## 项目历史与用法

Cntlm is a small C NTLM/NTLM Session Response/NTLMv2 authenticating HTTP proxy with TCP/IP tunneling, built to let applications that lack NTLM support work behind corporate Microsoft-style proxy infrastructure.

### 项目历史

The official SourceForge site presents Cntlm as a cross-platform proxy written in plain C with no external dependencies, connection caching, tunneling, SOCKS5 mode, and support for parent proxy failover. The project's public news shows active 0.35-era work in 2007, a larger 0.91 rewrite/testing cycle in 2010, and 0.92.x Windows and packaging fixes in 2011-2012.

### 采用历史

Cntlm was adopted by Unix users working behind NTLM-authenticated corporate proxies, especially when command-line package managers, browsers, version-control clients, or build tools could use a normal local HTTP proxy but could not authenticate to NTLM directly. This batch input records packages in Alpine, Homebrew, Debian, Fedora, MacPorts, Nix, Ubuntu, and openSUSE.

### 使用方式

Users configure usernames, domains, parent proxies, and password hashes in cntlm.conf or cntlm.ini, then point applications at the local Cntlm listener. The official site emphasizes authenticated connection reuse, multiple parent proxies, TCP/IP port forwarding, SOCKS5 proxy mode, and running on Unix and Windows.

### 为什么软件包爱好者会关心

Cntlm is significant as a pragmatic corporate-network survival package: small, old, and often invisible, but essential when bootstrap tools such as package managers, Git/SVN, language installers, or build systems need ordinary HTTP proxy access through an NTLM-only network.

### 时间线

- 2007: Version 0.35 brought FreeBSD support, Debian packaging visibility, and built-in SOCKS5 proxy support.
- 2010: 0.91 release candidates tested a major rewrite with standalone proxy behavior, WWW authentication support, Windows installer work, and packaging targets.
- 2011: Version 0.92 appeared with bug fixes and feature work after the 0.35.1 stable era.
- 2012: 0.92.3 and updated manual/WebSVN notes were published while 0.93 testing was requested.

### Related projects

- NTLMAPS is the older Python NTLM proxy that Cntlm documentation compares itself against.
- Squid, Tinyproxy, WinGate, NetCache, and Microsoft ISA Server appear in Cntlm's own compatibility and proxy discussion.
