    --  如何解決Linux操作系統找不到網卡的問題
    1. 安裝網卡
    機器太新,以至于現有的Linux版本無法認出,比如機器找不到網卡,這時候怎么辦呢?


    別急,首先你需要知道網卡是什么型號的,以本實驗室新購入的電腦為例,它的網卡是集成的,型號是Realtek RTL8168/8111 PCI-E Gigabit Ethernet NIC。然后我們到Realtek的官方網站去下載相應的Linux驅動程序r8168-8.005.00.tar.bz2,按照說明安裝。


    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(看看有沒有加載網卡驅動)

    # /sbin/ifconfig –a(看看有沒有相關網卡被啟動的信息)


    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,...


    這里也可以通過系統→管理→網絡來設置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,在該文本中,增加兩行:


    127.0.0.1 localhost.localdomain localhost

    192.168.4.101 node3(根據機器本身情況設置)


    修改:vi /etc/hosts.equiv,增加一行:(如果沒有該文本,可建立一個)


    node3


    3. 啟動ssh服務


    大部分的Linux版本應該都會自帶該程序


    #ssh-keygen

    #cd .ssh

    #cp id_rsa.pub authorized_keys

    #ssh node3(如果成功,會顯示上次登陸的時間, node3是主機名)


    附加信息:

    ifup eth0看看能否啟動eth0

    lsmod看看有沒有加載網卡驅動

    dmesg看看有沒有網卡啟動時的錯誤信息
