家里的电脑,就一台,adsl上网,设置了IP地址192.168.0.1,经常一开机还没拨号就告诉我IP地址冲突,本地界面被禁用。尝试改成同一网段的其他地址,发现能PING通192.168.0.1(有时是192.168.0.2或两个地址都被占用)。难道adsl没拨通就能和别的机器通讯了?adsl为轿接模式。adsl拨号上网正常,重装系统无效(除了电信给的拨号程序什么也没装),网卡就一块。没病毒什么的,怎么回事?

Introduction to device drivers and device nodes This section provides an overview of the way in which peripheral components use the Unix Input/Output (I/O) subsystem. Physical devices, such as disk drives and modems, have a varied command interface and command interpretation. For this reason the Unix operating system defines a standard method of I/O that is used on any type of device that is at...
