (YES/no/selectively):
Next adapter: SMBus I801 adapter at 5000 (Non-I2C SMBus adapter)
Do you want to scan it? (YES/no/selectively):
Can't open /dev/i2c-2
Some chips are also accessible through the ISA bus. ISA probes are
typically a bit more dangerous, as we have to write to I/O ports to do
this. Do you want to scan the ISA bus? (YES/no):
Probing for `National Semiconductor LM78'
Trying address 0x0290... Failed!
Probing for `National Semiconductor LM78-J'
Trying address 0x0290... Failed!

Some Super I/O chips may also contain sensors. Super I/O probes are
typically a bit more dangerous, as we have to write to I/O ports to do
this. Do you want to scan for Super I/O sensors? (YES/no):

Now follows a summary of the probes I have just done.
Just press ENTER to continue:
Driver `w83781d' (should be inserted):
Detects correctly:
* ISA bus address 0x0290 (Busdriver `i2c-isa')
Chip `Winbond W83627HF' (confidence: 8)
Driver `w83627hf' (may not be inserted):
Misdetects:
* ISA bus address 0x0290 (Busdriver `i2c-isa')
Chip `Winbond W83627HF Super IO Sensors' (confidence: 8)
↑センサーはこれが検出されたって事？！
I will now generate the commands needed to load the I2C modules.
Sometimes, a chip is available both through the ISA bus and an I2C bus.
ISA bus access is faster, but you need to load an additional driver module
for it. If you have the choice, do you want to use the ISA bus or the
I2C/SMBus (ISA/smbus)?
To make the sensors modules behave correctly, add these lines to
/etc/modules.conf:
#----cut here----
# I2C module options
alias char-major-89 i2c-dev
#----cut here----
To load everything that is needed, add this to some /etc/rc* file:
#----cut here----
# I2C adapter drivers
modprobe i2c-isa
# I2C chip drivers
modprobe w83781d
# sleep 2 # optional
/usr/local/bin/sensors -s # recommended
#----cut here----
WARNING! If you have some things built into your kernel, the list above
will contain too many modules. Skip the appropriate ones! You really should
try these commands right now to make sure everything is working properly.
Monitoring programs won't work until it's done.
Do you want to generate /etc/sysconfig/lm_sensors? (YES/no):
Copy prog/init/lm_sensors.init to /etc/rc.d/init.d/lm_sensors
for initialization at boot time./etc/rc.d/rc.local ファイルに
#----cut here----
# I2C module options
alias char-major-89 i2c-dev
#----cut here---- 上記をコピー＆貼り付けしました。
/etc/conf.modules ファイルに
#----cut here----
# I2C adapter drivers
modprobe i2c-isa
# I2C chip drivers
modprobe w83781d
# sleep 2 # optional
/usr/local/bin/sensors -s # recommended
#----cut here----上記をコピー＆貼り付けしまし（￣ー￣）
そんでもって・・・ マシンを再起動！！
