centos5.4之netstat学习笔记

查看了netstat的man手册，感觉有些晕；原因何在呢，大学时，计算机网络学得一般子。现在看起来好多术语不太懂，勉强了解了下它的用法

为了便于学习，贴下相关的netstat的输出结果，作点小边注

[root@localhost ~]# netstat
Active Internet connections (w/o servers)

协议
本地未收到的字节数
send-Q是远程主机未收到的字节数
本地socket的地址及端口
远程socket的地址及端口
socket的状态 --这个状态有很多值，请查阅man手册，看得有些糊，太多了

getnameinfo failed
getnameinfo failed

Active UNIX domain sockets (w/o servers)

netstat的输出类型与第一个参数有关，比如：
netstat -r
netstat -a

小结：
netstat与网络有密切关系，要学习的东西太多
