What is Cntlm NTLM?

Cntlm is a fast and efficient NTLM proxy, with support for TCP/IP tunneling, authenticated connection caching, ACLs, proper daemon logging and behaviour and much more. It has up to ten times faster responses than similar NTLM proxies, while using by orders or magnitude less RAM and CPU.

How do I configure Cntlm?

Configuring CNTLM. Before you open the configuration file, it’s best to hash your user password (for security reasons), instead of typing your password and saving it to the file directly. To do this, issue the command: sudo cntlm -H -d DOMAIN -u USER. Where DOMAIN is the domain to be used and USER is the Windows user.

How does Cntlm work with proxy servers?

In a proxy environment you use a username and password to authenticate and then access the internet. cntlm will save those credentials to a file and use it to authenticate on behalf of you every time the proxy server demands. Web browsers can be configured easily but this is not the case with other tools as mentioned earlier.

Where can I download Cntlm files from?
