1. ifconfig -a查看接口的名字
-bash-3.00# ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
pcn0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
inet 10.85.10.78 netmask ffffff00 broadcast 10.85.10.255
ether 0:c:29:36:9a:82
打开网络接口文件查看接口的名称
-bash-3.00# more /etc/hostname.pcn0
david
2. 修改host文件,使ip地址和接口一一对应
-bash-3.00# more /etc/hosts
::1 localhost
127.0.0.1 localhost
10.85.10.78 david loghost
3. 修改netmask
more/etc/netmsks
#more netmasks
10.85.10.0 255.255.255.0
4. 修改默认网关
-bash-3.00# more /etc/defaultrouter
10.85.10.165
5. 修改dns客户端
-bash-3.00# more resolv.conf
domain mysf
nameserver 218.104.78.2
6. 修改 /etc/nsswitch.conf 的12行
-bash-3.00# more /etc/nsswitch.conf
# You must also set up the /etc/resolv.conf file for DNS name
# server lookup. See resolv.conf(4).
hosts: files dns
从hosts:file改为hosts:files dns ,注意中间有空格.
7. 然后重启网络
-bash-3.00# ifconfig pcn0 down
-bash-3.00# ifconfig pcn0 up
