在内里写入DNS处事器地点 设置主机名 设置/etc/sysconfig/network文件。

主要用途： 1、查察网络接口配置： ifconfig a或ifconfig 网络接口 a 2、网络设置 ifconfig 网络接口 [add/del] IP地点 netmask 子网掩码 例：ifocnfig eth0 10.2.3.4 [netmask 255.255.255.0] 3、网络接口的激活/封锁 名目：ifconfig 网络接口 up/down 设置dns 成立/etc/resolv.conf文件， 0% packet loss，同时利用hostname 修改主机名 利用例子： 复制代码 代码如下: [root@twin0898 sysconfig]# cat network network networking/ network-scripts/ [root@twin0898 sysconfig]# cat network NETWORKING=yes GATEWAY=125.39.149.1 HOSTNAME=twin0898 NETWORKING_IPV6=no 通用名目： 1、到网络的网关 route add/delete -net 方针网络 netmask 掩码 gw 网关地点 [dev 网络接口] 2、到单一主机的网关 route add/delete -host 方针主机 gw 网关地点 [dev 网络接口] 3、添加默认网关： route add default gw 网关地点 查抄主机路由表：route， time 11004ms rtt min/avg/max/mdev = 29.954/31.148/32.608/0.704 ms // netstat -nr 复制代码 代码如下: root@CinemaTest2:/usr/local/jdk# netstat -nr Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 0.0.0.0 192.168.232.2 0.0.0.0 UG 0 0 0 eth0 192.168.232.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 // nslookup vip.jb51.net 复制代码 代码如下: root@CinemaTest2:/etc# nslookup vip.jb51.net Server: 192.168.8.150 Address: 192.168.8.150#53 Non-authoritative answer: vip.jb51.net canonical name = movie.jb51.net. movie.jb51.net canonical name = movie.kankan.co.sandai.net. Name: movie.kankan.co.sandai.net Address: 114.80.189.60 Name: movie.kankan.co.sandai.net Address: 119.147.41.209 ， 12 received，netstat -nr // 总结如下： 1、网络设置查抄：ifconfig -a 2、连通性查抄：ping、traceroute 3、路由表查抄：route或netstat nr 4、DNS客户端运行状态查抄：nslookup // 利用例子如下 // ifconfig -a 复制代码 代码如下: root@CinemaTest2:/usr/local/jdk# ifconfig -a eth0 Link encap:Ethernet HWaddr b8:ac:6f:38:10:c6 inet addr:192.168.232.127 Bcast:192.168.232.255 Mask:255.255.255.0 inet6 addr: fe80::baac:6fff:fe38:10c6/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:42918159 errors:0 dropped:0 overruns:0 frame:0 TX packets:40893832 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:30644395811 (30.6 GB) TX bytes:30932951131 (30.9 GB) Interrupt:16 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:917 errors:0 dropped:0 overruns:0 frame:0 TX packets:917 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:81417 (81.4 KB) TX bytes:81417 (81.4 KB) // ping vip.jb51.net 复制代码 代码如下: PING movie.kankan.co.sandai.net (114.80.189.60) 56(84) bytes of data. 64 bytes from 114.80.189.60: icmp_seq=1 ttl=54 time=31.2 ms 64 bytes from 114.80.189.60: icmp_seq=2 ttl=54 time=29.9 ms 64 bytes from 114.80.189.60: icmp_seq=3 ttl=54 time=31.1 ms 64 bytes from 114.80.189.60: icmp_seq=4 ttl=54 time=30.5 ms 64 bytes from 114.80.189.60: icmp_seq=5 ttl=54 time=31.4 ms 64 bytes from 114.80.189.60: icmp_seq=6 ttl=54 time=32.6 ms 64 bytes from 114.80.189.60: icmp_seq=7 ttl=54 time=30.8 ms 64 bytes from 114.80.189.60: icmp_seq=8 ttl=54 time=30.9 ms 64 bytes from 114.80.189.60: icmp_seq=9 ttl=54 time=32.0 ms 64 bytes from 114.80.189.60: icmp_seq=10 ttl=54 time=31.3 ms 64 bytes from 114.80.189.60: icmp_seq=11 ttl=54 time=31.3 ms 64 bytes from 114.80.189.60: icmp_seq=12 ttl=54 time=30.3 ms --- movie.kankan.co.sandai.net ping statistics --- 12 packets transmitted，。
