#ifconfigeth0
ifconfig下令显现信息申明:
Linkencap收集接口范例,如以太网或PPP等
HWadrr网卡的Mac地点。每块网卡都有本人的编号,用于在以太网协定下定位收集主机
inetaddr此接口对应的IP地点
收集接口形态标记UP―收集接口被启用
RUNNING―接口正在运转
BROADCAST―撑持播送IP寻址体例
MULTICAST―撑持多播IP寻址体例
LOOPBACK―暗示当地回环装备接口
MTUMessagetransferunit,此接口所能传输的最年夜frame数
Metric此接口的Metric数,用于引诱路由决议
Bcast播送地点,一般是收集的最初一个IP地点
Mask子网掩码
RXpackets吸收的封包总数、毛病数、丢失数和溢流数
TXpackets发送的封包总数、毛病数、丢失数和溢流数
collisions抵触数(当多个NIC同时利用网线传输数据时会发生抵触)
txqueuelen指出收集接口能够存储的数据包的个数
RXbytes与RXpackets相似,暗示吸收的详细字节数
TXbytes与TXpackets相似,暗示发送的详细字节数
Interrupt网卡利用的中止(IRQ)
Baseaddress网卡利用的内存地点
2、设置PPPOE客户端软件Centos默许装置了PPPOE软件,间接设置[root@sample~]#adsl-setup ←创建ADSL毗连

输出server,这暗示利用ADSL拨号主动取得的DNS办事器IP地点大概202.106.0.20备用DNS202.106.148.1PASSWORD

#adsl-setup这个工具举行设置:3.启动PPPOE客户端软件#adsl-start←启动ADSL毗连
#←稍等半晌后若启动乐成后呈现提醒符(无任何提醒即意味着毗连乐成)假如不乐成,请反省网线、ADSLMODEM等物理装备,并检察/var/log/messages中的信息#adsl-stop封闭和ISP的毗连#adsl-status检察以后毗连的形态4.测试#ifconfig-a
在输入中应当含有关于ppp0的一堆信息,个中还绑定了IP地点,申明已从拨号中取得了IP地点。#netstat-nr
检察路由表信息,这时候的默许路由应当是下面取得的IP地点。假如没有默许路由,我们能够手动增添:#routeadddefaultgw下面取得的IP地点
#nslookupwww.ckuyun.com.cn
假如剖析出新浪的IP,申明已从拨号中准确取得了DNS办事器
最初,利用下令ping某个域名或IP,假如有呼应,暗示你已半途而废了。
