vmware 下找不到ifcfg-eth0的问题 http://www.linuxdiyf.com/viewarticle.php?id=90924 在windowXP下安装了suse linux，在vmware下选择了host-only方式与主机通信。 使用host-only方式与主机通信，vmware使用的是VMware Network Adapter VMnet1虚拟网卡，查看该网卡的IP是 192.168.174.1。 在虚拟机下面的linux下遇到了一下几个问题： 1、找不大 eth0网卡，也就连不上网络。症状是ifconfig以后只现实lo，不显示eth0。 解决方法： ifconfig eth0 up。这样ifconfig以后就显示了eth0。 找到eth0以后，再运行ifconfig eth0 192.168.174.2 netmask 255.255.255.0。即可与主机通信。 2、经过上面步骤是找到了eth0，可是重启以后又没有了。 解决方法： cd /etc/sysconfig/network/ cp ifcfg-lo ifcfg-eth0 vim ifcfg-eth0 修改配置如下 IPADDR=192.168.174.2 NETMASK=255.255.255.0 NETWORK=192.168.174.0 BROADCAST=192.168.174

I have a script that runs from udev when I plug in my external drive. It always worked. But after upgrading from Linux 3.8/Xorg 1.12/Mint 14 ( Ubuntu 12.10 compatible) to Linux 3.11/Xorg 1.14/Mint 16 ( Ubuntu 13.10 compatible), it doesn't work anymore. The script still runs, but none of the commands that require the display work. I figured that out by quitting the udev daemon and manually run udevd --debug for verbose output (more below). This script used to work in Mint 14/12.10 : export DISPLAY=:0 UUID=$1 DEV=$2 notify-send -t 700 "mounting $DEV ($UUID)" gnome-terminal -t "Backing up home...

一、为什么需要这个 服务器通常有多块网卡，有板载集成的，同时也有插在PCIe插槽的。 Linux系统的命名原来是eth0,eth1这样的形式，但是这个编号往往不一定准确对应网卡接口的物理顺序。 为解决这类问题,dell开发了biosdevname方案(systemd v197版本中将dell的方案作了进一步的一般化拓展)。 目前的Centos既支持dell的biosdevname，也支持systemd的方案。 二、Centos7中的命名规则 传统命名：以太网eth[0,1,2,...] 2.1、可预测功能 　　　　udev支持多种不同的命名方案： 　　　　　　基于Firmware , 拓扑结构　　 　udev支持多种不同的命名方案：UDEV是系统在用户空间探测内核空间，通过sys接口所输出的硬件设备，并配置的硬件设备的一种应用程序，在centos7上UDEV支持多种不同的命名方案，无非就是支持基于固件的命名（firmware,基于主板上rom芯片）或者是通过总线拓扑（PCI总线）结构来命名。总线拓扑（PCI总线）结构命名主要是根据对应设备所在的位置来命名，slot设备上的第几个接口方式命名，这样命名的方式就是能够实现自动命名，只要接口不坏，无论是哪一块网卡插上去其名称一定是固定的。 　 　 （1）网卡命名机制 　　　　systemd对网络设备的命名方式： 　　　　　　（a

It's apparently possible to get a lot of info relating to attached disks using the udisks binary: udisks --show-info /dev/sda1 udisks is apparently just enumerating the data which is available udev. Is it possible to get this information using python? say for example if i just wanted to retrieve the device serial, mount point and size. mark You can use Udisks via dbus directly in python. import dbus bus = dbus.SystemBus() ud_manager_obj = bus.get_object("org.freedesktop.UDisks", "/org/freedesktop/UDisks") ud_manager = dbus.Interface(ud_manager_obj, 'org.freedesktop.UDisks') for dev in ud

Is there a Bash script and/or daemon that I can write that will detect a specific USB drive and then sync that drive with a directory? For future reference, here's how to run a bash script upon detection of a USB drive. Connect your device and run lsusb to retrieve the device's info. You should see something similar to this: $ lsusb Bus 002 Device 039: ID 0bc2:2100 Seagate RSS LLC In this case, the vendor ID of the device is 0bc2 and the product ID is 2100. Now you can create your UDEV rule using a text editor of your choice. $sudo vi /etc/udev/rules.d/85-my_usb_device_rule.rules And add this:

I knew that udev plays on the linux system and it receives uevents sent from the kernel through netlink socket. However, my questions are: How kernel sends out the event ? It must be something triggered by adding/removing device and then sends out events to udev. How does kernel do this? (Is there any code example I can find? ) udev receives these uevents only through netlink socket. This is the only way that udev does it. Is this correct? When uevent is sent out from the kernel, I knew it can do broadcast. However, Can it do unicast? Thanks for any feedback. Alexander Dzyoba It sends netlink

I am trying to get a list of currently plugged in USB devices in Ubuntu 10.10 and monitor changes that happen, like devices being plugged in or out using UDev and D-BUS. I'm fairly new to programming using D-BUS. I saw one example: Linux : How to detect is usb keyboard is plugged and unplugged only that one uses HAL and I know that HAL is deprecated. I found some working code, modified it a bit, only it doesn't work for any device only storage devices such as usb sticks, media players or cd-rom devices. I want the whole thing mice, keyboards, usb cameras chargers anything that is plugged in to
