Re: [Haskell-cafe] problem with stack behind proxy

FYI.

If your office's proxy server is authenticated with NTLM authentication, use CNTLM http://cntlm.sourceforge.net/ , a proxy of proxy for NTLM-authenticated server. Actually, my last office uses it :)

This works for me as well (though before that I had http[s]_proxy and HTTP[S]_PROXY all set and I think that also worked).

Thank you both for your help!

I have tried to embed a URI encoded username and password in the HTTP_PROXY setting but still did not work. I have managed to find an alternative proxy by talking to the network department that does not require authentication! So now "stack upgrade" works for me too!

I will continue with this workaround for now ...

many thanks! Nikos

According to the error, you must set proxy user name and password to pass the authentication.

Like this:

HTTP_PROXY = http://username:password@proxy-host:8080 HTTPS_PROXY = http://username:password@ proxy-host:8080

Note that you must URI-encode the username or password if they include some meta-characters like a colon or an at-sign.

Besides, stack 1.3.2 is too old!

Hi all,

I am trying to run stack build, or stack update behind the corporate web proxy and I get the following error:

$ stack build Downloading lts-11.1 build plan ...HttpExceptionRequest Request { host = "raw.githubusercontent.com" port = 443 secure = True requestHeaders = [] path = "/fpco/lts-haskell/master//lts-11.1.yaml" queryString = "" method = "GET" proxy = Nothing rawBody = False redirectCount = 10 responseTimeout = ResponseTimeoutDefault requestVersion = HTTP/1.1 } (ProxyConnectException "raw.githubusercontent.com" 443 (Status {statusCode = 407, statusMessage = "Proxy Authentication Required ( Forefront TMG requires authorization to fulfill the request. Access to the Web Proxy filter is denied. )"}))

My stack version is:

$ stack --version Version 1.3.2, Git revision 3f675146590da4f3edf768b89355f798229da2a5 x86_64 hpack-0.15.0

I have set the HTTP_PROXY and HTTPS_PROXY environment variables to a value of: HTTP_PROXY = http://proxy-host:8080 HTTPS_PROXY = http://proxy-host:8080

Can you help me how to achieve proxy authentication via stack?

thank you in advance!
