tdns-server-proxy

Tdns-server-proxy is a server-side proxy for DNS that takes connection (TCP/TLS) based DNS queries from client and forwards them to a recursive DNS server over UDP. Ideally, the recursive DNS server should be running at the same host as this proxy. It also forwards responses from the recursive DNS server back to client over TCP/TLS. It can be used to pair with tdns-client-proxy to accomplish T-DNS's features, such as query pipelining and out-of-order responses. It tracks the current "https://datatracker.ietf.org/doc/draft-ietf-dprive-dns-over-tls Specification for DNS over TLS, draft-ietf-dprive-dns-over-tls-09, enabling direct TLS on port 853 by default, with TCP and STARTTLS as options. A man page (README.man in the package) describes how to use this proxy.

Tdns-server-proxy 是一种DNS服务器端代理，它从客户端接收基于连接（TCP/TLS）的DNS查询，并通过UDP将它们转发给递归DNS服务器。理想情况下，递归DNS服务器应运行在与该代理相同的宿主机上。同时，它还将递归DNS服务器的响应通过TCP/TLS转发回客户端。该代理可配合 tdns-client-proxy 使用，以实现 T-DNS 的特性，如查询流水线和乱序响应。它跟踪当前“https://datatracker.ietf.org/doc/draft-ietf-dprive-dns-over-tls”规范（DNS over TLS，草案-ietf-dprive-dns-over-tls-09），默认情况下通过端口853启用直接TLS，并支持TCP和STARTTLS作为选项。该软件包中的man页面（README.man）详细描述了如何使用此代理。
