标题: 11种网络状态 IDLE CONNECTED
在UNIX网络编程第一卷中列出了11中状态
但是我在fedora和solaris下用netstat看有CONNECTED（fodera）和IDLE（solaris）两种不是11种里面的，这些是新的还是是其他状态的别名呢

CONNECTED就相当于windows中的ESTABLISHED吧

solaris的中有这13种输出

switch (state) {
case TCPS_CLOSED:
cp = "CLOSED";
break;
case TCPS_IDLE:
cp = "IDLE";
break;
case TCPS_BOUND:
cp = "BOUND";
break;
case TCPS_LISTEN:
cp = "LISTEN";
break;
case TCPS_SYN_SENT:
cp = "SYN_SENT";
break;
case TCPS_SYN_RCVD:
cp = "SYN_RCVD";
break;
case TCPS_ESTABLISHED:
cp = "ESTABLISHED";
break;
case TCPS_CLOSE_WAIT:
cp = "CLOSE_WAIT";
break;
case TCPS_FIN_WAIT_1:
cp = "FIN_WAIT_1";
break;
case TCPS_CLOSING:
cp = "CLOSING";
break;
case TCPS_LAST_ACK:
cp = "LAST_ACK";
break;
case TCPS_FIN_WAIT_2:
cp = "FIN_WAIT_2";
break;
case TCPS_TIME_WAIT:
cp = "TIME_WAIT";
break;
多了TCPS_IDLE TCPS_IDLE两个
定义分别是
#define TCPS_IDLE -5 /* idle (opened, but not bound) */
#define TCPS_BOUND -4 /* bound, ready to connect or accept */

---------------------------------------------------------------------------------------------------------------------
fedora在linux的2.4.0中没有找到相关的代码
在tcp.h中找到了
enum {
  TCP_ESTABLISHED = 1,
  TCP_SYN_SENT,
  TCP_SYN_RECV,
  TCP_FIN_WAIT1,
  TCP_FIN_WAIT2,
  TCP_TIME_WAIT,
  TCP_CLOSE,
  TCP_CLOSE_WAIT,
  TCP_LAST_ACK,
  TCP_LISTEN,
  TCP_CLOSING,    /* now a valid state */

  TCP_MAX_STATES /* Leave at the end! */
};
没有CONNTECTED
有了解的吗
