我在 Mac OS X 10.8.3 上尝试从围攻中运行以下命令时遇到了这个问题。
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
Transactions: 0 hits
Availability: 0.00 %

You can disable this annoying message by editing
the .siegerc file in your home directory; change
the directive 'show-logfile' to false.
最佳答案
问题可能是您用完了临时端口。要解决这个问题,要么增加要使用的端口数量,要么减少端口停留在 TIME_WAIT 中的持续时间,或者两者兼而有之。
扩展可用端口:
检查您当前的设置:
$ sudo sysctl net.inet.ip.portrange.hifirst
net.inet.ip.portrange.hifirst: 49152
将它调低以扩大您的窗口:
$ sudo sysctl -w net.inet.ip.portrange.hifirst=32768
net.inet.ip.portrange.hifirst: 49152 -> 32768
(hilast 应该已经是最大值,65536)
减少最大段生命周期
$ sudo sysctl -w net.inet.tcp.msl=1000
net.inet.tcp.msl: 15000 -> 1000
