在哪里可以找到C ++ DNS库？ [英] Where can I find a C++ DNS Library?

问题描述

我知道DNS通常由操作系统处理，但是我的工作假定DNS已经在目标系统上被破坏（这是诊断DNS配置错误的工具）。因此，我需要自己实现DNS，以检查从系统返回的已知好的DNS服务器的结果。

您可以使用NSLookup或Dig工具来手动指定DNS服务器地址，但是出现Windows API调用（例如GetAddressByName ）不允许我指定要查询的服务器，并改用系统配置的目标。

我试图在DNS上查找RFC，但不幸的是，他们对我来说很清楚，他们使HTTP规范看起来像是最清晰和最准确的规范。

我也不想重新发明别人以前已经做过的事情。

解决方案

您可以尝试： http：// 25thc。 com /〜william / projects / dns.c.html 。另请参阅需要在C中构建简单的DNS解析器

实际上，Google搜索DNS解析器C显示了几种可能性。

I know DNS is typically handled by the operating system, but I'm working under the assumption that DNS has been broken on the target system (this is a tool to diagnose DNS misconfiguration). I therefore need to implement DNS myself, to check the results I get back from the system against a known good DNS server.

You can do this with the NSLookup or Dig tools, specifying a DNS server address manually, but it appears the Windows API calls for doing this (e.g. GetAddressByName) don't allow me to specify a server to query, and use the system's configured target instead.

I tried to look for the RFCs on DNS, but unfortunately they are clear as mud to me -- they make the HTTP spec look like the clearest and most well written spec ever produced.

I also don't want to reinvent something that someone else has already done several times before.

解决方案

You might try: http://25thandclement.com/~william/projects/dns.c.html . Also, see Need To Build Simple DNS Resolver in C

Actually, a Google search of "DNS resolver C" reveals several possibilities.
