netstat的输出结果分为两个部分：
Active Internet connections，有源TCP连接，"Recv-Q"和"Send-Q"指%0A的是接收队列和发送队列。这些数字一般都是0。如果不是则表示软件包正在队列中堆积。Active UNIX domain sockets，有源Unix域套接口(和网络套接字一样，但是只能用于本机通信，性能可以提高一倍)。
Proto 显示连接使用的协议
RefCnt 连接到本套接口上的进程号
Types 套接口的类型
State 套接口当前的状态
Path 连接到套接口的其它进程使用的路径名
常见参数
-a (all) 显示所有选项，默认不显示LISTEN相关
-t (tcp) 仅显示tcp相关选项
-u (udp 仅显示udp相关选项
-n 拒绝显示别名，能显示数字的全部转化成数字
-l 仅列出有在 Listen (监听) 的服务状态
-p 显示建立相关链接的程序名
-r 显示路由信息，路由表
-e 显示扩展信息，例如uid等
-s 按各个协议进行统计
-c 每隔一个固定时间，执行该netstat命令
提示：LISTEN和LISTENING的状态只有用-a或者-l才能看到
1. 列出所有端口 (包括监听和未监听的)

8. 显示核心路由信息 netstat -r
[root@TA30-53 creditcc2.0]# netstat -rKernel IP routing tableDestination Gateway Genmask Flags MSS Window irtt Iface10.143.128.0 * 255.255.255.0 U 0 0 0 eth2link-local * 255.255.0.0 U 0 0 0 eth2default 10.143.128.1 0.0.0.0 UG 0 0 0 eth2
注意： 使用 netstat -rn 显示数字格式，不查询主机名称。
9. 找出程序运行的端口
并不是所有的进程都能找到，没有权限的会不显示，使用 root 权限查看所有的信息
[root@TA30-53 creditcc2.0]# netstat -ap|grep sshtcp 0 0 *:EtherNet/IP-1 *:* LISTEN 28485/sshd tcp 0 0 TA30-53.local:EtherNet/IP-1 10.108.22.231:61289 ESTABLISHED 25162/sshd
找出端口32893进程pid
[pso@localhost conf]$ netstat -anp|grep ':32893'
(Not all processes could be identified, non-owned process info will not be shown, you would have to be root to see it all.)tcp 0 0 ::ffff:10.151.15.103:32893 :::* LISTEN 97927/java
找出运行在指定端口的进程
[root@TA30-53 creditcc2.0]# netstat -an|grep ':6060'tcp 0 0 0.0.0.0:6060 0.0.0.0:* LISTEN
10. 显示网络接口列表
[root@TA30-53 creditcc2.0]# netstat -iKernel Interface tableIface MTU Met RX-OK RX-ERR RX-DRP RX-OVR TX-OK TX-ERR TX-DRP TX-OVR Flgeth2 1500 0 5422062 0 0 0 4435994 0 0 0 BMRUlo 65536 0 190 0 0 0 190 0 0 0 LRU
显示详细信息，像是 ifconfig 使用 netstat -ie
[root@TA30-53 creditcc2.0]# netstat -ieKernel Interface tableeth2 Link encap:Ethernet HWaddr 00:50:56:A3:02:9B inet addr:10.143.128.165 Bcast:10.143.128.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:5422475 errors:0 dropped:0 overruns:0 frame:0 TX packets:4436404 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:2715859558 (2.5 GiB) TX bytes:654976728 (624.6 MiB)lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:190 errors:0 dropped:0 overruns:0 frame:0 TX packets:190 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:10411 (10.1 KiB) TX bytes:10411 (10.1 KiB)
11. IP和TCP分析
查看连接某服务端口最多的的IP地址
netstat -nat | grep "10.143.128.165:6060" |awk '{print $5}'|awk -F: '{print $1}'|sort|uniq -c|sort -nr|head -20
TCP各种状态列表
