网络链接调节器似乎对Lion，Mountain Lion上的网络行为没有影响 [英] Network Link Conditioner seems to have no effect on network behavior on Lion, Mountain Lion

问题描述

网络链接调节器首选项窗格（安装于用于Xcode的硬件IO工具 - 2012年7月下旬Apple开发人员网站上的DMG在打开时似乎没有任何效果。这个问题的原作者报告了Mountain Lion的症状。后来的编辑器在Lion上安装了Xcode 4.5.1时遇到了相同的症状和缺乏预期的网络行为更改。

启用后，/ var / log / system.log显示：

  1月17日17:36:14 matt-mmf-macbook [0x0-0x1d01d] .com.apple.systempreferences [ 371]：系统首选项（371,0x10fac7000）malloc：*** auto malloc [371]：错误：未注册线程上的GC操作。线程已隐式注册。中断auto_zone_thread_registration_error（）以进行调试。

 1月17日17:36:18 matt-mmf-macbook系统偏好设置[371]：启动网络链接护发素
  

并且网络连接不会显示所选配置文件指定的行为。

<有没有人成功地让它工作，或者弄清楚system.log中的错误可能意味着什么？截至2013-01-17，接受/更正的答案对于遇到症状的每个人都不起作用。

解决方案

i刚遇到同样的问题。在Lion上安装了Conditioner窗格，在更新到Mountain Lion后，它仍然可以在设置窗格中使用，但在打开时无效。

我修复了它删除Conditioner（右键单击设置窗格 - >删除Network ...）并从Hardware IO Tools Image（2012年7月下旬）重新安装。

希望它也适合你。我认为os x更新必须覆盖一些东西。

The Network Link Conditioner preference pane (installed from the "Hardware IO Tools for Xcode - Late July 2012" DMG on the Apple developer site) doesn't appear to have any effect when turned on. The original author of this question reported the symptoms on Mountain Lion. A later editor experienced the same symptoms and lack of expected network behavior change on Lion, with Xcode 4.5.1 installed.

When enabled, /var/log/system.log shows:

Jan 17 17:36:14 matt-mmf-macbook [0x0-0x1d01d].com.apple.systempreferences[371]: System Preferences(371,0x10fac7000) malloc: *** auto malloc[371]: error: GC operation on unregistered thread. Thread registered implicitly. Break on auto_zone_thread_registration_error() to debug.
Jan 17 17:36:18 matt-mmf-macbook System Preferences[371]: process command (simulate) failed
Jan 17 17:36:18 matt-mmf-macbook [0x0-0x1d01d].com.apple.systempreferences[371]: _nlc_start_simulation: (os/kern) failure
Jan 17 17:36:18 matt-mmf-macbook System Preferences[371]: Starting Network Link Conditioner

And the network connections do not exhibit the behavior specified by the selected profile.

Has anyone successfully gotten it to work, or figured out what the error in system.log might mean? As of 2013-01-17, the "accepted/correct" answer does not work for everyone experiencing the symptoms.

解决方案

i just had the same problem. Installed the Conditioner pane on Lion and after updating to Mountain Lion, it still was available in the settings pane, but had no effect when turned on.

i fixed that by just removing the Conditioner (right click in the settings pane -> Remove "Network...") and reinstalling it from the Hardware IO Tools Image (Late July 2012).

Hope it works too for you. i think the os x update must have overwritten something.
