求解netstat -s命令
在netstat -s命令输出的列表中，某些域的统计信息对应的时间段是？
比如：
TCP Statistics for IPv4
Active Opens = 5217
Passive Opens = 80
Failed Connection Attempts = 2944
Reset Connections = 529
Current Connections = 9
Segments Received = 350143
Segments Sent = 347561
Segments Retransmitted = 6108
其中，Failed Connection Attempts = 2944 指的是什么时候到当前的失败连接总数吗？
[解决办法]
应该是系统开始运行
[解决办法]
连接失败尝试数
