I am behind a corporate firewall. I am trying to update the conda packages by running :
conda update --all
This is aking me for proxy user name
Got the workaround answer to my Own question. So the necessary file is ".condarc" (content of my file is similar to the one I have pasted in the question). Second, I have asked my IT security team to add the list of web URLs (which conda contacts to for downloading the package) in the exception list. That is it. It is working as of now. Command prompt is not asking for Proxy userId/password. The Urls that i have asked them to add in the exceptions list are :
https://conda.binstar.org/numba/win-64/
https://conda.anaconda.org/
https://binstar.org/
https://anaconda.org/
https://repo.continuum.io/
