NTLM? RTFA

In my last post I was testing the Chocolatey package manager for windows and I complained about I couldn't get it to work behind a corporate NTLM proxy server.

Now I had time to test CNTLM. This software is a local web proxy you install in your computer and you configure it to interact with your company's proxy server, so you configure your user, password and domian in the CNTLM configuration file and you 'll never be asked for it anymore! Also this helps programs (like Chocolatey) that have trouble with proxy configurations.

Pros:

  • Configure your proxy credentials once in the CNTLM config file and you won't be asked to re enter them by any other program.
  • Password can be stored as an encrypted hash for your own security
  • CNTLM can work in a windows computer but also works on Linux based operating systems.
  • Unlike many programs CNTLM supports many proxy authentication methods so its best use may be to allow programs that do not support your company's proxy authentication method use CNTLM as proxy and let CNTLM authenticate to the company's proxy.

Usage:
  • Download CNTLM
  • Install it
  • Configure it by editing cntlm.ini (shortcut found in start menu)
  • You can start/stop cntlm with the corresponding shortcuts in the start menu. Remember to restart (stop,start) cntlm every time you finish editing the ini file so that your changes take effect.
  • Remember to configure windows proxy settings to reach CNTLM in 127.0.0.1 port 3128 (default port).

I recommend you reading the CNTML manual in order to understand how to configure it properly, but in case you 're as lazy as me you can also read this stackexchange answer it has every detail on how to configure CNTLM in windows environment:
