            1. 安装网卡

            机械太新  ,以至于现有的Linux版本无法认出  ,好比机械找不到网卡  ,这时间怎么办呢  ?

            别急  ,首先你需要知道网卡是什么型号的 ,以本实验室新购入的电脑为例 ,它的网卡是集成的 ,型号是Realtek RTL8168/8111 PCI-E Gigabit Ethernet NIC  。然后我们到Realtek的官方网站去下载响应的Linux驱动法式r8168-8.005.00.tar.bz2  ,根据说明安装  。

            Unpack the tarball :

            # tar vjxf r8168-8.aaa.bb.tar.bz2

            Change to the directory:

            # cd r8168-8.aaa.bb

            If you are running the target kernel, then you should be able to do :

            # make clean modules (as root or with sudo)

            # make install

            # /sbin/depmod -a

            # /sbin/insmod ./src/r8168.ko (or r8168.o in linux kernel 2.4.x)

            You can check whether the driver is loaded by using following commands.

            # /sbin/lsmod | grep r8168(看看有没有加载网卡驱动)

            # /sbin/ifconfig ?Ca(看看有没有相关网卡被启动的信息)

            If there is a device name, ethX, shown on the monitor, the linux

            driver is loaded. Then, you can use the following command to activate

            the ethX.

            # ifconfig ethX up

            ,where X=0,1,2,...

            这里也可以通过系统→治理→网络来设置IP地址等 ,最后激活  。

            1. Set manually

            a. Set the IP address of your machine.

            # ifconfig ethX "the IP address of your machine"

            b. Set the IP address of DNS.

            Insert the following configuration in /etc/resolv.conf.

            nameserver "the IP address of DNS"

            c. Set the IP address of gateway.

            # route add default gw "the IP address of gateway"

            2. Set by doing configurations in /etc/sysconfig/network-scripts

            /ifcfg-ethX for Redhat and Fedora, or /etc/sysconfig/network

            /ifcfg-ethX for SuSE. There are two examples to set network

            configurations.

            a. Fix IP address:

            DEVICE=eth0

            BOOTPROTO=static

            ONBOOT=yes

            TYPE=ethernet

            NETMASK=255.255.255.0

            IPADDR=192.168.1.1

            GATEWAY=192.168.1.254

            BROADCAST=192.168.1.255

            2. 修改:#vi /etc/hosts  ,在该文本中  ,增添两行:

            127.0.0.1 localhost.localdomain localhost

            192.168.4.101 node3(凭据机械自己情形设置)

            修改:vi /etc/hosts.equiv  ,增添一行:(若是没有该文本  ,可建设一个)

            node3

            3. 启动ssh服务

            大部门的Linux版本应该都市自带该法式

            #ssh-keygen

            #cd .ssh

            #cp id_rsa.pub authorized_keys

            #ssh node3(若是乐成  ,会显示上次上岸的时间  , node3是主机名)

            附加信息:

            ifup eth0看看能否启动eth0

            lsmod看看有没有加载网卡驱动

            dmesg看看有没有网卡启动时的错误信息
