由于过多的套接字故障，攻城术中止了 [英] Siege aborted due to excessive socket failure

问题描述

我在尝试从Mac OS X 10.8.3上的包围中逃脱以下cmd时遇到了此问题.

I have encountered this problem whilst trying to run off the following cmd from siege on Mac OS X 10.8.3.

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

Siege的输出如下:

The output from Siege is the following:

** 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

推荐答案

问题可能是您用完了临时端口.要解决此问题，请增加要使用的端口数量，或者减少端口在TIME_WAIT中停留的时间，或者两者兼而有之.

The problem may be that you run out of ephemeral ports. To remedy that, either expand the number of ports to use, or reduce the duration that ports stay in TIME_WAIT, or both.

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

降低它以扩大窗口:

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

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

(hilast应该已经达到最大值65536)

(hilast should already be at the max, 65536)

减少段的最大寿命

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

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