CNTLM and NPM behind NTLM proxy on Windows 7

CNTLM

• Install CNTLM in a folder where you have full rights to run it as administrator.

• Open cntlm.ini and fill it :

Username    YOUR_USERNAME
Domain      YOUR_DOMAIN
Proxy       YOUR_PROXY_IP:PORT
Listen      53128

!!! DON'T FILL THE PASSWORD FIELD !!!

• Open a console to generate password hashes :

> cd c:\the_install_directory_of_cntlm
> cntlm –c cntlm.ini –H
Password: ...type proxy password here...
PassLM          D6888AC8AE0EEE294D954420463215AE
PassNT          0E1FAED265D32EBBFB15F410D27994B2
PassNTLMv2      91E810C86B3FD1BD14342F945ED42CD6

Copy those tree lines behin Domainfield. !!! AGAIN, DON'T FILL THE PASSWORD FIELD !!!

• Run the console as administrator and copy the following line to determine if the settings work :
  cntlm –c cntlm.ini –I –M http://www.google.co.uk You should have a success message. If not, check the previous steps.

• (Optional, only if the "Start CNTML proxy" shortcut does not exist yet) Create start_cntlm.bat file where you want :

cd c:\the_install_directory_of_cntlm
cntlm -v -f -c "cntlm.ini"

• Run start_cntlm.bat as administrator to start CNTLM service. Keep the console open. Closing it will stop the service.

NPM

• Open a console and copy those 3 lines :

> npm config set proxy http://localhost:53128
> npm config set https-proxy http://localhost:53128
> npm config set registry http://registry.npmjs.org

• Start CNTLM service.

• Every nmp command should work. You can try with :
  > npm view qunit

• Enjoy.
