Linux下,如何和 DHCP 要IP

當您發現裝置沒有要到IP時:

可以下這個指令:
# dhclient

Linux-CPU溫度監控

通常有二種方式可以知道CPU的溫度, 1. 透過 ACPI Reprot, 2. 透過 Super IO Report

方法1.

# cat / proc/ acpi/ thermal_zone/ THM/ temperature

temperature: 37 C

但有時 PC會沒有出現 THM 資料夾,這個問題沒再繼續解決下去,若沒有資訊則可以使用 Super IO方式來測量溫度

方法2

使用 Super IO方式測量,需使用 lm sensors這個軟體

安裝 lm-sensors:
# apt-get install lm-sensors

設定監控選項
# sensors-detect (如果不曉得全都按 YES)

重開機
# reboot

開完機後再輸入
#sensors

W83627DHG SuperIO 遇到問題:

insmod /lib/modules/2.6.31-6-generic/kernel/drivers/hwmon/w83627ehf.ko

FATAL: Error inserting w83627ehf (/lib/modules/2.6.31-6-generic/kernel/drivers/hwmon/w83627ehf.ko): Device or resource busy

dmesg :

[10910.136417] w83627ehf: Found W83627DHG chip at 0×290

[10910.136481] ACPI: I/O resource w83627ehf [0x295-0x296] conflicts with ACPI region HWRE [0x290-0x299]

[10910.136484] ACPI: Device needs an ACPI driver

主要是被 ACPI 占住 resource

解决方法是添加内核启动参数 acpi_enforce_resources=lax
