Redhat与Ubuntu网卡设置方法比较

  RedHat linux中设置网卡固定ip
  之前在xwindow下的redhat-config-network 设置网卡固定ip发现不起作用,设置好后就是ping不通。就查了些资料,更改 /etc/sysconfig/network-scripts/ifcfg-eth0(第一个网卡为eth0),配置dns的文件为 /etc/resolv.conf,我保留了dhcp的配置,配置完后用ifconfig eth0 down;ifconfig eth0 up 就可以了。以下是配置文件的清单:

  #/etc/sysconfig/network-scripts/ifcfg-eth0:

  DEVICE=eth0

  BOOTPROTO=static

  BROADCAST=192.168.1.255

  IPADDR=192.168.1.10

  NETMASK=255.255.255.0

  NETWORK=192.168.1.0

  HWADDR=52:54:AB:2F:CF:F0

  GATEWAY=192.168.1.1

  ONBOOT=on

  TYPE=Ethernet

  #/etc/resolv.conf

  nameserver 202.109.14.5

  nameserver 202.96.209.5

  search localdomain

  或者使用命令:setup

  或者:

  route add -net 192.168.1.50 netmask 255.255.255.0 dev eth0

  或:

  ifconfig eth0 192.168.1.50 netmask 255.255.255.0

  Ubuntu 网卡设置,ip,mask,gateway,dns
  sudo vi /etc/network/interfaces

  //这个应该是决定是否启用这个端口

  auto eth0

  //静态设置IP

  iface eth0 inet static

  address 172.16.146.200

  netmask 255.255.255.0

  #broadcast 172.16.146.255

  gateway 172.16.146.254

  //通过dhcp动态设置

  iface eth0 inet dhcp

  //设置DNS服务器

  sudo vi /etc/resolv.conf

  nameserver 202.96.128.68

  nameserver 61.144.56.101

  nameserver 192.168.8.220

  //重新设置网络,以启用新设置

  sudo /etc/init.d/networking restart

  //ok
