Event ID: 30013 The DHCP allocator has disabled itself

博客围绕Microsoft事件30013展开,指出这是NAT DHCP分配器与接口冲突,即系统APIPA和NAT的DHCP冲突,重新配置NAT可解决该错误。同时提到使用VMware软件时,重新配置接口最好有虚拟机运行,对于NAT不能分配IP地址,重启RRAS服务即可。

TypeError 
DescriptionThe DHCP allocator has disabled itself on IP address 169.254.236.250, since the IP address is outside the 192.168.0.0/255.255.255.0 scope from which addresses are being allocated to DHCP clients. To enable the DHCP allocator on this IP address, please change the scope to include the IP address, or change the IP address to fall within the scope.

From a newsgroup post: "I was having problems running ICS (Internet Connection Sharing) on my Win2K Pro. Whenever a Win98 client on the network tried to browse the web, I got an error event 31003. I resolved this problem by removing the ZoneAlarm software from my Win2k machine".

From a newsgroup post: "Make sure no DHCP service is running on your machines. ICS contains its own addressing solution and it sounds like this is conflicting with the DHCP client service".

From a newsgroup post: "I had this problem with Windows XP. Microsoft online support suggested checking all network connections in "My Network Places" and disabling any sharing of internet connections. I found one item which had this and I unchecked the internet sharing box. The error has not yet recurred".

169.254.x.x is the ip subnet that Windodws 2000 DHCP Client assigns to a machine when it cannot contact a DHCP server. The 192.168.0.0 is the range used by the Internet Connection Sharing service. So this event appears to be a conflict between these two components.

Microsoft event 30013 from source ipnathlp

Details
Product:Windows Operating System
ID:30013
Source:ipnathlp
Version:5.2
Symbolic Name:IP_AUTO_DHCP_LOG_NON_SCOPE_ADDRESS
Message:The DHCP allocator has disabled itself on IP address %1, since the IP address is outside the %2/%3 scope from which addresses are being allocated to DHCP clients. To enable the DHCP allocator on this IP address, please change the scope to include the IP address, or change the IP address to fall within the scope.
   
Explanation

The IP address is not within the scope of addresses allocated for Internet Connection Sharing (ICS) or Routing and Remote Access network address translation (NAT).

The most probable cause is incorrect manual configuration of the IP address.

   
User Action

To automatically reconfigure the IP address, disable and then re-enable either ICS or the Routing and Remote Access NAT component.

To disable and re-enable ICS

  1. In Windows Explorer, click My Network Places.
  2. Right-click the ICS adapter that you want to share, and then select Properties.
  3. Click the Advanced tab.
  4. In the Internet Connection sharing area, clear the Allow other network users to connect through this computer's internet connection box, and then click OK.
  5. In the Network Connections window, right-click the ICS adapter, and then select Properties.
  6. Click the Advanced tab.
  7. Select the Allow other network users to connect through this computer's internet connection box, and then click OK.

You can disable and then re-enable the Routing and Remote Access NAT component by opening Routing and Remote Access in Administrative Tools.

基本上,看了上面的评论, 再看了Microsoft event 30013 from source ipnathlp,知道这是我的NAT DHCP分配器与接口冲突, 系统APIPA和NAT的DHCP冲突. 重新配置了NAT就行了,不再出现此错误信息.
因为我用的时VMware软件, 当没有上虚拟机时, 那个接口也一直在运行,即不是叉叉的. 所以重新配置接口时,最好有一台虚拟机在运行着.

2005.3.7,lem:对于NAT不能向接口分配IP地址,则重新启动RRAS服务即可.

`boost::container::allocator` 是 Boost 容器库中的一个重要组件,主要用于提供灵活的内存分配策略。以下是对其用法和常见问题解决方案的详细介绍。 ### 什么是 `boost::container::allocator` `boost::container::allocator` 是一个模板类,设计用来替代标准 C++ 的 `std::allocator`。它提供了更多的灵活性和性能优化选项,特别是在处理复杂容器或特定场景下(如嵌入式系统或多线程环境)时表现尤为突出[^1]。 #### 关键特性 - **兼容性**: 完全兼容 STL 接口,可以直接替换 `std::allocator`。 - **扩展功能**: 提供额外的功能支持,例如自定义池分配器(pool allocator),这有助于减少碎片并提高效率。 - **线程安全性**: 对于某些实现方式,默认情况下可能是线程安全的;但是具体取决于底层机制及配置设置[^2]。 --- ### 基本使用方法 下面展示如何利用 `boost::container::vector` 结合自定义分配器创建一个简单向量: ```cpp #include <boost/container/vector.hpp> #include <iostream> struct MyAllocator : boost::container::new_allocator<int> {}; int main(){ typedef boost::container::vector<int, MyAllocator> IntVector; IntVector v(MyAllocator()); for(auto i = 0; i != 10; ++i){ v.push_back(i); } for(auto elem : v){ std::cout << elem << ' '; } } ``` 在这个例子中,我们继承了 `boost::container::new_allocator<T>` 来构建自己的分配器类型 `MyAllocator` ,然后将其作为第二个模板参数传递给 `boost::container::vector` 。这样做的好处是可以轻松定制行为而不影响原有接口的一致性和易用性[^3]。 --- ### 解决常见问题 #### Q: 如何解决多线程环境下共享同一实例引发的竞争条件? A: 当多个线程同时访问同一个由 `boost::container::allocator` 管理的对象时可能会出现问题。可以通过如下几种途径缓解此风险: - 使用线程局部存储(TLS)确保每条独立执行路径都有各自专属副本; - 将整个结构保护起来采用互斥锁(mutexes)同步操作序列; - 利用无状态(stateless)分配器避免潜在副作用传播[^4]。 #### Q: 自定义分配器能否提升程序整体运行速度? A: 这主要看具体情况而定。理论上讲精心挑选适合应用场景特点的分配方案确实能够带来显著收益——尤其是当频繁请求小块连续空间时。然而盲目追求极致也可能引入不必要的开销甚至适得其反。因此务必经过充分测试验证后再做决定[^5]. ---
