Question

我在尝试从Mac OS X 10.8.3上的围攻中运行以下cmd时遇到了这个问题。

siege -d1 -c 20 -t2m -i -f -r10 urls.txt

Siege的输出如下：

** SIEGE 2.74
** Preparing 20 concurrent users for battle.
The server is now under siege...
done.
siege aborted due to excessive socket failure; you
can change the failure threshold in $HOME/.siegerc

You can disable this annoying message by editing
the .siegerc file in your home directory; change
the directive 'show-logfile' to false.

问题可能是你用完了短暂的端口。要解决此问题，请扩展要使用的端口数，或者减少端口保持TIME_WAIT或两者的持续时间。

展开可用端口：

检查您当前的设置：

$ sudo sysctl net.inet.ip.portrange.hifirst

net.inet.ip.portrange.hifirst: 49152

将其设置为较低以展开窗口：

$ sudo sysctl -w net.inet.ip.portrange.hifirst=32768

net.inet.ip.portrange.hifirst: 49152 -> 32768

（希拉斯特应该已经达到最大值，65536）

缩短段的最长生命周期

$ sudo sysctl -w net.inet.tcp.msl=1000

net.inet.tcp.msl: 15000 -> 1000

由于套接字故障导致Siege中止
