; 1. 安装网卡 机器太新，以至于现有的Linux版本无法认出，比如机器找不到网卡，这时候怎么办呢？ 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的官方网站去下载相应的Linux驱动程序r8168-8.005.00.tar.bz2，按照说明安装。 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 –a(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→管理→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，增加两行： 127.0.0.1 localhost.localdomain localhost 192.168.4.101 node3（根据机器本身情况设置） 修改：vi /etc/hosts.equiv，增加一行：(如果没有该文本，可建立一个) node3 3. 启动ssh服务 大部分的Linux版本应该都会自带该程序 ＃ssh-keygen ＃cd .ssh ＃cp id_rsa.pub authorized_keys ＃ssh node3（如果成功，会显示上次登陆的时间， 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
